i have problems with miui bugs. sometimes it doesn't let me update. Sometimes it rakes 5 minutes to refresh the gallery and see something in the gallery. And also my Poco x3 has battery issue. It's battery is disgusting. I hate it's written 5260 mah but it is worst than vivo s1 4500 mah battery. And also the charging speed is now bad. In the beginning it was cool. But now i hate it.
