I registered just to tell everyone to please avoid installing it. Maybe it still on BETA so not everything works perfectly.
What happened on my iPhone was that the touchscreen function works only in springboard. This means that when I execute any application, the screen starts to freeze and you cannot tap anything. All you can do is to hit home button.
When you hit the lock button, the screen does not turn off, instead, it just goes to dim mode. I TRIED restarting it for SEVERAL times but nothing changes.
My last choice was to just restore it and start from scratch.
But, it happened that I fixed the damn thing! What I did was: when you 'slide to unlock' it, I tapped the calendar*(you can see this when you checked it on the Kate app,not the built-in app) several times and give it a few seconds (the screen returned back to locked mode). I repeated this step for about two times. After that, EUREKA! The touch functions returned to normal. I unchecked all the add-on features of Kate and uninstall it.
This is only based from my experience.
Hope all of you can fix it.
