Why won't this overlay picture go away?

[AC Question]

I have this image that is on top of every one of my apps it has a VERY low opacity, but still shows and is whiteish/pink. it stays in one spot too, It says on the bottom "Tap to Explore" and in the middle it says "Galaxy Note 4" and some other picture in the background.
