Screen is stuck?

[AC Question]

Hey. This here is a little hard to explain, but yesterday I noticed that on my screen there is a transparent mark from snapchat . so when I go on a white screen i can see that it says snapchat up in the left corner. Any suggestions on how to fix?

Hi

My guess is that there is a setting, somewhere within Snap Chat settings, that will disable this.
