Black line in the middle of the screen, what's the problem?

Question

Iron

A week on the phone and this is such garbage, after the screen is completely turned off and after a while it reappears, first this line moves down a few pixels and then turns black. The problem is the screen, since this line is not on the screenshots.

Answer 1

Matrix defect. If there are no signs of a fall and liquid ingress under warranty, then go to the Gar.service. If there are sins, then use until it spreads wider and change for a fee. Good luck.

Answer 2

I am not an expert, but I will assume that the matrix has a beard.
