In May 2010 only 27 percent of the mobile consumers in the UK used smartphones. Now this number has grown nearly twice and made up 42 percent.

This increase in smartphone popularity has created a competitive landscape for the most popular mobile operating systems, namely Symbian, Apple’s iOS and Google’s Android.

Only a year ago Symbian was the most popular OS in the UK, but now the situation has changed – Apple’s iOS has managed to overtake Nokia’s Symbian and to take 27.1 percent market share, so now iOS is the top platform in the UK with almost 6 million users.

Android, which is considered to be the best and the most popular smartphone in the world, is only the second in the UK with 26.7 percent market share. However, this number is also great for Google’s OS for now, since its market share only a year ago was really tiny, and now it has grown by (attention!) 634 percent!

Symbian is only the third now, and its market share is only 22.5 percent (10 percent less than in May 2010). The number of Symbian smartphone users has also decreased to 4.5 million.

RIM is on the fourth place with 59 percent increase, and Microsoft’s platform is the fifth with 32 percent decrease.
