Things You'll Need
Instructions
Open your DS handheld so you have access to the screen.
Run the edge of your plastic card along the area of the screen guard that is plagued with bubbles.
Run the card over the area repeatedly until all bubbles and creases are removed from the guard. For more stubborn bubbles and creases, proceed to the next step.
Peel the guard off of your DS screen by the corners and reapply it, making sure all sides and corners of the guard are flush with the sides and corners of the screen. These guards use a non-chemical adhesive so they are easy to remove and reapply, and they don't leave any messy residue on screen.
Use your card again to smooth out any bubbles or creases.
