The full face tempered glass by Whitestone 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 UV Liquid type, a relatively new kind of tempered glass consisting of an adhesive, which is evenly spread over the entire surface of the phone's screen, even its cracks, and a UV lamp that hardens this adhesive. The process takes more time than traditional protections and should be done according to the manufacturer's instructions for an ideal result. 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 S23.
