Samsung has announced that it has sold more than 5 million Galaxy S smartphone handsets since the series' launch in June, according to Reuters. Korea Newswire meanwhile specifies that number includes more than 2 million units in the US and more than 1 million units in Korea.

The Galaxy S is Samsung's best-selling smartphone model; Samsung aims to sell another 5 million Galaxy S handsets in the current quarter. The Android device is available on all major US carriers; though on each it sports a slightly different name (but the Galaxy S moniker is present on each) and set of features. All of them still boast a 4-inch AMOLED touch screen display, 1Ghz Cortex A8 Hummingbird processor, 5-megapixel camera with LED flash and 720p video capture, six-axis sensor for gaming, up to 16GB of internal storage, Bluetooth, GPS, and Wi-Fi.

Samsung, the world's number two phone maker and number four smartphone maker, has a real winner with the Galaxy S. A close friend of mine has the device, and it's definitely one of the best phones I've seen. Its screen alone makes it worth the money. As we emphasize in our latest Buying Guide, however, competition is heating up. Even the Galaxy S is going to be outdated in a few quarters.
