HTC outperformed by Nokia, Samsung -

Ex-Microsoft man, Stephen Elop, who has the Swing Factor, has managed to make Nokia the largest of any companies shipping Redmond's operating systems for smartphones.

Nokia managed to grow its shipments 36 percent in the fourth quarter of 2011 from the third, reaching 2.7 million units in total. The Microsoft-backed former rubber-boot maker outpaced other companies, overtaking HTC, to become the largest Microsoft OS vendor for the last quarter of 2011.

Strategy Analytics, which conducted the survey, said that although Microsoft smartphone shipments are tiny compared to the competition, they are showing "tentative signs of growth".

Thanks largely to the Lumia, Nokia managed to ship 0.9 million units for Q4 2011. Others, altogether, reached 1.8 million shipments in the quarter, putting Nokia at roughly half of all Microsoft smartphones shipped.

Strategy Analytics director Tom King said that Nokia had done well to capture market share from HTC. HTC would be right to feel challenged, King said, because it is also losing ground to Samsung in the Android market.

"HTC is now at risk of being caught in a pincer movement between two giants of Samsung in Android and Nokia in Microsoft," King said, "and HTC must move with urgency to address the problem".
