Samsung this week announced a new flagship smartphone, the long-awaited Galaxy S5, during the Mobile World Congress in Barcelona. The roaring Korean company also announced that it has sold more than 200 million Galaxy S phones since the first version launched in 2010. The Galaxy S line, which operates on Google’s Android system, has been a hugely popular. In sales terms, it is the only family of phones able to compete with Apple’s dominant iPhone. Apple has sold about 410 million iPhones since the first Galaxy S device went on sale. The Galaxy S5 will go on sale globally in mid-April.
