Microphone not working on front facing and rear camera.

So I recently replaced my screen and when I powered back on there was no audio from front facing camera or rear facing in any application on my phone. If I open voice memos and hit record I do hear audio correctly but I’m guessing that’s because I’m using the third microphone at the bottom of the phone.

Any help or suggestions.

There are 3 microphones in the iPhone.

  • The bottom microphone is for Voice Memo and phone calls. The other microphones serve as error cancellation
  • The (top) front microphone is used for FaceTime calls, Siri and selfie videos with the front camera (FCAM). The top back microphone serves as error cancellation
  • The (top) back microphone is used for videos with the rear camera (RCAM). The top front microphone serves as error cancellation

Make sure you update your device to the latest version of iOS and then try to isolate which microphone is not working properly by trying each individual microphone with the related apps above. Check the microphone port holes for dust and debris which could be attenuating the sound.

If the issue affects more than one microphone, then it could be the Audio Codec IC on the logic board. Anything at the logic board level will require micro-soldering so you would need to find a repair shop that offers those services.

Hey, Thanks for the response. In the above I explained that I’ve tried voice memos and it works. The front facing and back facing cameras however do not work. They both worked fine before I changed the screen and I do not recall having any issues whilst replacing my screen that would’ve cause any damage to the logic board.

由完成的
