The LG P920 Optimus 3D GSM Smartphone represents a breakthrough in 3D technology that allows users to take and share 3D imagery without glasses. The P920 Optimus was designed with two aims in mind 3D imagery and networking.
For example, the LG P920 has two 5MP camera lenses that take images from slightly different angles. If one looks at the physics of three-dimensional sight, the key factor is that your eyes are set up similarly in that each one sees a view whose angle is slightly different than its mate so that when your brain makes the adjustment, your vision has depth and becomes three dimensional. The same is true of the lenses on the LG P920. As noted, there is only a couple of degrees of difference between the independent images that each lens takes, however, when you overlay them, they become 3D.
The one drawback is that your viewing angle on the 4.3-inch high-resolution screen is limited to about 10 to 15 degrees off to one side. If one goes beyond that point, one loses the impression of 3D imagery. And, because the device is based on the Android operating system, it is closely tied to the Google network and social-networking sites based on the many apps available under Android (estimates are up to 200,000 now), so one can quickly find the app needed to download access to YouTube's 3D network. Using this network, one can share the 3D images one has taken with this state-of-the-art smartphone or one can also share the streaming video one 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, one can share 3D imagery with any DLNA-certified high-definition television or other system, such as a tablet or netbook PC.
The highly innovative LG P920 operates directly with AT&T's and T-Mobile's GSM network as it is a quad-band device, using the 850, 900, 1800 and 1900 MHz GSM WiFi networks offered. Also it recognizes 802.11 b/g/n WiFi networking. These are the standards you will find in most major metropolitan areas so it will recognize and work with public hotspot sites as well as with your older home networking routers that offer 802.11 b/g. The P920 Optimus is supposed to be compatible with WCDMA networking in the 900, 1700, 1900 and 2100 MHz bands through GPRS/Edge. CDMA networks are those offered by Verizon or Sprint.
Feature rich, the device is powered by lithium-ion batteries that drive a 1 GHz dual-core ARM Cortez A9 processor. It comes equipped with 8 GHz of memory standard, as well as 512 MB of RAM memory that is apparently dedicated cache. Since LG makes products that are built to "open" standards one can use any microSD memory card and expand the memory available to up o 32 GB, or more than enough for imagery, videos or simple emails and texting.
The LG P920 operates in 2G mode at a native high-definition resolution of 1080 pixels or in 3G mode at 720 pixel native resolution. 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 one can access any website on the net. It also offers a MIDP emulator.
The speakerphone's fidelity is excellent and it also features voice memo capability, as well as voice commands and dialing. Or, if you are into texting or emailing, you can load the right app and a QWERTY-style keypad will appear that is quite easy to use on the touchscreen, although the keys are too small for true touch-typing. Most Android keyboard apps include predictive keying so they do help speed texting by completing common words for you.
All of this capability comes in a package that is 2.7 inches wide by 0.47 inches thick and 5.1 inches long and which 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 from the lithium-ion battery pack.
