Tempered glass is a hardened glass, specially designed to cover and protect your mobile phone screen from scratches and other damages. It does not affect the functionality of the screen. In case of a fall, it provides additional protection, although it does not guarantee that the screen will not break. Its special treatment allows visibility of the screen only from the front, blocking the view from any angle. This protector is useful in crowded environments, such as public transportation, as it limits access to the screen from those around you. It is not suitable for gaming or watching videos, as it may darken the screen.
