Nokia is struggling to help Microsoft achieve its goal of becoming the world's third biggest mobile operating system vendor, according to research from IDC.
The firm's research revealed that despite a massive marketing push and the arrival of Nokia's Lumia smartphones, Windows Phone 7 is still losing out to Symbian and BlackBerry devices for market share.
Windows Phone is currently the world's fifth most popular system, accounting for a 3.5 per cent of the market in the second quarter of 2012, while Symbian and BlackBerry held 4.4 and 4.8 per cent share of the market.
Microsoft and Nokia's woes were compounded by the continuing dominance of Apple's iOS and Google's Android platforms. IDC reported that during the quarter Android remained the most widely used OS, holding a 68.1 per cent of the market.
Below it Apple's iOS account was reported as holding a 16.9 per cent, an impressive feat considering it only releases one new iPhone device every year.
IDC predicted that iOS market share will increase later this year once Apple releases its highly anticipated new iPhone model.
"The mobile OS market is now unquestionably a two-horse race due to the dominance of Android and iOS," said Kevin Restivo, senior research analyst with IDC's Worldwide Quarterly Mobile Phone Tracker.
"With much of the world's mobile phone user base still operating feature phones, the smartphone OS market share battle is far from over. There is still room for some mobile OS competitors to gain share, although such efforts will become increasingly difficult as smartphone penetration increases."
Prior to the IDC's release, Nokia's head of UK business sales Adrian Williams told V3 in an exclusive interview that the company planned to boost its market share by targeting business users.
