This problem has been an issue for since the update a long time ago. I am finally really annoyed that I cannot figure it out. Whenever I call someone, the screen turns off. Ok, no big deal right? Then when I want to use the dial pad or end the call, I can't because the screen wont turn on. The power button does not do anything. I have to take the battery out so that whoever I call does not have a ridiculously long voice message or they hang up and the screen turns back on. I tried to find a way to make it work but nothing. I noticed that some of the features from the previous version are not in the current update like the pocket detection (which I had used). Anyone got any ideas? Thanks
