Ok this is really irritating me now. I try to install protectors on my 4S and I make sure the screen is 110% clear of lint, dust and crap. AS SOON AS I lay that protector on there is crap all between the protector and the screen!? How the hell can I install without this problem. I will soon leave the shields as they have to be physically invisible for them not to annoy me or make the phone look pants.
