How can I test the Proximity sensor in an Iphone SE?
My husbands Iphone SE appears to have a proximity sensor that doesn't work, but I can't tell for sure, When I talk with him on the phone his ear is constantly hitting keys and trying to dial numbers. What can I do to test if the proximity sensor is bad and/or get it fixed?
