The screen protector of Sunshine 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 matte coating prevents the formation of fingerprints on its surface, as well as the reflection of light. In some cases, it may limit the clarity of the screen. It is compatible with Huawei P20.
