Xiaomi — Privacy concern regarding xiaomi apps

Address:

China

I am a tech savvy person.
I have purchased redmi k20 pro last month.
As my earlier phone was also mi so i was many things were same.
So in the start only i went through all options and discovered a new permissions manager in android 10. I restricted almost all xiomi internal apps and denied permissions to all inbuilt but not required apps.
But still my miui browser automatically assigns location permission to itself.
I disabled it nealry 20 times and even i have stopped mobile data access from both sim cards, even i dnt use wifi still miui browser use 50-60kb data each day, it means it is not switched off. Xiomi is collecting my location data from miui browser and i dnt even use that once since i purchased and always clear all data and cache when i deny permissions.
The same vies for xiomi cleaner, it is a way of tracking people, my all permissions are given to cleaner and i cannot demy them. I mean what is the meaning that i cannot deny the permission, i think we are exposing ourself, next time i wont recommend ever a xiomi phone to anyone.

I cant deny any permission to security app as image attached
