MIUI Unknown Sources

MIUI hides sideload behind 'Install unknown apps' or an Install via USB developer toggle, depending on the year. You allow the app that is installing (Chrome, Files, GetApps), not a global forever-yes from a pop-up ad.

PathPer-app install unknown.
InstallerChrome or Files.
GetAppsMay hijack. Stay on the file.

Typical path

Settings → Privacy / Apps → Special permissions → Install unknown apps → Chrome or Files → Allow. Then tap the APK in Downloads.

GetApps or Security scan

If Xiaomi Security deletes the file, restore / allow this app. Do not download a 'MIUI rummy booster'.

Then OTP

Same as any Android. Unknown sources is the generic page.

Where this sits on RummyCulture
