Agreed . That should be first course of action to resolve most of the issues

I know miui not allow this but camera result and some other problems in latest miui 10 and i don't like miui 10 so i want to go old version which has best camera performance and also battery backup.
I don't know why miui team decrease performance of famous Redmi series.
If someone know then give me Process i want to go back in miui old version.
