I have a Galaxy S20 FE 5G and all incoming callers are hear an echo. If I call them, the echo is gone.
I have tried calls with speaker on, speaker off, wi-fi calling ON, wi-fi calling OFF, Mono Audo ON.
The only thing that worked (I just tested in once) was turning Wi-fi off completely. Unfortunately, in my area reception is spotty and I cannot rely on a signal.
