The full face tempered glass is a full coverage tempered glass specially designed to protect your mobile screen from scratches and other damages. In the event of a fall, the screen may still crack, but it provides additional protection. It does not affect the functionality of the screen.
The black frame covers the entire surface of the screen, including the edges. It features adhesive across its entire surface, unlike edge glue tempered glasses that only have glue around the perimeter. This property helps ensure better application and operation of the touch screen without issues. Additionally, it prevents dust from passing underneath, which can occur with edge glue glasses if the perimeter glue deteriorates.
