The tempered glass is a reinforced glass specially designed to cover and protect your mobile phone's screen from scratches and other damages. It does not affect the screen's functionality. In case of a fall, it does not guarantee that the screen will not break along with it, but it provides an extra layer of protection. Its special treatment makes the mobile screen visible only from the front, blocking the view from any angle, which is useful if you frequently commute using public transportation. Conversely, it is not suitable for gaming or watching videos, as it darkens the screen. It is 3D, meaning it has undergone special processing to acquire curved edges that cover the entire surface of the mobile phone's screen. In this way, it is not obvious that the screen has protection, also safeguarding the curved edges. It is compatible with Galaxy A32 5G.
