The full face tempered glass is a full coverage hardened glass, specially designed to protect your mobile screen from scratches and other damages. In case of a fall, 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 across its entire surface, unlike edge glue protectors 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 protectors when their perimeter adhesive wears out. Its special processing makes the mobile screen visible only from the front, blocking vision from any angle. This protection is useful if you frequently use public transportation and do not want those around you to look at your screen. On the contrary, it is not suitable for gaming or watching videos, as it darkens the screen.
It is compatible with the Redmi Note 11 Pro / 11 Pro+.
