hello
instalation on the Mi Mix 3 so far no big bugs, i made a clean install, the app of the camera is the old one no problem there, minor bugs like the battery indicator sometimes dissapear, a little lag, but nothing problematic, the portuguese translation it's 100% so far, good KcNirvana and your team excelent work.
one advice for the people made a backup e replace that backup, do not install via backup playstore apps, because they will work bad, not install them or reinstall, and they work flawless.exemple facebook, Messenger etc.
Thank you xiaomi.eu team for your hard work
