Just tried to change my lockscreen wallpaper and can't. I go into settings, lockscreen, wallpaper. Code the image from the gallery, set the area to use, hit save. I says it changed, but no, it hasn't. Tried clearing data for the stock launcher and gallery with no change. Does anyone know where the lockscreen wallpaper is saved? I found where the homescreen wallpaper is saved, but don't know where to look for the lockscreen.
