Hey everyone.. A strange behavior of my international S3 (not rooted) : every once in a while when I swipe a contact to initiate a phone call, when I take the phone off my ear, the screen stays black and I cannot do anything till the other party hangs up.

For instance, if I want to hang up the phone, I can't do it cause screen is black and it won't turn on not even if I press the home button or the on/off button.

The only thing that makes screen responsive is if the other party hangs up. So that means a restart a day for my phone.. Anyone encountered this problem before?

 

It seems my proximity sensor was acting weird, since at times my screen wouldn't time out when I put the phone to my ear and sometimes it would turn off right after initiating a call, never giving me an option to end the call, or show the keypad or anything usable on the screen.

I took out the battery and now it seems to be working fine... But still, it's troubling me...
