Is The iPhone 4 Proximity Sensor Causing Trouble?

iPhone 4S proximity sensor

Two threads have popped up in our forums, with people noting that the iPhone 4 proximity sensor turns on the screen too easily, which means buttons are pressed with your face, and accidental hangups. Here are what a few people are saying:

Eninety2:

They moved it from the 3GS and it’s not acting right. It’s sensing my ear and mashing the dial pad while in a conversation. You really have to press it against your ear.

neo:

I have hung up on people 3 times already while holding the phone to my ear with my shoulder (hands full).

hitnrun:

Has anyone noticed that the sensor that tells the phone when your holding it up to your ear is extremely sensitive? I mean, NEVER before have I cheek dialed, hit the mute with my ear lobe, or hung up on someone inadvertently. However, 3 times in one call last night and twice today I hung up on people, all inside of a three minute call. I have NOT changed the way I hold my phone when talking by the way. I also hit the mute button several times and pulled up the keypad and dialed some numbers while on the call. I actually told my buddy to stop pushing buttons because I thought it was him…NOPE! All me.

Anyone else noticing this super sensitivity?

Deke736:

I noticed this as well. My first call I hung up on my father-in-law, and my second call I hit the speaker button with my cheek. I thought it was just me.

If you’ve hit this issue too, let us know in the comments or on the forum!

  • Outlaw

    i’ve hung up, muted, speaker phoned and facetimed with people on the phone, all with my own face! this is a huge issue i hope can get resolved. I’m surprised such a thing was not throughly tested or noticed by apple testers.

    • Divarlm

      Ok guys I have found the solution if u have a case on your phone then remove the case and try to make a call and see if this is still a problem with muting, FaceTime, speaker etc the rep told me that my phone case was covering my sensor. Your phone should go black when it goes to your ear preventing you from muting, speaker, or dialing numbers. Hopes this helps

      • Fraz

        Great advice!! It worked. Went to phone and moved part of skin I had for phone and now it works great! THANK YOU!! and thank u Internet.

        • Julia

          Wow!! I wondered what the small cut out above the earpiece on my new phone skin was! Thought it was a mistake so left it in tact-but then this problem arose. Yay for the www indeed :)

      • Laura

        Okay but I have an otter cover on my phone and kinda want to have the safety. However the otter cover is preventing the sensor from sensing-I have no idea why because there is a cut out for the sensor but it doesn’t seem to work. It doesn’t sense the proximity of my ear. I tried with the cover on and off and it is the little clear plastic strip attached to the otter hard plastic cover that for some reason is not allowing the proximity sensor to work. ????

        • Amanda

          Thanks it was my otterbox case. Your post saved me. I was going nuts!!!

          • john

            you can remove the clear window on your case around the sensor and fix the issue

      • Gloria Aymie

        What case did you find that works and does not cover the sensor that is sturdy and protective?

      • catherine hymers

        Thanks you sooooo much – that really works!!! had a picture stick on case and thought the extra cut out bit was a mistake so had left it stuck on – just removed it and it works.

        WOW !

      • IrishBeauty

        I just removed my screen protector and made a call and it seemed to be ok. I will try this out for a few days and see if it helps. Thank you for providing an answer of some sort as this problem was driving me insane!! I use my phone primarily for business so it doesn’t look good when I am constantly hanging up, muting or putting clients on speaker phone!! Thanks again

      • Greatful

        It worked. Quick, simple and desired outcome. I have an Otter box case, used a qtip, some rubbing alcohol and all is back to working now. Thank you!

    • NR

      That fixed … great

  • Frank

    Yup this never happened to me in 3 years of iPhone ownership, and it happened to me 3 times yesterday. I kept putting people on hold or hitting mute with my chin, even happened while I was on the Phone with Apple tech support, hopefully next iOS they will solve this. The case may be playing a role also since the sensor is so sensitive and it pushes the phone slightly further from your ear.

  • Greg

    I am having the same issue I was on the phone and i accidentally hang up cause of my face hitting the end button what is proximity sensor doing :(( how come it aint working the way it suppose to be COMMON Apple what is this IFAIL 4 ?

  • Steve Stein

    Wow, I think Ill cancel my order until Apple gets it together..Why do we fall for their crap every year?

  • Mc

    I’m having problems as well. It’s definitely not like the 3GS. I’m not hanging up but I am pressing “8” often.

  • Eric

    Same here. Yesterday I was talking to someone and I put the phone on speaker. 1st time it’s ever happened with a iPhone and I have owned every model.

  • Gav

    Hadn’t actually made a call until I read this thread. I did so and guess what… I kept hitting numbers. What a pain in the arse. Never ever had this issue with the previous 3 models. Apple get it sorted!!

  • James

    An individual from the apple forums said to go into settings general and reset all settings.. Havnt made a call yet to check it out.

  • Chris

    Really not happy about this. Is this something that can be fixed with a software update? I’m thinking no….

  • Mikey

    I had the same problem and read somewhere else that going into the settings, general, reset and choosing “reset all” fixes it. I did that and have had zero problems since then. Kind of annoying having to put all my settings back again though.

  • Richard

    yes…settings, general, reset, reset all settings fixes this issue (for me). My yellow “blobs” at the bottom of my screen have also now disappeared completely when tested on a white background so 2 of the 3 issues on yesterday’s forums have been resolved for me. Still having bottom left hand corner bar issues though…

  • Jeff

    YES!!!!!

    Same problem!!! I have facetimed, muted, and kepressed all at least 12 times in the first day. Twice just while leaving the Apple store. While using the phone in a dark room, I noticed by simply rocking the phone left or right less then 1 inch the display would activate. Having purchased every version of iPhone on each launch date, I have never encountered this problem. Hopefully a firmware fix….

  • James

    Actually reset all settings hoping for a fix and had the same problem… this is a major annoyance

  • Misie

    Well I don’t have the i4 yet but when I had my 3G I had that problem all the time, calling someone then put the phone to my only to have them answer and hear hello, hello, hello and look at my phone to see my ear had pressed the mute button or while talking to someone dailing someone elses number and never realizing it till the person picks up!!! It was very anoying. Haven’t had the problem since I got my 3GS thought.

  • http://www.patrickmartin.com PatHMV

    I’ve had the SAME problem. It’s being overshadowed by the antenna problems and the yellowing (I haven’t had a problem with the yellowing, and the antenna also hasn’t been an issue for me given the way I normally hold the phone), but to my mind this is a major problem. I can’t hold the phone between my shoulder and my ear at all; that immediately causes my ear to press the FaceTalk button or some other random button or even the nice big “end call” button. I just had one conversation interrupted 3 times because of it.

    I’m sure they can easily fix this in software, and I would expect a prompt update, but sheesh, it’s annoying at the moment!

  • Branden

    I didn’t realize this was a wide spread issue. I have several friends with iPhone 4’s as well and nobody else is complaining.

    Do we think it’s hardware or software? I assumed hardware when I thought it was just me. Replacement is on the way…

  • RyanB

    I’ve been having the same issue, I was on the phone with Apple support and it kept dialing numbers during our call. They recommended a soft reset and then a restore. If that doesn’t work they told me to call back.

  • @YoavPerry

    Add me to that list too. Disconnected on 2 people yesterday withy cheek, switched 4 calls to speakerphone, put 1 call on mute and strangest yet; made an international conference call in the middle of another call. By the time I figured out what happened it must have already cost me $4

    I read that this is related to a synch of older device into this one. The solution is to do a master reset on the unit. Very annoying

  • Mark

    I had the exact same problem and so did my son. Apple told me to backup it up first with iTunes and then select Restore while still connected to iTunes. Haven’t had time to try that yet. Would that accomplish the same thing as Resetting All Settings except your stuff is automatically restored? I’ll let yall know how it works out when I try it later in the day.

    • Mark

      Follow up: Both my son and I did what Apple suggested and it seems to have fixed the proximity sensor problem. I’ve used my phone several times today and did not have any issues with hitting buttons with my cheek. Just to be safe, here’s what I did: first, I connected to iTunes and allowed it to do its normal backup. Then, I hit the Sync button to force it to do another sync. Then, I used the Restore button to basically reset the phone back to factory settings. It automatically then put all my data and settings back the way it was before I started this process. And to be sure I had everything, I then did yet another Sync. Takes about 20-30 minutes altogether, but if it solves the proximity problem, definitely worth it.

  • scraggles

    Yep. Happened to me several times so far. Hung up on people, dialed in their ear, even put one person on hold and called my brother while on a call.

  • JennM

    Yep, just had this problem. I put someone on hold in the middle of the call and noticed that the screen wasn’t blacking out unless I pressed it against my cheek.

    And, is anyone else’s phone getting incredibly hot?

  • Lee

    Same problem here even after a full restore and set up as new phone. I have a genius appt. for tomorrow.

  • otiuk

    i’m new to the whole iphone deal but i’m really bummed with these issues and the fact there is absolutely no remorse or sympathy from Apple/Steve Jobs.

    I have had the reception issue

    I have hung up, face timed, speaker phoned people on accident just holding phone to face

    Not to mention the AT&T service (coming from VZW) is ABSOLUTELY ridiculous there is no excuse for their network to be so bad. Seriously, can’t be in my parking garage, elevator, etc etc when my vzw phone has full service — truly unreal there are people getting rich from these devices and you are meant to alter where you use it when you are meant to use it everywhere. Let me tell you really a HUGE bummer.

    really almost regretting getting this phone – the only solace I have is knowing that my bb tour is always there as a steadfast backup that truly works – everywhere. //k

  • Noah

    The screen’s proximity sensor is definitely not working right. I mute, hang up, or cheek dial almost every call. I just upgraded from the 1st gen iphone and the proximity sensor on the iphone 4 is definitely not keeping the screen turned off like it should. Apple, this is making phone calls almost impossible imho. fix it now please. This is an issue that’s enough to make me switch to a different smart phone.

    • Lucille Decker

      Had the same problem. My screen protector was interfering with the sensor. As soon as I took it off, problem disappeared.

