## Long description

Matte Privacy Screen Protector 3MK for Ulefone Armor 21 provides a matte anti-glare surface and a privacy filter designed specifically for the Ulefone Armor 21 display. The protector limits side viewing angles to help keep on-screen content visible only to the user, reduces reflections and fingerprints with its matte finish, and offers scratch protection to preserve the display surface during everyday use.
Advantages
The matte surface reduces glare and minimizes visible fingerprints, while the integrated privacy filter narrows lateral viewing angles to protect sensitive information from bystanders. The protector also adds a layer of scratch resistance to the original screen without significantly altering touch sensitivity or display clarity when viewed head-on.
Suitable for
Commuting and public transport use

How to use
Clean the Ulefone Armor 21 screen thoroughly with a lint-free cloth and, if provided, the included cleaning wipe and dust-removal sticker. Align the protector with the display edges and carefully apply it from one side, smoothing out air bubbles toward the edges with a soft card or cloth. If small bubbles remain, they typically disappear within a few days of normal use. Replace the protector if it becomes damaged or its privacy effect is compromised.
Usage recommendations
For best results, apply the protector at room temperature on a flat, dust-free surface and avoid repositioning multiple times. Clean the screen protector with a soft, slightly damp microfiber cloth; do not use abrasive cleaners or solvents.
