When I make or receive calls, quite often, people can not hear me. I can hear them just fine. This started happening a few months ago with my Samsung Galaxy S7. That phone was pushing 5 years old and was having other issues, such as charging and battery life, so I upgraded a week ago to the Galaxy S21 G5. I still have this happening! So I'm fairly convinced it is NOT the phone. I sometimes use Jabra Elite 75t ear buds. It happens with these as well as without.
I've also tried Wi-Fi calling and it happens when that is enabled as well.
I can call my self with Google Voice, both ways, and the audio seems fine.
I need help resolving this issue.
The S21 is brand new. Took it out of the box and set it up on Monday I think. There have been no instance of damage from water or other substances or impacts.
