It really does sound like there's something interfering with your proximity sensor or that it's malfuctioning. Try this: make a call. Then while on the call hold your hand ofer the top third of the front of the phone. Does the screen go dark? If it doesn't, remove any case or screen protector. Try again. If it works, get a different case. If it doesn't, take your phone in for servicing.
Note: The proximity sensor only darkens the screen while you are on a call.

Thank you that worked. Had old protective film that was interfearing, it's in the trash now.
