iPhone 12 Max Pro Microphone not working
I have a 4 day old iPhone 12 max pro, when using face time or messenger video call the microphone will not work, as in the person your calling has no sound . If I plug in my headphones then they can here me . Also when I record a video the microphone works fine . Just not on any video chats . I’ve updated the phone to 14.3 . Also reset the phone and removed the messenger app and re installed it . Still no joy .. is it an app issues or a phone issue ? Please help
iPhone 12 Pro Max, iOS 14
