The full face tempered glass is a full-coverage tempered glass specially designed to protect your mobile screen from scratches and other damage. In the event of a fall, it does not guarantee that the screen will not break, but it provides additional protection. It does not affect the function of the screen.
The black frame covers the entire surface of the screen, including the edges. It has adhesive across the entire surface, unlike edge-glue glasses that have glue only on the perimeter. This helps ensure better application and seamless touch screen operation. Additionally, it prevents dust from getting underneath.
It can be removed at any time without leaving marks or causing problems to the screen.
