The screen protector by Skyddar Innovation 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. It has adhesive over its entire surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better application and seamless touch screen functionality. It also does not allow dust to pass underneath, which can happen with edge glue when the perimeter adhesive wears off. It is 3D, which means it has undergone special processing to acquire curved edges that will cover the entire surface of the phone screen. This way it is not apparent that the screen has protection, but additionally, the curved edges are also protected. It is compatible with Redmi Note 15 Pro 4G.
