The tempered glass 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. It is compatible with Huawei P30 Pro.
