Do you happen to be running a modded kernel?
Reason I ask is that on the TMO specific build if the kernel was modded in any way it broke WiFi calling. I am trying to figure out if the same is true on the Android M preview.
My specific issue is that I can't change the DPI (or at least when I did it broke WiFi calling on TMO build). While not a deal breaker, it would be nice to be able to do it without borking WiFi calling.
Thanks.
