The P9, Huawei's flagship device, is the first result of the tie-up between the world's third biggest smartphone maker and Leica Camera AG, a 102-year-old firm whose cameras have shot some of the most famous images in the history of photography.
Huawei said consumers were increasingly focused on the photographic capability of smartphones, and the company wanted to partner the best in the field.
"Leica is the leading, premium iconic brand in cameras," Richard Yu, chief executive of Huawei Consumer Business Group, said at a launch event in London.
The dual-lens 12 megapixel camera on the rear of the device separately captures monochrome and colour images, and combines them to create more detail, depth and brighter colours than rival single lens cameras, he said.
Leica said the collaboration went far beyond just branding, with the two companies working together on lenses and image processing technology.
"A lot of people would like to have our red dot and put it on their product," said Leica's Chief Executive Oliver Kaltner.
"This is not what we are. We are the centre of optical excellence worldwide, and we should take advantage of that knowledge."
Photography dominated the event as professional snappers including Mary McCartney and David Guttenfelder from National Geographic took to the stage to show what the device could do.
The P9 will be available in 29 countries from April 16, priced from EUR 599 ($684 or roughly Rs. 45,500), the company said.
Roberta Cozza, research director at Gartner, said Huawei's technology was "great" but the company needed to innovate in areas like software to become a trend setter.
"They need users to pick the brand or upgrade within the brand from maybe a mid-tier, and the more they go into the premium end, the more they have to stand out as an overall experience," she said.
Huawei, which leads the pack of Chinese smartphone makers, however is confident the P9 will help it gain ground on market leader in terms of volume Samsung and second-placed Apple.
It became the first Chinese company to ship more than 100 million smartphones, recording a 44 percent jump in devices to 108 million last year.
"We have the chance to be number two within two to three years, with market share of over 20 percent," Yu said. "We have the chance to be number one in less than five years."
