The nokia 8.1 display is always blinking
are you sure it's not winking at you?
I have the quite similar issue. My Nokia 8.1 was suddenly lost its display as in COMPLETELY even a little brightness. It is just happened without doing anything to my phone. I thought it was a hardware issue that seems the LCD are broken or got disconnected but then I found a way to restart my phone using adb command and then I found it is just a Software issue. Hopefully the Nokia team notice this issue and will fix the said issue in the future updates.
