Unlike the Mi6 and previous phones released last year, neither the regular nor the Special Edition of the Mi MIX 2 features a dual-camera setup, meaning it will not be able to compete with other flagships like the Galaxy Note 8 or the upcoming iPhone 8. However, these camera samples are a testament that even though a dual-camera has its advantages, a single camera can be just as capable but that will also depend on the shot you’re taking.

For those wanting to know, the Mi MIX 2 features a 12MP Sony IMX386 camera sensor. The size of the sensor itself is 1/2.9 inches, with the pixel size being measured at 1.25µm. Adequate light will be able to pass through the lens but there is one little detail Xiaomi did not care to mention; the aperture value of the lens. We’ll update you on that front as soon as we get to know more information about the flagship.
