IDC is out with its latest report that covers the top six smartphone operating systems by shipments and market share during Q3 2012. In the study, IDC found Android on nearly 75 percent of all smartphones shipped during the quarter, giving Android 136 million units of the 181.1 million total smartphones shipped during Q3 2012. That accounts for 91.5-percent year-over-year growth, beating out 57.3- percent year-over-year growth for Apple, and an average market growth of 46.4-percent. Apple shipped 26.9 million iPhones, in comparison, giving the company 14.9-percent of the market in the third quarter. Samsung is once again the top Android vendor:

Android, having topped the 100 million unit mark last quarter, reached a new record level in a single quarter. By comparison, Android’s total volumes for the quarter were greater than the total number of smartphones shipped in 2007, the year that Android was officially announced. Samsung once again led all vendors in this space, but saw its market share decline as numerous smaller vendors increased their production.

iOS was a distant second place to Android, but was the only other mobile operating system to amass double-digit market share for the quarter. The late quarter launch of the iPhone 5 and lower prices on older models prevented total shipment volumes from slipping to 3Q11 levels. But without a splashy new OS-driven feature like Siri in 2011 and FaceTime in 2010, the iPhone 5 relied on its larger, but not wider, screen and LTE connectivity to drive growth.
