The full face tempered glass by Dux Ducis is a full coverage hardened glass, specially designed to protect your mobile screen from scratches and other damages. In case of a drop, it does not guarantee that the screen will not break along with it, but it provides additional protection. It does not affect the screen's functionality. The black border covers the entire surface of the screen, including the edges. It is compatible with the Redmi Note 12 Pro.
