No outgoing audio over T-mobile after a week or so
I have a OnePlus 8 with T-Mobile. Every once in a while people can’t hear me on the call. The only fix that seems to work, is rebooting the phone. Than it’s fine for a while but after a week or so the problem re-occurs. It’s only happening with T-Mobile calls. WhatsApp calls are always working, WIFI calling is enabled but I have no way of telling whether the call is going through WIFI or cell. Anyone has an idea what’s happening here and how to fix it?
