Just 2 weeks ago Xiaomi has launched Mi 5s and Mi 5S Plus and here we got a picture of alleged Xiaomi Mi 6. Someone took the picture of this unofficial Xiaomi device from front and back. By looking at the front it has a 2.5D glass and a fingerprint sensor which will also work as a home button.
At the back of this unofficial Mi 6 looks like they gave it a matt metal finish. And a Mi logo. There is only 1 camera with dual tone flash on the top right corner.
The picture looks early stage of development. At this time there are no rumours regarding specifications.
