So since around when the NEW 3DS XL launched, I've been having troubles with the "super stable 3D". After reading around the internet, other people have been experiencing the same thing. I've read all sorts of stuff like wearing glasses messes with it (I wear glasses), to the lighting in the room, and even people sending them in for repair.

I'm just here to say that the Nintendo site says it shouldn't need calibration, so I selected restore default setting in the calibrate super stable 3D settings menu. Now it works fine for me. Just figured I'd spread the word, in case anyone else was having trouble. It seems to be a common complaint with the system. It may be common knowledge by now, but figured DP could use helpful info like this.

Hope this helps
