With my note 5 I downloaded a random image for a wallpaper and when I set it as a wallpaper it had a option to add motion effect. I can't find this on my 8
I am not using a Nova Launcher, however I am not able to see the Motion effect as an option when selecting gallery pictures as wallpaper.. is there a way to upload a picture into wallpapers app/settings to make it an "official" wallpaper to provide the Motion effect option ?
