So, after what happened with my 3DS going through the repair process of the outer cameras, I called them up and talked to a rep. I gave the rep my information to acknowledge that I was the original sender of the unit that was sent off for repairs the first time, and then she talked about what was repaired. Interestingly, what was repaired was not what I explained in the original repair form. Based on Nintendo's observations, they saw that my L and R buttons were damaged. I hadn't experienced any problems with them, and while I found that quite odd that they looked into that, I did remember mentioning in the report that "when going into the camera app form the Home menu via the L & R buttons...", so I guess that's how they found out that problem (if there really was one). The rep looked into the report I originally made, and did see that I made note of the camera issues, so she had me go into detail about the problems, just to make sure that when I do send in my 3DS for the 2nd time, they will be much thorough in their investigation.
While I didn't get any freebies because of a mistake they made, I am happy that they did find a different problem (again, if it really was there), and fixed that before it became a problem for me. So, hopefully when I get my 3DS back this next time, it will be fully operational. I was courteous during my phone call this time, but if I have to call them again for the same problem once more, I most likely won't be as courteous.
