The tempered glass by Techwave is a hardened glass, specially designed to cover and protect your phone's screen from scratches and other damage. It does not affect the screen's functionality. 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 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 5D, which means it has undergone special processing to acquire curved edges that will cover the entire surface of the phone screen. This way it is not apparent that the screen has protection, but additionally, the curved edges are also protected. It is compatible with Galaxy A22 5G.
