The easiest way to change things up on your homescreen is to add a new wallpaper. Of course you could scour the web looking for a great image, then edit it to fit your screen. You could also grab one of the newest wallpaper apps around "Zyden". Zyden has been updated to include the material design. The wallpapers are all stored in the cloud so they won't take up memory space on your device. Only download and use the walls you need. The app is pretty minimal and is far from cluttered. Main categories include 3D, Dark, EarthView, Googlish, Material Design, Photography, Photography Remix, and Simple. Head to the link below to grab this wall app.
