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 drops, it does not guarantee that the screen will not break, but it offers additional protection. It does not affect the functionality of the screen.
The black frame covers the entire screen surface, including the edges. It features adhesive across its entire surface, unlike edge glue tempered glass protectors that only have adhesive along the perimeter. This ensures better application and trouble-free touch screen operation. Additionally, it prevents dust from entering underneath, which can happen with edge glue protectors when the perimeter adhesive wears out.
It can be removed at any time without leaving marks or causing problems to the screen.