  • http://www.4macsolutions.com Will O’Neal

    This issue is driving me nuts. 10 calls today, and problems with each and every one of them.

  • Geo

    Did someone write Steve Jobs about this yet?

    Flippin complainers!!

    • Mikey

      I’ve written Steve Jobs, no reply yet… Also, resetting all settings only worked for a short time, it’s back to total crap again.

  • Jstall

    There is nothing wrong with the phone. I’ve always hit the lock button on top with my last 2 iPhones, you’ve got to be smart to use this new tech. You’ve got to find something to bitch about don’t ya? iPhone 4 is awesome period. You should take it back and get something else. The sensitivity is the best it’s been! Apple don’t change a thing.

    • Ktownzen

      Idiot with the smart mouth if you hit the lock button the call is dropped…. derp!!!! But thanks for your unhelpful 2 cents er 1 cent…you’ve got to be smart to make comments here!

  • eric

    Same issue. Its not detecting my face and i’ve accidentally disconnected, muted or dialed someone else during the course of a call. I held my hand directly over the phone while its on a call and it doesnt turn off the screen. I assume this is a software fix to tweak the proximity sensor.

    The positive news is that I’ve not experienced any other issues like signal attentuation, screen discoloration, etc.

  • JP

    I’ve also had all thiese (Muted, Hung up, etc.) NO GOOD!

  • Barrie

    Same problem. Keep cutting calls off. Apple have definitely got this phone slightly wrong. Never had this issue with the previous generations of phones. Tried reset but still cutting calls. Spoke to apple offered replacement, but don’t see the point as my friends is doing the same. Definitely a design fault.

    • siddhi

      same problem

  • Eric

    So early in the replies there is a suggestion that doing a rest clears up the issue. I think folks are posting complaints without reading the replies already posted.

    Does the reset work?

    • Mikey

      Seems to work, but only temporarily… I got several hours of use with no problems, but it’s crept back up again…

  • Greg

    Same Problem – I’m confident its a simple software fix

    #######——– Temporary FIX ——–########
    After you pickup the phone, but before you hold
    it to your ear Press the “Lock” button to lock the
    screen. You’ll have to swipe the slider to hangup
    #######################################

  • RD

    Dropped 5-6 calls and put 2 on mute. I called in to apple and after and hour they are sending me a new one. The guy kept telling me that a case would help. I tried “kindly” to explain that cases should not have to be mandatory for a phone to work. If the new one does the same thing, I guess its back to the 3GS…(sigh) although I could probably sell the iphone 4 on ebay for $cash$

  • Allison

    Same problem….and top it off with the antennae problem & I have limited sound (people can’t hear me) with the speaker phone & NO sound to be heard when using the video recorder. RETURN.

  • DoggyDaddyX

    Its definitely more sensitive than in the past. My issue seems to have something to do with my case…took it off and not having nearly as many issues.

  • Jack

    I keep hitting the speaker phone button with my face during calls. This has happened to me multiple times during multiple calls.

  • Palmer

    My cheek has done a lot of things. Facetime, end call, mute etc. I’ve had all 4 iPhones and this one has given me more problems than a pc ( not really, just saying) hope they fix this. Hope it’s only a software problem.

  • Rowan

    Wow I never had any problem with my phone at all. Sorry to hear that for everyone else.

  • Kash

    I have been having the exact same problem. First I thought my phone was dropping calls due to reception issues; got a case and it’s become a “non-issue,” I guess and realized my cheek has been busy causing all kind of mutes, contacts, etc etc etc it’s annoying and the guy who said we are looking for something to complain about probably has no value for money.

  • melanie

    yup, been ahppening to me constantly. i have tried locking the phone on top, it disconnnects my calls, doing the system reset, nothing helps. ihave had ihpone since they came out, every new phone, never had a problem before.

  • Mikey

    *** Resetting all settings on the phone works…. but only temporarily. I have 3 iPhones in my famly plan and 3 more people at work with iPhones… we all have the same problem, we all reset the settings, we all had perfectly working proximity sensors, but only for a few hours… We are ALL back to cheek dialing again! :-(

    I emailed Steve Jobs, I suggest EVERYONE sends him an email and maybe this will get fixed quickly. If anyone gets a reply from Steve, please post the email, thanks.

  • Kaz

    Yep…I just hit star, after muting the call, and even switched out to the contact list after hitting hold…and the call dropped dead like I closed the phone, but I’ll blame that one on AT&T.

  • Jstall

    Dude, it’s not a bug it’s you! And yes I’m aware of the value of a dollar. I suggest you and all your friends take your phones back or learn how to not press your greasy cheeks all over the screen, it’s not that hard.
    The iphone 4 is the best iPhone to date. Maybe apple could make the proximity sensor ajustable for people that like the sensitivity right where it’s at! Then all the whiners can turn theirs down.
    Once your aware of your face touching the screen wouldn’t you just correct it by not doing it? Oh no I’ll send a message to Steve lol. Like he cares. What’s wrong with you people? The phone rocks so just try to enjoy it and figure out how to use it. Get a screen protector for it, that will lower the sensitivity. Good luck. Seacrest out!

    • Gary

      Please don’t post your non-sense.The phone has an issue, period. I will have my phone replaced if necessary, at apple’s expense, unless software fixes it. Apple should address it immediately. This is my first iphone, coming off the blackberry, I never face muted a call, or triggered any alternate programs with my face. The benefits of the phone are apparent, but I use my phone for business not just to play angry birds. SO Seacrest, when you get a job, you may find this to be rather annoying.

  • 19AT4

    I’ve had the same issue…hanging up, but mainly putting people on hold and mute.

  • Field

    I’m having real bad problems with it. Hopefully it can be fixed by a software update.

  • http://fletcherpenney.net Fletcher

    Count me in as well – happened twice in a fairly limited number of non hands-free calls. Never happened with my 3G….

  • 66sweep

    I just spent 20 minutes experimenting with a call to my landline. I pressed the home screen button so I wouldn’t make any unwanted calls in the process. What I found concerns me even more now. I held the iPhone up to my ear, making good contact, so as to trigger the proximity switch. I braced my elbow on the desk to keep the iPhone perfectly still for the next 20 minutes. During that 20 minutes the screen activated 37 times at random intervals. It would remain blank for up about 6 minutes at one stretch and then began to rapidly flash on and off about 6 times then go back to being inactive for another 2 or 3 minutes. All of this with the iPhone held completely still in direct contact with my ear. I tried resetting last night. I even went so far to restore it as a new iPhone. There is no case on it. I’m running version 4.0 (8A293) with model # MC319LL. It almost seemed like something was interfering with the sensor either electrically or thru the software.
    I finally resorted to calling Apple Technical Support. The Level 1 rep said they had nothing listed in their system indicating this is a known problem, at this point. This means there is no scripted trouble shooting steps or solutions beyond what’s already been discussed here. He elevated it to a Level 2 Tech. It appears the only help Level 2 could offer was to exchange the iPhone for me. Unfortunately, the none of the 4 exchange options will work for me right now. The options were: 1 & 2 involved being without a phone for up to two weeks or paying for the use of a loaner. #3 Send me a new one and send my old one back upon receipt of the new one. The issue here was a $700 hold placed on my bank account until Apple receives the old one. Understandable, but just won’t work for me. #4 Go to an Apple store. Nearest for me is 150 miles. So, I guess I’ll use a headset for a week or so until there’s either a software update or I can make it to an Apple store. In the interim, I would HIGHLY ENCOURAGE each of you that is experiencing this issue to PLEASE CALL APPLE so they can better document the issue and possibly speed up their response.

  • Michael

    I went today and did an exchange because I’m having the same problem. Well the exchange does the samething.

  • Guptam

    Same here
    Its unusable.
    I am sure this issue cant be solved with software upgrade. Seems to be the problem with sensor sensitivity

  • Eric

    I’m having the same problem. On more than one occasion I have accidentally muted, mis-dialed, or hung up on a call. It is very frustrating. I hope there is a fix for this issue soon.

  • Jim W

    I have also had countless hang-ups as a result of pressing my cheek against the phone. This was never an issue with my iPhone 3G. I hope there is a fix coming!!

    • Dave Mac

      I’ve had the same issue. Constantly muting people on the phone without knowing!!

  • Jon

    I’m having the same issue.. While on a call: Facetime tries to connect, speaker phone turns on etc.. must be the proximity sensor…
    I have had iphone’s for years and never had this issue… did they move the sensor on the iphone 4?

  • John C

    I got the iphone 4 a few days ago and had only used it in the car on blue tooth. Yesterday on my first call it hit the dial keys, then muted the call then finally hung up. I looked at it in the mirror and the screen goes black when I put it to my ear and randomly comes back on. Then today after going through one of those long press one, press three calls, it disconnected me after I finally got a human. I wanted to throw it out the window!

  • David

    YES!!! My wife and I got the phone last thursday, in just three short days she and I have both had at least 10 issues a piece, when during a call, we wither muted the call, hung up, or in some cases hung up and it dialed another phone number before we even knew what had happened. I just hung up with a senior tech support person from apple and he claimed this was not an issue that apple was aware of. I filed a complaint and he wanted me to stay on top of it and get back with him. My wife came from 3G, which she owned for over a year, and never had this problem. This is clearly an issue and it’s to the point where I might have to take back the phone if it continues!!! Please file complaints with apple so they can take notice!!

    • Ryan

      Please post any info people have gotten from Apple. We are having the same problem.

  • Sean

    I definitely have this issue. Can’t hold the phone on my shoulder anymore. Pretty frustrating.

  • http://tinabean17@gmail.com Tina

    This is happening to me too, at least once a call. Please Apple, fix this problem! Hopefully it’s software related. How could these things not be caught in the testing phase?!?!

  • Brad

    yep same problem here! driving me nuts!

    • kevin wood

      yep it’s bad.. I’m about to fling it out a window !
      I’m seriously thinking of going back to my Droid.

  • Heath Holley

    Having the same problem. Reset the settings and restored the phone, twice, still happens. :-(

  • Tyler

    Same problem here

  • Jess

    I am also having the same problem with sensitivity. I also have difficulty ending the call — when I move the phone away from my head, the screen stays black. This is all VERY frustrating and I agree, I might be returning the phone for the 3GS instead. Is anyone else having difficulty ending calls?

