Why Xiaomi is blocking the APK installation by default?

The ban on installations from unknown sources is not a whim of Xiaomi, but a requirement of Google for all Android devices.

1. Protection against malware.According to Kaspersky, more than 30% APK-files distributed outside of Google Play contain advertising modules or spy scripts, even popular apps (such as modified WhatsApp). GB) They may steal account data.

2. Compliance with license agreements: Many APKs (especially pirated versions of paid software) violate Google Play Protect’s rules. Xiaomi risks losing access to Google services if it massively allows circumvention of restrictions.

3. Update Control: Apps from the Play Market are automatically updated, while APKs from third-party sources are often left without security patches, making the device vulnerable to attacks through outdated versions of programs.

⚠️ Note: Redmi Note 8 Pro with firmware MIUI Global, after unlocking unknown sources, the system will remind you of the danger daily through the notification "Device security is at risk." → Security Centre → Notifications.

However, blocking doesn’t mean that APK installation is impossible. The manufacturer provides a legal way to bypass the restrictions – through permission for specific applications (such as a file manager or browser), which is more secure than full unlocking, since you control which programs you trust to install.

Method 1: Standard unlocking through “Security settings”

This is the simplest method that works on most MIUI versions (11 to 14) and is the same as the Redmi Note 8 Pro with global (Global) or European (EEA) firmware:

1. Open Settings (the gear icon on the main screen).
2. Go to the Appendix section → Application management.
3. Click on the three dots in the top right corner and select Special Access.
4. Slip on the item Installation from unknown sources.
5. In the list of applications, select the one you plan to install APK through (for example, File Manager, Chrome or Xiaomi Browser).
6. Activate the “Allow installation from this source” switch.

If the list does not contain the desired application, install it first (for example, download it). APK-installer from Play Market, then go back to the settings and allow it to install.

What to do if the “Allow” button is inactive?

• 🔄 Restart the device – sometimes system restrictions are reset after a reboot.
• 📱 Update. MIUI Up to the latest version: in old firmware there are bugs with access rights.
• 🔒 Check your password/fingerprint: some versions MIUI Requires confirmation of unlocking the screen before changing security settings.

⚠️ Note: Redmi Note 8 Pro with firmware for the Chinese market (CN-ROM) The item "Installation from unknown sources" may not be on the menu, in which case use an alternative method (section 4 of this article).

Method 2: Resolution through Developer Settings (for power users)

If the standard method didn’t work, you can activate APK installation through developer mode, which is suitable for users who have already enabled USB Debugging or changed system settings.

• 📱 You have a corporate device with security settings restrictions.
• 🔄 Standard method does not work due to a bug in the firmware.

💡

If ADB does not recognize the device, install Xiaomi USB Drivers from the official website and check if File Transfer (MTP) mode is enabled when connecting to the PC.

Warning: Installing via ADB bypasses some MIUI security checks. Do not use this method for APKs from unreliable sources - the risk of malware infection increases by 2-3 times.

Method 3: Bypassing the restrictions for Chinese firmware (CN-ROM)

On the Redmi Note 8 Pro with Chinese firmware (CN-ROM), the path to security settings is different, and some options are hidden, due to local laws in China that require manufacturers to tighten control over the installation of third-party software.

To unlock the APK installation on CN-ROM, follow the algorithm:

1. Open the Settings. → Password and security.
2. Go to Authorization and Lock (or Application Privileges in MIUI 14).
