My bookbag dropped with my 3DS XL inside (only protection was a sweater tied around it) and when I checked on it after, I saw this had happened:
My touch screen semmed to have sunk in a bit and now there's a tiny space where the light shines though. Luckily, everything else is fine, both screens work, and all the buttons funtion normally.
My only concern is that in the future, I'm afraid my screens will catch some dust that might get trapped within the system, or stay under the screen(s). Is there anything I could do? It's so minor, I know, but I kind of just got it and I'm really upset about my otherwise flawless 3DS XL.
