The back cover of the Galaxy S9 by Samsung is designed to protect the phone from day-to-day damage such as drops, scratches, and impacts. Made of materials like TPU, silicone, and polycarbonate, these covers do a great job of protection with an excellent sense of style. Most covers have raised edges around both the screen and the camera to prevent them from coming into direct contact with any surface for full protection. The covers are light, thin, and form-fitting; they keep the phone sleek while still managing to provide easy access to all buttons and jacks. Available in a wide array of colors and designs, the Galaxy S9 back cover has joined forces between practicality and style.
