Xiaomi also staked its claim to Apple Inc's crown as the world's third-biggest smartphone maker and most valuable tech start-up unveiled the flagship Mi Note, its challenger to Apple's iPhone 6 Plus.

Chief Executive Lei Jun introduced the Mi Note in Beijing with a breakdown of the large-screen phone's technical features, with multiple comparisons to Apple's equivalent. At 2299 yuan ($371) for a model with 16 gigabytes of memory, the Mi Note will retail for almost two-thirds less than the iPhone 6 Plus.
Xiaomi takes efforts to play down comparisons with Cupertino, California-based Apple, though it is commonly called the 'Apple of China'.
Xiaomi weathered a decline in overall smartphone sales in China last year to see revenue more than double to 74.3 billion yuan (USD 11.99 billion) from 2013.
The company sold more than 61 million handsets in 2014, up 227 percent from a year earlier. In China, the world's biggest smartphone market, overall sales fell 8 percent, according to the Ministry of Industry and Information Technology.
