3MK HardGlass Max Privacy Screen Protector for iPhone 12 Pro Max

The 3MK HardGlass Max Privacy Screen Protector for iPhone 12 Pro Max is a tempered glass shield engineered to provide privacy and durable display protection. It reduces side viewing angles so screen content remains visible primarily to the person holding the phone, while retaining touch responsiveness and clarity for direct viewing. The hardened surface resists scratches and everyday impacts, helping to preserve the original screen appearance and touch function over time.

Advantages

This privacy glass combines a hard, scratch-resistant surface with an anti-peep microstructure that narrows lateral viewing angles without significantly affecting on-axis brightness. The protector is designed for quick, bubble-free installation and maintains full compatibility with compatible phone cases. Its oleophobic coating reduces fingerprints and eases cleaning, while the tempered construction increases resistance to impacts compared with unprotected glass.

• Users who need on-screen privacy in public spaces or commuting environments

How to use

Clean the iPhone 12 Pro Max front surface thoroughly with the included alcohol wipe and dust-removal sticker, ensuring no particles remain on the screen. Peel the protective backing from the glass and align the protector with the phone's edges and sensor openings. Gently lower the glass onto the display and press in the center to allow the adhesive to spread outward; any small bubbles typically disappear within 24–48 hours. If necessary, use a soft cloth to smooth remaining bubbles and ensure full adhesion.

Usage recommendations

For best results, install the screen protector in a dust-free environment and avoid reapplying the same protector after removal. Clean the surface with a microfiber cloth and mild cleaner; do not use abrasive materials. Replace the protector if it sustains deep scratches, cracks, or loses adhesion to maintain privacy and protection performance.
