# LG Optimus One

The LG Optimus One is an entry-level series of touch-screen smartphones manufactured by LG Electronics, Inc. It was released running the Android 2.2 Froyo, and later LG released software to upgrade it to Android 2.3 Gingerbread. Although the basic physical form factor of each variant is the same, the variants have differences in hard button shape and layout, the form of the metal side bezel and the user interfaces added by LG or various carriers. Versions of the Optimus One exist that operate on various frequency bands and either GSM or CDMA-based network protocols. They may also feature one or more variations in hardware, such as a faster processor, the addition of a physical keyboard, a modem with higher theoretical speeds, or a better digital camera.
Since sales first began in mid-November 2010, LG has released ten variants, though some differ very little from others. The Optimus One line is the first LG smartphone line to sell more than 1 million units. As of December 10, 2010 more than 2 million units have been sold worldwide, with 1.3 million units sold in North America, 450,000 units sold in South Korea, 200,000 units sold in Europe and 50,000 units sold in Asia and the CIS.

## Variants

Because of the different technologies used by wireless operators in the United States, many variants of the LG Optimus One exist, usually replacing the word "One" with a single letter representing the carrier. For example, the LG Optimus M was offered exclusively by MetroPCS, while the LG Optimus T was only available at T-Mobile USA.

### Primary configuration

The Optimus One P500 was the first version offered for sale, with sales beginning in South Korea in mid-November 2010. This GSM version of the phone is sold by wireless communications service providers in Asia, Europe and Canada.
In Canada, the LG Optimus One (P500h) is sold by Telus Mobility since December 2010 and its brand Koodo Mobile since February 2011, with UMTS frequency at 850, 1900, and 2100 MHz.
In Turkey, a matte black variant is sold as the LG Optimus One (P503).
Walmart Family Mobile released the LG Optimus One (P504) in charcoal in September 2011.

### Carrier variants

* LG Optimus S: The LG Optimus S was initially released by Sprint in charcoal gray and purple on October 31, 2010. It includes the Sprint ID graphical user interface (GUI) and CDMA network connectivity. While it is similar to the Optimus One, the Optimus S features minor hardware differences. This device has four distinct hard keys and a metal accent that covers the top of the device and one-third of each side. The 3.5mm TRS connector, the power button and the volume buttons are all incorporated into the metal band. There are also two hard keys on the right side of the phone. One button activates the voice dialer and another activates the camera. The "Menu" and "Home" buttons on the S are transposed as compared to all other variants of the Optimus One.