    • http://whats4lunch.wordpress.com/ Nick

      @Jess I have this issue.

  • David

    Same here…I’ve managed to mute or put the call on hold almost every call since Thursday. Never had this problem on my 3gs…

  • Jeff Hartman

    Also having this problem. Just got off a call prompting this search because I pressed the dial pad with my face 5 times through the call and turned the speaker phone on twice.
    Like others have said, I assumed it was the other caller because I have never had this happen once with my old iPhone.

  • Denise

    I am having the same problem. I am hoping when I get my new case this will not continue to happen.

  • eddie

    Having the same problem. Tested with the 3GS and the iPhone 4 and the 3GS shuts off the screen about two inches away from my hand and the iPhone 4 shuts off about one inch away. They (Apple) need to adjust the sensitivity so that the iPhone 4 will also shut off about two inches away like the 3GS did and the problem will be fixed. I hope this is something they can do in software. Are you listening Apple?

  • Jonny

    I had the same issue, settings > reset > reset all settings, worked for me for a while. But now it’s gone back to the lower sensitivity for no apparent reason. Don’t really want to have to reset settings every so often, if anyone knows of a better solution.

    • Ben

      I don’t see how doing this will make any difference to the problem. I have just noticed this and really hope apple are on to it because surely a software update can adjust the sensitivity and fix the issue. Same goes for the signal issue people are having.

  • regbrew@bellsouth.net

    I am having the same problem with my iphone4. My cheek and ear keeps pressing buttons, turning on the speaker phone or hanging up on people. This sucks!

  • Kaushal Mehta

    yes, I am having the same problem with my new iPhone 4. It starts Facetime by itself. Also, it sometimes puts me on mute, so the person on the other side can not hear me. At times, it just presses all the buttons, so both of us hear the DTMF tones.

    I tried to hit the sleep/wake button, which on my 3g used to lock the screen, but the call would not be disconnected. In iPhone 4, pressing the sleep/wake button is actually hanging up on the current call. Need a solution to fix this.

  • Ian V

    HERE IS THE SOLUTION:

    Settings > General > Reset > Reset all settings

    Fixes the proximity sensor issue immediately.

    • Mark C

      Actually, it doesn’t fix it. Myself and 2 friends have reset network settings and still have the issue.

  • http://www.life-engineering.com Rusty Lindquist

    Yes, I keep hitting the “speaker” button, it seems to me it happens when I momentarily pull the iPhone a fraction of an inch from my face, to look a different direction, or something, and then when I put it back up against my ear it doesn’t turn off quickly enough.

  • mad5

    SAME PROBLEMS!

  • Chris

    This is happening every time I make a call. I keep putting it on speaker phone with my face. This is annoying to say the least!

  • Daryle Messina

    Yes, I have the same problem. Very annoying any word if the 4.01 upate will address this issue? Not sure a firmware update can solve problem, which concerns me a bit! I often speak with the phone pressed against my shoulder…while it may not pass the Jobs acceptable method of phone use it’s a problem which needs to be fixed. The reception issue seems to be getting all the attention and I get that but this is a huge problem as well! I have a feeling that many others are having the same issue with the proximity sensor have but many may use Bluetooth etc so it’s not getting as much play!

  • John

    SOUNDS LIKE EVERYONE IS HAVING THE SAME ISSUES… FACE DIAL/SPEAKER PHONE/ETC. I WOULD THINK APPLE WOULD HAVE TEST THEIR PHONES BEFORE A MAJOR RELAESE LIKE IPHONE4

  • Laurie

    I am having the same problem. I keep muting the call. Never ever had this problem with 3G or 3GS. I really hope software update fixes.

  • craig corey

    Tech at apple store told me it was from my case covering the proximity sensor. Seemed to work fine out of the case (Incase clip-on which worked fine with my 3GS). I guess I get to cut out areas of teh case till they design one for the 4.

  • Guy C

    I too have been having hang ups, mutings, keypad activations over my call. Speaker phone comes on by itself. All while holding the iphone and talking on it up next to my ear or with it between my ear and shoulder holding it firm. I have never had the proximity sensor work this way on any of my other IPHONEs, Apple says they will replace but says they have no replacement phones in store, call back tomorrow. I have had no reception problems, just the dialing and hanging up sensor problem.

  • mark travis

    Used a 3g for a year and never had this problem. Hung up on a business contact 3 times in one call and put him on hold twice. Apple needs a fix ASAP.

  • Johann S. Bark

    I have this issue with my iphone 4. Just hung up on someone 3 times in a call. Never had the issue with the 3G.

  • Jeff

    Same here. I know for sure I hung up at least one call while holding the phone with my shoulder. Tonight I put a call on hold somehow — it happened while I was talking normally and then a text message came in. Not sure if the two were related.

    This has never happened with any of my previous iPhones.

  • Bill C

    I am having the exact same issue, especially when I move the phone away from my face to change ears or make a minor adjustment. I keep either hanging up, putting the call on hold, speakerphone, mute, etc. It is REALLY FRUSTRATING.

    I had the 3G since it came out and never had this problem. Looks like Apple QA missed this major problem, because I can reproduce the problem every time.

    Let’s hope they have a firmware fix for it.

  • Eddie

    I have a question for everybody that reads this forum regardless of whether you have the problem or not. Please help us and answer this even IF YOU DO NOT have the proximity problem!!! Does ANYBODY have an “iPhone 4″ that has a proximity sensor that activates further away than 3/4 to 1 3/4 of an inch away from the phone? The 3GS and previous models seemed to have an activate range of about 2 inches away. Please let us know.

    The reason that I am asking is that if NOBODY has a phone that has a better range than the average of 1 inch then it won’t matter how many times I go to exchange my phone because it won’t be fixed until they update the software or firmware or in worst case do a recall.

    I would like to try and find out if this problem is only on some iPhone 4s or if it is all of them and only some of us that use the phone on our ear are having the problem and others are not because of bluetooth headsets etc. and the problem would not affect those users.

  • Andy

    SAME PROBLEM FOR ME…..ALL OF THE ABOVE. I am thinking Apple’s response: Purchase their matching Ear-Muff / Bumper Case … or … simply just HOLD THE PHONE DIFFERENTLY and above all, DON’T MAKE CERTAIN FACIAL EXPRESSIONS and you won’t FACE-DIAL and lose reception!

  • BikeGal

    I have had this problem with the phone since I picked it up – VERY annoying. I’ve called Apple about it twice now and they advised me to restart/restore the phone – which I did and it still happens. I just got off the phone with AppleCare and he said that they have not heard anything about this problem and that until they did there would be no software update to fix the sensor issue. He knew nothing about it – just went on about the antenna issue and how to fix that. He advised me to go into the store to replace my phone if reset/restore doesn’t work. I will go in later this week to see what they think – they’re ALWAYS better in the stores. Maybe if enough people light up Apple Tech Support they will take notice and do something quicker. This is a HORRIBLE glitch with the phone and makes it very tough to talk to someone – harder when its your only phone.

  • CDOT

    Im P’d OFF! this is a great device, but the main feature of it is that its a phone and it doesnt work well at all.
    The sensitivity where you hold it to your face and the screen switches off isnt working well which causes me to hang up, Mute, Call someone else while in call, or start facetime! Called Apple care and had to speak to them on load speaker as i was tired of cutting them off. :-@
    There doesnt seem to be any point in me exchanging it as everyone who has an iphone 4 is experiencing the same issue.
    My fault for getting it so soon i know… but apple should have tested this properly and found this fault. Its not hard to find and i know they couldnt of overlooked this.

  • abacus01

    I have exactly the same problem with the proximity sensor..my calls drop like crazy because my face hits mute,facetime ect. I’ve even seen the phone make the loud noise and goes into auto lock while Im in the middle of the call, which disconnects me..this phone also has blue tooth problems..which is the least of them…apple really needs to come out with a software update hopefully or recall the damn phones until you fix the problems Apple..im ready to throw this phone against the wall.

  • John

    Same proximity sensor problems here. We were pretty much sold a defective phone, and I mean all of us!!! Its just unthinkable that a company like apple would do something this horrible to its loyal customers. This will not translate well for Apple and the longer they wait the more damage they will do to their reputation. We are living in 2010, a bad experience spreads like wildfire over the internet, if there is a consistently bad experience then thats real trouble. Apple needs to make this right as soon as possible and stop denying things….we aren’t stupid and the complaints will just grow.

  • Matt Gallagher

    Same proximity sensor issues, though I just started noticing them today. Muting people or initiating facetime conversations with my ear.

  • Suzan

    Having the same trouble. Thinking about taking it back. I like my 3G s better at this point.

  • Sakemom

    I have experienced the same proximity issue many times and am VERY frustrated. I also have troubles with signal drop from the way I hold the phone and feel pretty upset that I should need to pay $29 for a ‘bumper’ to make the phone work as advertised. I upgraded from a Gen1 iPhone and expected the new one to work at LEAST as well as that one… WTF?

  • Bobby

    I am having the same problem….never had a problem with my 3g. I just got the bumper from apple store and it does not change the problem. This phone is my office and I conduct business on it just like most of you do and it is not helping client relations to have the tones going off in their ears or to suddenly have them muted without my knowledge. This may be the deal killer for iPhones if the can’t get it fixed quick. I’m in charge of deciding what kind of phones to use for my company reps…guess what…I am not impressed. Fix it or lose it!!

  • Suzan

    Proximity Sensor more of a problem if you are holding iphone to your left ear on shoulder then your right ear. Apple has moved sensors to upper right corner as opposed to where it is on 3gs which is upper left corner. When you hold phone to you left ear, sensors are blocked from light and screen goes black therefore you can’t accidently push the wrong buttons.part of the upper right part of the phone is exposed to the light and so screen stays on. the guy at Apple told me that. That means it is internal so how are they going to fix that? They had to move it to make way for front facing camera.

