How to use
Before applying, clean the Galaxy S21+ display thoroughly with a lint-free cloth and any included alcohol wipe, then remove dust with a dust-removal sticker or dry cloth. Align the protector to the device edges and camera cutouts, lower it gently starting from one edge and press toward the opposite edge to eliminate air bubbles. If minor bubbles remain, smooth them outward using a soft card or the included squeegee until the protector adheres evenly.
Usage recommendations
For best results, apply the protector in a dust-free environment and at room temperature. Use with compatible slim cases to avoid edge lifting. Clean with a microfiber cloth and avoid abrasive cleaners; replace the protector if it sustains deep cracks or significant chipping to ensure continued screen protection.
