Ok thanks I will try..I'm happy with 8.9 20. Best miui10 camera quality in my opinion. Don't need api2 no more.
In comparison with my wife's mi note 3 with MIUI 9 8.4.26 it's first MIUI 10 which can keep up with MIUI 9, especially in night scene. HDR is even better now.
You have to delete first cache and settings in camera app.
