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

The 3MK HardGlass Max Privacy for iPhone 12/12 Pro is a tempered glass screen protector combining hardened surface protection with a built-in privacy filter. Designed for devices with flat front glass, it preserves touch sensitivity and display clarity while restricting side viewing angles to reduce visual exposure in public environments. The protector features a 9H surface hardness to resist everyday scratches and light impacts and offers an ultra-thin profile for compatibility with most cases.

Advantages

The privacy layer narrows viewing angles so the screen is visible only from directly in front, helping to protect personal information. The 9H tempered glass provides high scratch resistance and improved impact protection compared with standard plastic films. Oleophobic coating reduces fingerprints and makes cleaning easier, while the precise cut and thin design keep touch responsiveness and support face recognition and in-screen sensors where applicable. Installation is designed to be bubble-free and straightforward.

Suitable for

• Daily use to protect iPhone 12 or iPhone 12 Pro displays from scratches and scuffs
• Privacy protection when using the phone in public transport, open offices, or crowded places
• Users who require high touch sensitivity and compatibility with cases

Key specifications

How to use

Before application, clean the display thoroughly using a microfiber cloth and the included cleaning wipe to remove dust, oils and particles. Align the protector with the device edges and cutouts, then lower it gently onto the screen starting from one edge to minimize trapped air. Press centrally and smooth outward to ensure full adhesion and eliminate remaining bubbles. If small bubbles persist, they typically disappear within 24–48 hours as the adhesive settles.

Usage recommendations

To maintain privacy performance and surface protection, avoid using abrasive cleaners or sharp tools on the protector. Replace the protector if it sustains deep cracks, chips or significant loss of the oleophobic layer. For optimal privacy effect, view the screen from straight on and avoid strong backlighting that can reduce contrast.
