Those Chromecast walls are so awesome I have actually found myself just truning on the chromecast and leaving it idle glancing over at the big screen as the image changes. If you are growing tired of your phone's stock wallpapers you might want to grab the Chromecast wallpaper app. The "Chromecast Wallpaper App" for Android by developer "donniemceduns" brings these super high quality wallpapers to any other device. This brings you 680 stock wallpapers from the Chromecast. I bet you didn't realize there were that many! Each of these wallpapers are 1920x1080 so they should fit those 1080p screens on your phones just perfectly. This app is totally free in the Play Store.
