Nokia's share of the mobile phone market dropped to 25% in the first quarter of 2011, the lowest for 14 years, down from 30.6% at the same time last year, technology research group Gartner said on Thursday.
"Its market share declined 5.5 percentage points year-on-year, and its share has reached its lowest since 1997," Gartner said in a study.
Nokia had released its own figures on April 21 putting first-quarter market share at 29%, down from 33% in the first quarter of 2010.
Earlier this year, the company announced a radical restructuring to overcome increasingly fierce competition in the smartphone market.
The Finnish company, which had a global market share of 40% as late as 2008, nonetheless remains the mobile industry leader.
It still ranking well ahead of second-place Samsung, which holds 16%, followed by LG in third with 5.6%, Apple in fourth with 3.9% and RIM with 3.0%.
Nokia announced in February that it expected a "period of uncertainty" as it phased out its Symbian platform in favour of a tie-in with Microsoft's Windows Phone operating system for its smartphones.
But Gartner said the Finnish company was still taking a beating in the rapidly growing smartphone sector, pointing out that "Android and Apple's iOS continued to dominate the smartphone operating system wars."
