why would my s5 keep changing the wallpaper it does this numerous times a day

[AC Question]

I go into settings/wallpaper pick which photo I want to display, hit set as wallpaper. Then within 10 minutes or up to an hour or more it will change to some other random picture.

Welcome to the forums. Have you tried a reboot? Or clearing the cache in Settings>Storage>click the cache partition?
