Xiaomi or Redmi phone too much slow after update? try this fix

I was using Redmi 7 with stock rom of Android 9. It was all rounder with good battery backup. Everything was well until i updated it to Android 10. Now the phone is slow like 1990s device. Just wanteyto rollback to Android 9 but before that i tried some settings which worked and now device is usable if not worse.

Solution is to disable MIUI optimizations. Follow below steps to achieve the same -

- Enable developer mode. Go to settings -> About Phone -> All specs -> tap on MIUI version 5+ times. This will enable developer mode.

- Go to Settings -> Additional Settings -> Developer options -> almost at bottom -> Disable MIUI optimizations.

- Or search MIUI in settings. It will show the entry from there.

Its recommended to enable OEM unlocking option because it comes critically helpful to recover device. Example forgetting lock pattern, pin, password, upgrade/downgrade or manually update rom etc.
