Can't make gallery photos lock screen wallpaper (Samsung S3) I can only make the preinstalled wallpapers the wallpaper for my lock screen. I can choose an image from my photo gallery, select and crop it and then save it, but the lock screen just stays the same. Anyone know how to fix this?
I have a Samsung Galaxy S4, but see if you can set a common wallpaper through a similar path: Settings &gt; My device &gt; Display &gt; Wallpaper &gt; Home and lock screens.

UPDATE 2013-12-06: Another solution you could try is to clear the default app for pictures. If it's a 3rd-party app like QuickPic, go to your phone's Application manager (via Settings), select the 3rd-party app, and do a Clear defaults.

Afterwards, open the Gallery app (not a 3rd-party app like QuickPic), pick a photo, left-soft-click to open a menu, and click Set as. You can pick either: Home screen, Lock screen, or Home and lock screens. Source.
