Setup and Installation
Proper installation is crucial for optimal performance. Follow these steps carefully:
- Preparation: Before assembling, locate a dust-free area (e.g., a bathroom after a hot shower). Carefully remove any dust or dirt from the device's screen using a microfiber cloth. Ensure the screen is completely clean and dry.
- Align and Peel: Remove half of the thin cover film from one side of the screen protector. Carefully align the exposed side of the screen protector with your device's screen. Ensure it is centered and straight.
- Apply and Smooth: Once aligned, slowly lower the screen protector onto the screen. Use a soft cloth or a credit card (wrapped in a soft cloth) to gently smooth the protector from the center outwards, pushing out any air bubbles. Simultaneously, peel off the remaining half of the cover film as you apply.
- Final Touches: Smooth out any remaining small air bubbles towards the edges of the screen protector using the soft cloth or credit card. Minor bubbles should dissipate within 24-48 hours.

This visual guide provides four steps for installing the screen protector: cleaning the screen, peeling off the protective film, applying the protector, and smoothing out bubbles.
Operating Instructions
Once installed, the brotect AirGlass Screen Protector requires no special operating procedures. Your device's touch screen functionality will remain fully responsive, and the visual clarity will be preserved. The protector is designed to be case-friendly, allowing for seamless use with most device cases.
Maintenance
To maintain the clarity and effectiveness of your screen protector:
- Clean the screen protector regularly with a soft, lint-free cloth.
- For stubborn smudges, lightly dampen the cloth with water or a screen cleaner specifically designed for electronics. Avoid harsh chemicals or abrasive materials.
- Do not attempt to peel off and reapply the protector, as this may compromise its adhesive and lead to dust or bubbles.
Troubleshooting
- Bubbles after installation: Small bubbles are common immediately after installation. Most will disappear within 24-48 hours. For larger bubbles, gently push them towards the nearest edge with a soft cloth or credit card. Ensure the screen was thoroughly cleaned before application.
- Dust particles under the protector: If dust is trapped, it indicates insufficient cleaning prior to installation. While difficult to remove without damaging the adhesive, you may carefully lift a corner of the protector with a piece of tape, use another piece of tape to dab the dust particle, and then reapply. This should be done with extreme caution.
- Reduced touch sensitivity: Ensure the screen protector is properly adhered without any gaps or lifting. If the issue persists, verify that your device's touch settings are calibrated correctly.
