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 will not break along with it, however, it is an additional protection. It does not affect the screen's functionality. It is a combination of tempered glass and protective film, as it has a ceramic coating for hardness like glass but also slight elasticity like film. Resistant to scratches, repels fingerprints but reflects light. More durable than tempered glass. It is compatible with iPhone 14 Plus / 13 Pro Max.
