When I first got this phone it hadn’t had this but for some reason it gradually started to appear. At different angles I can’t see it, at some I can and it’s pretty annoying. At first it was pretty small but now it takes up the top left of my screen (still sort of small)it’s triangular and some parts of it are lighter. At first I figured maybe a dent caused it but I’m honestly not sure.
If it has gradually appeared it will most likely be your screen. A new screen for the 7 is not that expensive.
