Fixing Method
Clean the device's screen and back with a microfiber cloth and use a dust removal sticker.
Align and peel off the protective layer of the front screen guard, carefully placing it on the screen.
Smooth out any bubbles using a card or squeegee, pushing them towards the edges.
Repeat the process for the back screen guard, ensuring proper alignment.
Finalize by wiping both sides with a clean cloth to remove any fingerprints or smudges.
