Owners of Xiaomi, Redmi and POCO smartphones often notice a mysterious process called msa on their installed list. When they try to remove or disable it, the system issues warnings about the possible unstable operation of the device, which causes legitimate alarm among users. Many people wonder whether this component is a virus, a hidden miner or a vital part of the MIUI operating system.
In fact, msa is an acronym for MIUI System Ads. As the name suggests, it's responsible for displaying advertising content in standard applications and system interfaces. It's because of this module that you see banner ads in folders, recommendations in the Security app, or pop-ups when you unlock the screen. Understanding its purpose is the first step to controlling your device.
In this article, we will take a closer look at the functionality of this component, find out how safe it is to completely disable it, and provide step-by-step instructions for setting up. Disabling MSA does not disrupt the basic functions of the phone, but can completely remove system advertising. You will learn to distinguish between system dependencies and intrusive marketing, and learn how to interfere with the work of system services.
The main purpose of the system component of the MSA
The msa service is integrated into the MIUI shell at a deep level and starts automatically when the operating system starts. Its main task is to collect anonymized data about user preferences for advertising targeting. The algorithm analyzes which applications you use more often, which sites you visit and which features you use to offer relevant content. This allows Xiaomi to subsidize the value of its devices, offering them at a competitive price.
But it's not just about displaying banners. It's also about running an App Vault that swipes to the left of the home screen, displays news, weather, steps, and, of course, promotional recommendations. Without an active msa process, these widgets can stop updating or displaying empty blocks. It's important to understand that this is not a virus, but a legitimate, though not always desirable, component of the firmware.
Users often confuse this process with system errors due to high power consumption in the background. Indeed, the constant collection of telemetry and loading of advertising modules can consume battery power. If you notice that the msa application is actively working when the phone is lying idle, this is the standard behavior for background synchronization of advertising profiles.
⚠️ Note: Complete removal of system applications through ADB This may result in loss of warranty or unstable interface operation.Be sure to understand the risks before making changes.
It’s worth noting that the global firmware (Global ROM) may have less impact than the Chinese versions, where the ads are stitched more aggressively, but it’s present on almost all modern models, whether the budget Redmi Note or the flagship Xiaomi 13.
Is it safe to remove or disable MSA?
The safety of disabling msa is a concern for many users. Technically, disabling this service will not cause a device to “brick” or make calls. Android will continue to function normally. However, because the component is deeply integrated into the shell, there may be specific side effects that you should be aware of in advance.
When you force the stop or delete, you may encounter the following changes in the interface:
- 📉 Widgets on the desktop and in the left menu will cease to be updated (weather, news, pedometer).
- 🚫 Recommendations in standard applications such as Music, Video and Conductor will disappear».
- 🔄 There may be periodic pop-up messages about the error "msa stopped" when booting the system.
- 🔋 Increased battery life due to the absence of background loading of advertising traffic.
If you prioritize cleanliness and no advertising, disabling msa is a justified step. Most users don't even notice the lack of features that are tied to this service, since the main messengers and social networks work independently of it.
💡
Before disabling system services, make a full backup of important data to the cloud service or computer so that you can roll back changes in the event of a failure.
Instructions for disabling advertising in the MIUI settings
Before resorting to radical measures like computer removal, it is worth trying built-in mechanisms to disable ads. This is the most secure method that does not require root rights or a PC connection. Xiaomi allows users to partially control the flow of advertising content through special switches.
The first step is to disable ad personalization. To do this, go to Settings → Passwords & Security → Data Access. Find msa and deny access to Wi-Fi and mobile data. This works by linking the application to the ad servers, although the process itself may continue to work locally.
Next is deaktivirovat' (disable service) MSA through the application menu. Find the App item in the settings → All applications, click three dots in the corner and select Show System. In the list, find msa and click Disable. The system will ask you to wait 10 seconds, then prompt you to confirm the action. If the button is inactive, try clearing the application data first.
