I used poco launcher on my redmi note 5pro and redmi note 4x. it vwas great. the only drawback was the system backup can't backup the poco launcher data on my redmi note 5 pro, after the hard reset one month ago and I have to re arrange the launcher page. I don't know now whether it data can be backup by miui backup, else please inprememt a backup function within the poco launcher like Nova launcher done.
