I brought a Redmi K20 Pro in China (I got it from a official Xiaomi store), it have a Snapdragon 855, triple cameras, and a 1080p AMOLED screen. And it only cost ¥3299 (about $450) for the basic model. I think it's the cheapest 855 phone in the market. How come it's so cheap?
Plus, they just announced the Redmi Note 8 Pro which is only ¥1399 and it have quad cameras. How come Xiaomi phones are so cheap?
P.S. I think the international version of the phone is the Mi 6T Pro, it have the exactly same specs and it looks similar.
