I have had a green stripe on the edge of the display for a few days from the bottom right edge to the top left corner. If I change the brightness from as dark as possible to very bright, it is gone. Now the question arises how I can't see him even with dark brightness. I would appreciate any helpful answer.

I have the Huawei Mate 20 pro

Did you drop the cell phone? Maybe just a broken display?

No, that's not why I'm surprised
