Smartphone Xiaomi Mi 9T He is deservedly considered one of the best representatives of the middle segent due to his frameless AMOLED-But owners often face an annoying factor, intrusive advertising that appears in system applications, in the browser and even on the lock screen, which has become a kind of payment for the affordable price of the device, but the situation can and should be corrected.
In this article, we will take a look at all the ways you can get rid of all the marketing noise that you can get from the interface, so you don't need root rights or complex code manipulation, you just need to go through the system settings in a sequential manner. You can remove banner ads on the Mi 9T, if you know where the switches are hiding.
Now, the MIUI system that the smartphone shell is based on is deeply integrated with the company's services, so there's no simple "turn off all ads" switch. The MSA (MIUI System Ads) advertising identifier is a system process that can't just be removed without losing functionality, but can be defused. We'll look at a comprehensive approach that will affect all aspects of the device.
⚠️ Note: Before making changes to your system settings, make sure you have a stable internet connection, as some services require online verification before you turn off.
Disconnecting the MSA service - the foundation of cleanliness
The first and most important step is to deactivate the MSA service, which is responsible for collecting user data and targeting advertising throughout the system. Without disabling this module, any other action will only have a temporary effect.
To start, go to the settings menu and find the password and security section, and you'll need to find the authorization and privacy section in the settings list, and you'll see a long list of services to find msa, and you'll need to put the slider next to it inactive, and it'll alert you to the consequences, but it's safe for the Xiaomi Mi 9T.
When you turn off the slider, you'll see a 10 second countdown timer. After the time you press the Disconnect button. If you press it too quickly, the system may not register the action. In rare cases, the button may be inactive or a pop-up prompting you to leave the service will appear, in which case the procedure must be repeated.
☑️ Shutdown checklist MSA
It is important to note that the MSA service can automatically turn on again after a while, if you do not follow the additional steps to clean the ad cache, so immediately after turning off, it is recommended to restart the device, this will consolidate the changes and stop background processes that may have remained in RAM.
Configuring MIUI system applications
Even after the main advertising service is disabled, the built-in MIUI apps can continue to show recommendations and banners, each with its own privacy settings that need to be checked separately.
Let's start with the Security app, which is the control center of the system. Go to it, click on the settings gear in the top right corner, and find Receive recommendations. This switch should be turned off. It's the one that's responsible for pop-ups with suggestions to clear memory or speed up the phone, which often contain advertising links.
Then we go to the standard file manager. Open the Explorer app, click on the menu (three bars) and select Settings. In the About section or in the basic settings, you also need to find and disable the Recommendations option, which will remove banners that appear when you open folders or file categories.
- 📁 Topics: Open the Topics app, go to Profile → Settings and disable "Show Ads" and "Personal Recommendations".
- 🎵 Music: In the Music app, go to Settings → Advanced settings and remove the tick from the item "Show advertisements".
- 🌐 Browser: In the standard Mi Browser browser, you need to go to Settings → Privacy and security and disable personalized recommendations.
⚠️ Note: Application interface may vary slightly depending on the firmware version (Global, EU China, but the names of key functions are usually retained.
Don't forget to check the Downloads app too. Often users don't know that this is where the ad notifications are piling up. Open the app, click three dots in the corner, select Settings, and uncheck the Show Recommended Content box, which will prevent pop-ups about viral files or new games.
Cleaning the lock screen and desktop
Ads on the lock screen Xiaomi Mi 9T often appear because of the function "Wallpaper Carousel" This feature is designed to change the images on the locked screen, but in fact is a channel for the delivery of advertising content, to get rid of this, you need to disable the corresponding service.
Go to Settings → Lock screen. Find Wallpaper Carusole (or Glance). Inside this menu, turn off the wallpaper carousel switch, and then the system will return to the static image you choose and stop downloading the ad units.
What if the carousel doesn't shut down?
You should also look at the widgets on your desktop. Some of them, especially the Widget Tape (swipe left), may contain a news stream with inlays. To turn this off, pinch your two fingers on your desktop, click Settings and select More, where you can turn off the Widget Tape or select a news source (e.g., Yandex or turn it off completely).
For full effect, it is also recommended to disable the personalization of ads in your Mi Account. Go to Settings → Mi Account → Mi Cloud → Advertising. Here you need to deactivate Personalized Advertising. This action will tell Xiaomi servers that you do not want to receive targeted offers based on your interests.
Working with notifications and browser
Often, the ads don't come from the system itself, but through notifications from sites you accidentally subscribed to in your browser, which is especially true for the standard Mi Browser or Chrome browser, and checking site permissions is a critical step.
In your browser, go to your settings and find Notifications or Site Settings, which will list all the resources that are authorized to send you push notifications, carefully review the list and delete any suspicious sites, especially those whose names do not tell you anything, usually news aggregators or sites with free content.
| source of advertising | Where to turn off | Action. |
|---|---|---|
| Systemic advertising | Settings → Passwords and security | Disable msa |
| Lock screen | Settings → Lock screen | Turn off the wallpaper carousel |
| MIUI applications | Settings within each application | Remove the "Recommendations" box |
| Site notifications | Browser → Settings → Notifications | Delete suspicious websites |
If you use third-party launchers or memory cleaner apps, check their settings. Often they are the source of pop-ups on top of other applications. Xiaomi Mi 9T is better to rely on built-in optimization tools that we have already set up.
Using DNS to Block Advertising
For those who want to go further and block ads not only in the system, but also in games and third-party applications, there is a method of changing the system. DNS-It doesn't require any additional software and it works at the network connection level.
Go to Settings. → Connection and Sharing (or "Other Connection Ways"). Find Private DNS-Select the option Host Name of the provider DNS And enter the address:
dns.adguard.comThis method is particularly effective for blocking trackers in free apps. However, it is worth remembering that in rare cases, using a third-party DNS can slightly increase ping in online games or slow down the opening of some sites. If you notice problems with Internet speed, just return the setting to the Auto position.
💡
Use Do Not Disturb at night to prevent advertisements from unscrupulous apps from waking you up if you miss some source of spam.
Frequent problems and their solution
While cleaning the Xiaomi Mi 9T, users may encounter some difficulties. MIUI is constantly updated, and the location of some points may change, or the MSA service may resist shutdown. Consider typical scenarios.
If the MSA disable button is inactive (gray), check the Internet connection. To confirm the action, the system needs to contact the server. Also try to switch the system language to English, disable the service, and then return Russian.
Another problem is that ads appear after a firmware update. When a major MIUI update is made, privacy settings can be reset to factory ones. Therefore, after each major update (for example, switching from MIUI 12 to 13), it is recommended to recheck the status of the msa service and setting recommendations in applications.
⚠️ Warning: Do not install low-rated “Antivirus” or “Cleaner” apps from the Play Market – they are often themselves a source of ads and viruses that are harder to remove than system banners.
If the ad continues to appear as full-screen windows at random, it is likely the newly installed app is to blame. Go to Settings → Apps → All Apps and look carefully at the list. Look for apps without an icon or with a suspicious name that have been installed recently and remove them.
