Hey Guys,
I have a 6s iPhone. Its microphone works properly during video recording, sound recording but when I make a call it is unbelievable quiet. I tried to reset the phone in all possible ways, but nothing helped me. (nor disabling the Phone Noise Cancellation option) With iOS 11 I had the following experiences: the microphone was quiet, and while I moved my phone sometimes the microphone was totally mute. Then I updated to 12. Now I have a continuous record but it is soooo quiet, nobody can hear me. What is the source of it? Any solution?
