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 matte coating prevents fingerprints on its surface, as well as light reflection. In some cases, it may limit screen clarity. It is compatible with Nokia G10, G20, Deva Rugged Armor. See full description
