## Summary description

GrizzGlass SecretGlass is a tempered privacy screen protector designed for the Ulefone Armor 28 Ultra. It provides a hardened glass surface that resists scratches and impacts while narrowing viewing angles to protect on-screen content from side viewing. The protector preserves touch sensitivity and image clarity for everyday use, commuting, and public spaces.

## Long description

GrizzGlass SecretGlass for Ulefone Armor 28 Ultra is a tempered privacy screen protector engineered to reduce side viewing and protect the device display from scratches and impacts. The hardened glass surface retains touch responsiveness and preserves image clarity while narrowing viewing angles so that on-screen content remains visible only to the person directly in front of the screen. This protector is shaped to match the display area of the Ulefone Armor 28 Ultra and supports everyday use in environments where privacy and display protection are needed.
Advantages
The tempered glass offers durable surface hardness that resists everyday scratches and light impacts while maintaining the original touch sensitivity of the touchscreen. The privacy filter element narrows lateral viewing angles to reduce visual access from side positions without significantly altering color fidelity or brightness when viewed head-on. The protector is thin enough to work with touch gestures and most in-screen sensors and preserves the legibility of text and images for normal use.
Suitable for
Commuting on public transport where you want to keep screen content private
Using your phone in cafes, airports, or crowded public spaces
Work environments that require discreet handling of messages or documents
Outdoor use where display protection against scratches and minor impacts is needed
Key specifications
Material: tempered glass with integrated privacy filter
Thickness: low-profile design preserving touch sensitivity
Surface finish: scratch-resistant hard coating
Optical performance: retains front-facing clarity with reduced lateral viewing angle
Compatibility: shaped for the Ulefone Armor 28 Ultra display area
How to use
Before application, clean the device screen thoroughly using a lint-free cloth and any included alcohol wipe to remove dust, fingerprints, and oils. Align the protector with the phone display starting from one edge and slowly lower it into place, ensuring the cutouts and edges match the device. If bubbles appear, press them gently toward the nearest edge with a soft card or cloth. Allow a short settling period for full adhesion before returning the device to heavy use.
Usage recommendations
For best results, apply the protector in a dust-free environment and handle by the edges to avoid leaving fingerprints on the adhesive side. Replace the protector if the privacy layer becomes scratched or damaged to maintain both privacy function and screen protection.
