The tempered glass by Lito 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 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 3D, 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 Huawei P40 Pro.
