LG is planning to bring out in 2012 an updated and slimmer version of the LG Optimus 3D, one of the developers of the 3D handset told Pocket-lint early this week.

Henry Noh, who was on the development team for the LG Optimus 3D, explained that the current build of LG Optimus 3D isn’t the “ slimmest and sexiest phone on the street” and that they want to make it slimmer.

LG’s main reason for enhancing this 3D-capable phone—aside from providing improved specs—is to keep in line with competitors for a slimmer phone chassis next year. Thus, LG intends to produce slimmer and sexier–if possible, the thinnest–phones that the company hopes to launch next year.

Noh also noted the growing trend among smartphones these days. “These days, all the phones look the same. They have a huge screen–4.3-inches is normal these days–and next year they’re moving even larger. And they have a fixed number of touch buttons. They’re the same thickness. They have the same camera. And even the same OS. It’s so boring,” he said.

In the midst of that “boring” trend in smartphones, Noh hopes and believes that a slimmer LG Optimus 3D 2 will stand out, especially if the build and design is competitive.

Noh also believes that a huge portion of the population won’t notice the difference in thickness between a 6-millimeter non-3D phone and a 7-millimeter 3D phone. LG is hoping to create 3D-capable smartphones that don’t necessarily have to be noticeably thicker than most thin smartphones. The 3D-capability, Noh predicts, “is going to be differentiating factor that comes for free to the user.”

LG has not yet announced any definitive word about the specs for the upcoming LG Optimus 3D 2. For now, all we know is that LG plans for the device to be slimmer than the current LG Optimus 3D.

Which phone are you buying next year? A slimmer 3D-capable smartphone, or a slimmer non-3D smartphone?
