When calling from home, we sometimes get poor (unacceptable) quality. We can see the phone is using cell signal when this happens, although the WIFI signal is strong. Cell signal is poor at our location.
Wifi analizer shows -50dB on 2.4GHz channel 6. There are no competing signals, as we live in remote area.
5G is -70dB, but we removed 5G password from phone in attempt to solve this problem
