Hi,
Yes, Mi CC9's software including camera app are 100% Xiaomi, Meitu edition however its calculation is adapted from their newly merged company Meitu, and that's how makes it a selling point.
sorry this is a bit off the topic, so did you buy a Xiaomi CC9 Meitu edition with global Rom? Although I am a Mi fan, I always bought the global version, till when I saw review of Xiaomi CC9 Meitu, it's the very first time I have learnt about Global Rom and seriously considering not to wait for a global version. How do you feel about the phone? Saw the Xiaomi eu for CC9 just released. I am a rookie about all of this, does it give you any problems (assuming you are using the global rom)? Is there no ways banking app and google pay won't work on a global rom xiaomi phone? I know probably I am asking very basic questions here, if anyone can clear some doubts for me, I will be deeply appreciated. Oh, and suggestions on any reliable site where they ship worldwide, great thanks!
