AndroidOS.in reported that LG India has officially announced  the launch of two Android smartphones — the world’s first dual-core smarpthone, the LG Optimus 2X, and the world’s thinnest smartphone, the LG Optimus Black. It will be available soon at all retail outlets at a price of INR 30,000 (US $679) and INR 27,000 (US $611) respectively.

The LG Optimus 2X was announced in December and boasts a 4-inch screen, 8GB memory (expandable up to 32GB), dual camera (1.3MP front, 8MP back), full HD video playback and HDMI mirroring, allowing you to output your videos on to the big screen. “The Optimus 2X has an accelerometer, a gyro sensor and a 1500mAh battery.”

The LG Optimus Black was unveiled during the CES and is touted as the world’s thinnest smartphone, coming in at just 9.2mm, tapering down to 6mm. The handset features a 4-inch NOVA display which reduces power consumption by 50% when used indoors, and will ship with Android 2.2 (Froyo) with a view to an Android 2.3 Gingerbread upgrade.

Vishal Chopra, Business Head of Mobile Communication, LG Electronics India said:

“Smart phones have marked the beginning of a new era and undoubtedly 2011 will be the year of smart phones in India. India market is already witnessing a huge demand for these futuristic devices and this demand will tremendously grow in coming years.”

Although initial previews suggested the device would launch with Android 2.2, LG has also confirmed the Optimus 2X will be getting Android 2.3 (Gingerbread), although it is not known whether this will be at launch or via an over-the-air update.
