For the first time ever Android now accounts for more than half of all smartphone sales in the U.S. as well as the biggest markets in Europe and Australia, according to an analysis firm Kantar Worldpanel ComTech. Android sales recorded over the last 12 weeks across Europe ranged from 49.6% of all smartphone sales in Italy to 84.1% of all smartphone sales in Spain, TechCrunch reported. Spain saw the largest year-over-year increase of Android sales, up 42.8%. Android sales in the United States declined year-over-year from 57% to 50.2%, however, while sales of iOS¬†devices increased from 28.7% to 37.4%. Despite Apple’s increased legal pressure on Android in Australia, the operating system’s share of the market there grew from 36.4% to 56.9% while iOS fell from 36.9% to 30.5%. As expected, both Research in Motion and Nokia’s old Symbian OS saw sales declines in all markets covered by the study.
