The lights are on
so I just noticed this recently and not sure if this is a common occurrence or not. my back cover right under the him button on the front seems to have a little give. It's not flush with the system, and when I press up on it and move and becomes flush with the system casing. It's the back cover, not the casing itself. I was just wondering if this is common with 3DS XL's or if it' just whatever.
I once had a friend over and i ended up dropping it and the cover stuck out, so we had to find a screw driver and take off the battery cover and plop it back down and we ended up fixing it. Of course, we had problems putting it back on, but we fixed the problem.
I noticed right away that the cover of the 3DS XL was kind of flimsy. I bought my 3DS XL when it was first released in the US, and I have not had any issues like what you describe. When I noticed the flimsy cover I thought, " Oh great, I wonder how long before this breaks..." My 3DS XL has been dropped, kicked, stepped on, and handled by my toddler children. Other than some scrapes and scratches, my 3DS XL works as good as new.
