I'll try this on Miui 12 when i got any device having Miui 12 or my Redmi note 5 pro got Miui 12 update. And then i will post update here. Try it and write in reviews that this app remover is helpful for you or not.

So currently we haven't launched any system app remover pro apk for our app. So if you got apk outside from Google playstore which says its pro apk for redmi system manager, then dont trust them.

That's why we are using google ads inside out app so we can get some profit from it without asking from you.
