High-quality Ringke Easy Slide tempered glass with a protective filter function is an ideal way to protect the screen from damage and also limit its visibility to outsiders. The polarizing filter limits the visibility of the screen at an angle of 28° and completely reduces it at an angle of 40°. The glass has a hardness of 9H, which is sufficient to effectively protect the screen, with high resistance of the glass itself to superficial scratches. It is also covered with an oleophobic layer, which reduces the degree of fingerprints leaving on the screen. Additionally, to ensure easy installation, the Easy Slide installation tool is included to make glass application simpler and more precise. Trust the Ringke brand and its excellent quality! * The glass is cut only to the flat part with an emphasized structure, in accordance with and on the basis of the die prepared by the manufacturer of a given phone model. ** Due to the variety of milling, a slight halo of air may form around the screen after installing the protective glass on the screen. This is a natural situation and depends on the device itself. INSTALLATION INSTRUCTIONS: 1. Start installation in the bathroom right after bathing - the water vapor will absorb all the dust from the atmosphere and it will not interfere with your installation. 2. Thoroughly clean and degrease the surface of the screen, then use a dry cloth to polish it to a shine. Make sure there are no dust particles left. 3. Put the frame with the glass already mounted on your phone - it will ensure a precise fit and make application easier. 4. Pull the starter film to start the process of automatically sticking the glass on the screen. 5. Press the glass in the designated areas. Do this thoroughly so that the adhesive layer bonds well to the surface. 6. Remove the frame and remove any air bubbles by swiping your finger in a circular motion. Done! Enjoy a perfectly applied screen protector.
