On my iPhone 7 I have these problems: None of the 3 microphones works. (Front camera, back camera, Siri, Memo). Internal Speaker doesn’t work, when trying to call somebody. Earbuds Speakers nor Microfone do not work. Music from Apple music can be played by external speaker, but not with earbuds. Call’s can be answered with blue tooth devices. Musik is ok with blue tooth devices. What can be wrong ? What is a possible fix? Thanks Lars W
It seems your iphone seven suffer from audio ic disease that require micro soldering repair. Other classical symptom are long boot time and no way to reccord audio with vouce recorder. It is (if you are affected) due to a weakness in iphone 7 design. Search for audio ic iphone 7 repair and you will find many video. this is not a diy repair !
