iPhone 11 microphone cutting out
I've seen other users with this question. This started happening about a month ago, I don't recall which iOS update it was. When I'm on a call or Facetime, periodically the other person can't hear me, as if my signal is bad when actually it's strong. I can hear them fine--it's just cutting out. I wonder if the problem is the noise cancellation.
I have tried the link sent previously to test microphones (https://support.apple.com/en-gb/HT203792). The mic itself works fine. Recordings are fine. The problem is during phone calls. Should I shut off noise cancellation? It happens when I'm on speakerphone and when I have the phone to my ear.
iPhone 11, iOS 13