  • Sameer

    I am facing similar issues. At first I couldn’t understand that I am talking to some one on the phone and suddenly that person calls me back saying I hung up on them. It happened 5 times during one call to me. I had to press the phone real hard on the ear and it hurts to keep the phone that way.

    If Stevie says we are holding the phones wrong I think he is looking through his glasses the wrong way. Maybe he is intending to have the iPhones stitched onto our ears for best reception and no proximity sensor issues.

    Stevie .. you eat your lunch and dinner and go to nice parties because we pay you for using your product. If all of us return the iPhones and sue Apple for false advertising imagine where you would be. So please do not give us stupid answers like “You are holding the phone the wrong way”. That is just the most ridiculous answer I have heard. Be a man and admit it that Apple didn’t test the iPhones. I mean I freaking waited in the line for 12 hours just to get this iPhone and now I can’t even make a single call without using my bluetooth headset (bought with my own $$$). Actually Apple should give all of us bluetooth headsets till they fix this problem.

  • Jim

    Yup! Me too. It seems to be much worse when holding it against your ear with your shoulder, however it still is happening when hand held. I have had all 4 models of the phone and this is the only one that is on the verge of being unusable because of hang-ups, mutes, switching to FaceTime, dialing digits, etc.

    Maybe Apple is just trying to deflect some of our dissatisfaction (hatred?) directed at at&t.

  • Meld

    Me to along with 2 work buddies and my wife very annoying!

  • erik

    I was having problems where the screen would wake up after I was done with a call and couldn’t hang up, but after I took it out of my case (which was for a 3gs, until I could get an iphone 4 case) I stopped having any problems, works just like it should during calls

  • Katie

    I am also having the same problem. I have hung up on people, muted phone calls, tried a access facetime. It is very annoying.

  • Dave

    Same here.. every time I use my shoulder I hang up or call someone else.

  • Lindsay

    I am also having this issue! So frustrating!! I really love the new features on this phone, but i am ready to return this for my old 3gs. I am sure they will fix this! Right???? I am going to visit the store in the AM. Wish me luck!

  • Jake

    Just adding that I’m having the same issue. I hope there is an update that will fix this.

  • Rachel Finsbury

    I have the same problem but I have been told that is an unkown problem and that I should take it to an apple store to be looked at. Never had this with my iphone 3g.

  • ruj

    same promlem…annoying

  • Eli Wett

    I am having this smae problem; inadvertantly hanging up, getting a mute, and also launching facetime due to this problem. What is the solution?

  • chryl howard

    the very same problem..i have to call people back at least three times ..r i hit mute and so on. apple said it was the case i had it in .so i took it off and it works better but it will still do it sometimes. never had this problem with my other iphones.

  • jeff k.

    a little video i did to demonstrate the problem.

  • Eddie

    This workaround is working so well for me I just wanted to repost it with additions.

    djkidkaz wrote:
    I think I may have found a temporary solution to our problem while we wait for a real fix from Apple.

    Once you start a call, hit the home button and pull something else up on the screen like a photo so that if the screen comes back on it doesn’t have options like END CALL or FACE TIME on the screen to accidentally hit. The calculator may be another good choice as the only way to get it off the screen is to hit the home button.

    Just wanted to add to this. >>As soon as you initiate a call you can double click the home button to bring up recent items and then just hit the photos or whatever you were using as a quick shortcut. It will take you right back to whatever the last photo you had up and you can go to your call.

    You can also use the double click on the home button while you are on the call in the photo app to view recents and then toggle between the phone app and the photo app if you need to get back to the call screen.

    We definitely shouldn’t have to do this but for people that absolutely need their phone without headphones etc.. this was a great suggestion!

    This is working for me so far at least as a work around.

    thanks djkidkaz!

    • Aaron

      Thanks Eddie for the repost. It works but, you’re right, we shouldn’t have to do this.

  • Anna

    Same problem… my phone keeps trying to connect to facetime while im talking or muting my calls

  • walt

    Same problem, can’t talk with out jawbone or speaker. calls, mutes, speaker phone, add a call, hang up. . . . constantly

  • keith

    sigh, i hate this, my old iphone NEVER had this problem, I constantly have this problem with the new iphone 4….fucking apple, I shoulda went with a different phone.

  • brattyb

    OMG. This is making me INSANE….I was talking to my Dad who is hard of hearing anyway, and MUTED our conversation 4 times!!!! Everytime he couldn’t hear me, he thought the call ended and hung up! The another call beeped in and my ear apparently switched the call over for me, how delightful! This is not making me one bit happy and this needs to be fixed asap!

  • markdemaio

    I had this problem and it’s easily fixed. Go to general, then settings and then hit reset, then hit reset all settings, you wont lose your data or info, it just resets the phone, it only takes a minute. You’ll have to reset your wi-fi password and ringtones and wallpaper but it solves the problem right away. I did it last night and been working great, and not related but i haven’t dropped one call, i think the phone is amazing, that mute button was my only issue and this fixes it so…there ya go!!!

    • bdaley

      Tried it…doesn’t work.

      • Aaron Hunter

        Yeah, that doesn’t work for me either. I think it’s a hardware issue. Not something that can be resolved by resetting the phone.

    • ina

      it’s work for me, thank so much

  • francis

    mine keeps doing the same, almost every call this is happening!

  • Jamie

    I’ve experienced this in nearly every call I’ve made. My cheek bones have hit mute, browsed contacts, hit facetime and even ended calls. I’ve had the phone for 3 days! I went to my local apple store in Seattle (University Village) and the tech immediately said this was a known software bug that Apple is working on. She took my serial number and said to wait for the update, and if I still had issues, to come back, noting, “nobody will give you a hard time.”

  • Craig

    This, to me, is a way bigger issue than the antenna. This happens all the time. I’m really hoping this can be fixed through a software update because this one issue is enough to return the phone. It messes with 75% of my calls and it didn’t happen once in my year with the 3GS. It’s obvious what is happening. The sensor is just too sensitive and doesn’t cover enough area around the phone. Call Apple at 611(airtime free) and just put your finger around the area and then do the same thing on the 3G or 3GS. It’s nowhere near the same.

    • Aaron

      Yeah, I think this is a huge step backwards from the 3G or 3GS. I’m going to blame poor placement of the front camera. The sensor is on the same side as the camera and it’s obviously affecting how the phone is responding to being used when next to your ear. I might have to go back to the 3GS until they fix this.

  • Alex

    I have fixed my proximity sensor and can make calls without hanging up/muting etc

    I was having severe problems with the proximity sensor on my iPhone 4.
    During calls my ear was hitting mute, end call, face time etc.
    Today I had the hardware replaced at a retail store and restored a backup.
    The problem remained.

    Then I read a post on this site suggesting resetting the network settings and thought, why not, Apple had no fix.
    Before I started I tested and recorded that the proximity sensor required my hand to be about 5mm above the sensor before it kicked it and blanked the screen. This is too little if the sensor is in the centre of my ear.

    Then I used Settings/General/Reset/ Reset network settings.

    After this the proximity sensor worked at about 3cm under exactly the same conditions.
    I have continued using the phone including setting my wifi password which had been cleared.
    I have no more problems.

    It might simply be the reboot that fixed the problem so try that first.
    Point is it’s not a hardware but rather a software issue, on my phone at least.

    • Aaron

      I beg to differ. I think it’s a hardware issue. The sensor is located at or around the speaker. Which means, when the phone is held against your face and you’re listening to what the person on the phone is saying, the phone doesn’t realize it’s still being held against your head. Dial 611 from your phone and use your finger to check out what I’m saying. When you put your finger over the speaker, the phone locks. When you move it away from the speaker, it lights back up. It’s a major flaw and more irritating than the “reception issue” (which I haven’t had a problem with).

  • Mark

    I think everybody should have a look at this post that was deleted from the Apple support forums by Apple. It seems that they have no interest in fixing this issue or even making a statement on it unless they are forced to by a lawsuit or something to that effect. I am VERY disappointed in Apple. I have been a fan for over 15 years. It seems as if they have forgotten who they are and just becoming a big bully now. (see below)

    Wow just cause of this attitude of apple employees They are being SUED by lawyers well apple you should take this time and save yourself from another class action law suit for proximity sensors

    PS ~ Apple mods now don’t be wasting your time deleting this post since I have a right to say stuff when you guys sell us your defective product and I think if apple doesn’t address this issue then we all should return the Iphone 4 at lease those who are having this proximity issues.

    And also apple instead of deleting peoples post how about investigating why Iphone 4 proximity sensor is going haywire and maybe you will save yourself from another law suit and also people who are having problem with there iphone 4 with the proximity sensor do report it to KCR LEGAL LAW FIRM

    http://kcrlegal.com/iphone-4-class-action-lawsuit.aspx

  • Joe

    Happened to me too. i also have had the phone overheat 2 times that it even showed Temperature warning on it. I think I got a dud!

  • LB

    Mine does the same thing. Face dialing, muting, ending calls, etc, and the display flashes on and off while the phone is pressed to my ear in a very distracting way. This is my second phone. My first phone locked up after my first sync and the Genius techs couldn’t fix it.

  • Ghud

    Same issue here folks! I thought it was just me. The techs were probably instructed to say they haven’t heard of the problem. Because if it’s a hardware issue, they’d wouldn’t be able to fix it and would have to recall! I’m just sick of having conversations by myself while the phone is on MUTE! Ridiculous design flaw!

  • SamBam

    Yeah, same here, its been happening with the mute button a lot more frequently with this iphone, but not with my 3GS, really annoying. I had people hang up on me because they couldn’t hear me.

  • kapil

    I have the same problem, it keeps dialing either a number or facetime or switches on the speaker.. its ridiculous..might send it back..

  • Mark Siegmund

    Definitely have the same problem. I constantly inadvertently press “mute” or “facetime” with my ear while on a call, and this was never an issue with the iPhone 3G. I don’t want to have to break out my headset, or have to toggle to a different app, every time I want to make or take a call.

  • Jon John
  • D18unk

    Oh i do wish that i did not sell my 3gs, am gutted and very p….d off with the i phone 4.

