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. Its special processing makes the phone screen visible only from the front, preventing visibility from any angle. This protection is useful if you often travel by public transport and do not want those around you to look at your screen. On the contrary, it is not suitable for gaming or watching videos, as it darkens the screen. It is compatible with Honor 50, Nova 9.
