Samsung and Nokia responsible for driving the operating systems forward.
It seems there's no stopping Google's Android juggernaut, as the OS achieved a first in Q3 2013 by passing an 80 per cent share of all smartphone shipments, reaching 81 per cent – 211.6 million units.
Samsung, meanwhile, accounted for 39.9 per cent of Android shipments during the period, while other OEMs secured a single digit share, according to IDC.
The data says the overall smartphone market still achieved a 39.9 per cent year-on-year growth despite high adoption levels in developed markets.
Meanwhile, Windows Phone rose by a huge 156 per cent year-on-year, though its share is still under five per cent, which Microsoft will be hoping to change with its Nokia acquisition.
The Finnish OEM accounted for a massive 93.2 per cent of all WinPho-powered shipments over the quarter.
Smartphone average selling prices (ASPs) have fallen 12.5 per cent to $317, while another trend has been the arrival of phablets sporting five to seven-inch screens. The latter usually come with a higher ASP of $443 due to pricier components, but the cost was still down 22.8 per cent from $573 in 2012.
Ramon Llamas, research manager with IDC's Mobile Phone team, said: "Android and Windows Phone continued to make significant strides in the third quarter. Despite their differences in market share, they both have one important factor behind their success: price.
"Both platforms have a selection of devices available at prices low enough to be affordable to the mass market, and it is the mass market that is driving the entire market forward."
Ryan Reith, program director with IDC's Worldwide Quarterly Mobile Phone Tracker, added: "Almost all successful Android vendors have added one or more 5-7-inch phablets to their product portfolios.
"And Nokia's recent announcement of the Lumia 1320 and 1520 put them in the category as well. In 3Q13, phablet shipments accounted for 21 per cent of the smartphone market, up from just three per cent a year ago. We believe the absence of a large-screen device may have contributed to Apple's inability to grow share in the third quarter."
As for BlackBerry, the OS achieved the largest year-on-year decline as BB10 failed to bring in the business hoped for. The company recently fired its CEO and secured a $1 billion investment to move forward, so we'll see if the new strategy makes a difference.
