I have an issue with my iPhone 12. I can't hear anyone who calls me or I call unless I'm using headphones or the speaker. Anyone have any troubleshooting ideas?
@Tim_Eagon I had a similar problem with my 12 last fall. Other people could hear me very faintly. It turned out that the holes for the microphone were plugged with pocket lint.
@arathar The people I call can hear me, but I can't hear them. I did clean the receiver area though and it didn't help...
