[CES 2011] You might know of it as the LG B, but the phone has now gone official under the name of the Optimus Black. This phone is LG’s latest flagship Android phone and offers a 4-inch NOVA display, promising to be bright (700 nits) and energy efficient. While most slim phones tend to have less-impressive battery life, this phone features a 1,500mAh battery despite being just 9.2mm slim and tapers down to 6mm. Another feature that you rarely see on phones is the 2-megapixel front-facing camera. The phone will initially ship with Android 2.2 and LG’s Optimus UI 2.0, though it’ll receive the Android 2.3 Gingerbread update somewhere down the line. Expect the LG Optimus Black to roll out globally in the first half of 2011.
