We simply love wallpapers. They’re one of the first changes we make to our Android devices and often represent our moods, interests, or wicked alter egos. They’re as unique as the individuals who use them and while some people pick one and stick with it, others change them more often than a teenager’s Facebook status. Each day we’re going to feature a free wallpaper for you to download and use on your Android device. Depending on your device, you may want to use your favorite photo editing software to resize the image for a better fit. Once that’s done, apply and enjoy. Your homescreen can thank us later. Cheers!
