The tempered glass by Sonique is a hardened glass, specially designed to cover and protect your phone's screen from scratches and other damage. It does not affect the screen's functionality. In case of a phone drop, it does not guarantee that the screen will not break along with it, however, it is an additional protection. It has adhesive over its entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better application and seamless touch screen functionality. It also does not allow dust to pass underneath, which can happen with edge glue when the perimeter adhesive wears off. It is 2.5D, which means its perimeter has rounded edges for a smoother touch feel when using the screen. Useful for modern smartphones with curved screens. It is compatible with Galaxy S21+ 5G.
