The tempered glass is a hardened glass specifically designed to cover and protect the mobile phone's screen from scratches and damages. It does not affect the screen's functionality. In case of a fall, it provides additional protection, although there is no guarantee that the screen will not break.
It is 2.5D, meaning that the perimeter has rounded edges for a smoother feel during use. Suitable for modern smartphones with curved screens. It is compatible with the Moto E20.
