The LG Optimus 2X is a smartphone designed and manufactured by LG Electronics. The Optimus 2X is the world's first smartphone with a dual-core processor and third phone in the LG Optimus-Android series. 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]The phone holds the record for the longest update holdout, taking 16 months to receive a firmware update from Android 2.2 to 2.3.[5]


The LG Optimus 2X holds the Guinness World Record for being the first mobile phone to use a dual-core processor.[6] It is also the first smartphone to feature the Nvidia Tegra 2, a dual-core processor clocked at 1 GHz or 1.2 Ghz. 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.


The LG Optimus 2X has a 4-inch LCD IPS capacitive touch-screen, displaying 16.7 million colours at 480×800 pixels.[7]

Storage & Memory[edit]

The LG Optimus 2X has a card slot for additional memory. It supports a microSD card of up to 32 GB capacity. It has up to 8 GB of internal memory storage and 512 MB RAM (384 MB available) or 1 GB RAM (496 MB available).[7]


An 8-megapixel camera is included on the Optimus 2X and is capable of 3264x2448 pixels. The camera includes auto focus and a LED flash. A secondary front-facing 1.3-megapixel camera is located on the front of the device but is incapable of making use of the LED flash on the backside of the phone. The primary camera is capable of video recording of 1080p at 24 fps, or 720p at 30 fps.[7]


The aftermarket Android firmware Cyanogenmod has been developed for the Optimus 2X. Official CyanogenMod support was added in CyanogenMod 7.1.[8]


LG previewed the Optimus 2X under the device's internal development name, "LG Star", at CES 2011.[9]
