Android's Smartphone Market Share "Unshakable" at 75 Percent
Between the two, Google and Apple own more than 92 percent of the smartphone market. All other players are left fighting for scraps, and it's a dogfight between BlackBerry (3 percent) and Microsoft (2.9 percent) as to which gets to come in a distant third place.

"There are two clear leaders in the OS market and Android’s dominance in the OS market is unshakable," said Anshul Gupta, principal research analyst at Gartner. "With new OSs coming to market such as Tizen, Firefox and Jolla we expect some market share to be eroded but not enough to question Android’s volume leadership."
Overall mobile shipments totaled 426 million units in the first quarter of 2013, up 0.7 percent from the same period a year prior. Of those, 210 million were smartphones, which represents a 42.9 percent increase from a year ago. Samsung was once again the busiest body in the smartphone space, shipping over 100.6 million units to claim a 23.6 percent share of the market.
