Strange Tint on Galaxy S5

[AC Question]

I own a Galaxy S5, at the bottom of my screen, there's a faint square with a circle in it, then there's a weird orange tint around most of my screen. I have no idea what it is, please help.

Dial *#0*# to get into service mode. You can test the screen there. If it fails, it's the screen. If it passes, it's software.
