The tempered glass of Volte-Tel is a hardened glass, specially made to cover and protect the screen of your mobile phone from scratches and other damages. It does not affect the functionality of the screen. In case of a drop, it does not guarantee that the screen will not break along with it, however, it provides an additional protection. It has adhesive on its entire surface, unlike edge glue protectors that only have adhesive on their perimeter. This helps in better application and smooth operation of the touch screen. It also prevents dust from passing underneath, which can happen with edge glue when the perimeter adhesive wears off. It is 2.5D, which means that its perimeter has rounded edges for a smoother touch experience when using the screen. Useful for modern smartphones with curved screens. It is compatible with Redmi 13C 4G / Poco C65 4G.
