Smartphone owners Xiaomi, Redmi i POCO often notice the mysterious MSA abbreviation in the list of running processes. When you try to find out more or complete the process, the system issues warnings about the critical importance of the component. This causes concern among users who fear for the security of personal data or battery consumption.
In fact, MSA is MIUI System Adsa system component responsible for displaying advertising banners in standard shell applications. Although it is deeply integrated into the operating system, its activities can be limited or stopped completely without losing the warranty and functionality of the device.
In this material we will take a detailed look at why this process is needed, why it consumes resources and how you can safely disable intrusive advertising. You will learn to distinguish between system errors and the normal operation of the advertising module.
Deciphering the abbreviation and the purpose of the process
The abbreviation MSA literally translates as MIUI System Ads. This is not a virus or third-party malware, but a legal component of the operating system Android with shell MIUI or HyperOS. The main task of this service is the delivery and display of targeted advertising in system applications such as Explorer, Music, Security and the lock menu.
Developers use this mechanism to subsidize the cost of smartphones. It is thanks to the presence of advertising modules that brand devices are often cheaper than their “clean” counterparts. The process runs in the background, periodically requesting location and app usage data to build an advertising profile. Android. The process runs in the background, periodically requesting location and app usage data to build an advertising profile.
It is important to understand that MSA is only an execution mechanism. It receives commands from servers and displays content. The file itself does not collect data, but is part of an analytics collection ecosystem. Disabling this component will not break the phone, but may cause temporary errors in the operation of some system widgets.
⚠️ Attention: An attempt to forcefully delete a file through root access or system modifiers may lead to a cyclic reboot of the device (bootloop). Use only standard methods of disabling through settings.
There is a misconception that MSA is only responsible for banners. In fact, this service can also initiate push notifications with offers to install games or applications from the store. everything is a long time ago GetApps.
The impact of MSA on performance and autonomy
Many users wonder why the battery drains even when the phone is idle. Often the cause is the active activity of background processes, including MSA. Although the process itself does not require the power to render complex graphics, constantly polling servers and downloading content consumes traffic and energy.
The impact is especially noticeable on older smartphone models with a small amount of RAM. When RAM full, the system begins to use virtual memory more actively, and background processes such as advertising modules interfere with the effective caching of frequently used applications. This leads to micro-freezes of the interface.
- 📉 Traffic consumption: The process constantly updates advertising databases, which can quietly “eat up” megabytes of mobile data.
- 🔋 Battery low: Activity in the background prevents the processor from going into deep sleep mode, increasing the percentage of discharge in standby mode.
- 🐌 Slowdown: When opening system folders (for example, “Downloads”), there may be a delay before the ad block is displayed.
It is worth noting that in new versions HyperOS advertising algorithms have been changed optimized. Now the load on the processor is distributed more evenly, but it is impossible to completely eliminate the impact on autonomy without disabling the service.
If you notice that your smartphone is heating up in your pocket, check the battery usage statistics. If MIUI System Ads or msa is in the top 5 energy consumers, this is a signal to action.
Periodicly clearing the Security application cache helps clear accumulated ad module errors and can temporarily reduce the load on the processor.
Is it possible to completely remove MSA from device
Since MSA is a system application, standard means Android cannot be removed. The "Delete" button in the application menu is grayed out or missing. This is done to protect the integrity of the shell: the developers assume that the user may want to return the advertising functionality, and leave this option.
There are ways to completely remove it via ADB (Android Debug Bridge) from the computer or obtaining root access. However, such actions carry risks. When updating the firmware over the air, the deleted system file can be restored automatically, or, conversely, its absence will cause version conflicts and errors.
The safest method recommended by experts is not deletion, but disable. This breaks the connection between the application and the server, stopping processes, but maintaining the integrity of the file system. If necessary, the component can be activated back in one click.
⚠️ Attention: The settings interface may differ depending on the version of MIUI (12, 13, 14) or HyperOS. The location of menu items can be changed by developers.
Users using custom firmware (for example, Xiaomi.eu) often do not encounter this problem, since in such assemblies advertising modules are cut out at the firmware source code level.
