Install applications from unknown sources on Xiaomi smartphones (including Redmi models and other devices) POCO) — necessary function for users who want to install APK-The manufacturer, however, blocks this feature by default for security reasons, and in this article we will discuss how to enable the resolution correctly, what risks it entails, and why standard instructions may not work on new versions. MIUI.
It's important to understand that permission to install from unknown sources is not a global setup, but a customized resolution for each application you're trying to install APK through. For example, if you downloaded a file through Chrome, it's the browser you want to give permission to, not the system as a whole. This makes it harder for beginners, but it increases security. Next, step-by-step instructions for different versions of MIUI, including MIUI 14 and HyperOS, and tips for minimizing risks.
Why is Xiaomi blocking the installation from unknown sources?
The main reason is malware protection, unlike Google Play, where applications undergo moderation, APK-Internet files may contain:
- 🦠 Viruses and Trojans (such as FluBot or Joker) that steal SMS bank card details)
- 🕵️♂️ Spyware (collection of location, contacts, photos)
- 💸 Advertising modules (implement banners in other apps or replace ads in games)
- 🔓 Backdoors (remote access to a device without the user’s knowledge)
According to Kaspersky, in 2023, 38% of malicious applications for Android were distributed through the Internet. APK-Xiaomi, like other manufacturers, restricts this function by default, but the lock is not absolute: the user can manually allow installation for specific sources (browsers, file managers, etc.).
⚠️ Note: Even if you have downloaded APK from a verified site (such as APKMirror), check the hash file before installing it (MD5/SHA-1) Attackers often replace popular apps (such as modified versions of WhatsApp or Telegram).
Step-by-step: how to enable permission on Xiaomi (MIUI 12-14 and HyperOS)
The algorithm depends on the firmware version. Below is a general-purpose instruction that works on most Xiaomi, Redmi and POCO devices (including the 2020-2026 models). If your device runs on HyperOS, skip step 3 - there is no separate "Security" item in the new shell.
Download. APK-file in device memory (internal or microSD card)
Remember through which application the file is downloaded (browser, Telegram, file manager)
Check the file for viruses (for example, through Dr.Web Light)
The battery must be at least 30% charge (in case of long-term installation)-->
- Open Settings → Applications → Application Management.
- Find the app that APK is downloaded from (e.g. Chrome, Files, Telegram) and tap it.
- In MIUI 12-14, select Permissions → Install from unknown sources → Switch the slider to Allow. In HyperOS: Go straight to Permissions → Special Access → Install Unknown Applications.
- Confirm the action in the pop-up window (a password or fingerprint may be required).
- Go back to the scallop. APK-You can put the file and tap it.
If the installation is blocked after these actions, check:
- 🔄 Is the mode for children included in the security settings.
- 🛡️ Does the installation block antivirus (for example, Mi Security or third-party Avast).
- 📁 Not damaged? APK-File (try to download it again).
💡
If you install APKs frequently, create an APK folder at the root of your internal memory and add it to the antivirus exceptions, which will speed up the scanning of files before installing.
Features for different Xiaomi models
Some Xiaomi devices have unique nuances when it comes to installing from unknown sources, and the table below highlights the key differences for popular models:
| Model/Series | Features of settings | Frequent problems |
|---|---|---|
| Redmi Note 10/11/12 | Permission is given through Settings → Applications → Application Management → [Application] → Special Access. | After upgrading to MIUI 14, the "Install Unknown Applications" item may disappear - you need to reset security settings. |
| POCO F3/F4/F5 | In HyperOS, the path: Settings → Applications → Permissions → Special Access. | When installing modified firmware (e.g., Pixel Experience), you may need to disable MIUI Optimization in the developer settings. |
| Xiaomi 13/14 | Supports dynamic permissions – you can give access to one installation. | The system can block APKs with a modified certificate (e.g. patched games). |
| Redmi 9/9A/9C | On older versions of MIUI (up to 12.5), the resolution is given globally for all applications. | Often, the "Application not installed" error occurs due to a lack of memory in the /data partition. |
For HyperOS devices (such as Xiaomi 14 or Redmi K70), Sandbox is also available, which allows untested APKs to run in an isolated environment without risk to the main system, to enable:
- Go to Settings → Apps → Sandbox.
