Chosen Solution
I recently got a repair on my phone and after it was continuing to function normally. A couple months after I received a black fade at the top right corner. Then when I attempted unlocking my phone it wouldn’t cooperate. I’d have to press my power button locking it continuously until my phone cooperated. The problem has gotten worse. I’ve tried hard resetting it, factory resetting it, and resetting all the settings.
More than likely you have a failing screen. If the company who repaired your phone has a decent warranty (6 months or a year) then should be able to get it replaced for free as long as there is no damage to the screen. If that is not the case, youll have to get it repaired again. There are instances where board level issues can cause the behaviors that you have, but more than likely it’s the screen that’s failing.
