Code 447491163442 on Xiaomi: how to disable and delete

Users of Xiaomi smartphones and TVs often encounter mysterious notifications or processes in the task manager containing long numerical sequences, such as 447491163442.This is not a system kernel error, but a specific identifier of an advertising module or MIUI analytics service that is activated without the knowledge of the owner of the device. The appearance of such code is often accompanied by the sudden appearance of banners on the desktop or in the notification curtain, which critically reduces the comfort of using the gadget.

This process cannot be ignored, as it consumes CPU traffic and resources in the background. Device owners need to understand that the digital ID is part of the MSA (MIUI System Ads) ecosystem, which is built into the shell by default to monetize budget devices. In this guide, we will detail how to safely deactivate intrusive services without obtaining superuser rights.

There are several layers of protection, ranging from simple menu settings to advanced methods through USB debugging. It is important to act consistently, as a one-time shutdown of all services can lead to unstable operation of some system applications. Below is a detailed guide to help you regain control of the device.

The nature of the appearance of a numerical identifier in the system

The number sequence 447491163442 is not a random set of numbers, but a hash sum or unique ID of a particular ad plugin embedded in HyperOS or MIUI. Developers use such identifiers to dynamically load content from servers, allowing you to change advertising campaigns without updating the entire operating system. When you see this code in the list of running applications, this means that there is an active synchronization or attempt to display the targeted offer.

The main problem is that this process is disguised as system-based so that the user can not easily complete or delete it with standard means, often associated with pre-installed applications like GetApps, Mi Browser or the Tools system folder. If you do not limit its activity, the device can start to consume more power, and the battery will run out faster even in standby mode.

⚠️ Note: Attempting to delete system files associated with this code through a root file manager can result in a cyclic device restart (bootloop.

It's worth noting that code can change when you update your firmware, but the way it works remains the same: It's embedded deep in Android processes, using legitimate system permissions to display on top of other windows, which is why conventional antiviruses often label it as "potentially undesirable," but don't block it, considering it part of the manufacturer's official shell.

Basic MIUI privacy setting

The first and safest step is to disable the customization of ads through the standard settings menu, which will not completely remove the ad engine, but will prevent it from collecting data about your activities and reduce the frequency of intrusive windows. You need to find a section responsible for security and privacy, which can be called differently in different versions of MIUI.

Go to your phone's settings and find "Password and Security." Inside this section, look for the "Privacy" or "Special Opportunities" tab, and there's a switch that formally consents to personalized recommendations, and disabling this option breaks the connection between your Mi Account and the company's ad servers.

• 📱 Go to Settings. → Password and security → Confidentiality.
• 🔍 Find the item “Advertising Services” or “Get recommendations».
• 🚫 Transfer the slider to the "Off" position and confirm the action.
• 🔄 Wait for the timer (usually 10 seconds) and click Stop».

After these steps are done, the system may need to restart, which is a normal reaction, since changes only take effect after restarting system services, but if code 447491163442 continues to appear, then a deeper intervention in the work of specific source applications is required.

💡

Before you make changes to your privacy settings, take a screenshot of the current settings, which will help you quickly get things back to normal if your weather widgets or news feeds stop working after you turn off the ad.

Disabling system source applications

The most effective way to combat intrusiveness is to force notifications to stop and disable notifications for applications that most often serve as triggers. Statistics show that code 447491163442 is most often generated by MSA services, MIUI Daemon or an embedded browser.

To do this, go to the application management menu, and it's important to be careful: some system processes are hidden by default, and you may need to enable all applications, including system applications, to be displayed through the three-dot menu in the upper right corner of the screen. Find the msa app in the list (MIUI System Ads).

Once you log in to the msa properties, you need to do a series of actions. First, turn off notifications to remove visual spam. Then click on Stop or Force Stop. Immediately after that, until the process has restarted, you need to turn off the AutoStart slider and, if available, click Disable (Gray App). If the Shutdown button is inactive, go to the Permissions section and revoke access to the network and storage.

A similar procedure should be done for GetApps and MIUI Daemon, which often work together. In some regions (for example, in global firmware for Russia), the complete removal of msa is impossible without a computer, but the restriction of rights makes it useless.

Use of Developer Mode and ADB

If standard methods didn’t get rid of the 447491163442 process, you’ll have to resort to more powerful tools: Developer mode allows you to access hidden settings, and ADB (Android Debug Bridge) utility allows you to delete or freeze system packages from your computer, which is the most radical, but also the most effective way.

To start, activate the developer mode. To do this, quickly click on the build number in the About Phone section seven times. Once you have become a developer, go back to the main settings menu, find the Additionals section and open the Developers section. Here you need to activate the USB Debugging switch.

adb shell pm disable-user --user 0 com.miui.msa.global

Connect your smartphone to your computer with a cable. The computer must have Platform-Tools installed. Open the command line in the ADB folder and enter a command to disable the advertising service. Note that the name of the package may vary depending on the firmware region (for example, com.miui.msa.global or com.miui.msa). Once you enter the command, the application will disappear from the installed list, but will remain in the system in case of a reset.

💡

Use of the ADB-commands allow you to “freeze” the ad module at the system level, which makes it impossible to start it even after a reboot, until you manually restore it yourself.

In addition to the advertising module, you can turn off other heavy processes through ADB. However, be extremely careful: removing critical system components (for example, com.android.phone) will cause the device to fail. Always check the name of the package on the Internet before entering the pm disable-user command.

Analysis of network activity and blocking

The current approach to combating telemetry and ad codes involves blocking network requests. Even if the process 447491163442 is running, it will not be able to transmit data or receive an ad command if it does not have access to Xiaomi servers, which can be implemented through DNS settings or third-party firewalls.

The easiest way is to change. DNS-server settings in Wi-Fi or mobile network settings using services like AdGuard DNS or NextDNS allows you to filter traffic at the provider level. DNS) Please write the address dns.adguard.com. This action will block requests to known advertising domains.

• 🌐 Open the Settings. → Wi-Fi and Internet → Private DNS.
• 🔑 Select the mode "Host Name provider».
• 📝 Enter the value of dns.adguard.com and save.
• ✅ Check the connection: the Internet should work, but ads in the browser and applications will disappear.

Alternatively, you can install a local firewall like NetGuard, which doesn't require root rights and creates a local firewall. VPN-In NetGuard, you can find a suspicious behavior process (high volume of outgoing traffic in the background) and deny it access to the network, leaving Internet access to other programs.

⚠️ Note: When blocking system domains through DNS function MIUI, These things, such as syncing themes, voice assistants, or weather updates, may stop functioning properly.

Prevention and additional safety measures

After successfully disabling code 447491163442, it is important to secure the result and prevent it from reappearing. MIUI or HyperOS firmware updates often return default settings, including activating advertising services. Regularly checking privacy settings should become a habit.

It is also recommended to disable the Receive References feature in each system application separately. Go to the Security, Music, Video and Themes settings, each with its own switch that displays news feeds or banner ads, and disabling them creates layered protection.

Also, watch for access rights to installed applications. Often, third-party software downloaded from unreliable sources can reactivate ad modules or install its own counterparts that masquerade as system processes. Use only trusted app stores such as Google Play or official GetApps (with caution).

If you notice that the code reappears after you upgrade, repeat the disabling procedure. In some cases, cleaning the cache of Google Play and Google Play services helps, as they can cache old configuration files that run advertising modules.
