Installing apps from unknown sources on Xiaomi Redmi smartphones is a necessary feature for users who want to install APK-files outside of Google Play or Mi App Store, which may be used to test beta versions of programs, use specialized software or applications that are not available in official stores. MIUI HyperOS setup is hidden deeper than pure Android and requires additional steps for each model separately.
It is important to understand that allowing installations from unknown sources not only opens up access to advanced features, but also increases security risks. In this article, we will discuss how to properly enable this option on different versions of firmware (MIUI 12/13/14 and HyperOS), which Redmi models have features, and how to minimize threats when installing third-party APKs.
Why is Xiaomi blocking the installation from unknown sources?
Xiaomi defaults to disable the ability to install APKs from external sources not because of a whim, but for three key reasons:
- 🛡️ Malware protection: More than 60% of Android viruses are spread through fake malware APK-files masquerading as popular apps (such as modified versions of WhatsApp or Telegram).
- 📱 Compliance with Google Policy: To Certify Devices for Google Mobile Services (GMS) Manufacturers are obliged to restrict installation from unverified sources.
- 🔄 Controlling ecosystems MIUI: Xiaomi is promoting its Mi App Store, where all programs are pre-moderated.
However, the lock is not absolute: the system allows you to selectively allow installation for specific applications (for example, browsers or file managers), which reduces the risks. MIUI/HyperOS from pure Android, where the resolution is given globally.
Preparing the phone before turning on the option
Before you change your security settings, follow a few mandatory steps:
Update the firmware to the latest version|Create a backup copy of the data|Check your phone for viruses (e.g., Google Play Protect)|Download. APK only from verified sources (APKMirror, official developer sites)-->
Pay special attention to the MIUI/HyperOS version: on older firmware (below MIUI 12), the path to security settings may be different. To find out your version, go to Settings → About Phone → MIUI Version. If you have HyperOS, the path will be Settings → About Phone → HyperOS Version.
⚠️ Note: On Redmi Note models 10/11/12 HyperOS may be activated when you turn on a "potential threat" alert, which is the standard behavior of the system, and you can ignore it if you're sure of the source. APK.
Step-by-step instructions for MIUI 12/13/14
The algorithm for enabling the installation from unknown sources on MIUI depends on the firmware version, but the general scheme is maintained.
- Open Settings and go to the Applications → Application Management section.
- In the upper right corner, press three dots (⋮) and select Special Access.
- Slip on the item Installation from unknown sources.
- In the application list, select the one you will install the APK through (e.g., Browser, Files, or Mi File Manager).
- Activate the switch Allow installation from this source.
On MIUI 14, the path may be shortened: Settings → Applications → Application Management → Install unknown applications. Once activated, a warning will appear – confirm the action.
💡
If the application you want is not listed on the Installation from Unknown Sources list, open it at least once and the system will add it to the list automatically.
Features for HyperOS (Redmi Note 12/13, Redmi K60 and later)
HyperOS is Xiaomi’s new shell, replacing MIUI in 2023-2026, and the logic of APK’s installation permission has changed:
- 🔧 The setup became linked to a specific file, not an application, so permission is requested the first time you try to install it. APK.
- 🔒 After installing one APK For the next file, you will need to confirm the permission again.
- 📂 The path in settings: Settings → Annexes → Application management → Installation of packages.
For example, on the Redmi Note 13 Pro+ with HyperOS 1.0, the algorithm is as follows:
- Download. APK-file and try to open it.
- The system will give a warning window – click Settings at the bottom of the screen.
- Turn on the switch for the current source (such as Files or Telegram).
- Return to the installation and confirm the action.
⚠️ Note: Some system applications (such as Mi Video or Mi Music) cannot be eligible for installation on HyperOS. APK. Use Files or Browser for this purpose.
Table: Compatibility of Redmi models and firmware versions
| Model Redmi | Supported firmware | The path to settings | Features |
|---|---|---|---|
| Redmi Note 9/10 | MIUI 12–13 | Settings → Applications → Special access → Installation from unknown sources | Permission is required for each application separately. |
| Redmi Note 11 | MIUI 13–14 | Settings → Applications → Application Management → Installation of Unknown Applications | MIUI 14 may need to be rebooted after changing settings. |
| Redmi Note 12 | MIUI 14 / HyperOS | Settings → Applications → Application Management → Package Installation | HyperOS is requested for permission when the APK is first installed. |
| Redmi K50/K60 | HyperOS | Settings → Applications → Application Management → Package Installation | Supports installation via adb install without additional permissions. |
| Redmi A2/A3 | Android Go (without MIUI) | Settings → Applications → Special access → Installation of unknown applications | There is no binding to specific applications – the resolution is global. |
How to minimize risks when installing an APK
Allowing installations from unknown sources opens the door not only to useful software, but also to viruses.
- 🔍 Check the hash amounts of files: Compare MD5 or SHA-1 downloaded APK You can use the official data on the developer's website, and you can use applications like Hash Droid.
- 🛡️ Install antivirus: Malwarebytes or Bitdefender is more effective than Google Play Protect for detecting modified software APK.
- 📥 Download only from verified sources: List of reliable sites for APK APKMirror checks files for changes. APKPure has a verification system. Official developers' sites (for example, Telegram for beta versions).
- 🔄 Reverse permissions: After installing the desired APK Turn off permission for source in settings.
If the application requests suspicious permissions (such as SMS access or administrator rights) after installation, delete it immediately and check the phone for viruses. On MIUI/HyperOS, this can be done through Settings → Security → Scanning.
💡
Even if the APK is downloaded from a reliable source, never install it via adb install with superuser rights (root) that bypasses all MIUI protection systems.
