MSA on Xiaomi: what kind of program is it and whether it should be removed

Owners of Xiaomi, Redmi and Poco smartphones often notice a mysterious system component called msa in the list of running processes or the Security app. This process can consume traffic, appear in notifications or simply annoy with its presence in the task manager, causing users to search for information about its purpose.

MSA stands for MIUI System Ads (or MIUI System Service), which directly indicates its connection to the manufacturer’s advertising ecosystem, and is essentially a built-in service that collects analytics about user behavior and targeted advertising within the system applications of the MIUI shell and HyperOS.

Many users mistakenly believe it is a virus or malware, but msa is a legitimate part of the firmware, and yet its work often raises questions because of its high battery and internet consumption, and the intrusive nature of the promotional offers it broadcasts on the smartphone interface.

The main purpose of the MSA system process

The main purpose of this component is to ensure that the company’s advertising platform works, and when you see a recommendation to install a game in the Downloads menu, a banner in the Music app, or an offer to subscribe to the Topics, msa is responsible for displaying this content, and it collects data about your preferences to show more relevant ads.

It also collects data on how you use your device, analyzes which apps you open more often, how much time you spend on your phone, and how you interact with the interface, and sends it to the manufacturer’s servers to improve user experience and monetize the device, as Xiaomi often sells smartphones at a minimal margin, offsetting costs from services.

⚠️ Warning: Complete removal of the system file may lead to unstable shell operation MIUI. In some cases, this causes errors in the operation of standard applications, such as “Security” or “Conductor».

It's important to understand that msa is very integrated into the system. It's not just showing pictures, it's also responsible for updating the ad units. If you've never seen a pop-up, it doesn't mean that the process isn't working -- it can just collect data in the background, waiting for the right moment to show content.

Why MSA is wasting traffic and battery

One of the most common complaints users have is the high cost of resources. Because msa is in the background, it's constantly active. Its main function is to download relevant advertising content, which requires a constant connection to the Internet. Even if you don't see ads right now, the process can download new banners or send data packets to telemetry.

Battery consumption is related to the frequency of the CPU and communication module. Every time a service collects data about an application or location that is running, it wakes up the device. On older models of smartphones or with a weak network signal, this process can be especially noticeable, since the communication module operates at increased power.

• 📶 Background synchronization: Constant transfer of user activity data to analytics servers.
• 🖼️ Media Download: Downloading images and videos for ad integrations in the system menu.
• 📍 Geolocation: Periodic coordinate request for displaying targeted offers nearby.

If you notice that msa consumes too much power, it may indicate a service failure or conflict with other applications. In the normal state, its impact on autonomy should be minimal, but it is not completely invisible.

💡

To reduce battery consumption, try to limit the background activity of the process through the application settings without removing it completely.

Is it safe to remove MSA on Android?

The issue of security removal of msa is a concern for many. From a technical point of view, disabling this process will not harm the hardware of your smartphone. However, since it is a system component, its forced termination or removal through root rights can lead to software errors. The MIUI shell can begin to issue notifications of failures or even go into a cyclical reboot in rare cases.

The safest method is not to remove, but to disable through special settings or ADB-This allows you to freeze the process, keeping the integrity of the system files. In this state, msa does not start, collect data, and show ads, but the system believes that the component is present.

It’s worth noting that once you update your firmware, your settings may reset and the service will be activated again, so if you decide to fight it with radical methods, be prepared to repeat the procedure after each major system update.

How to Disable Advertising and MSA Through Settings

The easiest and most affordable way to reduce msa activity is to use built-in shell tools. In modern versions of MIUI and HyperOS, developers have added the ability to turn off personalized advertising, which will not remove the process completely, but will deprive it of meaning, since collecting data for targeting will be prohibited.

First, you need to go to the password and security settings menu, find the privacy or special features section, and there's a personalization section, and if you turn off the switch, you'll stop the system from using your data to create an ad profile.

Settings → Passwords and Security → Privacy → Advertising → Disable Personalization

Next, you should go through each system application where advertising may appear: Music, Video, Explorer, Downloads and Themes, and in each of them you should find the option "Receive recommendations" or "Show ads" and deactivate it.

After doing this, msa will continue to work, but its activity will decrease significantly, it will stop downloading heavy media content and will less often access the network, which is the optimal balance between system stability and user comfort.

Radical methods: disabling through ADB

For more advanced users who want to stop the msa process completely, there is a method using USB debugging and a computer, which requires a PC, a cable, and minimal command-line knowledge, and allows the packet to be forcibly frozen for the current user without superuser rights.

First, you need to activate the developer mode on your smartphone, and then seven times click on the build number in the About Phone section, then turn on the USB Debugging menu in the Developer Menu, plug the phone into your computer, and install the ADB drivers.

Once connected, execute a command to disable the packet. It is important not to uninstall, but to disable it so that it can be easily retrieved in case of problems.

adb shell pm disable-user --user 0 com.miui.msa.global

⚠️ Attention: Use of teams ADB A mistake in the name of the package can cause critical system services to be disabled, making the phone inoperable.

If you notice strange behavior after shutdown, such as stopping menus or searching, the process can be easily reactivated by adb shell pm enable --user 0 com.miui.msa.global.

Impact of firmware updates on the service

Xiaomi regularly updates its devices, and with each new release of MIUI or HyperOS, the structure of system processes may change. In some versions, msa can be renamed or combined with other services, in others, its functionality can be expanded or, conversely, reduced.

Often, after a major system update, all manual restrictions are removed, and the operating system perceives this as the installation of “clean” software and returns the default settings, which means that you will have to re-go through the procedure of disabling advertising and checking permissions for msa.

Recent shells tend to integrate more nuanced ad modules, masquerading as analytics services or being broken down into a few smaller processes, making them difficult to identify and disable, and users should be careful when looking at the list of running processes after an update.

• 🔄 Resetting: Update often returns included ad toggles.
• 🆕 New Names: The process may be called differently in new versions of Android.
• 🛡️ System Protection: Modern Versions MIUI Can block attempts to disable system components.

It is recommended to check the privacy settings after each update.This will take a couple of minutes, but will ensure that the device runs smoothly without an unexpected spike in traffic or intrusive banners.

💡

Regularly checking your settings after updates is the only way to ensure your device is ad-free in the long run.
