Every time I change it in wallpaper and style, it changes back. I've repeated over again with no success. I deleted the actual video in my videos files. However the video keeps showing up. Does anyone have an legitimate answer.
How did you put it on your phone? You could have used Good Lock Labs, or Samsung Highlights, Theme Park or Home Up, or Wonderland. That's probably why it keeps returning, it's from one of the other apps not the Samsung Display app.
