How to use

Before installation, clean the device display thoroughly with a microfiber cloth and any included alcohol wipe to remove dust, fingerprints and oils. Use the supplied dust-removal sticker or a clean adhesive tape to lift remaining particles. Align the protector with the screen edges and cutouts, then gently lower it onto the display starting from one edge; allow the adhesive to self‑spread and press out any air bubbles toward the nearest edge using a soft card or cloth. If necessary, lift and re-align once before full adhesion occurs.

Usage recommendations

Apply the protector in a dust-free environment to minimize trapped particles. Replace the glass if it becomes cracked or deeply scratched to maintain full protection and optical clarity.
