Hello guys My girlfriend's iphone is screwed up, she can't be heard during a call and she can't hear the person calling, I did everything I could think of, reset network settings, turned LTE off, restored, hard reset... She bought the iphone 5 on release day back in 2012, she has no warranty left, we're 2 hours away from the nearest apple store, the phone was working fine a week ago, she didn't drop it or anything, it's not water damaged. The phone speaker is working fine, so is the microphone. It only stops working during calls. Facetime calls work perfectly. The phone has always been in a case. Thank you!
