Something happened

Creator

with "destroying" I mean it freezing the app or phone. Crashing and bring me back to the Lockscreen. Something happened not the same as this but the phone suddenly went back to the Lookscreen and just put my wallpaper that i had once used as a wallpaper but deleted instantly. (This happened about 1 week ago, Wallpaper more than 6 months) it's all fine now I got my "changing Wallpaper" back.
