Lock Screen Wallpaper Location The Galaxy S4 comes with a TripAdvisor lock screen wallpaper that rotates images every X hours of places around the world. Every now and then it has really cool ones that I would potentially like to save to use as my lock screen permanently, but I can't figure out where in the filesystem they are stored.

I have found a couple of posts saying it is located in /data/data/com.android.settings/ or something like that, but my /data folder is empty.

tl;dr: Where does android save the current lock screen image?
That depends on your Android version, but only changes a little. Wherever it is, you need root-access to retrieve it.

For Android 6 and under:

/data/system/users/0/lock_wallpaper


While primary (mainscreen) wallpaper is available at /data/system/users/0/wallpaper.

For Android 7+, the file name has changed to wallpaper_lock and is still available at the same place. You may want to fetch wallpaper_lock_orig instead, however.
