My Z2's goes black while calling. When I took the diaganostics the proximity sensor is always ON. never turn off. What should I do ?
If you have a screen protector installed that's partially or completely covering the proximity sensor, then you'll have to remove it.
yes the same problem exists in safe mode too. Recently i had Re installed the Stock Rom which i got from XDA
So no screen protector installed? Try to perform a software repair using PC Companion using PC Companion then.
