My calls are constantly breaking up. My signal bars drop without movement by me or the phone. I can hold it steady and see it go from 3 to 2 bars. The people I talk to say it keeps breaking up even when the bars stay constant at 2 or 3.
I have no problems hearing them.
I turned off my wifi and tried just using the LTE network. It seems like it might have made a slight difference, but it still breaks up. Different locations in my house and outside don't make any difference.
The above link about the microphones doesn't seem to apply. I took the case off and there is no debris underneath. My phone is 5 months old. I have iOS 14.2 installed. My carrier is ATT. Is this an issue with the 11?
