The full face tempered glass is a hardened glass that covers the entire screen, specially designed to protect your tablet screen from scratches and other damages. In case of tablet drop, it does not guarantee that the screen will not break, but it provides additional protection. It does not affect the screen function. It is a combination of tempered glass and protective film, as it has a ceramic coating for hardness like glass but also light elasticity like film. It is resistant to scratches, repels fingerprints, but reflects light. More durable than tempered glass. Compatible with Galaxy Tab A7 Lite.
