Ah, the LG Optimus 3D! The first phone capable of displaying 3D content glasses-free, a device we got to hold and play with at MWC. Also something that we'll be telling stories about to our grandchildren one day. Or maybe not. Anyway, currently glasses-free 3D on phones is more or less of a mystery even for more advanced folks. That's why in the craziness called Mobile World Congress we stole a second with the dual-lens 5 megapixel camera on the Optimus 3D to give you a basic idea of how shooting videos and images looks like. Pretty simple, it turns out, just like everything great in life. The 3D switch allows you to select between traditional 2D and the new 3D shot mode. Photos can then be viewed right on the screen, which uses the parallax barrier to give you the depth effect. Check out the camera interface and all the details in a quick video demo below!
