i removed the WallpaperPicker as i thought its not neccessary. From then i am no more able to change the lock screen wallpaper different from the homescreen wallpaper.
So i need the original file to get back the function. May it will be possible that a user here uploads that apk which has to be from the stock Z2 FW 17.1.a.2.55 or if that is not allowed may tell me a source where to get it.
Thanks in advance
