Installing applications from unknown sources on Xiaomi smartphones (including the Redmi and POCO lines) is a procedure that every user faces who wants to bypass the restrictions of Google Play. Whether you want to install a beta version of the program, an application from a third-party store (for example, APKMirror or Aptoide), or specialized software that is not presented in the official directory – you can not do without unlocking this feature.
However, MIUI (branded shell Xiaomi) has its own peculiarities: not only do you need to allow installation from unknown sources in the security settings, but sometimes you have to deal with additional system limitations. In this article, we will discuss all the current ways to unlock on MIUI 14/15 (Android 13/14), including solutions for cases when the “Allow Installation” button is inactive or disappears after a reboot.
Importantly, the procedure is different from the standard for pure Android, so the instructions for Samsung or Pixel will not work here, and we will also discuss security issues – what risks are associated with installing APK from unverified sources and how to minimize them.
Why is Xiaomi blocking the installation from unknown sources?
Restriction on installation APK-Files outside of Google Play are not a whim of the manufacturer, but a security measure built on the Android level. However, Xiaomi adds its layers of protection, which causes confusion among users:
- 🛡️ Malware protection: According to Kaspersky, more than 30% of mobile viruses are spread through fake malware APK-files masquerading as popular apps (such as modified versions of WhatsApp or TikTok).
- 📦 Quality Control: Google Play checks apps for compliance with privacy policies and compatibility with Android versions.
- 🔒 Politics MIUI: Xiaomi further restricts installation to prevent conflicts with system services (e.g. miui.optimization).
- 📱 Regional restrictions: Some models for the Chinese market (e.g. Xiaomi 13 Pro) CN) Blockages are stricter due to local censorship laws.
Interesting fact: on devices with global firmware (Global ROM), unlocking is usually easier than on Chinese (China ROM), where you may need to unlock the bootloader.
⚠️ Attention: Installation APK Unknown sources disable automatic application verification via Google Play Protect, which means that malware may go undetected until activated.
Preparation for installation: what to do before unlocking
Before you move on to security settings, follow these steps to avoid errors:
Download. APK-file only from verified sources (for example, APKMirror, the official website of the developer)
Check the integrity of the file (the size must match the size indicated on the site)
Make sure that the device has enough memory (minimum 200 MB of free space)
Disable VPN or proxy – they can block access to security settings
Battery charge must be at least 30% (when installing large APKs)
-->
Pay special attention to the source APK. For example, files from torrent trackers or little-known forums often contain:
- 🦠 Embedded cryptocurrency miners (consume battery resources).
- 🕵️ Spyware that collects your account data.
- 📱 "Trojan versions of apps (e.g. FakeBank, stealing bank card data).
To check the file, use online services like VirusTotal or the Malwarebytes app (available on Google Play). If the APK weighs significantly more than the original application (for example, Telegram weighs 30 MB, and the downloaded APK is 80 MB), this is a reason to be wary.

Step-by-step: how to allow installation from unknown sources on MIUI
The process depends on the version of MIUI and the model of the smartphone. Below is the universal algorithm for MIUI 14/15 (Android 13/14), which works on most devices (Redmi Note 12, POCO X5, Xiaomi 13T, etc.).
Method 1: Through security settings (main method)
- Open Settings → Applications → Application Management.
- Slip on the three dots in the upper right corner and select Special Access.
- Select Install Unknown Applications.
- In the list, find the application through which you will install APK (For example, file manager, Chrome or Xiaomi File Manager and enable the Allow installation switch from this source.
Important: If the desired application is not in the list, first open the APK through it - the system will automatically add it to the special access menu.
Method 2: For older versions of MIUI (up to 12.5)
On MIUI 11/12 firmware, the path is different:
- Go to Settings → Privacy → Special permissions.
- Select Install Unknown Applications.
- Activate the resolution for the desired source (e.g., Browser).
What if the "Allow installation" button is inactive?
Method 3: Through ADB (for power users)
If standard methods don’t work (for example, on China ROM), use the ADB command:
adb shell settings put global install_non_market_apps 1Once done, restart the device. This method bypasses the limitations of MIUI, but requires the developer mode to be turned on and a PC connection.
⚠️ Note: On some models (Xiaomi) 12S Ultra, Redmi K50 Gaming after use ADB Mi Protect can work, blocking the installation for 24 hours, in which case only waiting or resetting through Fastboot will help.
Table: Compatibility of methods with MIUI versions
| Unlocking method | MIUI 15 (Android 14) | MIUI 14 (Android 13) | MIUI 12.5 (Android 11/12) | China ROM |
|---|---|---|---|---|
| Security settings (main) | ✅ Yes. | ✅ Yes. | ✅ Yes. | ❌ No, I need you. ADB) |
| Special access through "Application Management" | ✅ Yes. | ✅ Yes. | ❌ No (old way) | ❌ No. |
| ADB-team | ✅ Yes. | ✅ Yes. | ✅ Yes. | ✅ Yes (may require unlocking the bootloader) |
| Developer mode + USB-debugging | ✅ Yes (additional) | ✅ Yes. | ✅ Yes. | ✅ Yes (required) |
Note: On devices with China ROM (e.g. Xiaomi Mix Fold 3), you may need to unlock the bootloader via the Mi Unlock Tool, which voids the warranty.
Frequent mistakes and their solutions
Even after unlocking, APK installation can end in errors, and let’s look at the typical problems and ways to fix them:
Error: "I failed to install the application"
Causes and solutions:
- 📌 Damaged. APK: Download the file again. Check the hash amount (MD5) developer's website.

Error: "Application not installed"
Often occurs due to:
- 🔧 Lack of permissions: Check that in Settings → Annexes → Permits for the installation of APK All necessary options (camera, microphone, etc.) are included.).
- 🔧 Restrictions MIUI: Some system applications (e.g. Mi Video) block the installation of competitors. ADB: adb shell pm disable-user --user 0 com.miui.video
Error: "Parsing error"
This means that the system cannot recognize the APK format.
- 🔄 Rename the file by removing the Cyrillic and spaces (e.g, app_v2.1.apk).
- 📱 Try installing it through another file manager (e.g. Solid Explorer).
- 🛠️ If APK — This is a split-APK (multiple files) SAI (Split APK Installer from Google Play.
💡
If installation is interrupted by 50-70%, try turning off the "App Check" option in Settings → Security → Virus Protection. This will speed up the process, but increase the risks.
