Chosen Solution
My honor 8 started having screen issues today, but it feels like they are software more than hardware-based. When pressing the power/screenlock button the screen will flicker on for less than half a second (everything looks fine in this screen as far as I can tell) and then goes dark again. Pressing the lock button one more time doesn’t do anything, thus I guess this locks the screen again, but then after that further pressing the lock button repeats the above behavior.
I tried restarting the phone using the power button, power + volume up, power + volume down, power + both volume, but the result is always the same. Any ideas on what is happening here and what I could try to solve it? Should I just start looking for a new phone?
Your phone screen display may not be getting enough power, try charging the phone, if the screen stays on when charging but goes off when disconnected your battery may not be supplying enough power to the display. You may need to service it or replace it.
