Hi,
I repair phones. Oneplus most of all.
I changed a LOT of oneplus One screens. But almost always I have this problem.
With the new screen, sometimes it won't turn ON the screen after sleep or press power button. I hear that the phone is ON, but the screen is black.
I have to change random screen settings (double tap to turn on, or off, etc) until it works ok again. When it stays black, I have to reset the phone to get the screen on again.
Anyone else with this problem?
