4. Installation Guide
Follow these steps for a smooth and bubble-free application of your screen protector:
- Clean the Screen: Thoroughly clean the device screen using the provided microfiber cloth to remove all dust, fingerprints, and smudges. Ensure the screen is completely dry.
- Align the Protector: Carefully peel off a small portion of the protective layer from the screen protector. Align the protector with the device's screen, paying attention to cutouts for cameras, sensors, and speakers.
- Apply and Smooth: Slowly peel off the rest of the protective layer while simultaneously applying the screen protector to the device. Use the installation tool (squeegee) to gently push out any air bubbles towards the edges.

5. Maintenance and Care
To ensure the longevity and clarity of your Bruni Screen Protector:
- Clean the screen protector regularly with a soft, lint-free cloth, such as the provided microfiber cloth.
- For stubborn smudges, lightly dampen the cloth with water or a screen-safe cleaning solution. Avoid harsh chemicals or abrasive materials.
- Do not attempt to peel off or reposition the protector frequently, as this may introduce dust or reduce adhesion.
- Avoid exposing the device with the protector to extreme temperatures or direct sunlight for prolonged periods.
6. Troubleshooting
Common issues and their solutions:
Bubbles After Installation:
Small bubbles can sometimes appear immediately after installation. Most small bubbles will disappear naturally within 24-48 hours as the adhesive settles. For larger bubbles, gently lift the nearest edge of the protector and re-apply, pushing the bubble out with the squeegee.
Dust Particles Under the Protector:
Dust particles are usually introduced during the cleaning or application process. If a dust particle is causing a noticeable bubble, carefully lift the corner of the protector closest to the dust, use a dust-removal sticker or a piece of tape to lift the dust, and then re-apply the protector.
Edges Not Sticking:
Ensure the screen edges were thoroughly cleaned and free of oil or dust before application. Press firmly on the edges with the microfiber cloth for a few seconds to help them adhere. If the issue persists, the protector may need to be replaced.
