How to Change the Wallpaper on Your Nexus 7 Tablet
The Home screen on the Nexus 7 tablet has two types of backgrounds, or wallpapers: traditional and live. A live wallpaper is animated. A not-so-live (traditional) wallpaper can be any image, such as a picture stored in the Gallery app.
To set a new wallpaper for the Home screen, obey these steps:
Long-press any empty part of the Home screen.
The empty part doesn’t have a shortcut icon or widget floating on it.
Upon success, you see the Choose Wallpaper From menu.
Select a wallpaper type.
Three options are available:
Gallery: Choose a still image from the Gallery app.
Live Wallpapers: Choose an animated or interactive wallpaper from a list.
Wallpapers: Choose a wallpaper from a range of images preinstalled on the Nexus 7.
Choose the wallpaper you want from the list.
For the Gallery option, browse the albums to choose an image. Crop the image to select the portion you want included on the Home screen.
For certain live wallpapers, the Settings button may appear. The settings let you customize certain aspects of the interactive wallpaper.
Touch the OK or Set Wallpaper button to confirm your selection.
The new wallpaper takes over the Home screen.
Live wallpaper features some form of animation, which can often be interactive. Otherwise, the wallpaper image scrolls slightly as you swipe from one Home screen panel to another.
