The Smartphone war has turned into a two horse race as Android and iOS continue to grow their international hold on the mobile market while competing operating systems such as BlackBerry OS and Symbian continue to fall from relevancy. Android reigns supreme in IDC’s latest look at International Smartphone sales with a 59 percent hold on the market in Q1 of 2012. Compared to a year ago, Google’s mobile OS is up about 26 percentage points. Pretty amazing growth.
