Samsung Electronics Co Ltd reclaimed its crown as the world's biggest smartphone maker from Apple in the first quarter, cornering a fifth of overall global shipments.

China's Xiaomi Corp rounded out the top three positions with its best quarterly performance ever as shipments surged 62% to 49 million phones and its market share rose to 14%, market research firm Canalys said.

Overall, global shipments surged 27% to 347 million units in the first quarter as the Chinese economy opened up after the pandemic and a swift vaccine rollout in the United States raised hopes of an economic recovery.

South Korea's Samsung shipped 76.5 million smartphones in the quarter to grab a 22% share of the market, Canalys said. The company on Thursday reported a 66% surge in quarterly profit in its mobiles business, thanks to robust sales of its flagship Galaxy S21 smartphone series.

Canalys said Apple shipped 52.4 million iPhones in the January-March period, falling to the second spot with a 15% share of the market.

Apple still grabbed record market share in the United States, China, India and Japan, Counterpoint analyst Varun Mishra said, adding that the iPhone Pro Max was a top seller in the United States.

Smartphone sales have surged over the past year as people stayed and worked from home. But the shopping frenzy has fuelled a global shortage in semiconductor chips that has roiled industries including autos and large appliances.

"Supply of critical components, such as chipsets, has quickly become a major concern, and will hinder smartphone shipments in the coming quarters," Canalys analyst Ben Stanton said.

Apple said on Wednesday that the chip shortage could cost the company $3 billion to $4 billion in revenue in the April-June quarter, affecting primarily iPads and Macbooks.

March-quarter smartphone shipments for China's Oppo and Vivo brands also surged, Canalys said. But Huawei, the former No. 1 that remains shackled by U.S. sanctions, took only seventh place after selling its Honor brand last year.
