I have a huge problem. My M1 note’s screen died, I think. Or something else. In the morning the screen starts to flash randomly. Previously I changed the screen because it’s broken. I think, OK, it’s my false, maybe something was wrong than. Phone off, cables out and in again - OK, the sreen is right. Screws back and I used the phone. But next time it’s still in black. It’ light up, but it’s black. I taken back the broken screen, but it’s black, but lightened, too. So, not the screen is wrong, but something else.
But what? Please HELP!
