The full face tempered glass by Sonique is a full coverage tempered glass, specially designed to protect your phone screen from scratches and other damages. In case of a phone drop, it does not guarantee that the screen will not break along with it, but it is an additional protection. It does not affect the screen's functionality. It has adhesive across its entire surface, unlike edge glue glasses that have adhesive only around the perimeter. This helps with better application and seamless touchscreen functionality. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out. It is 2.5D, meaning its perimeter has rounded edges for a smoother touch feel during screen use. Useful for modern smartphones with curved screens. It is compatible with the Xiaomi Redmi Note 9S/9 Pro.
