The Xiaomi Mi TV 4 runs on a custom Patchwall UI on top of Android and doesn't use any of the services offered by Google. There's no Play Store and you'll have to make do with the apps and services that come pre-loaded on the smart TV. But as this is Android, you can always side-load apps via an APK file. We show you how.
Note: Downloading apps from unauthorised sources may result in bugs or even malware. We suggest using the utmost precaution and trying this only if you're sure about what you're doing.
