The full face tempered glass from Volte-Tel 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 has adhesive on its entire surface, unlike edge glue glasses that only have adhesive on their perimeter. This helps in better application and smooth touch screen operation. 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. Compatible with Xiaomi Redmi Pad SE.
