FaceTime mic working, video call not working.


My phone has a strange problem. When I video call with FaceTime, the other side can hear me. When I use another app like Whatsapp or Messenger, and I call with video, the other side can't hear me. The mic is not working.

What could be the problem?

Gekozen oplossing

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. 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.

Thanks for your answer. But why does it work with Facetime and not with Messenger or Whatsapp?


Those apps may be using a different microphone. Test all three, as detailed above to see if any microphones are failing. If they are good, try deleting the apps and re-installing them.
