The full face tempered glass is a full coverage hardened glass, specially designed to protect your phone's screen from scratches and other damage. In case of a phone drop, it does not guarantee that the screen won't 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 is a combination of tempered glass and protective film, as it has a ceramic coating for hardness like glass but also light elasticity like film. Scratch-resistant, repels fingerprints but reflects light. More durable than tempered glass. It has adhesive over its entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps with better application and seamless touch screen functionality. It also prevents dust from getting underneath, something that 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 phone screen. This way, it is not apparent that the screen has protection, but the curved edges are also protected. It is compatible with the iPhone 16.
