The full face tempered glass by Techwave is a full-coverage tempered glass, specially designed to protect your phone screen from scratches and other damage. In case of a phone drop, it does not guarantee that the screen won't break along with it, but it is an additional protection. It does not affect the screen's functionality. The black border covers the entire screen surface, including the edges. It has adhesive across its entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better fitting and seamless touch screen functionality. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out. It is 5D, which means it has undergone special processing to acquire curved edges that cover the entire surface of the phone screen. This way, it is not noticeable that the screen has protection, but the curved edges are also protected. It is compatible with the Redmi 14C / Poco C75.
