Windows Phone Becomes Fastest Growing mobile OS in the World

According to the latest survey by Canalys, Windows Phone of Microsoft is the fastest-growing OS in the world in Q2 of 2012 with an increase of 227% devices in Q2 of 2011. Sales too increased to 5.1 million worldwide.
Android however, retained the top-spot (in terms of market-share) and actually increased its lead by 110% over the last quarter. The sales now amount to 107.8 million. This is huge because the number of smartphones in the same quarter a year ago amounted to 107.7 million.
Apple iPhone’s sales increased by 5.7 million to 26 million in Q2. Market-share declined though by 2.5% to 16.4%.
Symbian’s sales dropped by 64.6 percent to a market-share of only 4.1% and sales of only 6.4 million while those of Bada increased by 5.1% to 3.3 million. If sales for Symbian continue to drop at this pace, they’ll be below Bada in the near future.
Windows Phone 7 will probably take over Symbian in terms of sales in a quarter perhaps.
But it must be noted that the sales of Windows Phone devices aren’t mind-blowing considering the millions of dollars spent advertising campaigns by Nokia, Microsoft and AT&T.
BlackBerry experienced a 4 million unit decline in sales. There market-share is now only 5.4% compared to the 11.6% they had a year ago.
China leads the phone market in the world thanks to a market-share of 27%. USA is behind them with a market-share of 16%. Android is the most-preferred OS in China and dominates with a market-share of 81%.
