The Mi Mix 3 also comes in a 5G version touted by Xiaomi as the world's first such commercially available phone, though it's not expected to launch till the first quarter of next year. This might disappoint fans who were excited by a leak showing 5G support on the phone last month, but the delay won't matter too much -- even if 5G capabilities were available on it now, you won't be able to use it until network buildouts are completed. This is true even in Xiaomi's home country, even though China is at the forefront of 5G development.

In terms of design, the Mi Mix 3 takes a step closer to losing its signature chin. Mi Mix phones used to have a bottom bezel -- now reduced to 4.46 mm -- that housed the selfie camera. But the cameras have now been moved to a magnetic slider on the phone. You can slide the entire screen downwards to answer calls or customize it to launch different functions. The feature is similar to ones seen in the recent Oppo Find X and Huawei's Honor Magic 2, which will be launched on Oct. 31.
