Xiaomi, Redmi and POCO smartphone owners often face a mysterious process in their list of apps they have launched, called MSA or com.miui.msa.global, which raises questions among users, especially those who monitor resource consumption and data privacy, and many are immediately looking for ways to remove or freeze this process, considering it malicious.
But there's no rush to take radical action. MSA (MIUI System Ads) is not a virus, but a system service built into the shell of MIUI and HyperOS. It is responsible for displaying ads in the company's regular applications. Understanding the principles of this module will help you make an informed decision about its future fate on your device.
In this article, we will discuss in detail what this service is responsible for, why it is so deeply integrated into the system, and what safe ways to manage its activity are available, and how to turn off personalized advertising without using root rights and third-party software, while maintaining the stability of the operating system.
Decoding of the abbreviation and the purpose of the service
MSA stands for MIUI System Ads, a system component that is part of the Xiaomi ecosystem, and the main purpose of this process is to collect and analyze user data to create personalized advertising content, and it is thanks to this module that you see recommendations in the Music app, Security app, or in a standard browser.
It's important to understand that this is not a separate application that can be simply removed through a standard manager, but a background service that is closely related to the system processes of the shell, and its removal or forced shutdown can lead to unpredictable interface behavior or errors in the work of the regular utilities.
Technical details of the MSA process
It's worth noting that having this service is one of the reasons why Xiaomi smartphones are often sold at a very competitive price: the company compensates for the low margins of hardware through software advertising. By disabling MSA, you're effectively abandoning part of the manufacturer's business model, which can sometimes lead to conflicts in the software.

MSA is a legal system process responsible for displaying ads in the MIUI/HyperOS interface, not malware.
Impact on productivity and battery
One of the main questions that users are concerned about is: how much does com.miui.msa.global load the processor and drain the battery? In normal mode, when the ads are turned off in the settings, the resource consumption of this process is minimal, and it should not significantly affect the autonomy of a modern smartphone.
However, there are times when the process starts to behave incorrectly, which can be manifested in heating the case in standby mode or a sharp drop in battery power, most often due to cache errors or conflicts after updating the firmware.
- 📉 High traffic costs: If you notice that MSA consuming a lot of internet traffic, this may indicate an attempt to download new advertising modules.
- 🔋 Background discharge: The process can wake the device to retrieve data, which interferes with the system's deep sleep.
- 🐌 Brake: In rare cases, the service may call interface lags when opening system menus.
If you experience these symptoms, it is recommended to check for system updates or reset your ad settings, which in most cases returns your resource consumption to normal without the need for complex manipulation.
💡
To check the actual effect of MSA on the battery, go to Settings → Battery and see the flow statistics for the last 7 days. If the process is large, you need intervention.
Should I Remove MSA: The Pros and Cons of
The decision to remove or disable the MSA is made by each user independently, weighing all the pros and cons. On the one hand, getting rid of advertising makes using the smartphone more comfortable and enjoyable, on the other hand, interference with system processes always carries risks.
So here's a basic argument that will help you decide, and if you value the cleanliness of the interface and you're willing to spend time fine-tuning it, turning off the ads is a logical step, but if you want to be absolutely stable out of the box, you'd better limit yourself to minimal privacy settings.
| Criteria | With MSA on | With MSA disabled |
|---|---|---|
| Advertising in the system | Present. | Absent. |
| Stability of the PRO | Maximum | Rare disruptions possible |
| Confidentiality | Data collection active | Data collection minimized |
| Difficulty setting up | Not required | It takes time. |
Therefore, the “golden mean” is not the removal, but the competent disabling of the functions of data collection and displaying ads.
How to Disable Advertising Without Deleting the Process
The safest and most appropriate way to combat intrusive ads is to use Xiaomi’s built-in tools, which include the ability to disable ad personalization, effectively neutralizing the MSA without violating system integrity.
First, you go to the password and security settings menu, and there's a key switch that prevents the system from using your data for targeted advertising, which is the first and most important step.
Settings → Passwords and Security → Privacy → Advertising Services → Disable Personal AdvertisingNext, you should check the settings of each system application separately. Security, Downloads, Music, and Themes often have their own recommendation switches. Disable them all for maximum effect.
☑️ Checklist for disabling ads
⚠️ Warning: After personalization is turned off, ads may not disappear completely, but they may become less relevant and intrusive.
Forced suspension and restriction of rights
If the standard settings don't work, you can try tougher measures, which are to restrict the background activity of the com.miui.msa.global process, which won't delete the file, but will prevent it from running without your knowledge.
Go to the application management menu and find the listing “MSA” or “Advertising Services.” Here you need to find “Other permissions” or “Additional.” In this section, disable network, location and autorun access.
- 🚫 Auto Start: Prevent the application from running with the system.
- 📶 Access to the Internet: Without the Internet, the process will not be able to download the banner ad.
- 🔔 Notifications: Completely disallow the withdrawal of any notifications from this service.
It is also useful to clean up the data and cache of the application.This will reset the accumulated temporary files that can cause errors. However, keep in mind that after a reboot, the system may again try to activate the service.
What happens if you cut off access to the network?
Using ADB for Advanced Users
For those who are not afraid of the command line, there is a method of disabling through ADB (Android Debug Bridge), which allows you to “freeze” the system application for the current user without removing it physically from the /system partition.
You'll need a computer, USB-cable and installed drivers ADB. After the debugging is activated, USB on a smartphone, connect it to a PC and enter a command to remove the packet for the current user.
adb shell pm uninstall -k --user 0 com.miui.msa.globalThis command will hide the application from the system. It will stop running and consuming resources. If you want to return everything as it was, just execute the command cmd package install-existing com.miui.msa.global or simply reset the phone to the factory settings.
⚠️ Be very careful when putting commands into ADB. Removal of critical system components (not only) MSA) This can lead to a cyclical reboot (bootloop).
This is considered the most effective method among the safest, and it allows you to achieve a result comparable to root rights, but without the need to unlock the bootloader, which preserves the warranty on the device.
