I have a bug with my S22 where when I make a call, I can't hear anything once the call is connected. It does connect as the call timer starts to count the nr of seconds connected but I can't hear anything, on normal phone ear speaker or on loudspeaker. Before this happens, the phone has been working fine for many days or weeks. The only thing that seems to fix it it is turning the phone off and on. I've tried switching off WiFi (thinking it may be a WiFi calling issue), switching off Bluetooth (in case connecting to some phantom device and playing sound through that), changing from 4g/5g connection to 3g, switching flight mode on and then off, checked the call volume is not muted. None of these work and restarting is the only option.
