Samsung retook the lead in the global smartphone market in the first quarter, as gains in emerging market sales helped it overtake Apple, a research group said Wednesday.
IDC said Samsung sold 82.4 million smartphones in the first three months of the year, for a 24.5 percent market share.
Even though the number sold was down seven percent from a year ago, it outpaced Apple, whose iPhone sales slipped slightly from the final quarter of 2014.
Apple held an 18.2 percent market share in early 2015 after selling 61.2 million iPhones.
The figures were impacted by seasonal and other factors. Samsung notably launched its flagship Galaxy S6 and S6 Edge phones at the end of the quarter in April, while Apple iPhone sales dipped compared with the stronger holiday quarter.
In the fourth quarter, Apple and Samsung were virtually tied with around 20 percent of the market each, according to several surveys.
"The challenge made by Apple for the top spot in the fourth quarter returned to a clear lead for Samsung in the first quarter, despite the soaring global demand for the iPhone 6 and 6 Plus," said IDC analyst Anthony Scarsella.
"Samsung's shipments, given that the S6 was not launched into the market for the full quarter, were driven by large volumes into emerging markets and steady demand for its midrange and lower-priced smartphones."
Chinese manufacturer Lenovo was third after completing its acquisition of Motorola from Google. Its 5.6 percent market share placed it ahead of fellow Chinese group Huawei, with 5.0 percent, and South Korea's LG at 4.6 percent.
IDC said the overall global smartphone market grew 16.7 percent from a year earlier, with total shipments of 337 million units.
Apple a 'star'
Strategy Analytics, which released a similar report, said the figures show Apple is a "star" performer because it posted strong sales compared with the same period last year.
"Apple soared 40 percent annually... Apple's new iPhone 6 portfolio is flying off the shelves in China and the United States, its two biggest markets," said Neil Mawston at Strategy Analytics.
Microsoft meanwhile struggled as it took over the Nokia brand of mobile phones, once the world's biggest, according to the research firm.
Figures for Microsoft smartphone sales were not included in the two surveys but the company said it sold 8.6 million Lumia handsets in the quarter, only about half the total of Huawei.
In the broader market, "Microsoft's eight percent global mobile phone market share is sitting near an all-time low," said Ken Hyers at Strategy Analytics.
"Microsoft continues to lose ground in feature phones, while its Lumia smartphone portfolio is in a holding pattern awaiting the launch of new Windows 10 software later this year."
Juniper Research said meanwhile it expects Samsung's performance to improve in the coming months because "the S6 and the S6 Edge have had a better reception than the S5."
Juniper said BlackBerry lost further ground, delivering just 1.5 million handsets in the quarter.
