Ok I've been fighting this problem ever since the OG Droid. All I'm trying to do is find out how to set a wallpaper to the phones native resolution. Aka not have it span the extra screens. Currently when you go to set a wallpaper it comes up with a little outline of whatever and makes you crop it. This is what I'm trying to get around. I guess Google figures they want to have a wallpaper that matches the resolution when you take into consideration the extra screens you have. Well I have Nova Launcher and have scrollable wallpaper turned off. Why something SO simple hasn't been fixed all these years amazes me. Reminds of me Apple.... If anyone has ever had a phone other then Android, you know when you set the wallpaper whatever the native resolution of your screen is matches the size of the wallpaper.
