So I just got a new battery for my S7 and all the sudden my boyfriend says there's an echo for him when he is on the phone with me. I don't hear anything but he says it's bad for him. As far as I know we don't have any weird settings on.
- Calling in Safe mode did nothing
- turning on speaker on either of our ends did nothing
- I tried turning on and off concert hall (didn't work)
We both have s7's
I think we've had this before but I'm not sure. Usually if I call someone else they don't have issues.
