The back cover of the Honor Y9 Prime is supposed to be strong for protection purposes and designed in a manner not to lose style. Most of them are made from materials like silicone, TPU, and leather amongst others, which protect your device from falls, bumps, and scratches. Most of them have raised edges that protect the screen and camera, ensuring that the device is fully protected. The device is protected in style with a wide array of styles, colors, and textures. Also, precision cutouts on the back covers make sure that buttons, ports, and the camera are easily accessible.
