How to remove ads on Xiaomi Redmi 9C NFC

Xiaomi’s smartphones are famous for their value for money, but owning a budget device like the Redmi 9C NFC often involves intrusive display of advertising content. System advertising can pop up in the most unexpected places: in the standard menu, when opening apps or even on the lock screen.

Owners of the Redmi 9C NFC face this problem regularly, since the MIUI shell (or the newer HyperOS) is set to aggressive marketing by default. You can remove ads completely without resorting to complex flashing methods or obtaining root rights. It is enough to consistently go through several settings and disable key services responsible for displaying banners.

In this guide, we will look at every aspect of cleaning the interface from garbage. A critical step is to disable the MSA service (MIUI System Ads), without which other actions may not be effective. We will analyze the settings of each system application, clear the recommendations in folders and configure the browser. Follow the instructions carefully to return your gadget to clean and speed.

Disabling the MSA System Service

The first and most important step is deactivation. MSA — The service that is responsible for displaying ads throughout the system, and without disabling this component, any other manipulations will be temporary. MIUI The process is hidden behind multiple menu levels so that the user can’t easily find it.

To start, go to Settings, then select Passwords and Security. Next, look for Data Access. In the app list that appears, find the msa and turn off the switch opposite it. The system will warn you that after you turn off some features may not work properly, but for the average user it does not matter.

⚠️ Attention: When you try to shut down a service, the system may display a countdown timer several times (usually 10 seconds) and suggest that you leave it as it is. Do not succumb to provocations and wait for the timer to end, then press "Disable".

After the MSA is disabled, it is also recommended to restrict Internet access for other system services such as Mi Credit and GetApps if you do not use them, which will prevent the ad modules from loading in the background.

Setting up the desktop and folders

The second step of cleaning is the visual part of the interface, and Redmi 9C NFC owners often notice that when they open the application folders at the bottom of the screen, they get recommendations for installing games or utilities, and this works through a built-in recommendation service that can also be disabled.

Go to Settings and select Desktop. At the bottom of the list, find the Recommendation option and put the slider in an inactive position. This action will remove the ad bar from the folders and free up space on the screen. You can also turn off Wallpaper Carousel if you don't need it, as it often contains news blocks.

Also, you should check the widget settings, some of which, like Music or Security, can download content from the Internet, and cleaning up the desktop from unnecessary widgets will not only remove ads, but also speed up the launch of the system.

• 📱 Open the desktop settings through a long press on an empty area.
• 🚫 Find the "Recommendations" switch and turn it off.
• 🗑️ Remove unused widgets that may contain news feeds.
• 🔄 Restart the launcher to apply changes.

💡

If after disabling recommendations, the advertisement in the folders remained, try to clear the cache of the Desktop application in the Apps menu.

Cleaning the "Security" and "Downloads" application

Xiaomi’s security app is one of the main sources of intrusive notifications, which regularly offers to “speed up” the phone, clear the memory or check viruses, often accompanied by banner ads, and to get rid of this, you need to dig into its internal settings.

Open the Security app, click on the settings gear in the top right corner. Scroll down to Get recommendations and turn off this feature. It's also recommended to go to the Alerts section and remove the boxes related to advertising and promotions, leaving only critical virus warnings.

A similar situation is observed in the Downloads app. When you open the list of downloaded files, users often see banners at the bottom of the screen. To remove them, open the app, click three dots in the corner, select Settings and turn off Show recommended content.

Removing Advertising in a Standard Browser

The standard MIUI Browser (or Xiaomi Browser) browser is often criticized for aggressive newsfeed ads and push notifications. Even if you rarely use the app, it can work in the background. The best way is to turn off notifications completely or replace them with an alternative, like Chrome or Firefox.

If you prefer to stay in the ecosystem, open your browser, go to the menu (three bars) and select Settings. Next, select Privacy and Security. You must turn off Personalized Recommendations and Site Notifications. You can also select Empty Page from the Home Page section to avoid seeing the news feed.

It is also important to check browser permissions. In the phone system settings, find Apps → All Apps → Browser → Notifications. Turn off all notification categories except possibly Downloads if necessary.

Limiting personalized advertising

Xiaomi, like many other tech giants, collects data about your preferences for targeted advertising. On the Redmi 9C NFC, you can limit this fee, which will also reduce the number of relevant but annoying offers.

Go to Settings → Passwords and Security → Privacy. Go to Ad Services. Here you will see the Personalized Advertising switch. Turn it off. The system will warn you that the ads are not going anywhere, but will become less relevant. However, when combined with MSA disabling, this gives you a great result.

Also in this section, it is worth checking which applications have access to the advertising ID. It is recommended to reset the advertising ID by clicking the appropriate button to break the connection with the previously collected user profile.

⚠️ Warning: After resetting your ad ID in the early days, you may see random ads until the system realizes that targeting is off.

Resetting Advertising Identifier Settings

Sometimes simple switches don't work right away, and you need to reset your ad settings more deeply, especially if you've bought your phone by hand or reflashed it, and it takes just a minute, but it can help you reset your ad profile.

In the same Advertising Services menu, find the Reset Advertising ID button. Click on it and confirm the action. This will create a new, clean ID for your device that is not related to your past activity. In some versions of MIUI, this feature can be found via Settings → Google → Advertising.

After resetting, it is recommended not to immediately log into the accounts of services that actively use data for targeting, or do so after full system setup, which will help to maintain the "purity" of the advertising profile.

Using DNS to Block Advertising

For advanced users who want to remove advertising not only in the system, but also in the browser and some applications, an effective method is to change the system. DNS-It doesn't require third-party applications to be installed and works at the network connection level.

Go to Settings. → Connection and Sharing (or Wi-Fi). Find a Private Item DNS (Private DNS). Select the mode "Host Name provider" DNS" and enter the address: dns.adguard.com. Save settings.

This method filters traffic and blocks requests to known ad servers. On Redmi 9C NFC, this can significantly speed up page loading in the browser and remove banners from many free apps.

• 🌐 Go to the connection settings.
• 🔑 Select "Private" DNS".
• ✍️ Enter the address dns.adguard.com.
• ✅ Save and check the result in the browser.

⚠️ Attention: Use of third-party DNS It can cause some applications to fail (e.g. carrier services or LANs). If you have problems accessing the Internet, return your settings. DNS in the "auto" position".
