Hey, I've only got my new phone for 3 months now and since about 1 month I have a problem when calling. When I make a call the screen goes black and I can't unlock the screen anymore and it only works again once the other person hangs up the phone, I can't even do that myself. And when I get a call the screen always unlocks when I place it near my ear so I always end up pressing something on the screen. Help is appreciated thanks!
