Xiaomi smartphones are famous for their versatility and affordable value, but the built-in MIUI protection system is often perceived by users as overly intrusive. Device owners often face blocking the installation of applications from unknown sources or the aggressive behavior of the built-in antivirus that removes harmless modified programs. There is a natural desire to learn how to turn off security on Xiaomi to gain full control of their gadget.
Disabling security mechanisms is a dual process that requires users to understand the risks, on the one hand, it opens up access to a wide range of software and customization of the system, on the other, makes the device vulnerable to real threats. In this article, we will discuss in detail all layers of protection of the MIUI shell and Android, explaining which ones can be safely deactivated for comfortable use.
Analysis of the built-in security system MIUI
The central element of protection in Xiaomi smartphones is the “Security” application, which combines the functions of an antivirus, a memory cleaner and a call blocker. This system works at the deep level of the operating system, which allows it to effectively prevent the launch of malicious code, but can also interfere with the installation of specialized software. Users often confuse system restrictions with viruses, when in fact these are standard Mobile Security mechanisms.
It is important to understand that it is impossible to completely remove this component without root rights, since it is integrated into the system partition, but its functionality can be significantly limited by disabling real-time scanning and checking of installed packets, this is the first step to unlock the capabilities of the device for advanced use.
It is worth noting that different versions of firmware (Global, China, EEA) the location of settings may vary slightly, but the logic of the work remains the same for all models of Redmi and Poco. Before making changes, it is recommended to back up important data to avoid loss of information in the event of a system failure.
⚠️ Warning: Disabling system antivirus reduces the level of protection of personal data. Do this only if you are confident in the sources of the installed applications.
Disable antivirus and scanning in real time
To get started with security settings, you need to go to the appropriate system application, find the Security icon (green shield) on your desktop or menu and run it. Inside the interface, you will be greeted by the Security Check button, but we need access to the settings, which is usually hidden in the upper right corner in the form of a gear.
In the MIUI settings menu, you should find the "Antivirus" or "Scanning Settings" option, and here is the "Real-time protection" switch, which will stop background checks of files and running processes, which will significantly reduce the load on the processor and battery, and will allow you to run modified applications.
Additionally, the menu recommends disabling the "Get virus updates" feature, which will prevent new signature databases from automatically downloading, which may begin to recognize your tools as a threat in the future, and after these actions are performed, the built-in guard will stop interfering with the device.
⚠️ Warning: After disabling the real-time scanning, the system will stop alerting you to potentially dangerous activities of the installed programs.
Configure permissions to install unknown applications
One of the most common problems when trying to APK-The file from the browser or file manager is locked by the Android system. Unlike Google Play, third-party sources require explicit user permission. MIUI This process has been further detailed to improve security.
To allow installation, go to the basic settings of your smartphone and find the Privacy Protection section. In some versions of the firmware, it may be called Privacy or be located inside the Apps menu. We are interested in the Special App Access section, where you need to select the option “Install Unknown Apps”.
In the list that opens, you will see all the applications that can initiate the installation (browsers, file managers, instant messengers). Choose the source you want, such as Chrome or Explorer, and activate the "Allow Application Installation" switch.
- 🛡️ Browsers: Allow installation for Chrome, Firefox or Opera if downloaded APK through.
- 📁 File Managers: Grant permission to a Files app or a third-party explorer like Solid Explorer.
- 💬 Telegram and WhatsApp also require separate permission to transfer installation files.

Advertising Blocker and Fraud Protection
Xiaomi’s built-in ad blocker works at the DNS level and can conflict with some apps that use their own security certificates, and Fraud Protection can block certain links from clicking as phishing, even if you trust the resource.
To disable these features, go back to the Security app and find the Blocker section. In the settings of this module, you can disable the update of the ad databases. URL-It's useful if you use your own addresses. DNS-filters or want to control network traffic.
It’s also worth checking your Mi Browser settings if you use it as your primary browser. Its privacy settings often include aggressive protection that prevents content from being displayed on sites, and disabling these options will return web pages to normal.
Google Play Protect and Android System Limits
Even after setting up MIUI, users may face restrictions from Google services, such as Play Protect, which scans the device for malware and can block the launch of uncertified applications, an independent layer of protection that works in parallel with Xiaomi’s systems.
To access the Play Protect settings, open the Google Play Store app. Click on the profile icon in the top right corner and select Play Protect. In the menu that opens, you can turn off app scanning through the settings gear, but Google will periodically strongly recommend that you turn it back on.
Another barrier is Find My Device, which if you’re planning to flash or make deep changes to your system, it’s best to temporarily disable this feature in Google’s settings to avoid blocking your account when you change system files.
| Protection component | Location on the menu | Risk of shutdown | Impact on the system |
|---|---|---|---|
| MIUI Antivirus | Security Annex | High-pitched | Possible virus installation |
| Unknown sources | Settings → Confidentiality | Medium. | Installation of any APK |
| Google Play Protect | Google Play → Profile | Medium. | Blocking Certified Applications |
| Ad-blocker | Security Annex | Low. | Advertising in the system |
Developer Mode and Debugging by USB
To fully manage security and disable deep system constraints, access to developer mode is often required, a hidden menu that allows you to interact with the system via a computer using ADB commands. Activation of this mode is standard procedure for enthusiasts.
To activate the mode, go to Settings → About Phone and start quickly clicking on MIUI Version (or OS Version) about 7-10 times. After the message “You became a developer” you can move to advanced settings.
In the menu “Additional» → «For developers, we are interested in the items “Debugging by USB» and “Installation through USB». Inclusion of “Installations through USB» require input SIM-maps and confirmations through SMS, This is a Xiaomi security measure that cannot be circumvented without server authorization.
adb shell pm grant com.android.packageinstaller android.permission.INSTALL_PACKAGESThis command via ADB can help in some cases with additional installation rights if standard methods fail, but using the command line requires caution and understanding the syntax.
Unlocking the bootloader (Bootloader)
The most radical way to disable security is to unlock the bootloader, which removes the digital signature from the system partition, allowing custom recovery, root rights, and firmware changes. Without the unlocked bootloader, access to deep system settings is closed.
The unlocking process requires filing through the Mi Unlock Tool app on a PC and waiting 7 to 30 days. Xiaomi has implemented this mechanism to make it harder for devices to be stolen and unauthorized access to data. Once unlocked, the phone will alert you to compromised boot state at each turn on.
In addition, some high-security banking applications and services (Google Pay, bank keys) may stop working or require additional manipulation of Magisk modules to hide superuser rights.
⚠️ Warning: Unlocking the bootloader will void the software warranty in most service centers.
