Owners of Redmi and Poco smartphones often notice a mysterious process called MSA in the installed program list or in the Memory Use section. The appearance of an unknown element in the system is always a source of concern, especially given the reputation of MIUI shell as a platform with aggressive advertising policies. Users rightly wonder whether this is a hidden virus, a miner or spyware that steals personal data.
In fact, it's much more prosaic, though not without its unpleasant nuances: MSA stands for MIUI System Ads. As the name suggests, this system component is responsible for displaying ads in standard Xiaomi shell applications. It's not malicious code in the classical sense, but its activities directly affect the user experience, consuming traffic and battery resources.
Understanding the nature of this service is critical for those who want to clean up their gadget from intrusive advertising and speed up its operation. In this article, we will discuss in detail what exactly MIUI System Ads performs, why it consumes the Internet, and whether it should be forcibly stopped or removed. We will also look at safe ways to deactivate this component without the need to obtain Root rights.
Technical purpose of the system process MSAThe main objective of the process MSA It is a component of collecting analytics about user actions and then targeting advertising content. Unlike third-party applications that can be simply removed, this component is deeply integrated into the Android system services on Xiaomi devices. It runs in the background, constantly waiting for commands from the company's servers to display promotional materials, and it's worth noting that the ad engine isn't limited to pop-ups. It analyzes which apps you use most, which sites you visit and which search queries you type, and it generates a personalized offer that can appear on menus, when you unlock your screen, or in a standard file explorer. Technical details of the work MSAProcess MSA It uses standard Android services to access the installed list of applications and usage history, and it does not require special permissions, as it is part of the system signature. MIUI. Memory consumption varies from 50 to 200 MB depending on the activity of advertising campaigns. MIUI System Ads. If you see a process that consumes a huge amount of traffic in the background, it's not necessarily a bug. It's likely just downloading a new package of banner ads or videos to display in the interface. Disabling this feature is the first step to a clean installation. MIUI.
Where exactly does the user meet the MSA advertisement?
MSA is not limited to a single program, it permeates the entire ecosystem of standard Xiaomi applications, and users are most often exposed to the results of its work in the standard Security application, where, after scanning the system, recommendations for installing “useful” utilities or games can appear.
Other popular places to see advertising content generated by MSA include:
- 📂 File Explorer: In the “Recent” section or when you open certain folders, banners may appear with an offer to download an antivirus or optimizer.
- 🎵 Music and Video: When you run standard players, full-screen advertising is often displayed, which is difficult to close without accidentally clicking on the link.
- 📥 Downloads: Sometimes shortcuts to games or apps appear in the Download folder that the user did not install – this is the work of the advertising module.
- 🔒 Lock screen: The Glance feature is also closely linked to advertising services and uploads content through the same channels.
Special attention should be paid to the MIUI folder at the root of internal memory, which is often where temporary files, image cache and log files associated with the operation of the ad engine are stored, and periodic cleaning of this cache can temporarily reduce the activity of the process, but will not shut it down completely.
The impact of MSA on smartphone performance and autonomy
Although MIUI System Ads is not a virus, its presence negatively affects the resources of the device. The constant background process consumes RAM, which on budget Redmi models with 3-4 GB of memory can lead to more frequent unloading of background applications, this manifests itself in the form of interface twitches or longer opening programs.
In terms of autonomy, the impact is twofold: on the one hand, the process itself is not so heavy as to drain the battery in a couple of hours; on the other hand, constant requests to the network to update advertising content and geolocation requests prevent the processor and radio from going into deep sleep, as a result, the phone can discharge in standby mode faster than usual.
⚠️ Note: If you notice that the process MSA consume 10-15% If you charge your battery per day, this may indicate a malfunction of the advertising module or a conflict of versions, in this case, it is recommended to reset the ad settings or update the system components through the GetApps store.
Also worth mentioning is the consumption of Internet traffic. MSA downloads not only light text ads, but also heavy media files. If you use mobile Internet with a limited rate, background ad loading can be a nasty surprise at the end of the month.
Data security: risk of information leakage
The issue of privacy when using MIUI System Ads is especially acute, and for effective targeting, the service collects a vast pool of data: the list of installed applications, search history, location and even data about connected Wi-Fi networks, all of which are transmitted to the servers of Xiaomi and partners of the advertising network.
While the company claims to have adhered to privacy policies, the mere fact of collecting data without the user’s explicit consent (besides accepting general terms when first set up) raises questions from cybersecurity experts: Deleting or disabling the MSA significantly increases the privacy of smartphone use, limiting the flow of outgoing information.
| Parameter | With MSA on | With MSA disabled | Influence on the user |
|---|---|---|---|
| Data collection | Complete (applications, geolocation, habits) | Minimum (system logs only) | Increasing privacy |
| Traffic. | High (downloading media content) | Zero (system only) | Saving traffic and money |
| CPU load | Periodic jumps when downloading advertising | Stable low. | Less heat, higher speed. |
| Irritants | Pop-ups, banners | Absent. | Comfortable use |

Disabling the MSA does not disrupt the smartphone, but it makes the system much cleaner and safer from a privacy perspective.
How to disable advertising system means MIUI
Before you resort to radical measures like shutting down system processes, it’s worth trying the legal methods Xiaomi’s developers have in mind: they don’t remove the MSA completely, but they forbid it from showing ads, which is the safest way to do without installing third-party software.
The first step is to disable ad personalization. To do this, go to the Settings menu, find the Passwords and Security section (or Advanced Settings in older versions), then select Access to Personal Data. In the list, find the msa and turn off the switchboard. The system will ask you to wait 10 seconds and confirm the action.
☑️ Checklist of ad-shutdown
Next, you need to go through each system application separately. In Security, Downloads, Music, and Topics, find the settings (usually in the upper right corner or in the three-dot menu) and uncheck the box from Get Recommendations or Show Ads. This action breaks the link between the application interface and the ad server.
It's also a good idea to turn off the Glance feature if you're not using it. It's in Wallpaper → Wallpaper Carousel settings. Disabling this service also reduces the load on the MSA process, as they often work together.
Radical methods: Disconnection through ADB and Debloat
If standard settings don't work or you want to completely remove MIUI System Ads from your system, you'll have to use debugging tools. The most efficient and safe method is to use ADB (Android Debug Bridge) from your computer, which allows you to remove system applications without Root permissions.
First, you need to activate the developer mode. Go to Settings. → About the phone and 7 times click on the version MIUI. Then, in the extended settings, turn on USB-Debugging. Connect your phone to your PC and execute a command to delete the packet:
adb shell pm uninstall -k --user 0 com.miui.misysHowever, be careful: completely removing system components can lead to unstable shell operation, for example, widgets or notifications may stop working, and a milder option is simply to freeze the application, preventing it from running.
⚠️ Attention: Before use ADB-commands are strongly recommended to make a full backup of important data. Incorrect removal of system packages can lead to a cyclic restart (bootloop) of the device.
💡
Use the Xiaomi ADB/Fastboot Tools utility for Windows – it has a graphical interface and allows you to safely remove MSA and other advertising services with a single button, marking them as “Uninstall”.
