The 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. In case of a drop, there is no guarantee that the screen won't break, but it provides additional protection. It is 2.5D, meaning that its perimeter has rounded edges for a smoother feel when using the screen. It is useful for modern smartphones with curved screens. It is compatible with the Motorola Moto32s.
