Microphone static noise and hard for people to hear me during calls

I've got an Iphone 7 Plus with a weird issue. When making phone calls, people complain that it is very hard to hear what I am saying. Both me and the person at the other end can hear static noises . If I record something, the same problem appears. As soon as I use headphones, the problems are gone.

I have changed the charging port / microphone assembly twice now so I suspect that it could be something else that is wrong...

Any ideas?

There are several microphones on the iphone and when a microphone isn't directly used, then it is used for noise-cancellation. There are 4 microphones in the iPhone 7 Plus (two on the bottom).

  • 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.
