Suddenly lost cell service
I've had this phone since new, used it for about two years, when suddenly overnight I lost all cell service. I was working fine when I plugged it in but when I woke up, it showed no bars and the signal strength says "0". I switched to my spare phone and pulled the back off(after the signal issue) as the battery was getting poor on this phone, but I would like it as a spare. Where does one start about the signal issue?
Wifi calling does work.
In service mode menu it does say: ASM MIPI DEVICE FAIL
