I've having really bad connect issues with my S21 ultra - and its only just really started to happen.
Typically when a call connect the first time call quality is ***** and the drops out. Otherwise it doesn't connect at all first time and I have to redial to get it to connect.
Incoming calls often don't even ring going straight to message bank even though I'm not on the phone. I've dont at least 3 restarts now and its not making any difference at all. Can any one help? Its getting beyond a joke now
SMS's also take ages to send and often fail and need to be resent. Any help would be greatly appreciated.
