Samsung said it has sold more than one million Galaxy Tab devices in less than two months, repeating similar success in smartphone segment when its Galaxy S reached the same figure in less than a week after launch in August.
Samsung's tablet runs on Android 2.2 and has a 1GHz processor, a 7-inch multi-touch screen and dual cameras.
The device was released in the U.S. market in mid-November, almost a month after its release in global markets.
However, it is behind the market leader Apple iPad which sold 1 million units in 30 days in April, and has so far sold more than 8 million devices.
Sold in 3G versions, Galaxy Tab is sold at $399.99 in the US market with a two-year service contract from major wireless providers or at $599.99 without it.
