Lenovo is primarily known as a Chinese PC company, but its smartphone sales have been exploding in China, with twice as many smartphone sales as Apple (NASDAQ:AAPL) in Q3 of 2012. It now holds about 15% of the smartphone market share in China, well ahead of Apple's 7%, and gaining quickly on the market share leader Samsung, which has 17%. In this video, Motley Fool research analyst Lyons George discusses how this isn't just a problem for the two smartphone titans in terms of market share erosion. Lenovo is willing to sell its phones to grab market share -- even at a loss -- something that may be very damaging to the big guys' bottom line.
