Technovo's tempered glass is a hardened glass, specially made to cover and protect your mobile phone's screen from scratches and other damage. It does not affect the operation of the screen. In the event of a fall of the mobile phone, it does not guarantee that the screen will not break with it, however, it is an additional protection. Its special treatment makes the mobile phone screen visible only from the front, blocking vision from any angle. This protection is useful if you often travel by public transport and do not want those around you to look at your screen. On the contrary, it is not suitable for gaming or watching videos, as it darkens the screen. It is compatible with the Galaxy S24 Ultra.
