iphone 12 pro max no sound on phone calls
Sometimes when making or receiving calls there is no sound - it rings but no sound on pickup. Sounds as if both parties on mute, neither can hear any sound at all. Talked to apple support before and went through the whole troubleshooting process, eventually backed up and reinstalled everything from scratch. That seemed to solve the problem but it didn't last. Sometimes have to call 4-5 times to get through, not dependent on reception.
