Why does the application that you have been using for a long time shine through on the screen of a samsung (android) smartphone?

Question

Android

And how to turn it off? That is, if someone does not understand: On the desktop (and not only on the desktop) you can see (in a transparent form) the application menu that you have been using for a long time. I noticed this thing already on the second android smartphone, because I think that many have come across this and solved such a problem.

Answer 1

Perhaps the screen burns out?