☑️ Checklist of ad-shutdown
It is also recommended to disable ads in individual system utilities. Open the Security app, go to the settings (cogs) and find the item “Receive recommendations.” Similar settings are available in the download, music and topic apps. A comprehensive approach will ensure that the interface is as clean as possible from marketing noise.
Removing MSA via ADB for Advanced Users
If standard methods fail or you want to cut the ad package out of the system completely, you can use the tool. ADB (Android Debug Bridge: This method requires connecting your smartphone to your computer via a computer. USB-It allows you to remove system applications without superuser rights (Root), but requires care.
To start, activate Developer Mode. Go to Settings → About Phone and quickly click on MIUI build number seven times. Then, in the Developer Menu, turn on USB Debugging. Connect your phone to your PC, download the SDK Platform Tools platform, and open the command line in the tool folder.
adb devices
adb shell pm uninstall -k --user 0 com.miui.msa.globalThe first command will check the connection to the device, and the second will remove the msa packet for the current user. Note that the package may be called differently depending on the region: com.miui.msa.global for global versions or com.miui.msa for others. After completing the command, the ads should disappear completely, including system recommendations.
⚠️ Attention: When in use ADB-Be very precise in spelling the name of the package. Removing critical system components (such as framework-res) can cause a cyclical reboot of the phone.
To return everything as it was, you can use the recovery command: adb shell cmd package install-existing com.miui.msa.global. This is useful if after removal you notice the loss of important functions or instability of the interface.
Comparison of methods of combating system advertising
There are several approaches to solving the problem of intrusive marketing on Xiaomi devices. Each method has its advantages and disadvantages, which should be considered depending on your technical background and goals. Below is a comparative table of the main ways.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Disconnection in settings | Low. | Medium (remains traces) | Minimum |
| Network access ban | Low. | High (no loading) | Widgets don't work. |
| Removal via ADB | Tall. | Maximum (complete removal) | Possible system errors |
| Installation of custom firmware | Very high. | Absolute. | Loss of warranty, risk of brick |
For most users, the best option is to combine the network ban and the settings shutdown, which produces 95% of the result without the need to use a computer, and the ADB method should only be chosen by experienced users who understand what they are doing and are willing to reflash the device if necessary.
Using custom firmware (such as Xiaomi.eu or LineageOS) is a radical step that completely changes the operating system. In such builds, msa and other advertising modules are cut at the firmware code level, which provides better performance and autonomy, but requires unlocking the bootloader, which erases all data from the phone.
Effects of MSA on performance and battery
Many users are wondering how much msa affects smartphone performance: On modern Snapdragon or MediaTek processors, the load from one negligible background process (not much), but combined with other MIUI services (there are dozens of them), this module contributes to the overall load on RAM and processor.
More noticeable is the impact on battery consumption: Constant connection to ad servers, analysis of user actions and preparation for displaying banners require resources. On devices with a small battery (up to 4000 mAh), turning off msa can add from 30 minutes to an hour of screen life, this is especially true for older models where battery wear is already noticeable.
Why does MSA consume a lot of energy?
In addition, the lack of advertising modules frees up the Internet connection channel. If you are in a zone of poor coverage of 3G/4G, background loading of ads can significantly reduce the speed of loading pages in the browser or buffering videos.
💡
Disabling MSA is not only getting rid of visual noise, but also a real way to extend the life of a smartphone from a single charge.
Possible problems after disconnection and their solution
Despite the safety of the procedure, there are rare nuances, most often because some system components try to access a disabled service and get an error, usually solved by simply restarting the device, but sometimes additional actions are required.
If you have a weather or news widget that stops working after you turn off msa, try to clear the relevant app's data. For example, for a weather widget, go to Settings → Apps → Weather → Warehouse → Clean. After that, the widget should work, just stop showing promotional articles in the newsfeed.
If you have persistent pop-ups with the “msa app stopped” error, you can try freezing the app instead of completely shutting it down if you have Root rights or have specialized software installed like Titanium Backup. Freezing makes the application invisible to the system, but saves its files in case you need to restore it.
