I may have junped a gun with the workaround. It works (I see the caller ID) if I disable “4G Calling” option, however, I am now at times not reachable and I can’t initiate a call at those times either. Restarting the phone doesn’t help. Enabling “4G Calling” solves the issue right away (always), but then I don’t see the Caller IDs on incoming calls, again.
So now I can either receive calls reliably, but not know who was calling (and if I don’t pick up then I don’t know who to call back), or I can see the Caller ID but maybe won’t receive any calls, without any indication of this situation.
Thus is very frustrating… I don’t mind if some apps don’t work, but the calls must work reliably for me.
My operator is Hot.si (Slovenia) if it matters. Does anyone have a suggestion on how to solve this? If I don’t find it, I will be forced to change the phone (and OS), as I can’t afford to not be reachable, but I would really really hate to do that.
