The screen protector is a film, specially designed to protect the screen only from dust and superficial scratches. It does not protect the screen in case of a drop, as it is thin. 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 compatible with Xperia 1 V.
