Windows Phone was more popular than Symbian during a three month period ending February 19th, according to research firm Kantar Worldpanel. The company found that Windows Phone made up 2.5% of all phone sales during that time period while Nokia’s Symbian operating system had just a 2.4% share of phone sales. Not surprisingly, Nokia’s Lumia 800 was the catalyst for Windows Phone’s success; the handset was responsible for 87% of all Windows Phone sales in Europe. Symbian’s smartphone share was 12.4% during the same period a year ago. “The fact that Windows Phone sales have overtaken Symbian based on one handset is encouraging,” Kantar analyst Dominic Sunnebo said. “However, Nokia will need to expand the range quickly in order to keep up with the slew of next generation competitor products being launched in quarter two.” Nokia recently announced entry-level Lumia 610 device as well as a new flagship phone called the Lumia 900, which will be available in Europe later this year.
