Package Contents:
- 1 x VASTKING SA8 Tempered Glass Screen Protector
- 1 x Alcohol Prep Pad
- 1 x Lint-Free Cloth
- 1 x Dust Absorbent Sticker
- Guide Stickers (optional for alignment)
Installation Steps:
- Prepare Your Workspace: Choose a clean, dust-free environment. Wash your hands thoroughly to avoid transferring oils or dirt to the screen.
- Clean the Tablet Screen: Use the provided alcohol prep pad to thoroughly clean the tablet screen. Ensure all smudges, fingerprints, and dirt are removed.
- Dry the Screen: Immediately use the lint-free cloth to dry the screen completely. Ensure no moisture or streaks remain.
- Remove Dust Particles: Use the dust absorbent sticker to gently dab the screen and lift any remaining dust particles. Inspect the screen carefully under light to ensure it is completely dust-free.
- Peel Off Protective Film: Carefully peel off the protective film from the adhesive side of the tempered glass screen protector. Avoid touching the adhesive surface.
- Align the Protector: Hold the screen protector by its edges and carefully align it with your tablet screen. Pay close attention to the cutouts for the camera and sensors. You may use the guide stickers to help with precise alignment before fully lowering the protector.
- Apply the Protector: Once aligned, gently lower the screen protector onto the tablet screen. Press lightly on the center of the protector. The adhesive will begin to spread automatically.
- Remove Bubbles: If any bubbles appear, gently push them towards the edges of the screen using the lint-free cloth or a soft card (not included). Small bubbles should dissipate over 24-48 hours.

3. Operating and Features
Once installed, your VASTKING SA8 Screen Protector enhances your tablet experience with several protective and functional features.
Enhanced Protection:
- Scratch Resistance (9H): The tempered glass provides superior resistance against scratches from keys, coins, and other sharp objects, maintaining the pristine condition of your tablet's display.

4. Maintenance
To ensure the longevity and optimal performance of your screen protector, follow these simple maintenance guidelines:
- Regular Cleaning: Gently wipe the screen protector with a soft, lint-free cloth to remove dust and smudges.
- Stubborn Marks: For more stubborn marks, lightly dampen the lint-free cloth with water or a screen-specific cleaning solution. Avoid using harsh chemicals, abrasive materials, or alcohol-based cleaners (other than the initial installation pad) as they may damage the oleophobic coating.
- Avoid Excessive Force: While the protector is durable, avoid applying excessive force or sharp objects directly to the screen to prevent damage.
5. Troubleshooting
Here are solutions to common issues you might encounter:
Bubbles After Installation:
- Small Bubbles: Minor bubbles often disappear naturally within 24-48 hours as the adhesive settles.
- Large Bubbles: If large bubbles persist, gently lift the nearest edge of the screen protector (using a thin, non-sharp object like a credit card edge, if necessary) and slowly re-apply, pushing the bubble out towards the edge with a lint-free cloth. Ensure no dust is trapped underneath.
Dust Particles Underneath:
- Dust particles are the primary cause of persistent bubbles. If dust is trapped, carefully lift the screen protector from the nearest corner and use the dust absorbent sticker to gently remove the particle from both the screen and the adhesive side of the protector. Re-apply as per installation steps.
Screen Protector Not Sticking Properly:
- Ensure the screen was thoroughly cleaned and dried before application. Any oils or residue can prevent proper adhesion.
- If the protector has been removed and re-applied multiple times, the adhesive may lose effectiveness. Consider using a new protector.
