I am facing call drop and calling failed issues. I have even tried restore with latest firmware, also replaced my cellular sim to new one with 4G. But still i frequently face call drop issues while talking, and also when dialing it show up “calling failed” in middle of the call it gets disconnected.
What signal strength are you getting ? Are you connected to wifi? Could it just be poor service? Have you tried resetting your phone to factory defaults?
