The tempered glass by Ancus is a hardened glass, specially designed to cover and protect your mobile screen from scratches and other damages. It does not affect the screen's functionality. In case of a mobile drop, it does not guarantee that the screen will not break along with it, but it provides additional protection. It has adhesive on its entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better fitting and seamless touch screen functionality. It also prevents dust from getting underneath, something that can happen with edge glue when the perimeter adhesive wears out. It is compatible with the Redmi Note 11/11S.
