Xiaomi Redmi Note 10 smartphones block the installation of applications (.apk files) from sources other than Google Play Market by default. This is a security measure designed to protect the device from malware. However, sometimes users need to install an application that is not in the official store - for example, a beta version of the program, specialized software for work or games from alternative sources.
Enabling this option opens access to manual installation APK-Files, but it is important to understand: on Xiaomi Redmi Note 10 MIUI 12.5+ It asks for permission separately for each browser or file manager you're trying to install an app through, which is different from the older versions of Android, where a single global switch was enough. Next, we will understand how to properly configure the device, what risks exist and how to minimize them.

Allowing installations from unknown sources opens up potential vulnerabilities. Follow these rules to protect the Xiaomi Redmi Note 10:
⚠️ Warning: Never install APK-Intruders often distribute Trojans under the guise of hacked versions of popular games (such as Free Fire or Free Fire). PUBG Mobile) or WhatsApp mods.

Alternative ways to install applications
If the inclusion of unknown sources is not available for some reason (for example, due to corporate restrictions), consider these methods:
- 🌐 Web versions of applications. Many services (like Telegram or Spotify) have full-featured web versions that run through a browser without installing.
- 📦 Sideload through ADB. Connect your phone to your PC and use the command: adb install path to file.apk To do this, you need to enable debugging by USB In Settings → The phone. → Version. MIUI (7 times press the item, then return to the Additional → For developers).
- 🔗 Alternative stores: Install Aurora Store (an anonymous client for Google Play) or APKPure - they offer proven stores. APK automatic-update.
For users who frequently install APKs, we recommend creating a separate user on the phone through Settings → System → Multiplayer mode. This will isolate potentially dangerous applications from the main profile.
Features for different versions of MIUI
The interface and settings may vary depending on the firmware version, and the key differences for the Xiaomi Redmi Note 10 are as follows:
| MIUI version | The path to settings | Features |
|---|---|---|
| MIUI 12.0–12.5 | Settings → Annexes → Application management → ⚙️ → Special access → Installation of unknown applications | Password confirmation required at first inclusion |
| MIUI 13.0+ | Settings → Applications → Special permissions → Installation of unknown applications | Added verification of APK signature for compliance with the security profile Xiaomi |
| MIUI 14 (Android 13) | Settings → Privacy → Special permissions | Notice of potential risks is introduced for each permit inclusion |
On MIUI firmware for the global market (e.g. MIUI Global), the path to settings may be different from the Chinese version (MIUI China). If you use custom firmware (like Pixel Experience or LineageOS), the settings will be consistent with standard Android without the MIUI shell.
💡
On MIUI 14+, the system automatically resets permission to install unknown applications after 7 days without using, which means that the option will have to be re-enabled for a new installation.
