The full face tempered glass by Powertech is a hardened glass with full coverage, specially designed to protect your mobile screen from scratches and other damages. In case of a phone drop, it does not guarantee that the screen will not break along with it, but it is an additional protection.

It does not affect the screen's functionality. The black border covers the entire surface of the screen, including the edges. It has adhesive across its entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better fitting and seamless touchscreen functionality. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out.

It is 5D, which means it has undergone special processing to acquire curved edges that cover the entire surface of the mobile phone screen. This way, it is not apparent that the screen has protection, but it also protects the curved edges.

It is compatible with the Galaxy A04s.
