I'm running marshmallow on Samsung s6. Recently noticed that 2/3 of the screen is covered with a pink opaque overlay. It is static and appears atop everything.
I am unable to post a screen grab due to being a new user, but if anyone is interested in seeing it please let me know.
Also, there appear to be a few graphic icons in the top right hand corner of the pink overlay. These are are also opaque and are not interactive.
It's one of those issues - once noticed, you're can't unnotice it.
Any help with getting rid of this will be greatly appreciated!
