Ipad pro 11" 3rd Gen microphone stop working on any call/video call app
I am having exactly the same issue in the below discussion.
https://discussions.apple.com/thread/251645930?answerId=254456773022#254456773022
The microphone work in the voice memo, camera rear, and front, but when entering the call application such as facetime, telegram, messenger, and other call apps, the microphone stopped working.
On telegram call the other partner sees that you muted the microphone while the microphone was not muted at all.
I had been to apple store one to fix this issue. They didn't tell me what is wrong with my iPad pro 11 3rd Gen that I just bought for 3 months. They just replace it right away for me. But right now, after 3 months with new replacements, the issue happened again.
