Engadget took a look at the device while on a trip to Taiwan and had this to say about its 3D capabilities:
The 4.2-inch qHD (960 x 540 pixel) glasses-free 3D LCD is just spectacular, with excellent colors, brightness, and contrast as well as decent viewing angles. On the imaging front, the Aquos trumps the EVO 3D with twin 8 megapixel autofocus cameras with flash and autofocus assist light. But just like Sprint's flagship, it takes 3D pictures at 2 megapixels (in MPO format only) and captures 3D video in 720p at 30 fps, with the left and right frames being squeezed into a single 1280x720 pixel H264 frame
...Sounds like the future of 3D phones may be brighter than we'd previously imagined. Take a look at the phone in action below:
Sadly, no word yet on when this phone will be released to the rest of the world.
