I recently used my 3DS for the first time, so I decided to get a screen protector. The top one worked just fine, but inbetween dusting off the bottom one and applying it, a few specks of dust fell onto the screen, and now they show up with air bubbles. So what I'm wondering is if it's possible to take off a screen protector and still have it work, or if it's possible to use a credit card or the smoothing tool to get rid of those specks without scratching the screen.
