Installing third-party apps on Xiaomi TV with Android TV operating system via a flash drive is a challenge faced by users who want to expand the functionality of the device outside the official Google Play Store. Unlike smartphones, Android TVs have a number of limitations: blocked by default installation of APK from unknown sources, the lack of a full file manager and a specific interface optimized for the remote control.
It's important to understand that the process is different from installing on Xiaomi smartphones - there is no developer mode in the usual form, and the security settings are hidden deeper. APK, File Manager choice, but also nuances: how to get around the error "Application not installed" due to incompatibility of the processor architecture (ARM/x86), What formats of flash drives are supported (FAT32, exFAT, NTFS), and why some APK-Files are not displayed in the Explorer. Instructions are relevant for Mi models. TV 4S/4A/4X/5X, Redmi Smart TV and others based on Android TV 9.0–12.0.
Preparation: What will be needed for installation
Before you start the installation, make sure you have everything you need, and the absence of at least one component can cause failures or inability to complete the process.
- 📁 USB-drive (flash drive) up to 32 GB, formatted in FAT32 (recommended for maximum compatibility). NTFS ExFAT can work, but sometimes it causes reading errors.
- 📱 APK-App file downloaded from a trusted source (e.g. APKMirror) Make sure the version is Android compatible TV — Many smartphone apps aren’t optimized for remote control.
- 🔌 USB-Power hub (optional) If the TV ports don't provide enough current, the flash drive may not be recognized.
- 🖱️ Wireless mouse (recommended) Navigating the file system through the remote control is extremely inconvenient - the mouse will speed up the process.
Pay special attention to choosing APKs. For example, YouTube or Netflix are already pre-installed on Xiaomi TV, and third-party versions may conflict with system versions. Installation of Kodi, SmartTubeNext (an alternative YouTube client) or emulators (RetroArch) requires additional settings, which we will discuss below.
Step 1: Allow installation from unknown sources
By default, Android TV blocks APK installation from external sources, so you need to change your security settings to unlock this feature, and importantly, the path to these settings may vary depending on the firmware version and the TV model.
- Open the settings (cog icon in the top menu).
- Go to Device → Security and Restrictions (or Personal Data → Security on older versions).

You can install a file manager in two ways:
