In 1 month happened to me 2 times
Both when I was waking the phone up unlocking the screen using the hardware ''home'' pushbutton.
Pushing the power button turns off the screen and the next unlock the screen shows ok.
Both instance of the issue while running gl_notecore kernel (V6 and V9)
In the last 2 weeks i have not experimented the Issue with LRG cfroot kernel.
I suspect, in my case, the issue is due by gl_notecore undervolt/overclock.
