New figures from research firm Kantar Worldpanel ComTech reveal that not only is Google's Android dominating the U.S. smartphone market, it is also leading the charge in five other key countries.

Great Britain, Germany, France, Spain and Japan have all succumbed to Android's allure, the study found. Of the eight markets analyzed, Android was not the leading smartphone OS in only two – Italy, where Nokia's Symbian still holds the lion's share, and Australia, where Apple's iOS has a slight lead over Android.

However, Android isn't the only smartphone OS currently rising through the ranks. As Kantar's report showed, iOS and Samsung's Bada have also experienced growth in several markets.

Meanwhile, Symbian and Research In Motion's BlackBerry OS have struggled in recent months against their competitors. Symbian, in particular, saw its share drop in each of the studied markets.

Overall, the global smartphone market is expected to continue its meteoric increase. According to a recent report from IDC, the market is forecast to grow 55 percent this year over 2010, with Android leading the way.
