When Microsoft bought Nokia, it inherited a pretty large feature phone business. But that business has shrunk a lot since the purchase, according to Strategy Analytics, and Microsoft hasn't set the smartphone world on fire either. As a result, Huawei just displaced it as the world's third largest mobile phone vendor by shipping 30.6 million phones, nearly 50 percent more than last year. It now holds a 7 percent market share behind Apple (10 percent) and Samsung (20.5 percent). Microsoft sits in fourth place after selling 27.8 million phones, nearly half the 50.3 million devices it sold last year over the same period.
