How to use
Before installation, ensure the smartphone screen is completely clean and free of dust, fingerprints, or oils using a microfiber cloth and cleaning solution. Carefully align the protector with the edges of the device display, ensuring all cutouts for sensors or cameras are correctly positioned. Gently press the center of the glass to initiate the adhesive process, allowing it to spread evenly across the screen. If any small air bubbles appear, gently push them toward the edges of the screen until they disappear.
What to consider before purchase
- Ensure your device model is either the Samsung Galaxy A37 or Galaxy A57
- Verify that your current phone case does not overlap with the screen area to prevent lifting
- Clean the installation environment to minimize dust particles
Usage recommendations
For the best results, perform the installation in a dust-free environment such as a bathroom after running a hot shower to settle airborne particles. Avoid touching the adhesive side of the glass during application to prevent fingerprints.