  • Simon Hancock

    this problem is a serious design flaw and i use my mobile for my business so its just becoming ridiculous having to call people back numerous times.

  • socwrkr

    Same problem – SO ANNOYING!!! I’m always hanging up on someone or muting myself when I am trying to multi-task and use my hands for something other than the phone.

  • js

    Always hitting the mute or dialing numbers – Hope they can fix it!!

  • Ann

    Same issues as everyone above. Just got the phone 2 days ago. I thought I was nuts for the first day- I would continue talking and the other person could not hear me. Phone was on mute. Also somehow had ringtones starting up. Dialed numbers I didn’t want to call. Hung up on people without meaning to. And, my daughter’s phone has the camera issue: either the shutter locks or it turns the phone off when you take a picture. I called Apple today (spent 45 minutes on the phone), trying to “fix” the camera issue (didn’t know it was so well-known until I found this forum and others). They originally told me I would have to pay $30 shipping fee to have a new phone exchanged out and sent to us. I refused and asked to speak to a supervisor. Only after threatening to sue was the $30 fee “waived.” Needless to say, I am not real impressed with Apple or the iphone4 right now.

  • Ben

    I repeatedly turn the loudspeaker on, several times during a single call, hanging up is rarer, but still does happen.

  • Lusso Forged

    Driving me nuts, same problem here on every call.

  • DAniel D

    My wife and I both have the new iphone 4 and she is constantly hitting the mute somehow when on the phone.

  • David M

    I’ve got the same issue I keep cheek dialing.

  • Rob C

    Same issue’s here. This is my 3rd Iphone and the worst yet.
    COME ON APPLE your supposed to be good at this stuff…..

  • ryan

    shut up and quit whining… its a phone… a revolutionary one packed with technology thats new to the mobile electronics industry. just be patient and apple will release a fix sooner or later, wether it be a hardware or software fix. do you think that a few thousand phones out of the over 3 million they’ve sold is their top priority? obviously the proximity sensor functions, its just in a different location… adjust you holding habit, and guess what! the problem is fixed… if it sucks so bad just go buy a blackberry… im pretty sure apple would survive without your business. and im certain that the techs at the retail stores will be pretty glad that one less whiny prick would be coming into the stores…

    • jbr658

    I have the same problem. This is scary. Has Apple stopped testing before release?

  • nicole

    Me too! Missing my old iPhone…and I was so excited to get this new one! =( Adding my name to the list.

  • tedg

    i cheek dial all the time. i hang up on people constantly. what do i do. i already broke one iphone4 i cant afford another.

  • Judi Smith

    Same problem, only now mine goes to my ringtones, and plays music in my ear while i’m trying to listen to people talk or hangs up or presses hold. I’m so upset I want to cry!!!

  • Mandrake

    Same exact problem. Kept happening whilst on the phone with my nan. Everything when it comes to this new screen is just too damn sensitive. For now, I’ll do the calculator thing, but apple better figure this crap out!

  • Scot

    I am so fed up with my new iPhone4 muting because my cheek inadvertently presses it on almost every single call!! My business associates and customers think I keep hanging up on them!!! This is just ridiculous!!! This is my first iPhone and I can’t believe this basic design flaw actually passed Quality Control!!!

  • sean

    i had the same exact problem. every single call would mute, hold, conference, or hang up. it was getting out of hand. so i went over to t-mobile and got a white blackberry bold. i think you guys should do the same too. i never have any problems and i pay $100 for unlimited everything!

  • http://hotmail.com Robin

    It has been reported that reason fir the fault is because of sweat from you ear, the phone was fully tested at china factory and this fault never arose because chinese people do not sweat.

    • minivini

      Could you post a link to this report? “…chinese people do not sweat.”? That’s the most moronic statement I’ve ever read (with the exception of virtually everything that comes out of Rush Limbaugh’s mouth).

      If this is not a joke you should seriously consider removing yourself from the interwebs and check into rehab somewhere…

      • Perplex

        Minivini, i think what Robin meant was, Chinese people don’t sweat — They glisten. ;)

  • Jordan Zimmerman

    This is driving me crazy! The iPhone 4 is an order of magnitude worse with it’s ear sensor than previous iPhones.

  • Schmavo

    WORKAROUND………use the lock screen button (top RHS) when on a call

  • adam

    I have the same problem. Not only have I hung up and muted people countless times, I have accidentally called people while on a call and and set up conference calls. I do not use this phone to make important calls, as I do not have complete confidence in it. I totally fell like my 3gs is superior to the 4g, I wish I still had it.

  • Robert

    I am having the same problem. It’s just plain ridiculous. Within a 3 minute call, I accidentally hung up the line 2 times. It’s happening every single call I make. I am now using the Speaker to talk on the phone. I am so unhappy with my Iphone 4 now.

  • Keely

    Glad more of you are out there. I thought I was going crazy. I use my phone for work ALL DAY. And I have felt like a crazy person talking for minutes then noticing I’m on mute. Facetime always pops up too- then when it doesn’t work it hangs up the call. can’t this be a software update Apple will do! PLEASE?!?!?

  • Cedric du Trevou

    I have the same problem .
    Hope that it is a software issue .

  • Denise Phillips

    Having the same problem. Got the phone last night. Made a call today and while trying to talk I muted her multiple times, put her on hold while it dialed the last number called, put it on speaker, and tried to connect to face time. Absolutely ridiculous! We should not have to toggle to another program to keep this from happening. Very disappointed.

  • val

    omg i have the same problems its rediculous i cant get through a call without hearing my ipod playing songs or my ring tones scaring me to death its very annoying

  • lucaF

    I have the same problem on my iphone the proximity sensor does not work well and I often touch other buttons during a call….

  • Roxanne

    OMG I decided to search this issue and to my surprize im not alone! This shit is annoying!! Im 3 way calling, face dialing, muting my calls, ending my calls! I cant take it this is frustrating!!!

  • Ron

    I totally agree….it’s sick. Always putting myself on mute and hanging up on people. I have to keep them on speaker phone all the time just to talk to someone.

  • Steven

    This is a very annoying issue to deal with. It makes using the iPhone 4 not fun at all. I now find myself afraid to take calls or make calls for fear I will inadvertently hang up, mute or digitize someone into oblivion. Just tonight on a 10 minutes call, my ear must have hi the digital key pad several times making the annoying beep! I hope there is a fix for this!

  • new iPhone user

    I cannot believe the whining I am reading. I have yet to “three way dial” someone. But I do have a simple fix for those people who’s lives have been ruined by this awesome phone….. Go get a flip phone!

  • Bryce07

    I am a new iPhone 4 owner and me and my wife are having the same problems we never had this problem with the 3G and 3gs…very annoying!

  • Jo

    I’ve actually got the new version of the software and am still having this problem. Perhaps my phone is actually faulty. I’m glad I looked the issue up as for weeks now I have been wondering whether it was just me holding my phone in a silly way!

    Also, a message for Steve above: its not “whining” is “discussing”. Thats what discussion forums are for and if you’re sick hearing of it then why look up the issue and read posted messages about it?! Ultimately its called an i PHONE, and the whole basic point of a PHONE is so that you can call people. Therefore is it any wonder that people are a bit frustrated at having a phone that costs so much but yet has such a basic flaw.

  • N

    As am I. This is truely frustrating. Always hiting mute, hanging up, seeing my mug on facetime when I can’t figure out whats going on… Hate this phone.

  • N

    *truly

  • Teressa

    Google search sent me here, glad I am not the only one having this problem. I’m a first time iphone user, and I got my 4 yesterday. Going to keep searching for a solution, I guess. . .

  • bubba

    Dude!!! THis happens to me all the time!!!!!!!!!!! Can’t they fix this with a software update? What a crappy job by ol’jobs

  • sven

    Jævla irriterende dette ja. men det som er ennå verre er at tastaturet har blitt helt håpløst og nekter å komme med rett bokstav når jeg skriver sms, ofte dukker bokstaven som er 2 hakk bortenfor den jeg skal ha, opp og det er sinnsykt irriterende. Flere som har vært borti dette???

  • Kevin

    Is there any way to just turn the mute button off? I dont think I would ever have a use for it. EVERY single call I make I eventually hit the mute button, it’s driving me insane.

  • Matthew

    I’ve been having a problem with pressing the mute button with my cheek/ear. Haven’t had any hangups or 3-way calls though.

    There is an easy solution though – after dialing/answering, press the home key so the menu disapears.

    Also agree with one of the comments above – there should be a software update so the mute/end/3-way buttons aren’t easily pressed.

    • Chris

      There is a pretty easy fix for all of this, when you are on the call push the phone button which will bring you back to your home screen and remove all of the above mentioned buttons altogether. When you need to hang up touch the banner at the top of the screen to bring back the call screen and hang up. It is a pretty simple fix, though I must admit it took me a couple weeks to figure it out.

      • sandy

        I tried going to the home screen. It didn’t work… my ear pressed on an app and when I was done with my call the apps were jiggling and I was being asked if I wanted to delete the app.

        Does anyone have a solution?

  • Paul

    I have just called apple – I am not accepting “all you have to do is press this or that” . It’s a phone, none of the previous models exhibits this behaviour. The girl on the support line verified my warranty and claimed to know nothing about the trait we have all seen.
    I am going into the apple store in Milton Keynes to see the person try and get out of this in person.
    Monday I am calling trading standards – this phone is not fit for the purpose it was sold for.

    I am having to go back to my 3GS, so frustrated by this issue.

    I am a new Iphone user and honest I should say this phone is very “user unfriendly” (maybe I am a new user, but I think Iphone did not design good).
    First, when you are reviewing Recent calls, if you finger touches anywhere accident, a call is making out!
    My suggestion is when your finger touches any number, one has to push “call” button again to initiate the call. So if you touch a number by accident, you can still cancel the call.

    Second, I had similar problem mentioned above. Call is cut off by ear, call is muted by cheek.

    Third, there is no way to turn off the tone of numeric keypad when you dial.

