I've yet to find the perfect phone, but Xiaomi's Mi Mix 3 comes closer than anything I've used in years.
Xiaomi's flagship phone is almost the perfect phone, and the company's making it available in even more countries. The bad news is the US isn't one of them.
The Mi Mix 3 is absolutely gorgeous and its sliding mechanism makes a satisfying click. The camera takes great shots as well and battery life is fantastic.
The phone can be a fingerprint magnet, it's not waterproof and the front cameras don't do secure 3D face unlocking.
