Xiaomi's Mi-Mix series has always pushed the boundaries of the phone's screens and form factors, from the original model that triggered the war on the bezel to the sliding, no-dash, last year's Mi-Mix 3 model , Waterfall displays with extremely curved edges set new standards with Mi Mix Alpha.
The display on the Alpha display swings completely around the unit until it hits the camera module on the other side. The effect is an almost entirely screen-based phone with status icons such as network signal and battery charge displayed on its side. A selfie camera is not required. Just flip the phone over and use the back of the display as a viewfinder.
The Mix Alpha uses the new 108-megapixel camera sensor from Samsung, which was developed jointly with Xiaomi. As with other newer high-resolution Samsung sensors, the pixels are combined into 2×2 squares for better light sensitivity in low light conditions. In this case, images are generated at 27 megapixels. We'll see how this works in practice, but the 1 / 1.33-inch sensor is unusually large for a phone and should give the Mix Alpha a lot of light collection capability.
Xiaomi describes the Mix Alpha as a "concept smartphone" and has yet to reveal whether it is actually released or even mass-produced. On the other hand, CEO Lei Jun is currently on stage, so we have to see. The original Mi-Mix was also awarded the label "concept", but came on the market.
We will update this post with more information as soon as Xiaomi announces it.
