The full face tempered glass is a full coverage tempered glass, specially designed to protect your mobile screen from scratches and other damages. In case of a mobile drop, it does not guarantee that the screen will not break along with it, however, it is an additional protection. It does not affect the screen's functionality. The black border covers the entire surface of the screen, including the edges. It has adhesive on the entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better application and seamless touch screen functionality. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out. It is compatible with the Redmi 10C.
