full bugreport here: View attachment 2353994

this was created after flashing pureX4 and musicbox3 ota...

just the ota... musicbox3 full gives me a bootloop with the viperx version...

cool :)

does it happen for you too, that sometimes during a call when the display gets switched off your ear activates autobrightness with cm slider ???

seems for me, proximity sensor disables screen but not cm slider...

cheers
