Tempered glass is a hardened glass, specially designed to cover and protect your mobile screen from scratches and other damages. It does not affect the functionality of the screen. Its oleophobic coating helps prevent fingerprints and makes it very easy to clean.
In case of a mobile drop, it does not guarantee that the screen will not break along with it, but it is an additional protection. It is 2.5D, which means that its perimeter has rounded edges for a smoother touch feel when using the screen. Useful for modern smartphones with curved screens. It is compatible with the Galaxy M33.
