The full face tempered glass by Techsuit is a full-coverage tempered glass, specially designed to protect your mobile screen from scratches and other damage. In case of a fall, it does not guarantee that the screen won't break along with it, but it is an additional protection. It does not affect the screen's functionality. The black border covers the entire screen surface, including the edges. It has adhesive across its entire surface, unlike edge glue protectors that only have adhesive on their perimeter. This helps in better application and seamless touchscreen functionality. It also prevents dust from getting underneath, which can happen with edge glue protectors when the perimeter adhesive wears out. Its special processing makes the mobile screen visible only from the front, blocking visibility from any angle. This protection is useful if you frequently use public transportation and don't want those around you to look at your screen. On the other hand, it is not suitable for gaming or watching videos, as it darkens the screen. It is compatible with the Redmi Note 12 4G.
