Those of you who have seen or posted threads asking why certain 3DS models seem to have an issue with the top screen being darker or having a yellowish tint will be interested in this. Apparently, Nintendo has acknowledged the difference in screen quality between older and newer 3DS models, but is adamant that the issue is neither a defect nor in need of repair. You can read the story here... http://www.zeldainformer.com/news/comments/nintendo-on-3ds-screen-controversy-this-is-within-manufacturing-specificati My used 3DS has log data from March 2011, so it's one of the older models. In the picture shown in the link, the 3DS with the yellower screen looks a lot like my 3DS when using power-save mode. Personally, since I use power-save mode 24/7, this doesn't bother me at all personally. But what do you guys think? Discuss.
