Wallpapers are images from Gallery (pictures you shot with Camera, synced from Picasa, and so on), still images included with the system, and live images (such as an animation or a map that centers on your location). They take the place of the default background for your Home screens.
- Touch & hold anywhere on a Home screen that's not occupied.
A list of options appears.
- Touch a wallpaper source:
Gallery. Choose from pictures that you've taken with Camera or downloaded to your device.
Live Wallpapers. Choose from a scrolling list of animated wallpapers.
Wallpapers. Choose from thumbnails of default images, or touch a thumbnail for a larger version.
You can download additional wallpapers on Google Play.
- To set a wallpaper, touch OK at the top of the screen (for Gallery images) or Set wallpaper.
