My voice breaks up on iPhone 11 Pro calls — sometimes
On some calls but not all, the person I am speaking with will tell me I sound like I’m breaking up. When I remove my wired earphones and talk directly into the phone, my voice is clear.
I have had this in the past and know it can be caused by a dusty headphone jack. I have tried to clear out dust from the jack, but don’t see any.
This happens with two different earphones, one of which was brand new. So it’s not an earphone microphone problem.
My software is up to date. It doesn’t happen on every call. I will sometimes have long calls where my voice is clear. Then all of a sudden it becomes broken up.
Any suggestions for what to look at? The Apple phone support rep suggested I try removing the case. I have an OtterBox case so will see if removing it makes a difference.
iPhone 11 Pro, iOS 13
