mobile

I've tried all the 5.1 ROMs and seem to have the same issue with every one. I set up the phone, make backups etc and all works smoothly.
Then for no reason I'm getting random reboot. When the phone wakes there is no lock screen, just my notification bar and a black screen. Pulldown shows notifications, buttons etc. Power button shows reboot menu etc but the rest of the screen is black with no function.

I tried to narrow it down by trying different agni settings, running stock kernels, now trying different launcher as its always been on Nova.

There is no pattern to when it will go so getting a logcat isn't easy.

Any help or pointers, or anyone else had the same issue and fixed it.
