The screen protector of Hoco is a membrane, specially made to protect the screen only from dust and superficial scratches. It does not protect the screen in case of a drop, as it is thin. It does not affect the functionality of the screen. The special processing makes the screen of the mobile visible only from the front, obstructing vision from any angle. This protection is useful if you frequently travel on public transportation and do not want those around you to look at your screen. However, it is not suitable for gaming or video watching as it darkens the screen. Flexible, made of hydrogel, it is easily applied without forming bubbles and repairs itself from scratches. It provides excellent clarity but also increased reflections. It is compatible with Redmi Note 13 4G.