Instructions: how to disable advertising in MIUI settings
The easiest way to neutralize msa is to use the built-in privacy tools. This method does not require a connection to a computer and is safe for any user. It effectively blocks personalization and display of most banners.
First you need to go to the settings menu. The path may be slightly different, but the logic remains the same for all current versions of the shell. You will need to find the section responsible for passwords and security.
The sequence of actions is as follows:
- Open
Settingsyour smartphone. - Go to the section
Passwords and security(orAdditional). - Select item
Access to personal data(Authorization & revocation). - Find in the list msa and disable slider.
- The system will start a countdown timer (usually 10 seconds). Click
Disable.
After this, the system may try several times to convince you to leave the service enabled, reporting network errors or unstable operation. Ignore these messages and continue to insist on disabling.
☑️ Checking MSA disabling
If with It was not possible to disable it the first time, repeat the procedure 2-3 times. Sometimes servers Xiaomi are under load and cannot immediately process a request to revoke permissions.
Disabling the personalization of advertising recommendations
Even after revoking permissions from a process MSA, tails may remain in the system in the form of personalized recommendations. They are managed by a separate service - MIUI Daemon or simply a recommendation module. To (drastically) resolve the issue, you need to disable it too.
Return to the menu Passwords and security → Privacy. Here find the item Advertising services (Ad services). Inside, you need to disable the option Advertising personalization. This will prevent the system from using your data about search queries and visited sites to select banners.
It is also worth checking the settings of individual system applications. For example, in the “Music” or “Themes” application, there is often a separate “Get recommendations” toggle switch in the profile settings. It should also be deactivated.
- 🔍 Search engine: In global search (swipe down on the desktop), go to settings and disable “Popular.”
- 📂 Explorer: In Explorer settings, uncheck the “Receive recommendations.”
- 🔒 Lock screen: In the "Wallpaper Carousel" theme, disable receiving updates if advertising appears there.
An integrated approach allows you to remove up to 95% of all advertising noise, turning the interface into a clean and productive tool.
What to do if the msa item has disappeared from the list?
Sometimes after a firmware update, the name of the process may change or it may be hidden. Try searching for “MIUI System Service” or “System Services” in the list of applications. You can also use the search by settings by typing in “advertising” or “ads”.
Table: Comparison of methods to combat advertising
There are several approaches to solving the problem of intrusive banners. The method you choose depends on your technical background and willingness to risk system stability. Below is a comparison of the main methods.
| Method | Complexity | Efficiency | Risks |
|---|---|---|---|
| Disablement in “Data Access” | Low | High | Minimum |
| Disable personalization | Low | Medium | None |
| Use of DNS (Private DNS) | Medium | High (blocks traffic) | Some applications may not work |
| Removal via ADB (Root) | High | Maximum | Possible loss of warranty, risk of “brick” |
For most users, the optimal choice is a combination of the first two methods. They do not require special knowledge and are easily reversible. The use of DNS filters (for example, dns.adguard.com) is an excellent addition, as it blocks advertising at the network level in all applications, not just system ones.
Radical measures like deleting system files are justified only for experienced enthusiasts who understand the structure. Android. Under normal circumstances, this is not necessary.
The combination of disabling MSA in permissions and setting up Private DNS gives the best result without the need for root access.
Frequently asked questions (FAQ)
Is it safe to disable MSA? Will the phone break?
Yes, it's safe. MSA is an advertising delivery service, not a critical system component such as a phone book or communications module. After disabling it, the phone will continue to work normally, it will simply stop showing banners in the system interfaces.
Why does MSA appear in the list of processes again after disabling it?
The shell MIUI periodically checks the status of system components. If you see a process, but there are no advertisements, it means it is inactive. If advertising resumes, try revoking permission again in the “Access to personal data” menu.
Does turning off advertising affect the speed of your smartphone?
Yes, there is a positive effect. RAM is freed up, the processor is less loaded with background tasks, and Internet traffic is saved. On budget models, this can give a noticeable increase in performance.
Is it possible to remove MSA on the global version of the firmware?
You cannot remove (uninstall) without root access, but you can completely disable it through the settings, as described in the instructions above. Global firmware versions also contain this module, since it is part of the brand’s ecosystem.
