The full face tempered glass is a full-coverage tempered glass designed specifically to protect your mobile screen from scratches and other damages. In case of a fall, it provides additional protection, although it does not guarantee that the screen will not break.
It features adhesive across the entire surface, unlike edge glue glass protectors that only have glue around the perimeter. This results in better application and trouble-free touch screen operation. Additionally, it prevents dust from getting underneath, which can occur with edge glue protectors when the perimeter adhesive wears out.
