Screen imprint on galaxy 5s,accident

[Candy Oliver]

Newb, when trying to become familiar with new phone, I inadvertently caused a screen image on the phone that was the exact replica of whatever image is from any website I view. Would not remove no matter what I triedaccessory option on phone did not work so I tried the developer option and found I had the wrong check mark on sizing so I guess said none so now is gone Thanks
