My wallpaper (usually photo of choice) has been scrolling a bit when I flick through my home screens. I didn't mind this. Today, out of nowhere (literally within the last hour or so) since changing my wallpaper pic, it's stopped scrolling and instead I can only describe it as 'twitching' left-to-right (or vice versa) when I unlock the phone or return from an app or other function to the home-screen. It also does it by itself in the time before the screen goes to sleep. There is no longer any scrolling (which I would really rather have, over this current problem) and nothing seems to be stopping the 'twitching' happening, not even changing my wallpaper pic back to the one I had before. It also does it with stock wallpapers as I've already checked. I've rebooted the phone twice and that hasn't solved it. I haven't had any updates today that I'm aware of. I really don't relish having to do a hard reset.
