Google’s Android operating system is expected to bypass Nokia’s Symbian this year. Overall sales of smartphones is expected to increase by 49.2% this year, which means that vendors will ship more than 450 million smartphones in 2011, compared to 303.4 million in 2010, according to new statistics from IDC.

Things are happening fast on the market for mobile operating systems right now. Google’s Android is expected to take over first place and push Nokia’s Symbian down to second. Android is expected to have a market share of 39.5% at the end of the year against Symbian’s 20.9%.

In 2015 IDC believes that Symbian has more or less disappeared from the market and Windows Phone will take over second place, ironicly with the help of Nokia.
