All editors agreed that the phones are extremely finicky about their positioning; you have to keep each one directly in front of your face in order for you to see the 3D effect. If you move the phone, even slightly, the 3D effect fades.

The HTC EVO 3D and the LG Optimus 3D both have 3D cameras and camcorders, so you can capture 3D photos and video and play them back on a 3D TV or on the phone itself.

To see which phone had the superior camera, the PCWorld Labs conducted a variation of its regular testing methodology for stand-alone point-and-shoot cameras. We assembled a still-life scene with a variety of objects placed at different distances from the camera. If you look at the image to the left, you'll see markers that indicate the distance the object is from the camera. This setup gave us a nice range of depth so that we could judge how effective the 3D was. To make things more interesting, we also included a stand-alone 3D camera, the , in our subjective tests to see how the phones stacked up.

We affixed each device to a tripod so that we could take all photos from the same distance. We captured all images using full auto mode, with no post-processing. A panel of five editors viewed the photos from each device on a Panasonic TC-P50ST30 3D HDTV, and scored the images for their color, sharpness, 3D depth, and overall 3D experience. The editors gave each category a word score (Excellent, Very Good, Good, Fair, or Poor), and then we averaged out those scores.
