Tempered privacy glass GrizzGlass SecretGlass for Samsung Galaxy S25 Ultra

GrizzGlass SecretGlass for Samsung Galaxy S25 Ultra is a tempered privacy glass screen protector engineered to reduce side viewing angles while maintaining touch sensitivity and image clarity for the user directly in front of the display. The fitted glass layer adheres to the device's screen profile and creates a privacy filter that limits visibility from the sides without significantly altering color or brightness for normal use. This protector is intended for everyday scenarios where on-screen data should remain visible only to the device holder.

Advantages

The privacy tempered glass minimizes sideways viewing so that screen content is visible primarily to the person standing directly in front of the phone. The hardened glass surface increases resistance to scratches and light impacts compared with unprotected displays. Optical clarity and touch responsiveness are preserved, enabling the use of gestures, typing and biometric features without additional calibration. Installation on the Samsung Galaxy S25 Ultra is designed to provide a seamless fit that keeps the touch area unobstructed.

Suitable for

• Commuters who use their phone on public transport and need to protect private content
• Professionals working in open offices or shared spaces
• Anyone using the device in crowded places such as cafes, airports or conferences
• Users who want to prevent shoulder surfing while handling sensitive messages or financial information

How to use

Before applying the tempered privacy glass, clean the phone screen thoroughly with the included wet and dry wipes or a lint-free cloth to remove dust, fingerprints and oils. Align the protector with the device display, starting from one edge and gradually lowering it into place to avoid trapping air. Press gently from the center outward to ensure full adhesion and remove any bubbles. If small bubbles remain, they typically disappear within 24–48 hours; larger bubbles can be smoothed out by applying gentle pressure with a soft card wrapped in a microfiber cloth. The protector is intended for use as a direct replacement for the device's unprotected screen and does not require software adjustments.

Usage recommendations

For best results, apply the privacy glass in a dust-free environment and avoid lifting the protector after initial installation to maintain optimal adhesion. Clean the glass using a soft, lint-free cloth and a mild screen-safe cleaner; avoid abrasive materials. If the privacy effect or adhesion degrades after prolonged use, consider replacing the protector to ensure continued privacy and impact protection.
