Help Screen blackout during calls

[DavidJames2012]

I have a galaxy s3 and until recently it has been fine. But now when I make a call.... The only way to end the call is to do a battery pull.... When I'm on a call the screen goes blank if can still phone people but usually I move phone away from my ears and the screen comes on for me to use keypad end call etc.... Anyone able to help me out? Cos can't keep doing battery pulls. Thanks

Try a hard reset.

Do you use a screen protector/case? Something could be tricking your proximity sensor. Or you could possibly have a bad proximity sensor. Every Samsung phone I've owned has had prox issues.

Are you talking about when you put the phone in landscape? I have this happen when i put it in landscape, the phone will black out. If i put it into portrait it comes on and i can manuever within the phone.

Are you on any rooted roms by any chance? I don't know if i had this issue when i was stock.
