The screen protector by Hoco is a film, specially designed 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 screen's functionality. Its matte coating prevents fingerprints on its surface, as well as light reflection. In some cases, it may limit screen clarity. Flexible, made of hydrogel, it is easily applied without forming bubbles and self-repairs from scratches. Provides excellent clarity but also increased reflections. It is compatible with Galaxy A57.
