This measure protects the device from malware, but often prevents users from installing it. APK-files from alternative stores (such as APKMirror), beta programs or enterprise applications. In this article, we will discuss how to correctly allow installation from unknown sources on different versions. MIUI (12 to 14), what risks this entails and how to avoid common errors such as “Installation locked».

It's important to understand that the procedure differs depending on the firmware version and the phone model. For example, on the Redmi Note 12 with MIUI 14, the path to security settings may differ from the Poco X3 on MIUI 13.

Why is Xiaomi blocking APK installations from unknown sources?

The ban on installing third-party APKs is not a whim of Xiaomi, but a requirement of Google Play Protect and Android security policies.

• 🛡️ Malware protection: According to Kaspersky, in 2023 12% APK From third-party sources contained Trojans or spyware modules. MIUI Automatically scans files for viruses before installation.
• 📦 Conflict with system applications: Some APK can overwrite system services (e.g. com.android.vending), which leads to failures.
• 🔒 Violation of license agreements: Installing pirated versions of paid apps (such as Spotify Premium or Netflix with mods) can result in a Google account being blocked.
• 🔄 Incompatibility with the Android version: APK, Android 12 may not work on Android 14 due to changes in the API.

However, the lock is not absolute. Xiaomi allows you to manually allow installation for specific sources (such as the Chrome browser or file manager).It is a flexible approach: you do not open access to all APKs in a row, but only to those you trust.

⚠️ Note: If you are installing APK To circumvent regional restrictions (e.g. Google Play Services in China), please note that Xiaomi may cancel the warranty if modified system files are detected.

Method 1: Standard resolution via Security Settings (MIUI 12–14)

This is a universal method for most Xiaomi, Redmi and POCO devices on current firmware versions. Instructions are suitable for models from 2020 to 2026 (Redmi Note 11, Xiaomi 13, POCO F5, etc.).

Steps:

1. Download. APK-file in the memory of the phone (for example, through a browser or Telegram).
2. Open the file manager (standard MIUI or Files by Google).
3. Find the downloaded file and tap it, and the system will give you a warning: "Installation locked. Permit installation from this source?"
4. Click Settings in the warning window and it will redirect you to Settings → Applications → Special Permissions → Install Unknown Apps.
5. In the list, find the application that downloaded the APK (such as Chrome or Files) and turn on the “Allow installation from this source” switch.
6. Return to the APK file and try again.

If the app is not on the list, try downloading the file from another source (e.g. Firefox instead of Chrome).Some devices (e.g. Xiaomi 12T) may need to allow access in the Settings → Privacy → Special Permissions section.

Download the file only from verified sources (APKMirror, APKPure)

Check the hash file (MD5/SHA-1) on the developer’s website

Disable VPN (some APKs block installation when an active VPN is in place)

Charge your phone at least 30% (for long installation processes)

Method 2: Resolution through Application Permissions (MIUI 13–14)

Since MIUI 13, Xiaomi has moved some of its security settings to App Permissions, a method that comes in handy if the standard path has failed or the option is hidden.

Algorithm:

1. Open Settings → Applications → Application Management.
2. In the upper right corner, tap three points (⋮) and select "Special Access».
3. Scroll down and find the item “Install Unknown Apps”.
4. In the list, select the application that will install the APK (such as File Manager or Browser).
5. Activate the "Allow from this source" switch.

On some devices (such as the POCO X5 Pro), this section may be called “Installation Permits.” If you don’t see the right item, try searching by settings (the magnifier icon at the top of the screen) and querying “unknown sources.”

⚠️ Attention: On devices with MIUI For a global market (e.g., Xiaomi 13 Lite for Europe), there may be no resolution option for some system applications (e.g., Downloads.

Method 3: Bypassing a lock through ADB (for power users)

If standard methods do not work (for example, the option of gray or not), you can allow installation through the ADB-This method is suitable for devices with unlocked OEM Unlock and enabled debugging by USB.

Instructions:

1. Activate Developer Mode: Go to Settings → About Phone and tap on the MIUI Version 7 times.
2. Return to Settings → Additional → For developers and enable “Debugging by USB”.
3. Connect your phone to your PC, install ADB drivers (for example, via Mi PC Suite) and open the command prompt.
4. Enter the command to check the connection: Adb devices should appear the name of your device.
5. Apply permission for installation from unknown sources: adb shell settings put global install_non_market_apps 1
6. Reboot the phone.

You can then install APKs without further confirmation. To reverse the changes, do:

adb shell settings put global install_non_market_apps 0

On devices with MIUI 14 and Android 13+, the ADB command may not work due to new restrictions by Google, in which case you will need to temporarily disable Google Play Protect in the security settings.
