The Redmi Note 9 series is well-deservedly popular for its excellent price-performance ratio. However, owners are often annoyed by the intrusive advertising that appears in system applications and the MIUI interface. It is not a virus, but a built-in marketing strategy of the manufacturer, which allows you to reduce the cost of devices.
Fortunately, most ad units can be easily deactivated manually without obtaining root rights. You don't need to be a programming expert to clear the interface of unnecessary visual noise. In this article, we'll take a look at all the steps to clean the system completely.
The shutdown process takes only 10-15 minutes, but it requires care, because the settings are scattered across different menus, and system advertising affects the speed and battery consumption, so removing it is not only a matter of comfort, but also of optimizing the device.
MSA Disconnection: The Main Source of Advertising
The main generator of advertising content in the MIUI shell is the MSA (MIUI System Ads) system application, which analyzes your actions and loads banners into standard utilities, and to stop this process, you need to find the service in the application list and turn it off.
Go to your smartphone settings, select Apps and click All Apps. Search MSA (may be called System Advertising or have an Android logo) in the list. Click on the name, then select Disable. The system will alert you to the risks, but for the average user, disabling is safe.
⚠️ Warning: the "Disable" button may not be activated until 10 seconds after the warning appears.
After a successful shutdown, ads in most places will disappear instantly, however, some system applications can cache ad modules, so it is recommended to immediately restart the device to apply the changes.
☑️ Checking the shutdown MSA
Configure privacy and advertising ID
Even after the main service is disabled, the system still has an ad personalization mechanism based on your unique identifier. ID It allows algorithms to collect data about your preferences, and it is recommended to reset or disable this feature to improve privacy.
To do this, open Settings, scroll down to Password and Security. Find Privacy and select Advertising Services (or Advertising) and switch the Ad Personalization slider to an inactive state.
The menu also has a button called Reset Ad ID, which confuses targeting algorithms regularly, making the offers less relevant and therefore less intrusive, an important step for those who value their digital data.
💡
Reset your advertising ID once a month if you cannot completely disable personalization due to regional firmware restrictions.
Removing Advertising in Standard Apps
After global tweaks, you should go through individual system utilities that often have their own recommendation switches. In Redmi Note 9, such settings are found in Explorer, Music, Themes and Security.
In the Security app, click on the settings gear in the top right corner. Find the "Receive recommendations" option and turn it off. You should repeat the same steps in Explorer: click the menu (three bars), select Settings, and turn off Recommendations.
- 📱 Topics: Go to profile (the person below) → Settings → Hide the adverts.
- 🎵 Music: menu → Settings → Advanced settings → Show an advert.
- 📂 Downloads: three points → Settings → Show recommended files.
Keep in mind that the interface may vary slightly depending on the version of MIUI. If you haven't found a clause, look for a similar one, as translations sometimes change from update to update.
What happens if the switch comes back?
Disabling notifications from system services
Often, it’s not the in-app banners that annoy you, but the pop-up notifications in the curtain, which can come from MIUI Daemon, Getting Popular Apps, or Usage Statistics, which are components that constantly monitor activity for analytics.
To prevent them from sending notifications, go to Settings → Notifications and Status Bar → Notification Management. Go through the list and find system applications with suspicious names. Select Disable Notifications for each of them.
| Service | Function | Recommendation |
|---|---|---|
| MIUI Daemon | Statistics collection | Disable notifications |
| Mi Credit | Financial services | Turn it off completely. |
| GetApps | App store | Limit notifications |
| Mi Video | Video player | Disable recommendations |
Be careful when disabling notifications from important system processes, such as System Updates or Security, to avoid missing critical messages about viruses or new versions of the software.
Cleaning the desktop and folders
Redmi Note 9 owners may have noticed a Tools or Recommended folder on their desktop, which contains third-party app icons, a form of advertising that takes up space and distracts attention.
To remove Recommended Apps, press and hold your finger on the folder until the edit menu opens. Select folder settings and turn off the Recommended Apps option. After that, the folder will be clean and you can place your shortcuts there.
Also worth checking out on the desktop widgets: The Cards or News widget often broadcasts advertising content. Remove them with a long tap and replace them with useful weather widgets or watches that don't require an internet connection for basic functionality.
💡
Removing advertising widgets and folders with recommendations returns the purity of the interface and saves mobile Internet traffic.
Additional methods and work with DNS
If the built-in settings aren't enough, you can use more advanced network-level locking techniques. One of the most effective ways is to change the way you do it. DNS-This allows you to block ads in all applications, including browsers and games.
Go to Settings → Connection & Sharing → Private DNS. Select DNS Host Name and type in dns.adguard.com. Save settings. All ad traffic will now be filtered.
dns.adguard.comThis method works well and does not require third-party software installation, however, if you use public Wi-Fi networks with browser authorization (such as hotels or cafes), there may be connection problems at times, in which case the DNS will need to be temporarily returned to Auto mode.
⚠️ Attention: when using third-party DNS Some apps may be slower, and content labeled as advertising may stop loading correctly.
