Another day, another chart showing Android's spectacular growth. What you see above is Gartner's numbers for the first quarter of 2011. And in those three months, some 36.2 million Android devices were sold worldwide, for a 36 percent share in the period. Second highest was Symbian, at 27.5 million, and iOS devices totaled 16.9 million devices. BlackBerry was at 13 million, and Microsoft (Windows Phone) a meager 3.6 million. HP's webOS was relegated to the "Other" category.

Compared to Gartner's Q1 2010 numbers, Android increased nearly 600 percent for total sales, and increased its global market share by 26 percentage points. Apple's iOS, on the other hand, doubled its unit sales but only increased its market share by 1.5 percentage points.

Overall, some 428 million mobile devices were sold in the first quarter of the year, up 19 percent from the same period a year ago.
