Android and iOS are going from strength to strength and the latest IDC report reveals that the Google and Apple platforms account for about 82 percent of all smartphones sold in Q1 2012.

Android led the way with 89 million units, or 59 percent of the market, while Apple came in second with 35.1 million units, roughly a 23 percent share. Meanwhile RIM’s Blackberry and Symbian saw another bleak quarter. Just over 10 million Symbian phones were shipped in Q1, a drop of 60.6 percent year-on-year. RIM fared somewhat better with 9.7 million units and a drop of 29.7 percent.

Interestingly shipments of Windows Phone and Windows Mobile are not seeing much improvement. Just 3.3 million Windows smartphones shipped in Q1 but we should see the figures improve towards the end of the year. IDC pinned the blame for slow Windows Phone adoption on Nokia and it expects slow growth for Redmond’s mobile OS.
