When I'm on the phone and talk for over 15 mins or so my screen won't come back on. It goes off when I put it against my head like it is supposed to and comes back on when I pull it away like it should. But after 15 mins or so it goes off and wont come back on when I pull it away. So I can't end my call and when it's time to end the call of course I can't, nor can I get a call waiting. I had my phone's display set to time out after 10 mins then changed that to never time out but it still does this. However this setting shouldn't matter I wouldn't think, but it doesn't help either way. I'm having to do a battery pull to get my screen back, I have no other issues other than this. I hope I don't have to take it back! Will this be fixed on the December update? I plan on putting a call into Verizon tech support later but wanted to get your thoughts. Any ideas?
