The main sensor is IMX989, which is known as 1-inch sensor and it has best quality.
For ultra-wide and telephoto, it uses 1/2" IMX586.
When using default (Xiaomi) camera app, it uses IMX989 for wide, IMX 586 for ultra wide, telephoto, and macro.
This is normal. Nothing to be special.
But the problem starts when you're using 3rd party applications.
If application uses Android standard camera API, they will not utilize the main sensor.
Instead of a huge 1-inch IMX989, they will use IMX586 on the ultra wide.
You will get normal wide focal length (NOT ultra wide), but It will be noisier, less dynamic range, less resolution.
Maybe ultra wide sensor has two mode - full sensor readout for ultra wide, and pixel binning/cropping for macro and normal focal length.
This can be disappointment for some people, and huge minus for some nerdy professionals who using 3rd party apps like Filmic Pro.
You can test this by blocking MIDDLE lens on the back.
As far as I checked, Lightroom, Instagram, MotionCam, was not able to use Main sensor.
UPDATE : after clean installation of MIUI 13.0.7 with factory reset, problems are now fixed.
