It might be weird but...

...I have to say it. When I'm watching random videos, an image appears in the bottom half of the screen. If I tap and hold, I continue watching the video in full screen. This is probably a bug, but I was startled. The photo showed a wall, was same wall color, and the plasterboard were just like the ones in my house -same old looking-, but the wall my wall is very rough.

First of all, is this a coincidence? Secondly, do you also have this type of screen error?
