I love to use a unique background for my smartphone. Such as this colorful 3D object. This background was specially designed for any smartphone with a 5-inch up to 5.5-inch screen size. One of the best smartphones suitable for this background is Oppo A77, a smartphone with a 5.5-inch screen size. This Oppo wallpaper can be an alternative wallpaper and screensaver for Oppo A77. So, just download and save this file in its original size and you will get this image in 1080×1920 pixels.
