The tempered glass of Lito is a hardened glass, specially made to cover and protect the screen of your mobile phone from scratches and other damages. It does not affect the functionality of the screen. In case of a drop, it does not guarantee that the screen will not break along with it, however, it provides an additional protection. It is of UV Liquid type, a relatively new type of tempered glass consisting of an adhesive, which is evenly spread across the entire surface of the mobile screen, including the cracks, and a UV lamp that hardens this adhesive. The process requires more time than the classic protections and must be done according to the manufacturer's instructions for an ideal result. The special processing makes the screen of the mobile visible only from the front, obstructing vision from any angle. This protection is useful if you frequently travel on public transportation and do not want those around you to look at your screen. However, it is not suitable for gaming or video watching as it darkens the screen. It is 3D, which means it has undergone special processing to acquire curved edges that cover the entire surface of the mobile phone screen. This way, it is not apparent that the screen has protection, but the curved edges are also protected. It is compatible with Galaxy S21 5G.
