The blue thing that comes with the screen protector is commonly known as a dust sticker or dust removal sticker. Its purpose is to ensure that your screen is clean and free of any dust particles or debris before applying the screen protector.
When you open the package of a screen protector, you will often find a small blue sticker sheet included. This sheet usually contains multiple sticky blue tabs or stickers. These stickers are specifically designed to remove any dust or lint that may be present on your screen surface.
To use the blue sticker, you need to follow a few simple steps. First, make sure your hands are clean and free of any dirt or oil. Then, peel off one of the blue tabs from the sticker sheet. Gently press the sticky side of the tab onto your screen and lift it off. You will notice that the tab picks up dust particles and other small debris that may have been on your screen.
It’s important to be thorough when using the blue sticker. You may need to repeat the process multiple times, using different tabs, to ensure that your screen is completely clean. Pay attention to the corners and edges of your screen, as these areas are more prone to collecting dust.
Once you have used the blue sticker to remove any dust from your screen, you can then proceed to apply the screen protector. The purpose of this sticker is to create a clean and smooth surface for the protector to adhere to. By removing dust and debris, you can achieve a bubble-free application and ensure that the screen protector adheres properly to your screen.
In my personal experience, using the blue sticker has been quite effective in preparing the screen for screen protector installation. It helps eliminate any unwanted particles that could potentially create bubbles or affect the clarity of the screen. By taking the time to properly clean the screen with the blue sticker, I have found that the screen protector adheres better and provides a smoother overall finish.
To summarize, the blue thing that comes with the screen protector is a dust removal sticker. Its purpose is to remove any dust or debris from your screen before applying the screen protector. By using the blue sticker, you can achieve a clean and smooth surface, ensuring a bubble-free installation and optimal clarity for your screen protector.
