For Samsung Electronics, the bad news in Asia isn't confined to China. The Korean company has lost its No. 1 spot in the world's largest smartphone market, research firm Canalys said on Monday. Pushing aside Samsung in China is Xiaomi, a young, Beijing-based company that has the world's fastest-growing smartphone brand. Samsung, the longtime leader in China, slumped to a 12% market share, lagging Xiaomi's 14%. Samsung's longtime dominance in the other giant Asian market -- India -- is under threat, too. Micromax Informatics, a company from the Delhi satellite city of Gurgaon that started selling phones only in 2008, is now the top brand in India.
