MSA on Xiaomi Redmi 8: what is this process and whether it is worth turning it off

Owners of budget smartphones like the Xiaomi Redmi 8 often notice a strange process called msa in the list of running apps or in battery usage statistics. This reduction raises many questions among users who do not understand why the system needs this service and whether it is not a virus. In fact, it is the system component of the MIUI shell, which is responsible for displaying advertising content in standard applications.

While Redmi 8 is marketed as an affordable device, the company compensates for the low margins of hardware with software services. MSA (MIUI System Ads) is the mechanism that analyzes your actions and offers personalized offers. Understanding the operation of this module is necessary for any user who wants to clean the interface of unnecessary visual noise.

In this article, we will take a closer look at the function of the service, its impact on device performance, and how to manage it safely, and why removing it completely can lead to errors in the system, and what alternative ways to minimize its activity without obtaining root rights.

Many users mistakenly believe that turning off ads will instantly turn their smartphone into a flagship, but MSA is just one component of the ecosystem, and it is important to approach the setup in a comprehensive manner so as not to disrupt other system functions that depend on the company's network services.

Functional Assignment of MSA Service in MIUI

MSA stands for MIUI System Ads. It is a system application built deep into the MIUI shell, which is installed on the Xiaomi Redmi 8 by default. Its main task is to download and display banners, recommendation cards and promotional materials in various parts of the operating system.

It doesn't just show static images, it collects anonymized data about user preferences, app usage rates, and search queries, and it uses this analytics to generate personalized ads, and it allows the company to monetize the device by selling ads to third parties.

⚠️ Note: Complete removal of system files MSA Without a backup or deep knowledge of Android, it can cause a cyclical reboot of the device (bootloop).

Unlike regular applications, msa has higher privileges in the system: it can start automatically when the screen is turned on or the device is unlocked. In some versions of firmware, this process is responsible for the appearance of recommendations in the Tools folder and on the lock screen.

Process Impact on Redmi 8 Performance

Xiaomi Redmi 8 is equipped with a Snapdragon 439 processor and 3 or 4 GB of RAM, which are basic features for modern tasks. When the MSA background process begins to load content or analytics, it consumes the resources of the processor and the Internet channel.

Users often complain of sudden heat or reduced battery life. In battery statistics, you can see that the process of "Advertising Services" or msa consumes a significant percentage of energy, especially if the device is constantly connected to a Wi-Fi network or mobile Internet.

• 📉 Reduced speed of the interface when switching between applications.
• 🔋 Increased battery consumption in standby mode.
• 🌐 Increased mobile data traffic due to media content download.
• 📲 Appearance of pop-up windows in standard utilities (Conductor, Security).

Especially noticeable is the impact on older firmware versions, where optimizing background tasks was less effective. Disabling the service often leads to a subjective sense of “acceleration” of the smartphone, as part of the RAM and CPU cycles are released.

💡

To test the effect of MSA on your Redmi 8, open up battery stats for the past 24 hours. If the process takes more than 3-5%, turning it off will give you a tangible boost in battery life.

Can you remove the MSA from your phone?

The issue of completely removing msa is one of the most popular among Xiaomi owners. Standard system tools, through the settings menu or application manager, it is impossible to remove this component.

Advanced methods of deleting via ADB (Android Debug Bridge) from a computer or using superuser rights (Root) exist, but Xiaomi engineers have provided self-repair mechanisms. When restarting or updating system components, MIUI can automatically restore deleted files, returning ads to their place.

The safest and most recommended approach is not to remove, but to correctly configure and disable the personalization function, which allows you to maintain the stability of the Redmi 8, getting rid of intrusive banners.

Complete removal of system-specific APK-file ADB — For 95% of users, it is enough to simply disable the personalization of ads in the settings of the Mi Account.

Step-by-step: disabling advertising in settings

The first and most important step is to disable ad personalization, which doesn't completely remove ads, but makes them irrelevant and stops collecting your preferences, go to Settings, look for Passwords and Security (or Advanced Settings in older versions).

Next, select Access to Personal Data or Authorization and Privacy. In the list, look for msa and Mi Daemon. Switch the slider to Off. The system will alert you that certain features may stop working, a standard warning that can be ignored.

After turning off the slider, the system will ask you to wait 10 seconds so you don't do it accidentally. Press the "Disable" button. It is also recommended to go to the Security app -> Settings (cog) -> Get recommendations and turn this item off.

Also, be sure to check the settings of the apps themselves. Music, Themes, and Explorer often have separate "Receive References" switches, which will significantly clean up the Xiaomi Redmi 8 interface.

Using ADB for Advanced Management

For those who are not afraid of the command line, there is a more effective method: with the help of the ADB tool (Android Debug Bridge), you can force the packet to be disabled or removed for the current user. This does not require root rights, but requires connecting the smartphone to the computer.

First, you need to activate the developer mode. Go to Settings -> About the phone and 7 times quickly click on the build number (MIUI After you have entered the words "You became a developer", go to Additional -> For developers and enable debugging by USB.

adb shell pm disable-user --user 0 com.miui.misys


adb shell pm disable-user --user 0 com.miui.miadvice

These commands disable system services related to advertising and advice. If you decide to return everything as it was, use the pm enable command instead of pm disable-user. Be careful: disabling critical system packages can lead to unstable MIUI operation.

⚠️ Attention: When in use ADB Make sure you enter the exact name of the packet. An error in one letter can cause the system component that loads the interface to be disabled.

There are also graphical shells for ADB, such as Xiaomi ADB/Fastboot Tools, which allow you to disable ads by simply clicking checkboxes on the program interface on your PC. This simplifies the process for inexperienced users.

Alternative methods of blocking through DNS

Another effective way to combat MSA is to block ad servers at the DNS level. This is a method that does not require installing additional software on the phone itself, if you use the “Private DNS” feature in Android 9 and higher (which is relevant for Redmi 8).

In the network settings, find Private DNS (usually under Connections or Other Networks) and select DNS Host Name and type in the address: dns.adguard.com. Save settings. All requests to known advertising domain names will be blocked.

• 🛡️ Blocks ads in the browser and some applications.
• 🚫 Prevents telemetry from being sent to analytics servers.
• ⚡ It does not consume battery because it works at the network level.
• 🔄 No installation required APK-third-party file.

However, this method is not always effective against Xiaomi system advertising, as the domain names of ad servers often change. DNS-Filtering with disabling msa service in settings gives the best result.
