Muffled Sound On Phone Calls
I have noted muffled sounds on my telephone calls. This includes via the ear speaker, on speakerphone, and using bluetooth headphones. If I try to play a song, the audio is perfect which means the speaker on the bottom is fine.
Here are the interventions I have attempted thus far with no resolution:
- installed the most recent iOS 14.2
- rebooted the phone
- turned airplane mode on and off
- turned bluetooth on an off
- reset network settings
- assured that the cellular signal was fine
- enabled wi-fi calling
- I have cleaned the phone thoroughly
- case has been removed
- calls muffled with earbuds but music is flawless
- it also occurs while using FaceTime.
Can someone please help?
Thanks.
