MSA on Xiaomi: the purpose of the service and ways to disable

Xiaomi smartphone owners often encounter a mysterious process called MSA, which is found in the list of running applications or when trying to disable system services. The acronym raises questions from users who fear for the security of their data or just want to optimize the operation of the device. In fact, it is not a virus or malware, but an embedded system component responsible for showing advertising content in the interface of the MIUI shell.

Understanding the nature of this process allows you to effectively manage the resources of the gadget. Many users are eager to disable MIUI System Ads to get rid of intrusive banners in standard applications such as Music, Explorer or Themes. In this article, we will discuss in detail the functionality of the service, its effect on the battery and provide step-by-step instructions for deactivating it.

It's worth noting that removing the system component completely is impossible without obtaining the rights of the Root superuser, which can lead to a loss of warranty. However, properly configuring permissions allows you to reduce the activity of the service to zero. It is a safe method that does not violate the integrity of the Android operating system, but significantly improves the user experience.

Decoding of the abbreviation and appointment

MSA stands for MIUI System Ads, a system service developed by Xiaomi to integrate ad units into the smartphone interface, which is designed to analyze user actions and display targeted offers across different sections of the shell, and operates in the background, which can sometimes raise questions about battery consumption.

Unlike third-party ad modules, which are often embedded in free apps, MSA is part of the firmware. disabling MSA does not affect the operation of the basic functions of the phone, calls or mobile Internet. However, some built-in widgets, such as Horoscope or News on the desktop, may stop updating content, since they are also tied to advertising servers.

⚠️ Note: Attempting to delete the file MSA.apk through a file manager without root rights is impossible and can lead to system errors. Use only standard methods of disabling through settings.

Developers are implementing this mechanism to compensate for the low cost of devices, and when buying a budget smartphone, the user actually agrees to display ads in exchange for available hardware, but for many, having system advertising is a critical drawback that you want to get rid of immediately after buying.

Impact on productivity and battery

The impact of system advertising on smartphone autonomy remains a controversial issue: on the one hand, the msa process consumes minimal resources if the Internet connection is stable and the loading of ad units is fast, and in ideal conditions, the user may not even notice its presence in the task manager.

On the other hand, with weak network signal or overloaded Xiaomi servers, the service can go into a cycle of constant connection attempts, which leads to heating of the processor and accelerated battery discharge, especially on older smartphones, where every percentage of charge counts.

To assess the impact of the service on your device, you can use the statistics on energy consumption. Go to the settings and select Battery and Performance. Find the MSA application or System Services in the list. If the consumption exceeds 2-3% per day when you are actively using, it is recommended to limit its background activity.

💡

Use the “Energy Saving” mode at night – it automatically limits background activity of advertising services, saving charge for important notifications.

Also worth considering is the indirect impact on performance: the constant loading of heavy graphic banners can cause micro-latency when switching between windows or opening menus. Disabling the service often makes the MIUI interface more responsive and “volatile.”

How to disable MSA through smartphone settings

The easiest and safest way to stop adverts from showing is to use the system's built-in tools, which don't require a computer connection or third-party software installation, you'll only need Internet access to log into the settings menu, but the disconnection process itself happens locally.

First, you need to find the recommendation switch. The path may vary slightly depending on the version of MIUI, but the overall logic remains the same. Open the Settings app, then go to Passwords and Security (or Advanced Settings) and find Personal Data Access or Authorization and Recovery.

In the list of system services that opens, find the msa line. The slider next to it will be located. Press it, and the system will warn you about the consequences of a shutdown. A 10 second countdown timer will appear. Once it is completed, confirm the action with the recall button.

It is important to perform this procedure carefully, because the slider can return to its original position the first time. If it happens, repeat the procedure. Sometimes you need to wait a couple of minutes before you try again, so that the servers have time to update the status of the device.

Disabling Advertising in System Applications

Even after the permissions of msa are revoked, individual applications can continue to show ad units because they have their own recommendations settings. To completely clean the interface, you need to go through key system utilities.

First of all, look at the Security app. It often contains banners in the memory cleanup or antivirus section. Go to the app settings (the gear icon in the corner), find Receive recommendations and turn it off. Similar steps should be taken for the Themes, Music and Video app.

The algorithm is similar for Explorer and Downloads, and open the app, click on the menu (three dots or bars), select Settings, and uncheck the Recommends Show box, which will remove the news feed and promotional offers that often appear on the home screen of these utilities.

Also, remember to check the launcher settings. In the Themes app, go to profile, then to settings, and disable all items related to personalization and advertising, which will prevent the appearance of advertising carousels on the desktop.

Blocking through DNS and third-party solutions

If standard methods have not given full results or you want to guarantee a lock at the network level, you can use the system. DNS-This method redirects requests to ad servers to nowhere without downloading content to the device.

Modern versions of Android (9.0 and higher) have a built-in private DNS feature. Go to Settings → Connection and Compatibility (or “Other Connections”) → Private DNS. Select the DNS Provider Host Name mode and enter the address: dns.adguard.com. Save settings.

⚠️ Attention: Use of third-party DNS It can slow down some sites or disrupt local networks (such as Chromecasts or printers). If you have problems, return the setting to Auto mode. Alternatively, install specialized blockers such as Blokada or AdGuard. These applications create local VPN-They do require a permanent permit to work in the background, which can also consume an extra battery charge. DNS Does it not work? if it is after the switch? DNS Internet stopped working, check the correct spelling of the address dns.adguard.com. Also, some operators may block third-party DNS. In this case, try an alternative address: dns.adguard-family.com, which also blocks adult content. The process of deactivating system services does not always go smoothly. Users may face various restrictions imposed by the developers of MIUI. Understanding these nuances will help avoid unnecessary nerves and loss of time. One of the common problems is the automatic re-enablement of the msa slider. This happens if the device is active synchronization of settings through the Mi Cloud account. When authorized, the system can restore previous configurations, including permission to display ads. Also, users often confuse the msa process with Google Play or MIUI Daemon system services. Disabling the latter can lead to unstable operation of the msa from applications or from the store. 💡If a slider MSA It's always back to "On," try turning off the Internet before you press "Cancel," and then turn off the slider. In some cases, after you update the firmware, all settings may reset. This is normal behavior in major Android updates. It is recommended to check the ad settings after each major system update (FAQ) Is it safe to turn off completely? MSA Xiaomi? Yes, it's safe. Disabling msa won't cause your phone to break or your personal data to go missing. The only consequence is that there's no advertising in the system applications, and the call, message and app functions are not affected. Why does the ad still appear after the shutdown? Ads can come not only from the msa service, but also from other system applications such as Security, Themes or Downloads». You need to go to the settings of each of these applications separately and turn off the "Get recommendations" option. MSA Without Root rights, you can't physically delete the system file. ADB You can only disable the current user component (pm disable-user), but when reset to factory settings, it will return. Complete removal is only possible with the bootloader unlocked and the superuser rights. MSA Yes, horoscope, status, or desktop news feeds may stop updating or displaying empty cells, as their content is often downloaded from the same servers as the ads. MSA No, that's not necessary, the new owner will decide if he needs advertising services. Moreover, disabled advertising can be a plus for the buyer, who will appreciate the purity of the interface.
