The tempered glass is a hardened glass, specially designed to cover and protect your phone's screen from scratches and other damage. It does not affect the screen's functionality. In case of a phone drop, it does not guarantee that the screen will not break along with it, however, it is an additional protection. It is UV Liquid type, a relatively new kind of tempered glass consisting of an adhesive, which is evenly spread over the entire surface of the phone's screen, even its cracks, and a UV lamp that hardens this adhesive. The process takes more time than traditional protections and should be done according to the manufacturer's instructions for an ideal result. It has adhesive over its 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 does not allow dust to pass underneath, which can happen with edge glue when the perimeter adhesive wears off. It is compatible with Xiaomi 12 / 12XRealme 12x.
