LG (066570) has found success with its new Optimus G Pro phablet. The device launched in South Korea in late February and has already sold more than half a million units in a mere 40 days. The Optimus G Pro has seen considerably more success than the original Optimus G smartphone, which reached sales of 1 million units in four months on the market in South Korea, Japan, Canada and the United States. The company’s latest handset, which looks strikingly similar to Samsung’s (005930) Galaxy Note II, is equipped with a 5.5-inch full HD 1080p display, a 1.7GHz quad core Snapdragon 600 processor and a 13-megapixel rear-facing camera. The Optimus G Pro also includes a microSD slot, NFC, LTE connectivity, a 3,140 mAh battery and Android 4.1.2 Jelly Bean. LG previously announced that the smartphone will be available in the U.S. later this year.
