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...
