Wifi calling S21 Ultra

[Claired28]

I use WiFi calling but for the past month when making and receiving calls the call starts off perfect then minutes into the call it goes really bad quality like I'm in a bad signal area. Does anyone know how to fix this. Re started phone several times turned wifi calling off and on...nothing, still the same. So now when I'm at home to make a call I have to turn wifi calling off and use normal signal.

Wiping your cache partition should sort the issue

I use usb headphones to do nine but you can also plug charger cable into a pc/laptop or charger cable between phone and tablet

If you go into call settings - WiFi calling and set priority to WiFi then this should help.
