5. Usage and Care
Once installed, the screen protector requires minimal special care. Its ultra-thin design ensures that your smartwatch's touch functionality remains unaffected. To maintain clarity, regularly wipe the screen with the provided microfiber cloth to remove fingerprints and smudges. Avoid using harsh chemicals or abrasive materials, as these can damage the protector's surface.
6. Troubleshooting
Common Issues and Solutions:
- Bubbles After Installation: Small bubbles may disappear naturally within 24-48 hours due to the TPU material's flexibility. For larger bubbles, gently lift the nearest edge of the protector and re-apply, using the squeegee to push the air out.
- Dust Particles Under Protector: If dust is trapped, carefully lift the protector from the nearest edge, use a dust-removal sticker (not included, but often found with screen protectors) or a piece of tape to dab the dust off both the screen and the protector's adhesive side, then re-apply.
- Edges Not Sticking: Ensure the screen was thoroughly cleaned and free of oils or residue before application. Press firmly along the edges with the squeegee or your finger for a few seconds.
- Reduced Touch Sensitivity: This is rare due to the protector's thinness. Ensure the protector is fully adhered without air gaps. If issues persist, verify your smartwatch settings.
