On occasions, the wall paper for my home screen changes without me doing it. I am not sure of the reason why it happens as I am not aware of me doing anything to cause it. Is there a way in settings or an app that will lock it into place to prevent this from happening?
Sometimes older phones do that when they run out of RAM and restore the default home screen background.
just don't use cheap devices or low end devices it's system behavior to save resource tho Best Regards NST_Adventure