    4th, when you enter a contact, if you don’t put in home email address first, then work email address area shows up. What happen if I just want to enter contact’s work email only?

    the list can go on and on.

  • Kay

    I’m glad to find that we’re all not alone, however, I’d love to see if anyone out there has solutions to the problems???

  • Steve Jobs Hater

    Sure you can push the home button every time you get or make a call but why should you have to! fix the damn phone Steve!!!!

  • foz

    PAUL – I’m having the same issues mentioned here and live in MK too.Only had iphone 4 for the last two days. Was going to book in to see the guys at apple mk too. Would be so great if you could let us know what they said..

    Many thanks in advance!

  • Christian

    Very annoying indeed! Had the 2G before and never experienced any problems. Now whenever I’m on the phone I keep hitting the mute button with my cheek. Pretty hard making normal conversations like that! So please Apple, wont you pay some attention to this problem in your next firmware update?

  • Wottha

    I am just adding my voice to the frustration on muting people when I talk. I now have to hold the phone away from my head. Not good enough Apple, please fix.

  • Floyd

    yeah, why should we pree the home button to enjoy our iphone????
    pls apple, sort this out !!!

  • Tammi

    I am completely irritated with the iPhone 4 and I am not new to iPhone at all. I had the original one then the 3GS before this one. Then when I was experiencing the problem with the proximity sensor disconnecting, muting, three way calling, etc. Apple swap my first iPhone 4 for me. Well to no surprise that did not resolve the problem. As I’ll bet they knew. That was just an attempt to stall, humor, or pretend to make an attempt to please me. Frustration !!!!!!!

  • DavieManchester

    Just googled this subject!

    This is happening to me all the time. Keep putting my friends on mute.
    Never did it on the iPhone3.

  • Mike

    I have been having the mute problem for some time now. Also if you go to the home screen it starts opening apps. So annoying. I have been loyal to apple for a long time, but this is wearing on my last nerve!

  • Mike

    Same deal. Hang ups (most common), speaker activation, face time activation and even conference call initiation. Called Apple support who got me to test the proximity sensor by placing my hand over the top while making a call. Worked fine of course! Can’t use this as a serious business phone.

  • Petter

    Same here.

  • Chris S

    I don’t know if this is a venting forum or a support forum. Its obvious many of us are having trouble with the proximity sensor, but bitching about it is a waste of energy. Does anyone have a solution?? Apple??……Apple??…….Apple???…..

  • Eric D

    Hey Apple, this problem is very real! I’m tired of my cheek placing unnecessary calls and hanging up on my clients. Fix this already!

  • pacificwinter

    Yep. This is a real problem and I hope Apple provides a fix. I have had my phone for about a week and have had several hang ups because I was on mute and had no idea. This is my first iPhone and I love the functionality but can’t believe Apple released a phone with this kind of serious bug.

  • dave

    I took my phone back to ATT, there is a software/firmware update that fixed my problem. Open your iTunes that is kept on your computer and backup your phone completely. Then from the iTunes ‘Summary’ page do the ‘Restore’ function. Your iTunes on the computer will download an entire new software program for the iPhone (about 500 mb file). Just follow the onscreen prompts on your computer, leave the iPhone connected the entire time. After 2 restarts you will need to re-sync everything, your Apps, Music, Podcasts, etc. This will take about one hour of your time but will fix the problem with proximity sensor when you are using the phone to speak to someone else.

    • Bryan

      Thanks Dave, I will try this and update the thread this weekend!

      • Bryan

        Good Find Dave! IT WORKED!

        I also saw other performance issue disappear. Thanks Dave for posting on this issue!

    • Rob Perth Aust

      Brilliant dave, proximity hangup, mute problem all fixed for me with update 4.2.1,
      Thanks for posting your fix.

  • sb

    I attended an phone interview on my new iPhone. It was a disaster – my ear lobe/cheek muted the phone, turned on the speaker and dialed my home phone. I had to call them back multiple times. Yes, this is a big issue.

  • Tina

    I am on the verge of smashing my iphone..last night…i hung up on my bf 6 times…hung up on my mum 3 times…i basically hang up…mute….speakphone….3way call…facetime…nearly EVERY time…it pisses me off so badly..i went to genius bar..but..argh..on that day…it ‘worked’ and basically after a seconds of ‘testing’ he said it was fine…its a horrible phone…

  • Lisa

    Perhaps the most frustrating thing about this problem (has happened on my 2nd phone in 30 days) is when the manager at the Apple store implies that I don’t know how to hold/use a phone. “How are you holding it?” “Um, like normal people hold a phone to their ear.” “Well that shouldn’t be happening on a 2nd one. Mine works fine.” That’s great – I hope my 3rd one will work fine, too, Mr. brilliant and customer-centric manager.

  • m ryan

    the part i find most frustrating besides the condescending hipster service jerks of course is the glitch prevents you from hanging up.though it turns on the screen while talking it seems to turn the screen off just as you move it away from your face to hang it up. sometimes pressing the home button wont work at all for several attempts usually it turns the screen on for a split second then off again over and over while you curse at the phone and the person still on the other end of the line. 90% of the time the problem is solved by them hanging up while you spend several attempts trying to determine if its definitely hung up or not.
    frankly besides the camera flash i havent found anything i like better about the four than the 3gs and am going to make them take it back this is my second four in a couple months besides all this the first one lost use of the microphone altogether and because of the constant ceek mute etc and significantky poorer reception than the three it took a week to realize it wasnt simply those issues.maybe its time to give android a try.i HAAAAAAAAAAATTTTTEEEEE i tunes and am not a mac user,though i did love my three g and three gs when i didnt have to use itunes.

  • ami

    Googled this issue…I have the same problem!! It’s extremely frustrating!! It is the ONLY feature I hate about this phone- everything else is great!

  • Alvin

    Hmm, may I suggest that anyone who is having these problems to hold the phone to your ear with the bottom part of the phone around 1-2cm away from your face. This way the cheek will never make contact with the phone at all. I always do this when making calls mainly because I don’t like the feeling of the phone being stuck to my cheek. Because of this, I’ve never experienced any of the problems many of you guys are experiencing since I bought the phone. Just my 2 cents. Hope it helps :)

  • mootman55

    I bought the iphone 4 and the same problem is happening to me, i hit speaker phone with my cheek
    i constantly move the phone around my ear but the srcreen keeps coming on. i will get use to it, i love ths phone so i will get over it.

  • Greg

    I have had this issue since the day the iPhone 4 was released. Awesome technology – but this one flaw makes it critical to use a headset all the time. I’ve gotten used to the headset but, this is just wrong- apple should not discriminate against people who’s ears are shaped differently…

    I dont understand why they cant just change the software so that pressing the “sleep” button on the top of the phone triggers the phone to “lock” this would fix all our problems, just swipe to re-enable your keypad… instead the sleep button hangs up the call.

  • Bryan

    Be Sure to try “Dave’s fix” up above, it worked great!

  • Fix It!!!!!!

    same problem. mute, voicemail, hangin up, hold, three way calling, face time, different apps. please fix this problem.

  • Jenna

    OMG this is SO annoying! During EVERY SINGLE PHONECALL I put the other person on mute, on hold, or even start calling random people from my phone book SEVERAL TIMES during a call!! Most annoying thing ever! What’s the point in a super high-tech phone is you can’t even make PHONE CALLS!! This has really angered me. I’ve never have an iphone before. Always wanted one. Spent over a year saving up for this extortionately priced item only for this to happen!! My bf gets really irritated when we call each other ‘cos this happens every time! SORT IT OUT APPLE! I want my money back!

  • Binho

    Please please please fix this… it occurs on EVERY call… it’s driving me insane!

  • Jmorg1980

    I have the exact opposite and it drives me crazy. If i am on the phone and want to do multitasking or even end the call, the screen continually goes to the black screen and won’t let you push buttons.

  • iPhone-sux

    iPhone-users (or should I say, iPhone-losers),

    Apple make the most superb line of computer equipment (iMac, MacBook Air/Pro, iPad, etc.), and undoubtedly the iPhone is a huge $$$ success for Jobs & co., but iPhone in particular, and smart phones in general, have to be the crappiest concept around. Too big to make a good ‘mobile’ phone, too small to be a useful computer and too complex to use ‘out of the box’. This whole proximity sensor issue is just one example of many that that highlight the inappropriateness of this kind of ‘phone’. If you want a decent mobile, buy a simple mobile. And then get an iPad! Cheers suckers!!

  • iPhone-sux

    …And another thing…

    So much for being a ‘smart’ phone – the damn thing can’t even give you a simple log showing how many minutes for outgoing calls, it just lumps call time in one grand total, leaving you to manually scroll through the call history and count up your minutes!!

    Maybe that’s ok for the US where you pay for each minute no matter what. But in most other countries you don’t pay for incoming calls, so you want to know how much time you’ve used for outgoing calls, especially if you get free minutes each month to use.

    Regardless of that, a ‘smart’ phone should provide a plethora of ‘smart’ features, not just the basics. iPhone – what f@?&ing waste of space!!

  • Chris

    Thanks Dave, your solution worked for me. It was worth the time it took because cheek dialing was driving me crazy.

  • tyrell

    when ever i call someone and put the phone up to my ear the screen shuts off and sometimes it ends the call. So when the screen shuts off and im done talking the other person i can’t end the call..this is a little annoying when im dealing with automated services that need me to press a key to get to a department or connect to a specific person because i cannot access the touchpad due to the screen being turned off, and then after the call finally ends i can’t use my phone unless i force reset it.

  • D Fedson

    I agree with m ryan…the most frustrating glitch is the one which prevents one from hanging up, or ending, a call. The screen goes black (not even to sleep…just black), and when the phone is awakened and unlocked to end the call, the screen goes back to black. And, when the off button is pressed, it isn’t possible to slide the button to “off”. Instead, the screed goes black. I’ve tried Dave’s solution, and this issue still exists. Any other ideas out there?

  • Xin Ye

    I just updated the phone with 4.2 version of the software, the sensor works fine. I read the Apple support site, they should you how test. if you dial a number, hold the top 1/3 of screen, the phone screen should go blank. Now it does. the upgrade process is very easy, as long as your use iTunes.

