I have a Samsung Galaxy J7 V2 that was new back in 12/2018.
I can not answer some calls and some can be answered
When I get a call that can not be answered it just rings on the callers end without going to voice mail. On my end when I try to answer it the answer screen opens but no caller is there. I am also not able to turn on the speaker, mute, or keypad. The timer is operating until I hit the call disconnect.
I have removed and cleaned the sim card, and reset the phone, but haven't done a hard reset. I called Verizon customer support a couple of weeks ago and they reprogramed it in Verizons system and it worked for a few days but now it is back to doing the same thing.
I have the HD voice and video turned on.
Once again this does not happen to all the calls or at certain times during the day or night. It happens randomlly during the day. One call I can answer then the next I can't.
