The full face tempered glass is a full coverage tempered glass designed to protect your mobile screen from scratches and other damages. In case of a fall, it provides additional protection, but does not guarantee that the screen will not be damaged. It does not affect the functionality of the screen.
The black frame covers the entire surface of the screen, including the edges. It has adhesive all over its surface, unlike edge glue screens, which have adhesive only on the perimeter. This allows for better application and hassle-free touch screen operation, while preventing dust from entering from underneath.
It can be removed at any time without leaving marks or causing issues on the screen.