  • hyung

    My cheap phone never has this problem.. I turn to iphone4 and also face this problem.. Very annoying..

  • Mike Powell

    Yep have this issue to mostly it is the phone going to mute. Sadly my phone is now also refusing to talk to itunes at the moment, no idea why so I can’t go to the new software. I want to buy equipment I can just use the iphone 4 is way to high maintainance.

    The phone would not be bad if it was easy to sort out all of these issues but Apple’s service and attitude is so bad I will not buy Apple equipment again. They make Microsoft and other phone manufacturers appear customer carring by comparision.

    I guess until people stop buying their kit they will carry on not bothering.

    Would be good if apple had someone commenting helpfully on these threads but my expectations now is that they would just be condesceding and deny any issues existed.

  • ginger

    I too am having an issue with cheek muting…my cheek keeps hitting the mute buttons and other buttons…is there going to be a fix for this?

  • Rick

    I fixed mine. I fixed mine.
    I have read all day about people with the same problem as me. Ear Dialing. Ear Facetiming. I hit mute, speaker phone and I call people without meaning to.
    I talked to the fellow at the AT&T Store and he was frustrated because Apple ignores the problem. He understood my frustration and tried to give me all the answers that his job called for.
    I finally went to WalMart and bought an Incipio Case for it. It was on sale for $12.99 from $19.99.
    It would been a bargain at $19.99. The proximity sensor problem is G O N E.

  • AVos

    I had this problem too. When I was on calls I would put people on hold, on speaker, or conferecnce call other people. I thought it was just my face or something (!) but then I went into my local apple store and apparently it is a fault with the iPhone from the manufacturer. It means the proximity sensor needs to be replaced (and as usual with apple, they just gave me a new one) NO more problems with my new one!!!!!!!!!!!!!

  • Kevin Martin

    Yes this problem is annoying. My wife says I’m getting fat. I found a workaround.. each time i make a call, after pressing the Call button (or when receiving a call, after pressing the answer button) I immediately press the dial pad button. That way, instead of muting the phone while talking, the worst it does is pressing a button.. (and the annoying ‘beeeeeeeeeeeep’) usually is just the number 1… although my cheek some times presses 6.
    hope this is useful for someone..

  • Dick shaker

    It happens to me every day 4 or 5 times a day very inconvenient

  • Chick

    Total pain in the ass. DAILY I have been muting calls or hanging up on people!!!!!!!

  • Richard

    I have all the above symptoms. I have even snapped a picture or two. My son and his wife have the same phone and don’t have any problems with theirs. Guess I got the lemon.

  • Murty

    Last night I was using my friend’s phone (iPhone 4) to attend a conf call at work. I was on mute for the portions I am listening and people were still complaining that there is some background noise. But everytime I look at the screen it shows that the mute button is on. Couldn’t understand what’s happening and looking at this forum, I guess, it’s an issue with hyper sensitivity.

  • Ammar

    Yeap! Same problem here! I have it on two iPhones 4! Two friends also have the same issue! Seems Apple is becoming sloppier as they seek more profits, more so than caring for good quality as they used to!!

  • Heather

    Yes having the same problem! Now how are you going to fix it?

  • sang kim

    I have same problem , finally ifixed

    here,s tip ,,,,,when make the phone call, screen shows sensor, then touch the keypad button
    and talk, then no more problem. ……………….

  • Jbin

    I think I fixed the problem by thoroughly cleaning the phone. I had been having this problem for weeks. Read this forum and realized maybe the sensor was not sensing when I was on the phone. I am a contractor and have the OtterBox but still get a lot of dust in every opening. I hope that was it…was going to throw it out the window if muted me one more time while on the phone with a client.

  • sridhar

    I have the same problem too. Pretty new iphone4 (about 3 weeks) and it keeps bumping the mute button.

    Exactly where is the proximity sensor – was wondering if I can clean it.

  • Ben

    Having the same issue – it’s absolutely unacceptable. This came up in June 2010 and it’s now April 2011 and the issue is still happening. Mute keeps activating on every call i’m on. Not happy at all.

  • Eric

    I’m having the same problem and it’s driving me nuts. I have an otterbox. Will try without.

    Where is the sensor?

  • Collett

    I’m having this problem muting, FaceTime calls while talking, holding calls, … I never had this problem with 3G but my iPhone 4, it’s a daily problem. Apple just replaced my phone for other issues so I have had this new phone less than a week and it’s muting, holding and facetiming calls..

  • J

    Yep, just got the phone. Same thing. Is there even a sensor on this damn thing? Seriously……

  • Lucy

    I’m having the same problem with the screen not turning off during a call.makes sense with the comment about the case blocking the sensor.I bought a true otter box case for mine and didn’t like it so I bought one of the knock off cases and didn’t start having the problem until after I put that on

  • seb

    just change the case and make sure the new one does not go over the proximity sensor located right on top of the screen

  • Teresa

    Same problem. Returned the phone to apple store they gave me a new one only to have the same problem. This is the most frustrating thing ever. My husband has the same phone and never had a problem.
    So its not all iphone 4s just some of us and what are the chances of returning and getting another one and it has the same issue. This is a serious issue some have commented on holding the phone right, they need to take my phone for a day I bet they change their attitude towards this problem.
    I have 14 days to return to verizon so it is going back.

  • Linz

    Just got the white iPhone 4 last week and have had an issue with the proximity sensor. Have been muting, holding, dialing other numbers and hanging up on people. Really frustrating, especially when I hung up on my partner’s Mom while she was telling me they found her brother dead. Not cool, Apple, not cool.

    • Geoff

      Have you contacted apple??

  • Cherrie

    I have been having the same issues as the previous users (especially muting and hitting numbers. It is not only annoying but, since the screen is lit up, the phone becomes very hot on the face. When I tried hitting the home button to lock the phone it ended the call. The only temporary fix that I have found so far is to open up my flashlight app and just turn the light off. With the app up I cannot hit any buttons but this does not fix the heat issue.

  • Threem

    Wow, after looking for a thread like this and reading every single comment I’m thinking if changing my iPhone 4…

    If I’m not wrong, to have the phone screen turn black in call ur ear have to cover the speaker part located on top of ur screen. And please don’t be racist… I’m a Chinese and I sweat too ok!!! I’m from Singapore and the issue I face is ehh after a call ur sweat gets to be on the screen and when u ever tried to tap a button on the screen it doesn’t work or sometimes it will not be accurate as the screen uses “heat sensor” or something similar to that therefore, when button its pressed it doesn’t recognised unless u forcefully press it…

    I’m thinking of switching to Blackberry and get an iPad2 with 3G instead of having such problems..

  • Mo

    When the other person on the line keeps saying “hello? hello?” then I know the stupid mute is on again. This smart phone is so damn stupid!!! Of course Apple can ignore these issues cuz people are still buy loads of their products regardless!!! Somebody should just spread these voices to all over the world like crazy to let them know they’re not the only one.. there are probably more people who are experience the same issues under the radar!!

  • Ang

    I had the same problems…hitting the mute button, facetime, end button, dialing a number while talking..anyway, I tried the “re-set all settings”
    ( settings-general-reset- reset all settings) worked perfectly…for now
    good luck

  • Kristen

    Mine is doing same thing for past month! I’ve had two replacements since I bought the iPhone last June for internal issues..definitely leaving apple when my contract is up! I can’t drive 2 hrs to an apple store every couple months for this!

  • Ryan

    My girlfriend bought a white iPhone 4 and had the same problem all of you are having. For some reason, the screen protector is the main issue. I saw a black strip, just above the ear speaker and assumed it was the sensor that was covered by the scree protector and tried covering up with my finger and the screen does not black out. The best analogy I came up with is if you use a highlighter to highlight a word on a piece of paper and tried to make copies of it, you would lose the word or partially lose the word that was highlighted. The original copy, you could see the highlighted word but copy machines cannot duplicate that effort. So, with that in mind, I peeled the top screen protector back a little and cut out a small section where the sensor was and put the protector back on. Needless to say, it worked! Called my phone and covered up the sensor and the screen blacked out, never again accidentally hitting the buttons! All you need is scissors!

    • kt

      Yes, this solution worked for me. I think you are right!

    • robyn

      Mine was doing the same thing. I have a otter box on mine. I took it off and the phone works perfect. I am thinking it is a case or screen protector issue rather than a apple issue. If you take a black sharpie and black out the inside of your case up by the ear part it will work like a charm. Kinda strange but I think the cases are reflecting light on the sensor somehow. They need to make the inside of the cases black to work properly. Just a thought! Try it and let me know if it works for you.

  • Traci

    Ryan,
    YOU ARE A GENIUS!!!! it worked!!! Verizon was actually sending me a new phone today because we were thinking it was a software issue….thank you thank you!!!

  • Brad

    Same issue. But from a fix standpoint here’s an idea for Apple. How about this stupid sensor thing, you use the sensors in the phone to note when to turn the screen off during a call.

    99.5% of the time when you are talking, the phone is in a vertical position even when you are laying down. When you are looking at phone and needing to access the buttons, the screen is horizontal. Many Iphone games use this feature why can’t apple themselves do it? Why not lock the phone in the vertical mode and unlock it in the horizontal? You don’t need a face sensor of any sort.

    Durr. Maybe I should go get a job at Apple…

  • Sue

    I have been driven mad by the same problem, i am on my 4th i phone 4 in 8 weeks, on a business contract and losing lots of businesss with cutting off calls and eventually the people get fed up with not being able to talk to you. I have been to o2 twice with a phone replacment and apple store twice, have been given lots of reasons why but none of it has worked, wish I had never changed from the i phone 3. I will try the reset idea and hopefully will work, if not it might have to be a blackberry. Apple you need to get this sorted otherwise you will lose alot of customers to your competitors

  • Rosilyn

    Im constantly putting my boyfriend on hold!!

