The Optimus One with Google is a entry-level series touch-screen smartphones manufactured by LG Electronics, Inc. Initially released running the Android 2.2 Froyo software stack, LG plans to release software to upgrade the many variants 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 seven variants, with at least one more on the way. The Optimus One line is the first LG smartphone line to sell more than 1 million units. As of December 10, 2010 (2010 -12-10)^[update] 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.
