I've been having intermittent 1-way audio problems for the last several months. (I can't hear the other person but they can hear me.) I am *not* using WIFI calling.
There were times when it would happen multiple times in a day. Then it totally went away. Now it's happening again, but less frequent -- probably 1x-2x/week instead of multiple times per day.
It happens from multiple locations.
My device is an LG G4 Marshmallow, standard T-Mobile firmware. (ie, No custom ROMs)
I have tried with VOLTE both on and off...it seems to happen either way, although it seems to be less frequent when VOLTE is turned on. Of course, the issue being intermittent in nature, it is difficult to be sure that VOLTE on/off is having an impact.
Is anyone else having this problem or have suggestions for resolving?
T-mobile is sending me a replacement device. I have mixed feelings on the odds of that helping, but will try it out.
Thanks!
Marc
