Xiaomi smartphone owners often face intrusive ad integration that can appear in the most unexpected places of the interface.Advertising banner can pop up when unlocking a device, in the notification curtain or even on top of running applications, significantly reducing the comfort of using the gadget. Users wonder why the system allows such behavior and how exactly the MIUI mechanism works in this context.
The main reason lies in the company’s business model, which involves selling hardware at a minimal margin.To offset costs and generate profits, the company uses monetization through software services and advertising. However, unlike many competitors, the Xiaomi ecosystem provides tools to completely disable this functionality, making content management accessible to everyone.
Let’s take a closer look at where you might encounter inserts and what the system processes are behind them. Understanding the mechanics of system services will not only help you remove current banners, but also prevent them from appearing in the future, especially for new users who first purchased a device based on a MIUI or HyperOS shell.
System notifications and lock screen
One of the most annoying places to see unsolicited content is the lock screen, and often users see beautiful wallpapers with text that opens the browser or app store when clicked, and this is the Wallpaper Carousel feature, which is activated by default on many Redmi and Xiaomi models, and is positioned as a personalization service, but is actually a channel for distributing advertising materials.
In addition, banners can appear in the notification panel in the form of system messages from the application “Security” or “Downloads”. System utilities can report alleged viruses, the need to clear memory or update applications, but when you click on the link, you often are sent to a page with a proposal to buy a product or install a game.
⚠️ Warning: Some banners on the lock screen may be disguised as messages from messengers. Always check the source of the notification before clicking to avoid starting the malware installation.
To fully control the situation, you need to understand which services are responsible for displaying graphics. Below is a table of the main components of the system that generate advertising traffic:
| System component | Type of content | Wherever it manifests |
|---|---|---|
| MSA (MIUI System Ads) | Banner advertisements | Security folder, desktop |
| Wallpaper Carousel | Wallpaper carousel | Lock screen |
| GetApps | Recommendations of the annexes | Notifications, folders. |
| Cleaner | Cleaning proposals | Pop-ups |
Disabling these components requires a consistent approach, since simply ignoring them does not eliminate the very possibility of activating them after a system update.
Advertising in standard applications
The second front of the fight against intrusive content is the standard set of applications preinstalled by the manufacturer: Explorer, Music, Video, and even Calculator can contain built-in advertising modules, most often in the form of news recommendations at the bottom of the screen or pop-up windows when a program is launched.
Special attention should be paid to the application “Downloads”, which is often used as a gateway to promote games and utilities from affiliate networks. When you open a file or complete the download, a full-screen banner may appear. MIUI allows you to flexibly adjust these parameters, hiding unnecessary interface elements.
- 📱 In the Security app, the advertisement appears in the Cleanup and Antivirus section».
- 🎵 In Music and Video, banners are often integrated into the recommendation tape.
- 📂 In the “Conductor” advertising blocks can be located on the start page.
To eliminate the discomfort, you have to go to the settings of each particular application, and you usually just have to find the "Receive recommendations" or "Show ads" switch and deactivate it, and this action does not disrupt the functionality of the program, but only removes commercial inserts.
💡
Before disabling ads in system applications, make sure you have a stable internet connection, as some settings only apply after synchronization with the Xiaomi server.
Personalization settings and recommendations
Deep inside the operating system, the section responsible for collecting user data for targeted advertising is hidden. Personalized recommendations analyze your smartphone usage habits, search history, and frequently opened apps to show more relevant, yet still promotional offers.
To disable this feature, you need to go to the settings of your Xiaomi account. The path usually looks like: Settings → Passwords and security → Access to personal data. There is a switch that allows or prohibits the system from using your data to improve the user experience, which in practice means setting up advertising results.
It's also worth checking the user experience section, which collects statistics about how the device works, and although this is not direct advertising, disabling this option reduces the amount of information transmitted to the company's servers, which indirectly affects the frequency and accuracy of advertising campaigns targeting.
How to find hidden advertising settings?
Therefore, after each flashing or reset, it is necessary to re-go through the procedure of disabling advertising services.
Pop-up advertising in the browser and applications
If banners appear randomly on top of any apps, including those that shouldn’t be advertised (calendar, watch, telephony), then the problem is most likely not in Xiaomi’s system, but in malware or browser settings. Pop-ups are often a sign of an ad virus or aggressive expansion.
Check the installed applications. Often users install programs for "battery saving", "speeding up the Internet" or "flashlights" that require suspicious permissions. These tools can generate advertising traffic on top of all windows. Deleting suspicious software is the first step to solving the problem.
☑️ Checking for advertising viruses
The second source of the problem is notifications from websites in the browser, and if you accidentally allow a site to send notifications, it can spam you with banners even when the browser is closed. To fix this, go to the browser settings (Chrome, Mi Browser) and find the section "Notifications" or "Sites" where you can revoke permissions.
Third-party applications and widgets
Don’t forget that the source of banners can be third-party widgets installed on the desktop. Weather widgets, news widgets or “cleaners” from unknown developers often work on the principle of displaying ads in exchange for free functionality. Android allows applications to display content on the desktop, and this is actively used by advertisers.
It's recommended that you do a desktop revision, and if you see a widget that you didn't consciously install, or a widget from a developer you don't trust, delete it, and also check the list of widgets in the add-on menu, which often hides the sources of the problems.
- 🗑️ Remove widgets from unknown developers.
- 🔍 Check the permissions for each widget on the desktop.
- 🚫 Avoid installing “accelerators” and “antiviruses” from unreliable sources.
Often, these applications are disguised as system apps using similar icons and names. Read the developer name carefully before installing or leaving the application on the device.
Global Advertising Services Disconnection (MSA)
The most radical and effective method of combating this is to disable the MSA system service (MIUI System Ads), which is responsible for loading and displaying most banner ads in the interface, and without it, advertising will cease to be physically loaded.
To do this, go to Settings → Passwords and Security → Access to personal data. Find the “msa” list and turn off the switch. The system will warn you that this may affect the operation of certain functions, and ask you to wait 10 seconds before confirming.
⚠️ Attention: When disconnected MSA The system may try to dissuade you several times or show you a network error. That's OK. Repeat the shutdown attempt until it's successful. Sometimes you need to turn off the Internet on your phone before this procedure.
If you can't turn it off the first time, try flying, and you should also turn off similar access for Mi Video, Mi Music and GetApps if you don't use them actively, which will completely clean up the system from advertising noise.
What if the MSA is activated by itself?
After a successful shutdown, it is recommended to restart the device, which will consolidate the changes and clear the cache of the ad modules, you will notice that the interface has become more responsive and the unnecessary banners have disappeared.
💡
Disabling MSA is a key step that eliminates 90% of all system advertising in the shell of MIUI and HyperOS.
