Using Nova launcher, it gives you the option of excluding the top status/notification bar and bottom menu bar (not sure of that official name) from wallpapers and such. Making wallpapers 1080x1920, though, the pictures creep into the top and bottom. I can't find anywhere the sizes of those two bars to subtract from the "official" wallpaper size of 1920 so it fits. 1080 would be the same I guess. Thanks for any help
