MSA on Xiaomi: what is it and how to disable it

Xiaomi smartphone owners often encounter a mysterious process called msa in the list of running apps or in data usage statistics. When trying to find information about what it is, users encounter conflicting opinions, from system necessity to malicious virus. In fact, msa stands for MIUI System Ads and is the official service for displaying advertising in the MIUI interface.

This system service is responsible for collecting your preferences and displaying banner ads in standard applications. Many users wonder whether it is safe to forcefully stop or remove this process. In this article, we will discuss the functionality of the service in detail, assess the risks of turning it off, and provide step-by-step instructions for blocking intrusive advertising.

Main purpose of MSA service

MIUI System Ads is integrated into the MIUI shell along with other system processes, with the primary goal of analyzing user behavior and generating personalized results from the data, enabling Xiaomi to subsidize the cost of its devices by offering hardware at a more competitive price.

It runs in the background and periodically accesses servers to receive relevant advertising campaigns, and it can be activated when you open standard applications such as Explorer, Music or Themes. It is important to understand that this is not a virus, but a legitimate component of the operating system, although it causes many questions for advanced users.

It’s worth noting that in different regions, firmware can behave differently: in Chinese versions of ROM, advertising is often more aggressive, whereas in Global versions, its amount depends on the account settings and the specific smartphone model. Disabling the service will not disrupt the basic functions of the phone, but can affect the personalization of some system offers.

Where advertising occurs and how it affects the system

The msa ad engine is present in various corners of the MIUI interface, and most often, users notice banners in application folders, notification curtains, or when they unlock the screen, and ads can pop up after installing new apps from the GetApps store.

The impact on system performance is usually minimal, but in the background, the service consumes Internet traffic and battery power. On older smartphones, active advertising modules can lead to small delays in the interface.

In addition to visual noise, the service collects anonymized data about which apps you use most, which is necessary for targeting algorithms, and if you're concerned about privacy, turning this feature off becomes a priority step in setting up your device.

Is it safe to turn off the MSA?

The issue of the safety of disabling MIUI System Ads worries many: officially the manufacturer does not recommend interfering with the work of system processes, but practice shows that forced stopping or deleting service through ADB does not lead to critical errors (bootloop or cyclic reboot).

⚠️ Attention: Before any manipulation of system applications, it is strongly recommended to create a complete backup of data. Although the risk is minimal, human factors or bugs in a particular firmware version can lead to unstable operation.

Once you disable the service, you will no longer see ads in system applications, which will positively affect the speed of the interface, but some features associated with content recommendations (for example, the news feed in the Security app) may stop updating or display empty fields.

It is important to distinguish between disabling through settings (which is safe) and completely removing system APK-file (which requires root rights or ADB For most users, it is enough to simply deny access to data and stop the process.

Method 1: Disconnection through smartphone settings

The easiest and safest way to combat intrusive notifications is to use the built-in MIUI tools, which do not require a computer connection or special knowledge, and you first need to turn off personalization of advertising in your account.

Go to Settings, then look for Password and Security, and you're interested in Access to Personal Data or Special Features (the name may vary depending on the Android version), find the msa list and turn the switch to "Off" and the system will require you to wait 10 seconds, after which it will confirm the action.

Then you turn off the recommendation in the apps themselves. Go to the Security app, click on the settings gear in the corner, and find Receive recommendations by turning it off. Similar actions can be done in the Topics, Music, and Explorer apps through their internal settings.

💡

Tip: After disabling the msa service through settings, rebooting the device is mandatory for complete termination of background processes and cleaning the ad cache.

Method 2: Using ADB for Advanced Users

If standard methods don't help or you want to uninstall the service, you can use the Android Debug Bridge (ADB) tool, which requires a computer and enabled USB debugging on your smartphone, and allows you to uninstall system applications without obtaining root rights.

To start, turn on the About Phone Developer menu by activating the build number 7 times. Then turn on USB Debugging from the developer menu. Connect the phone to your PC, install drivers and ADB. In the command line, enter the following command to delete the package:

adb shell pm uninstall -k --user 0 com.miui.msa.global

This command will remove the user installation of the msa package for the current user, in fact deaktiviruya it.The system will continue to work stable, but the ad module will be completely excluded from the download process. To return everything as it was, use the command adb shell cmd package install-existing com.miui.msa.global.

Additional protection measures

In addition to fighting msa, you should pay attention to other data-gathering services. At Xiaomi, analytics is often the responsibility of the Analytics process. It can also be found in the list of applications and restrict its access to data or disable it through ADB using the batch name com.miui.analytics.

It is also recommended to check the permissions for Google's voice assistant and Mi AI. Often they have access to the microphone and location permanently. Limiting these rights to background work or using only when opening the application will increase the overall level of privacy.

• 📱 Regularly check the list of applications with access to the advertising ID.
• 🔒 Use it. DNS Ad-blocking (e.g. AdGuard) DNS) privately DNS.
• 🚫 Turn off automatic updates for system applications if you don’t trust the new features.

💡

An integrated approach including disabling msa, analytics and use DNS-filters, ensures maximum purity of the system and no advertising.
