The LG P920 Optimus 3D GSM smartphone represents a breakthrough in 3D technology that allows users to take and share 3D images without glasses. The P920 Optimus was designed with two goals in mind: networking and 3D imaging.
For example, the LG P920 has two 5MP camera lenses that take pictures from slightly different angles. If you look at the physics of three-dimensional vision, the key factor is that your eyes are similarly configured in the sense that each sees a view whose angle is slightly different from its partner’s, so that when your brain does the adjustment, your vision has depth and becomes three-dimensional. The same goes for the lenses of the LG P920. As noted, there’s only a couple of degrees of difference between the independent images each lens takes; however, when you overlay them, they become 3D.
The only drawback is that your viewing angle on the 4.3-inch high-resolution screen is limited to about 10 to 15 degrees to the side. If one goes beyond that point, one loses the impression of 3D images. And, because the device is based on the Android operating system, it is closely related to Google’s network and social networking sites based on the many apps available on Android (estimates are up to 200,000 now), so one can quickly find the application. necessary to download access to the YouTube 3D network. Using this network, one can share the 3D images that he has taken with this state-of-the-art smartphone or he can also share the video stream that he has taken.
The LG P920 includes autofocus and low-light capability due to its built-in LED flash. And since the device includes a built-in HDMI port, 3D images can be shared with any DLNA-certified HDTV or other system, such as a tablet or netbook.
The highly innovative LG P920 operates directly on the AT&T and T-Mobile GSM network as it is a quad-band device, using the 850, 900, 1800 and 1900 MHz GSM Wi-Fi networks on offer. It also recognizes WiFi 802.11 b/g/n networks. These are the standards you’ll find in most major metropolitan areas, so it will recognize and work with public hotspot sites as well as your older home network routers that offer 802.11 b/g. The P920 Optimus is supposed to support WCDMA networks in the 900, 1700, 1900 and 2100 MHz bands via GPRS/Edge. CDMA networks are those offered by Verizon or Sprint.
Feature-rich, the device is powered by lithium-ion batteries that drive a 1GHz dual-core ARM Cortez A9 processor. It comes equipped with 8GHz of standard memory, as well as 512MB of RAM that is apparently dedicated cache. Since LG makes products that are built to “open” standards, you can use any microSD memory card and expand the available memory up to 32GB, or more than enough for pictures, videos, or simple email and text messages.
The LG P920 works in 2G mode with a native HD resolution of 1080 pixels or in 3G mode with a native resolution of 720 pixels. It is, perhaps, one of the most capable smartphones on the market, offering not only a document viewer and editor, but also support for standard Flash and Java sites. This means that one can access any website on the net. It also offers a MIDP emulator.
Speakerphone fidelity is excellent and there is also voice memo capability as well as voice commands and dialing. Or, if you like texting or emailing, you can load up the right app and you’ll be presented with a QWERTY-style keyboard that’s easy enough to use on the touchscreen, though the keys are too small for touch typing. Most Android keyboard apps include predictive keys, so they help speed up texting by completing common words for you.
All this capacity comes in a package that measures 2.7 inches wide by 0.47 inches thick and 5.1 inches long and weighs 5.92 ounces. It is lightweight and offers up to 13 hours of talk time in 2G mode and 9 hours in 3G mode. Standby time is 450 with the lithium-ion battery pack.
