When buying the affordable Xiaomi Redmi 9T smartphone, many users are faced with intrusive advertising that appears in system applications. This is a fee for the low cost of the device, but the situation can be fixed. Modern MIUI shells allow you to flexibly adjust privacy and limit data collection, which automatically reduces the amount of advertising content.
The process of cleaning the interface does not require root rights or firmware reflashing. All the necessary tools are already built into the Android operating system with the MIUI shell. You only need to follow the steps carefully to deactivate the services responsible for displaying banners and recommendation articles.
In this article, we’ll look at all the locking techniques, from disabling the MSA system service to fine-tuning each embedded application, and turning your Redmi 9T into a clean tool for work and entertainment without unnecessary visual noise.
Disabling the MSA system service
Xiaomi’s main source of advertising on smartphones is the MIUI System Ads app (often referred to as msa), which collects data about your actions and generates personalized advertising offers, and without disabling this service, other settings may not be effective.
To start, you need to go to the authorization and permissions menu. Open Settings, then search for passwords and security. In the list, select Access to Personal Data. This list shows the list of apps that have the right to collect user information.
Find the msa string in the list and put the switch into an inactive state. The system will warn you that the shutdown may affect the operation of certain functions. Press Disable and wait 10 seconds, then confirm the action with the Disable button (10).
- 🚫 The service will stop collecting analytics about your activities in the system.
- 🛑 Disappeared banner ads in standard utilities.
- ⚙️ Reduced load on the processor and RAM.
- 📉 Traffic consumption in the background is reduced.
What to do if the button is inactive?
It's important to understand that you can't always turn off msa the first time. System algorithms can resist changing settings. If you fail, just repeat the procedure after 24 hours. Usually, on the second or third attempt, the restriction takes effect.
Setting up the "Security" application
The built-in antivirus and the Security optimizer are another channel for broadcasting advertising content, and by default, the recommendations that appear when you run a check or clear memory are included here, and to remove them, you need to change the internal settings of the application itself.
Run the Safety app on the home screen. Click on the gear icon in the top right to enter the settings menu. Find the Receive recommendations section and disable this setting. This action will remove the news feed and promotional material from the utility interface.
☑️ Checking security settings
Also worth paying attention to is the Cleanup section, which may contain additional switches that are responsible for displaying ads after the scan is completed, and make sure that all sliders associated with “recommendations” are turned off.
⚠️ Note: Do not remove the Security app by force ADB, It's a system component that's essential for the permissions and power management of Redmi. 9T.
After making the changes, restart the device, so that the cached data of the ad modules is completely cleared from the RAM, you will notice that the interface has become cleaner, and unnecessary banners no longer appear.
Cleaning the desktop and the application “Conductor”
The standard MIUI launcher and file manager also have built-in monetization mechanisms. In the Explorer app, ads often appear as banners at the bottom of the screen or in the popular files section, and you can remove them through the settings menu.
Open Explorer, click on the menu (three bars) and select Settings. Find About and click on it several times until the debugging menu appears (in some versions). In newer versions of MIUI, just find the Recommendation switch or Receive news and deactivate it.
The Redmi 9T desktop can also offer a Google News Feed or Yandex to the left of the first screen. To turn this off, swipe right on your desktop, tap on the gear, and select the Widget Ribbon → No. This will speed up the interface.
- 📂 Banners will disappear at the bottom of the Explorer.
- 🏠 The news feed on the left of the desktop will disappear.
- 🚀 Accelerate opening of folders and files.
- 🔋 Background activity of network services will decrease.
💡
Use a third-party file manager, like Total Commander or Google Files, which is completely ad-free and faster than Xiaomi’s standard solution.
Remember that after major MIUI updates, settings may reset. Check these sections periodically to make sure that the ad modules are not activated again, which is especially true when switching between Android versions.
Disabling Advertising in System Applications
Besides the basic services, advertising integrations are present in the calculator, voice recorder, downloads and Music, each of which requires separate attention, and the process is similar everywhere: logging into the settings of a particular application and searching for a recommendation item.
In Downloads, click three dots in the corner, select Settings and turn off Show Recommendations. In Music, go to settings, find Advanced Settings, and remove the tick from Receive Recommendations.
The Calculator and Recorder have a similar procedure: Open the settings menu inside the app and look for any mention of the words "Recommendations," "News," or "Promotions." In some regions, these items may be called "Get hints."
| Annex | The path to adjustment | What to turn off |
|---|---|---|
| Downloads. | Menu → Settings | Show recommendations |
| Music. | Menu → Settings → Extended | Receive recommendations |
| Topics | Profile → Settings | Showing Advertising, Auto Update |
| browser | Menu → Settings → Notifications | Notifications, Recommendations |
The Theme app deserves special attention. It's one of the most aggressive sources of advertising. Go to profile (the person in the corner), then to Settings. Here you need to turn off all the switches: Show ads, Auto Update and Personal Recommendations.
💡
Consistent verification of each system application is the only way to ensure that the interface is completely cleaned of spam.
Resetting the advertising ID and tracking restrictions
Android uses a unique Advertising ID to target content, and Redmi 9T can reset that ID or completely limit its use, making ads less personalized and intrusive.
Go to Settings → Passwords and Security → Privacy. Go to Ad Services. Here you will see the option Reset Ad ID. Click on it. It is also recommended to activate the switch to Disable Ad Personalization.
This measure won’t eliminate ads completely, but it will make them random. For ad networks, your Redmi 9T will be a blank slate, which will reduce the frequency of annoying banners based on your search history.
- 🔄 Resetting ID breaks ties to past data.
- 🛡️ Tracking restrictions increase privacy.
- 📉 Advertisers get less information about you.
- ⚡ Advertising profile is being created (in the direction of neutrality).
In addition, in the Passwords and Security section, you should check Special Features, make sure that there are no suspicious applications that can inject ads on top of other windows, often there are miner viruses or scripts hiding there.
Using DNS to Block Advertising
One of the most effective anti-advertising techniques of today is using a private filtered DNS, which works at the network level and blocks requests to known ad servers, preventing them from uploading content to your Redmi 9T.
You don't need third-party apps. Go to Settings → Connection & Sharing → Private DNS. Select DNS Host Name Mode and type in the address: dns.adguard.com. Save settings.
dns.adguard.comOnce you have setups, all traffic that goes through the DNS will be filtered, and this will remove ads not only in the system, but also in many applications and browsers, but you should be careful: if the address is entered incorrectly, the Internet may stop working.
⚠️ Attention: When using private DNS Some applications (such as carrier or banking) may not work properly. If you notice network access issues, return the settings. DNS auto-mode».
The advantage of this method is that it's versatile, it doesn't require root rights, it doesn't load the processor with constant computing, and it works right after you turn on your phone, and it's the most efficient way to lock the phone globally without installing any additional software.
