MSA Process on Xiaomi: Assignment, Functions, and Disconnection

Xiaomi smartphone owners often face a mysterious name in the lists of running processes or when trying to disable system services. the acronym MSA (MIUI System Ads) raises many questions, as it is directly related to the display of advertising content in the shell of MIUI and HyperOS. Understanding the nature of this component is critical for those who want to clean the interface of intrusive banners.

At its core, it is not a virus or malware, but a standard operating system module developed by engineers at a Chinese corporation. However, its work can annoy users who are used to pure Android without unnecessary visual noise. In this article, we will examine the functionality of the service, its effect on the battery and provide step-by-step instructions for its deactivation.

It is worth noting that complete deletion of the system file is impossible without obtaining superuser rights (Root), which can lead to a loss of warranty. However, there are a number of effective methods to completely block the work of advertising hidden under this name.

Decoding of the abbreviation and appointment of the service

Name of name MSA is an abbreviation of the phrase MIUI System Ads. It is an embedded advertising service that is integrated deep into the software shell. MIUI. The main objective of this process is to collect anonymized data on user behavior for advertising targeting and its subsequent display in standard applications of the system. MSA responsible for pop-ups, banners in folders and recommendations in system utilities.

Many users mistakenly believe that this application can be simply removed through settings, like a regular program. However, since it is a system component, standard uninstallation methods do not work here. The process can automatically restart, if you do not disable the associated permissions and network activity. Understanding this mechanism is necessary to effectively combat intrusive content.

The service’s functionality is not limited to visual display of images, but also analyzes your actions in standard applications such as Explorer, Music, Security and Downloads, and this analytics generates a personalized offer that you see on the lock screen or in the GetApps app store interface.

• 📢 Collection of statistics on the use of standard applications for the formation of an advertising profile.
• 🖼️ Displaying banner ads in folders on the desktop and in the interface of the “cleaner».
• 🔄 Background update of advertising modules and cache for content update.

The impact of the process on the work of the smartphone

Having an active MSA process on a device has a direct impact on resource consumption. Although the file itself is not heavy, its constant activity in the background can lead to increased battery consumption, especially on older smartphone models, where the battery capacity is already small.

In addition to power consumption, the service uses Internet traffic to download promotional materials. If you are roaming or using a limited plan, background data transfer can be an unpleasant surprise at the end of the month.

⚠️ Warning: Attempting to force a process to stop through Task Manager without shutting down Internet access often leads to its automatic restart after a few minutes.

Constant requests to servers and rendering of advertising elements can create micro-latency in the interface. Disabling the service often makes the system work more smoothly, especially when switching between applications or opening menus.

Instructions to disable advertising through settings

The safest and most recommended way to deal with intrusive elements is to use built-in switches in the personalization menu, which requires no additional knowledge and is completely reversible, and first of all, you need to find the master switch responsible for obtaining recommendations.

Go to your device's settings menu. Find Password and Security or Advanced Settings (location may vary depending on the version of MIUI). Next, select Access to Personal Data or Authorization and Security. From the list of services, find msa and turn off the slider.

Once the slider is turned off, the system will ask you to wait 10 seconds and then confirm the action by pressing the Stop button, a security mechanism that prevents important system components from accidentally shutting down. If you agree with the consequences (no advertising), feel free to confirm the action.

However, disabling one service is not enough. Advertising can be broadcast through other system applications, and disabling Receive Recommends in the settings of each standard application, such as Topics, Music, Security and Explorer, will take a few minutes, but will provide a comprehensive result.

Blocking Internet access for system services

If a standard shutdown fails to produce the desired result or the Stop button is inactive, a more radical method can be used to deny the application access to the network, and without a connection to the server, the MSA will not be able to download banner ads, even if the process itself is started.

To implement this method, go to Settings → Applications → All apps. Find in the msa list (could be called “MIUI System Ads”). Select Data Use or Mobile Internet and Wi-Fi. Turn off both the mobile data and Wi-Fi switches.

This method is particularly effective when combined with the previous one, so even if the service tries to start, it will not be able to get the data to display, as a result, the user will see an empty space where the banner should have been, or the ads will not appear at all.

Using DNS to Block Advertising

More advanced users who want to clear all traffic on the device, not just system traffic, are encouraged to use personal DNS. This method does not require the installation of third-party applications and works at the network protocol level.

The most popular and effective solution is the use of the AdGuard service. DNS. To activate it, go to Settings → Connection and Sharing (or Wi-Fi). Find a Private Item DNS (Private DNS). Select the Host Name mode and enter the address: dns.adguard.com.

Once you save the settings, all requests to known ad servers will be blocked at the network level, not only for Xiaomi’s system advertising, but also for banners in browsers, games and other applications, which has little impact on Internet speed, but significantly improves the user experience.

• 🛡️ Blocking Trackers and Analytical Scripts in Applications.
• 🚫 Protection against switching to phishing sites through advertising networks.
• ⚡ Reducing the load on the processor due to the lack of processing of advertising code.

⚠️ Note: When using a third party DNS Some applications (such as carrier or banking) may not work properly if they block known applications. DNS-If you have a problem, just return the settings. DNS auto-mode».

Advanced Methods: ADB and System Change

For users with technical skills, it is possible to remove system packets through USB debugging (ADB), a method that allows you to completely cut out unnecessary components from the system, freeing up space and resources, but requires a computer and a cable.

You need to turn on the developer mode, activate debugging over USB and connect the smartphone to the PC. With the command line and the adb utility, you can send a command to delete or freeze the package. For example, the command to disable the service looks like this:

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

Use of such commands requires caution. Incorrect removal of the system component can lead to unstable interface operation or cyclic restloop. Always check the name of the package before entering the command.

💡

Before use ADB-commands be sure to make a full backup of the data, in case of a system failure, this will restore the functionality of the smartphone without losing information.

There are also graphical shells for ADB, such as Xiaomi ADB/Fastboot Tools or Universal Android Debloater. They simplify the process by providing a list of system applications with the ability to safely remove them with one click.

💡

The comprehensive approach (disabling the service + banning the Internet + DNS) gives a 100% guarantee of no advertising in the Xiaomi system.
