Samsung has sold 10 million Galaxy tabs, since it was launched five months ago in April 2011. Sales have doubled from five million in just eight weeks, said the company in a statement.

The Galaxy tab was launched in United States in August this year. The device is sold through Verizon, Sprint, AT&T, T-Mobile, and U.S. Cellular. Prices start from around $199 with a two-year contract. The tabs come in a Wifi-only flavor as well.

This sales come in the wake of the country’s ban from selling these devices in a handful of countries as part of an ongoing lawsuit with Apple. In the U.S., the lawsuit is currently under scrutiny by the United States International Trade Commission (USITC). “Instead of pursuing independent product development, Samsung has chosen to slavishly copy Apple’s innovative technology, distinctive user interfaces, and elegant and distinctive product and packaging design, in violation of Apple’s valuable intellectual property rights,” Apple alleges in the lawsuit.

Samsung and Apple were hardware partners, before relationships went south. Once upon a time (way back in 1999), Apple had even invested $100 million in Samsung Electronics to further expand Samsung’s TFT-LCD flat-panel display production capacity. The investment was part of Apple’s strategy to ensure an adequate supply of TFT-LCD displays to meet the growing demand for Apple products.