  • jeanna ku

    So i just bought an iphone 4 and have never owned one before. I thought after talking to friends that I was just holding the phone wrong and will just get used to hitting the buttons every two seconds. If you reset your settings, it will fix the problem. I read it on this forum and if it did not work, it would have gone back today. The screen now blacks out, it should when using it. Thanks to whoever figured that out, I now love my phone.

  • FuegoMCS

    Tried the “Reset All Settings” option on my new white iPhone 4 without any luck. Then based on what I’ve read here and other forums I lifted my Zagg screen protector and trimmed off part above the earpiece speaker that covered the proximity sensor. PROBLEM SOLVED!!

    • FuegoMCS

      This also worked on my wife’s phone and those of two friends. So it would seem that the screen protector manufacturers need to modify their products so as not to cover the sensor.

  • Sue

    thanks for the reset infor this has worked for my phone, great hopefully should be ok now

  • Jessica

    Resetting all settings works. And it doesn’t erase your stuff

  • Heather

    I was having the same problem and was freaking out! If you have any kind of screen protector you need to make a hole for the light senser and if you have an otterbox case you just need to pop out the plastic piece that covers the light senser and the camera….Instant fix!

  • George

    Thanks to all of you! This has been driving me crazy and I’m on the second phone. I finally found your comments and today I decide to try it all-cut the screen protector, took out the plastic piece on the Otter Box, blacked out the ear hole as well (actually I only had red Sharpe but that little bit of red looks great with a black and white Otter Box case) and it finally went black when I made a call. YOU GUYS ROCK!

  • Ishanmandani

    Same here

  • Dfinklea7919

    I am having the same problems.  It worked fine for 3 months & now it keeps turning on speaker & face time.

  • C_kelly86

    i am having the same problem! it worked fine the first month i had it but now it keeps pressing buttons and turning on mute, speaker phone, and face time when i am in the middle of a conversation. help!!

  • Twotonrat

    Me to same problem any help?

  • Flower_angel_me

    I have the same problem. How can you lock the screen when you are in a call so this doesn’t happen?

  • kbirdy

    I had the same problem.  Solution:  hit “settings” button; then hit “general”; then hit “Auto-Lock” and change 1 minutes to 2 minutes.  I don’t know why, but it lessons the screen sensitivity.  Happy iphoning!

  • Runningbasketband

    Yup have this problem and even have a screen protector and the whole phone is in a griffin cas

  • Simeendarouian

    I have the same problem. Drives me nuts! It’s one thing to do this while on the phone with a friend, but it’s embarrassing when you do it while talking to a client for business purposes! I miss my Droid Incredible

  • Debord78

    This is making me crazy!!  I hang up on people, push the facetime button, mute people…the worst was when I was talking to my sister, unknowingly dialed my husband and then my gynocologist!!!  Had them all on a conference call.  Really??????

  • Alyssa_maier2

    My iPhone four I have only had for a few days
    Me and my boyfriend talk a lot on the phone but it seems literally every call I have I end up rambling to myself and hearing silence, I get upset thinking I’m being ignored only to look at my phone and see my ear hit the hold button or I hear him keep saying hello and I realize it’s muted. This sucks because Im totally turned off by using speaker phone and I feel like an idiot holding it away from my face, so now I’ve tried to use the headphones with built in mic but I keep thinking I’m talking too loud. This sucks.

  • Aaron

    Me, too. I got the new iPhone 4 last night, replacing my iPhone 3 which I loved. My problem is my ear keeps on hitting numbers and making loud dialing noises, hangs up on people, and does pretty much everything that all have complained about. I am VERY disappointed, I got this so I’d have a higher Mpixel camera and the video feature for my daughter’s wedding. I’m sick of apologizing to people for calling them by accident!!!

    Am trying the reset, but after reading the comments, I’m quite sure it won’t work permanently. ;o(

  • http://www.personalitypower.com Fred

    I fixed mine and helped several others to fix theres. It was our cases! For the sensor to know you have the phone to your ear it must be able to tell a change occured. The cases we had prevented the sensor from knowing if we had our ear near the phone. Test for this type problem by calling someone and then holding the phone to your ear. If the phone goes black, it is not your issue. If the phone does not go black and you have a case on it the case is probably preventing the sensor from working correctly. I removed a peace of clear plastic from my case that protected the sensor and now the problem is gone. Another person opened up the sensor area and now they don’t have the problem Before we cut our cases we tried calling without the case. When we held it to our ear the window went black. Hope this works for you.

  • Pecosita

    THANK YOU!! my friend and i had been trying to figure out what was wrong with her phone because i have a black iPhone and he has the white one, we both have the same type of otter box and she had the problem but i didn’t so we color the piece in with a sharpie and it still didnt work, but as soon as we tried it without the piece it was fixed !!! We really appreciate the advise :)

  • Desiree

    I’ve had it hang up, add another call, muted all in one call. Can’t seem to talk now without having to set it on speaker phone.

  • karon

    Love the phone hate that it does this. How can we fix it???

  • Dayon

    Like everyone here ive recently upgraded to the iphone 4, i was going to wait for the new iphone ,now i wish i did. I was having the same problem with calling muting hanging up so on… how shite is that.

    removed the cover and yes it worked but thats not the point we buy these phones so we should be able to protect them too from damages and scratches, but it seeems we can`t because it covers the sensor so stops the phone working correctly.

    with all the money Apple have and how long it takes for the phone to come out and the cost of them , you would think they would get it right. love the phone but tech side bit shite.

  • steve

    i cant make it through a phone call without hitting the mute button and getting hung up on

  • Bre

    This is a known issue going all the way back to the 3G and remains lovingly adhered to by Apple, who have chosen to simply ignore user complaints. It is the main reason my 3G/3Gs/4G all sit in a drawer gathering dust. I kept getting promised that each new generation of phones would solve this problem but that was unfortunately, a series of misrepresentations by sales reps. As I read other forums, this problem is not unique to iphones, and seems to affect too many touchscreen smartphones. Something in the telometry sensor, I suspect, a defect carried forward through each model iteration.

    i never used a case and had the same problems.

    I can no longer make a single phone call without accidentally face-timing, muting, or hanging up. If this continues I will switch to a different phone, even though I have had the iphone since it came out.

  • ali

    Yes, got rid of another brand for this same reason (was in a safe case too though). Had a previous Iphone not in a secure case and dropped it, had it fixed and gave to daughter and she has in a case and has not got the same problems I have with the new iphone 4. The newer versions must be more sensitive than the old version, there should therefore be a fix Apple…….

    Yep, I now have the same CONSTANT AND PERSISTENT problem. For the last 2-3 days, I cannot speak to anyone for even 3 mins without “pressing” speakerphone, mute, bringing up keypad and dialing a bunch of numbers, and going into contacts.

    This problem actually appeared out of nowhere in the last 2-3 days. It appears that I am not even the one pressing these buttons with my cheek/face, because I am specifically holding the phone very lightly to my ear. Yet, these buttons somehow get pressed. It’s very annoying and I will be calling Apple store tomorrow.

    I got a iphone 4 for christmas that I haven’t opened yet. I was going to get the iphone 4s but the battery on it sucks. Anyway I can’t wait to get my iphone. This is the first iPhone I’ve ever had. I mean I have the 4th generation ipod with facetime, but I hope I don’t experience the same problems you guys are. If so, I’ll take it back and get a 4s I guess. :D

  • Sushma

    THANK YOU SOOOOO MUCH!! Removing screen guard plastic cover really worked soooooooooooooooooooooo happppyyyy!! :D

  • Sha

    Sorry but the 4s does same thing!! I had the 3GS and just upgraded to 4 s!! I will go back to 3GS as everything above happens on this phone!!!! I knew I wasn’t going crazy and the 3GS screen locked!! Hate the 4gs for that!!! So the 3GS is missing a front camera? So what doesn’t have all the call issues !!!! 10 times in one call! My friend even said she hates my new phone go back to old one! So apparently they haven’t fixed it in either 4 version!!!!!!

    I had to buy a new cell (Nokia) and i deal with PC Mobile. they have bad customer service. I only have this problem when my boyfriend calls me from his dad’s landline (which is where he lives nnow) and every time it either mutes on and off, the phone line dies and then I have to call back. Its only with him thats so weird! I dont have a cover on it but I just bought one to protect it when its in the cold. the company doesnt seem to care- i called like 4 times now…….i was thinkijg to wait to let it ring longer ad then answer it- would that help guys??

    Expecting a huge recall of the Iph4s is the rumors in the wind, take cases off phones, causing issue with proximity signal and reception, as of now the Iph4s cant be encased. Works much better without one, you will find.

  • Jordan

    Cant even breath on the thing without it dropping a call or calling someplace you dont want, kind of sensitive, take case off and you will be surprised on improvement, dont drop it, hope Apple makes improvements with any future generations, this is a defect of the Iph4. Dont encase it and it should be fine, unless you drop it.

      +1 on the Q-tip solution. I used my phone for months in an Otterbox case with no problem. When it started “face dialing.” I found this thread. Checked the opening that covers the sensor and it was full of dust. Qtipped it clean…problem solved.

  • Elise MEL

    Thank God for Google is all i can say… I thought i got a dodgy iPhone4s my screen was going on and off and was all over the shop… took it out of my Forever New case (which is sad cause i love my funky purse case for my phone) and perfect when my phone is down i can see the screen and when it is at my ear it is off!!!! :-) But now i need a new case for my phone heheheheh

  • MichaelH

    Thanks so much my wife was having the same issue, cut out a small part of the screen protector that was on top of the sensor and now her phone is fully functional!! Thanks so much!

  • mom2bryan

    My screen protector had come partially off. I removed it and the case I had on and so far it seems to have fixed the issue! I’ll get a new Zagg protector that will stick to the phone and see if it still works….THANK YOU! This has been driving me CRAZY!

  • Sifax Safir GA

    Add me to that list same problem. I am here because I am looking for fix for it.
    Yah Apple monopoly expensive crap/expensive data and call plans, 2 years contract…waw poor citizens they can’t afford it.
    They cant afford a phone that you can use withot contract without plans without having to unlock and jailbreak.Yah I know three guys they have same sensor problem many they dont pay attention to it…
