What is MSA on Xiaomi Redmi: The Complete Guide

Owners of Xiaomi Redmi and Poco smartphones often encounter a mysterious process called MSA in Task Manager or Security app, which raises questions, especially if it consumes a noticeable amount of power or traffic, and many users mistakenly believe that it is a virus or malware that needs to be removed immediately.

It's not really that critical, but it requires an understanding of how MIUI works. MSA (MIUI System Ads) is the system component that displays ads in standard applications in the company. It's built deep into the operating system and is not a third-party program. Understanding its features will help you control your gadget's behavior.

In this article, we'll go into detail about why this process is needed, whether it's worth turning it off, and how to do it safely. We'll look at the various methods available to the average user without having to get super-user rights, and your goal is to optimize the operation of the device while maintaining its stability.

The essence of the MSA process and its function

MSA stands for MIUI System Ads. It's an embedded shell mechanism designed to monetize budget devices. Xiaomi is known for selling smartphones at a minimal margin, offsetting costs through software services and advertising. It's for displaying banner ads in Explorer, Music, Themes and installing apps that this component is responsible for.

The process is not limited to visual advertising, it also collects statistics on device usage to personalize offers, system analytics helps companies understand which features are popular and which need to be refined, but for the end user, this often results in increased battery and traffic consumption.

It is important to note that MSA is not a virus, and antivirus scanners do not label it as a threat, as it is a legitimate part of the firmware, and removing or disabling this component will not disrupt basic phone functions such as calls or messages, but can change the behavior of some system applications.

• 📢 Responsible for displaying advertisements in system interfaces.
• 📊 Collects anonymous statistics on smartphone usage.
• 🔄 Updates advertising modules in the background.
• ⚙️ Integrated into the work of the applications “Security” and “Downloads».

Users often notice MSA activity right after a major firmware update, because upgraded components can re-request permissions or activate services by default, and control this process allows you to significantly extend battery life.

Effects of MSA on performance and battery

Many Xiaomi Redmi owners wonder why the phone is running out even when it's lying idle. Often the culprit is background activity from system services, including MSA. The process periodically wakes up to download new advertising content, which requires an Internet connection and a processor.

While the power consumption of a single start may be minimal, the cumulative effect per day is noticeable, background activity prevents the device from going into deep sleep, especially for models with less than the most capacious batteries or for users who are out of charge access for a long time.

⚠️ Attention: Disconnection MSA does not guarantee the complete disappearance of all advertising. Some banners may be cached by other system services or third-party applications installed by you yourself.

Also, persistent network queries can slightly increase mobile traffic consumption, and if you have a limited Internet bundle, it can come as a nasty surprise, and optimizing background processes is a key step to improving overall interface responsiveness.

It’s also worth considering that the impact of this component may differ on different versions of MIUI and HyperOS, and in new versions of the shell, the company is implementing more aggressive energy saving algorithms that may limit the operation of the MSA, but you should not rely on this completely.

Methods to disable MSA through settings

The safest and easiest way to restrict MSA activity is to use built-in privacy settings, you don't need any special programs or a computer, just look at the ad service settings menu carefully, and this method works on most current firmware versions.

You have to go to the settings menu first, and the path may vary slightly depending on the shell version, but the logic remains the same. You have to find the security and privacy section, and there are the main switches that control data collection.

Find Password and Security, then go to Privacy. From the list of services, find msa or MIUI System Ads. Translate the switch to "Off." The system will ask you to wait 10 seconds before confirming an action, which is standard protection against accidental pressing.

Once you turn off the main module, you should also turn off recommendations, and in the same menu, find Receive recommendations and deactivate it, which will remove intrusive tips on installing applications and using services.

• 🔒 Go to Settings. → Password and security → Confidentiality.
• 📉 Find the msa service in the list and turn it off.
• 🚫 Turn off the option “Receive recommendations».
• 🗑️ Clear the data of the Security app to reset the cache.

If the switch returns to its original position or the system writes an error, try repeating the procedure several times. Sometimes it takes 3-4 attempts for the server to receive a command to shut down. This is a known feature of the shell.

Restricting work through the Application Manager

If the standard shutdown didn't work, or you want to amplify the effect, you can use a more radical method, which is to restrict the rights of the application. MSA physically, but it will prevent it from starting and using the Internet. MIUI.

Go to the Apps menu and select All Apps. In the upper right corner, click on three dots and select Show System. Find msa. Go inside and select Other Permits. You must deny network access (Wi-Fi and mobile Internet).

Next, find AutoStart and make sure it's turned off. Also, from the Battery menu (or "Saving Charge"), select No Limits mode (so the system doesn't wake it up) or, conversely, a hard limit if such an option is available in your version of Android. The logic may differ: sometimes you need to disable background activity.

Once you have set the restrictions, force the process to stop. Press the Stop button at the bottom of the app information screen. This action will reset the current MSA session.

💡

If the Stop button is inactive, first turn off network access, then try again. Sometimes you need to reboot after you change the access permissions.

Removal via ADB (for advanced users)

For those who are not afraid of a computer and want to get rid of system debris, there is a method of debugging via USB. Using the ADB tool (Android Debug Bridge) allows you to remove system packages without root rights. This is the most effective method, but it requires caution.

First, you need to activate the developer mode. Go to About Phone and quickly press 7 times on the MIUI Version. Then in advanced settings, turn on Debugging over USB. Connect your smartphone to your PC with a cable.

adb shell pm uninstall -k --user 0 com.miui.misys


adb shell pm uninstall -k --user 0 com.miui.systemAdSolution

Executing these commands will remove the packages responsible for system advertising and analytics. Deleting the com.miui.systemAdSolution package is a key step to completely eliminate MSA. However, remember that when reset to factory settings, all applications removed in this way will return.

⚠️ Note: Be extremely careful when typing commands ADB. Removing mission-critical system components (non-advertising) can cause a device to bootloop.

For convenience, you can use graphical shells for ADB, such as Xiaomi ADB/Fastboot Tools or Universal Android Debloater.They have ready-made lists of safe to remove applications, where the MSA is usually marked as recommended for removal.

Possible problems and solutions

In the process of combating advertising, users may face a number of difficulties, such as when you update the firmware, all settings can be reset. This is normal behavior: updating the system often returns standard privacy values, you will have to repeat the procedure of disabling manually.

Another problem is that some applications are getting bugged, and if you delete MSAs through ADB, the Themes or Music app may not work properly or close when you start, and you may have to restore deleted packets through the install command.

It is also worth mentioning the third-party DNS-services. Use of services. DNS Advertising filtering (e.g. AdGuard) DNS) can block requests MSA At the network level, even if the process is active, it's a good barrier.

• 🔄 When you update the firmware, the settings are reset – check them again.
• ❌ Removal through ADB It can disrupt the standard applications.
• 🌐 DNS-Filtering is an effective way to block without removing.
• 📱 Different Redmi models may have different item names.

If you notice strange behavior after manipulation, try resetting the network or, in extreme cases, a complete data reset, but before you do, make sure that the problem is changing the system settings.

💡

Complete removal of MSA is possible only through ADB, but for most users, a full-time disabling in the privacy settings is enough.