- Select Add App and specify the path to APK.
- Run the installation in secure mode.

Risks and how to minimize them
Allowing installations from unknown sources opens up potential vulnerabilities, and here are the real cases Xiaomi users have encountered:
- 💳 Bank card theft: In 2022, through a fake SberBank Online app (spread as a scam) APK) The attackers stole more than 50 million rubles from users in Russia.
- 📱 Device lock: Simplocker viruses encrypt files on phone and demand ransom in bitcoins.
- 🔋 Hidden Mining: Some APK (For example, modified versions of Minecraft secretly use the resources of the phone to mine cryptocurrency, which leads to overheating and bloating of the battery.
To reduce the risks, follow the rules:
⚠️ Warning: Never install APK, If: The file weighs suspiciously little (e.g. WhatsApp can't be 2MB - real size) ~50MB) The site requires you to disable the antivirus before downloading the file resolution is.apk.exe or.apk.jar (double extension is a sign of a virus).
Before installation, check:
- Hash file (MD5/SHA-1) via VirusTotal or MetaDefender.
- Reviews of the site on forums (e.g., 4PDA or XDA Developers)
- Digital signature (the APK must have a Signature field).

Frequent mistakes and their solutions
Even after enabling permission, Xiaomi users encounter errors when installing APK. Consider the most common:
| Mistake. | Reason. | Decision |
|---|---|---|
| Failed to install the app. | APK is designed for a different processor architecture (e.g. arm64 instead of armeabi-v7a). | Download the APK version for your architecture (check in Settings → About Phone → Kernel version). |
| Application not installed | Conflict with the already installed version or lack of space in /data. | Remove the old version of the app and clear the cache through Settings → Storage. |
| Installation blocked by security policy | Enterprise profile is active (for example, through Microsoft Intune). | Delete your work profile in Settings → Accounts → Work profile. |
| Packet analysis error | A damaged APK or incompatible version of Android. | Check the integrity of the file and the compliance of the Android version (in manifest APK). |
If the error persists, try:
- 🔧 Install APK through ADB (see spoiler above).
- 📲 Use an alternative installer (e.g, SAI — Split APK Installer for multi-file applications).
- 🔄 Reboot your phone in Safe Mode (hold the power button) → Restart in Safe Mode) and repeat installation.
💡
If the APK isn’t installed on Xiaomi with HyperOS, try temporarily disabling MIUI Optimization in the developer settings.
Alternative ways to install APKs without including unknown sources
If you don’t want to risk security, but you need to install an app outside of Google Play, there are legal workarounds:
- Through Google Play (if the app is removed): Some APKs can be installed if you know the direct link. For example, Fortnite or Huawei AppGallery have official pages that open through the browser and redirect to the Play Market for installation.
- Use of Aurora Store: This is an open client for Google Play that allows you to download APK without a Google account. Installed via F-Droid (without having to include unknown sources for it).
For enterprise users, Xiaomi also has the Mi Enterprise App Store, a private app store where an administrator can download internal APKs for employees without having to include unknown sources on each device.
How to disable permission after installation
Once you have installed the desired APK, it is recommended to disable the permission for the application through which you downloaded the file, which will reduce the risk of accidental installation of malware in the future.
- Go to Settings → Applications → Application Management.
- Select an app (such as Chrome or Files).
- Open Permissions → Special Access → Install Unknown Applications
- Switch the slider to the position Prohibit.
For additional security:
- 🧹 Remove the downloaded APK-file.
- 🔍 Conduct a full antivirus scan (e.g. Malwarebytes).
- 🔄 Update Google Play Protection in Settings → Google → Security.
⚠️ Note: If you frequently install APK From unknown sources, consider creating a separate user profile on your phone (Settings) → System system → Multiple users: This isolates potential threats from the main account.
