The screen protector is a membrane, specially made 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 functionality of the screen. It is a combination of tempered glass and protective membrane, as it has a ceramic coating for hardness like glass but also light elasticity like a membrane. It is scratch-resistant, repels fingerprints but reflects light. More durable than tempered glass. It is compatible with Galaxy Note 10.
