The full face tempered glass by Techsuit is a full coverage tempered 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 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 glasses that only have adhesive on their perimeter. This helps with better fitting and seamless touch screen operation. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out. It is compatible with the OnePlus Nord CE 4 Lite.
