Budget smartphone owners often face intrusive banner ads that appear in the most unexpected places on the interface. For owners of the Redmi 9T, this problem is especially relevant, since the affordable price of the device is often offset by aggressive monetization by the manufacturer. However, there is a proven algorithm of actions that allows you to reduce the amount of advertising content to an absolute minimum or remove it completely.
In this article, we will take a closer look at all the hidden MIUI settings that are responsible for targeted offers and system notifications. You won’t need superuser rights or third-party software installations, as all the necessary tools are already built into your smartphone’s operating system.
MSA Disconnection: The Main Source of Advertising
The main driver of advertising activity in the MIUI shell is a system process called MSA (MIUI System Ads), which collects data about your actions and translates banners into standard applications, and to deactivate it, you need to log into the authorization menu and withdraw consent to the service.
Go to Settings → Passwords and Security → Access to Personal Data. In the list that opens, find msa and switch the slider to an inactive state. The system will require you to wait 10 seconds, then prompt you to revoke access. Press the appropriate button. If the first error occurs, repeat the procedure 3-4 times until you see a message about a successful shutdown.
☑️ Checking the shutdown MSA
It is worth noting that MSA is closely integrated with other services of the company, so its disabling may temporarily affect the operation of some system widgets. However, for basic smartphone functionality, such as calls or messages, this action is safe.
Advertising personalization setting
Even after the MSA service is disabled, the settings that collect data for targeting remain in the system. The advertising ID allows Xiaomi algorithms to build your digital profile and offer relevant products. To break this link, you need to manually clear your personalization settings.
Open Settings → Passwords & Security → Privacy → Advertising Services. You must deactivate the Ad Personalization option. Immediately after that, click Reset Advertising ID. This action generates new random code that is not related to your previous device usage history.
It's important to understand that resetting your ID doesn't remove ads completely, but it makes them less intrusive and more random. Algorithms lose understanding of your preferences, so instead of targeted banners, you'll see generic content, which greatly reduces the likelihood of random purchases and clicks on fraudulent links.
Managing Notifications in System Applications
Special attention should be paid to the built-in applications, which are often the source of pop-ups. Browser, memory cleanup, music and themes all have their own recommendations settings. To remove ads on Redmi 9T, you need to go through each of them.
Start with the "Security" app. Open it, click on the gear in the top right corner, and find "Receive recommendations." Turn off this switch. Similar steps should be taken in the "Music," "Themes" and "Downloads" apps, and in each of them, you should find the settings menu and remove the boxes that contain the words "recommendations," "news" or "notifications."
⚠️ Note: In Downloads, settings may be hidden in a menu called at three points" → "Show recommended content and disable it.
Don't forget the Mi Browser browser, which is set to show news feeds and promotional materials by default. Go to its settings, select Home Page and disable the display of news cards. It will also be useful to disable push notifications from the browser itself in the system settings of Android notifications.
Disabling advertising in the "Themes" application
Themes is one of the most active sources of advertising traffic, and banners can appear when you unlock the screen, if you have a wallpaper carousel theme installed, or just when you open the store, and you need to turn off several parameters inside the app for complete comfort.
Launch the Themes app, go to the profile (human icon) and click on the settings button. Find the Advanced Settings section and turn off the Receive References feature. Then go back to the main screen of the theme store and make sure that the Autoplay Video option is disabled. This will not only remove ads, but also save traffic.
Separately, check the wallpaper carousel settings. If you use this feature, go to Settings → Wallpaper → Wallpaper carousel. In the settings, find Get References and turn off this option, which will prevent advertising slides from appearing on the lock screen.

There are several approaches to combating intrusive content: system settings, use of the system. DNS-Each method has its own advantages and disadvantages that Redmi is owners should consider. 9T.
System settings are the safest, but not always the most effective method, and they don't require additional software, but some types of advertising may remain. DNS-Filtering (for example, through AdGuard) DNS) It blocks requests at the network level, which is effective for most applications, but can slow the Internet down.
| Method | Efficiency | Difficulty | Impact on the system |
|---|---|---|---|

| Private DNS | Medium | Low. | Possible slowdown. |
| Blocking applications | Very high. | Medium | Battery consumption |
For most users, the best solution is to combine disabling MSA and customizing personalization, enough to make smartphone use comfortable without installing third-party software. More complex methods should be used only if standard tools do not give the desired result.
Using Private DNS to block
Modern versions of Android installed on Redmi 9T, Use the Private Function DNS (Private DNS). This method redirects all domain name requests through a server that automatically filters ad trackers.
To activate, go to Settings → Connection and Sharing → Private DNS. Select Host Name of DNS Provider and enter the address: dns.adguard.com. Save settings. After that, all requests to known ad servers will be blocked at the connection level.
