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. 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 Galaxy A50 / A30s.
