How to turn off app check on Xiaomi: the full guide

Xiaomi smartphone owners often face intrusive notifications from a built-in security scanner that blocks third-party apps from being installed. This protection system, based on the Avast or Tencent engine, is designed to protect the device from viruses, but in reality often interferes with normal operation. APK-The system can claim that the application is not verified, even if it is absolutely secure and has a digital signature.

Disabling this feature greatly speeds up the installation process and eliminates unnecessary clicks on the screen. However, it is worth understanding that you do this at your own risk, taking responsibility for data security. In this article, we will discuss in detail all available ways to deactivate MIUI Security and system restrictions relevant to current versions of the MIUI 14 shell and the new HyperOS. We will consider both standard methods through settings and more advanced options for experienced users.

Why does a security system block the installation of applications?

The protection mechanism in Xiaomi smartphones works at a deep system level. When you try to run the installation file.apk, first activates the component MIUI Optimizer, which scans the code for malicious scripts. If the file does not have a certificate of a trusted developer or is on a “blacklist”, the installation is blocked. This creates a barrier to accidental infection, but also prevents the installation of modified versions of popular programs.

The main problem is that verification algorithms often work too aggressively, and they can flag legitimate memory cleaners, clients for torrent trackers, or applications modified by enthusiasts as suspicious, requiring an Internet connection to reconcile hash sums with a cloud database, which is not always convenient when using mobile traffic or in areas of poor coverage.

Also, the constant pop-ups are distracting and slowing down, and the user has to wait for the scan to finish, which can last for a few seconds, and then manually confirm their actions. For those who often test software or use alternative app stores like F-Droid or Aurora Store, this becomes a serious obstacle in working with a smartphone.

⚠️ Warning: By disabling system protection, you remove the barrier that prevents the installation of potentially dangerous software. Make sure you only download files from trusted sources so that your personal data is not at risk of theft.

Basic security settings in MIUI and HyperOS

The first step to solving the problem is to standardize the security application itself, and that's where the basic switches that control how the scanner loads files, and the interface may vary slightly depending on the firmware version, but the logic remains the same across the brand's devices.

You have to open a standard app called Security, and in the upper right corner of the screen is the gear icon that opens the settings menu, and here we're interested in Scanning Settings, and that's where the options are hidden, which force you to check before you install any external application.

You should find the option "Check installation files" or "Scan before installation" and put the slider in an inactive state. It is also recommended to disable the option "Recommend reliable applications", as it often redirects the user to the GetApps store, offering to replace the desired file with an analog.

• 📱 Open the Security app on the home screen.
• ⚙️ Click on the settings icon in the upper right corner of the interface.
• 🔍 Select the menu Settings Scanning.
• ❌ Disable the switchboard "Check the installation files".

Once these steps are done, the system will stop automatically starting the scanner every time the installer starts, but in some cases, especially on newer versions of HyperOS, settings may be reset or supplemented with new layers of protection that require additional manipulation.

Disabling verification through browser settings

Often, the lock occurs immediately when a file is uploaded or immediately after it is saved. Browsers built into the MIUI shell also have their own protection modules. They can block the transition to the site or download a file, marking it as dangerous, even before you try to install it.

If you use a standard Mi Browser browser, you need to go to its settings, which are usually available through a menu of three dots or stripes. In the section "Privacy and Security" or "Real-time Protection", you should find the option "Secure browsing" and deaktivirovat' it, which will allow you to download files without prior verification by cloud services.

For Google Chrome users, the situation is similar. There is a "Security" section in your browser settings where "Safe browsing" is activated. Disabling this feature will remove the red warning screens that may appear when you visit sites with direct links to the site. APK-file.

💡

Use specialized download managers such as ADM or 1DM, which have built-in bypasses of some limitations and allow you to download files bypassing the browser’s system filters.

This is especially true for sites that are labeled as “unsafe” by the security system due to lack of security. SSL-certificate or availability of advertising.

Special Opportunities and Access for Installators

In modern versions of Android and its shells, there is a mechanism that requires special permission to install applications from unknown sources. Xiaomi adds on top of this another level of control that can be adjusted through the special features menu.

You need to go to Settings → Applications → Application Management. You need to find three dots in the upper right corner and select "Special Access" (or "Other Permissions").

This menu lists all the programs that can initiate the installation (browsers, file managers, instant messengers) and select the file manager or browser you use and allow it to be installed. This is a basic requirement of Android, without which further action is impossible.

Once the permissions are set, the system will stop blocking the installation process itself, but may continue to show risk warnings. This is normal operating system behavior, but it does not prevent the procedure from being completed if you confirm the action.

Using ADB to Advance Disconnect

For users who want to remove the verification component, there is a method using USB debugging and the command line ADB (Android Debug Bridge), which requires connecting the smartphone to the computer and having minimal technical skills, but gives the most complete control over the system.

First, you need to activate the developer mode. You need to quickly click on the build number in the About Phone section 7 times. Then, in the Developer menu that appears, turn on the USB Debugging option. Connect the phone to your PC and start the ADB console.

To disable the system security scanner, a command is used that "freezes" the corresponding package, which does not physically remove it, but makes it non-functional, which excludes any checks during installation.

adb shell pm disable-user --user 0 com.miui.securityscan

You can also disable components responsible for recommendations and advertising in the security system:

adb shell pm disable-user --user 0 com.miui.misys


adb shell pm disable-user --user 0 com.android.ads

⚠️ Attention: Use of teams ADB Disabling critical system packages can cause an interface to function unstable or security functionality to be lost. Always check packet names before entering.

If you want to get back to the old days after you use the command adb shell pm enable com.miui.securityscan, which will restore the scanner to normal, and this method is especially effective on HyperOS devices, where standard settings can be hidden or limited.

Solving problems with Google Play Protect

Even after disabling all Xiaomi settings, the user may face a lockdown by Google itself.Play Protect is built into the app store and operates independently of the smartphone manufacturer.It can block the installation of apps that have not been certified by Google.

To disable this check, open the Google Play Store app. Click on the profile avatar in the upper right corner and select Play Protection. In the menu that opens, click on the settings gear and turn off the "Check Apps with Play Protection" option.

This will completely stop background checks of the installed APK-However, it is worth considering that this reduces the overall level of security of the device, since you disable one of the main mechanisms of protecting the Android ecosystem from malware.

In some cases, cleaning the cache of the Packet Installer app itself helps. Go to Settings → Apps → All apps, search the Package Installer list and click Clear Data and Clear Cache, which will reset possible caching errors that can cause false locks.
