How to use

Clean the rear surface of the Oppo Reno 3 thoroughly with a lint-free cloth and, if provided, an alcohol wipe to remove dust, oils and fingerprints. Peel off the protective film from the adhesive side of the GrizzGlass protector, align it carefully with the camera cutouts and edges, then place it gently onto the rear panel. Apply light pressure from the center outward to remove air bubbles and ensure full adhesion. If small bubbles remain, smooth them out toward the nearest edge with a soft cloth.

Usage recommendations

For best results, install the back protector in a dust-free environment and avoid removing and reapplying the protector repeatedly, as this may reduce adhesive performance. If the protector becomes cracked or heavily scratched, replace it to maintain optimal rear-panel protection.
