What a cool Android wallpaper it is, a dark 3D background with smooth white lights in the abstract. By using a resolution of 1080×2400 pixels, you can easily apply this wallpaper to your new smartphone. By the way, a picture with 1080×2400 pixels is also popular as a 20:9 aspect ratio. Recently, most of the new smartphones have a longer but smaller resolution. The advantage of these resolutions is that they allegedly can fit more content on one screen while browsing or reading.
