LG debuted the Optimus 2X on December 16, 2010 and the device first became available to consumers in South Korea in January 2011.[2] It was also launched in Singapore on March 3, 2011. The Optimus 2X runs the Android 2.3 software version since the upgrade in November 2011,[3] but the latest offering is Android 4.0.[4]

Holds the record for longest update holdout, taking 16 months to go from Android 2.2 to 2.3.[5]

It also has a micro HDMI port and an 8-megapixel camera. Through the micro HDMI port the Optimus 2X is capable of HD playback when connected to an HD device, such as an HDTV.
