The full face tempered glass is a full coverage tempered glass, specially designed to protect your mobile phone's screen from scratches and other damages. In case of a drop, it does not guarantee that the screen won't break along with it, but it provides additional protection. It does not affect the screen's functionality.
The black frame covers the entire surface of the screen, including the edges. It has adhesive over the entire surface, unlike edge glue glass protectors, which only have adhesive around the perimeter. This contributes to better application and smooth touchscreen operation. Additionally, it prevents dust from passing underneath, which can happen with edge glue protectors if the perimeter adhesive wears out.
