The tempered glass from DeTech is a hardened glass, specially designed to cover and protect your mobile phone screen from scratches and other damages. It does not affect the screen's functionality. In case the phone is dropped, it does not guarantee that the screen will not break along with it, but it provides additional protection. It has adhesive across the entire surface, unlike edge glue protectors 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 protectors when the perimeter adhesive wears off. It is 3D, meaning it has undergone special processing to have curved edges that cover the entire surface of the mobile phone screen. This way, it is not obvious that the screen has protection, and the curved edges are also protected. It is compatible with the Galaxy S25 Ultra.
