How to completely disable ads on Xiaomi Redmi 9T: from system banners to push notifications

Xiaomi Redmi 9T is one of the most popular budget smartphones, but its owners often face intrusive advertising in the interface MIUI. Banners in settings, push notifications from system applications, advertising in the menu "Security" - all this spoils the impression of using the device. Fortunately, there are several ways to reduce or completely remove advertising without having to get root rights.

In this article, we’ll look at 5 proven methods, from standard MIUI settings to hidden developer settings. It’s important to understand that some methods may require resetting individual applications or even completely flashing them — so read the warnings carefully before you act. Also note that after major MIUI updates, the paths to some settings may change, but the general logic remains the same.

If you’re willing to spend 10-15 minutes setting up, you can get rid of 90% of ads on your Redmi 9T. Start with the simplest and safest methods, and then move on to more radical solutions.

1. disable personalized advertising in MIUI settings

The most obvious and safe way to do this is to deactivate personalized ads directly in your system settings, which won’t remove all ads, but will significantly reduce the number of targeted banners that Xiaomi displays based on your activity.

Go to: Settings → Xiaomi Account → Mi Account → Personalization and Advertising

Here you need to turn off the following switches:

• 🔍 Personalized recommendations are the main source of targeted advertising
• 📊 Use Analysis – Prevents data collection about your activities in the system
• 📢 Advertising Notifications – Blocks Xiaomi’s Push Ads

After disabling these settings, restart the device. The effect will not be noticeable immediately, but after 1-2 days the amount of advertising in the system menus and notifications will decrease by 30-40%. Unfortunately, this method does not remove banners in the Security, Themes and Mi Video applications - they will require additional actions.

2. Reset advertising ID (Google and MIUI)

Each Android device is assigned a unique Advertising ID, which is used to track ad impressions, and resetting that ID won’t remove the ads completely, but will reset the accumulated data about your preferences, making banners less relevant (and perhaps less intrusive).

To reset Google Advertising ID:

1. Open Settings → Google → Advertising
2. Click Reset Advertising Identifier
3. Confirm the action.

Resetting MIUI Advertising ID (less known, but no less effective):

• 📱 Go to Settings. → The phone.
• 🔨 5 times press the version MIUI, activate the developer mode
• 🔧 Back to Settings → Additionally. → For developers
• 🔄 Find the item Reset the Advertising ID MIUI and press it.

This method is especially useful if you notice that ads become “smarter” over time. Once you reset your ID, the system will perceive your device as new and the targeted ads will temporarily disappear. However, after 1-2 weeks, Xiaomi will start collecting data again, so the procedure is recommended to repeat once a month.

💡

If the Reset MIUI Ad ID option is not in the developer menu, upgrade MIUI to the latest version or use an alternative method from the next section.

3. Disabling advertising in system applications

The main sources of advertising on Redmi 9T are Xiaomi’s standard apps: Security, Themes, Mi Video, Mi Browser and Cleaner. Each has its own ad settings that can be turned off.

Here is a step-by-step instruction for each application:

Once you have disabled these settings, restart each app. It is important to understand that some menu items may not be available depending on the version of MIUI. If you do not find the settings specified, try updating the app through Google Play or the MIUI App Store.

4. Blocking Advertising via DNS (without root)

One of the most effective ways to block ads at the system level is to change the system. DNS-This method intercepts requests to ad servers and redirects them to "nowhere", which allows you to block most banners, including those embedded in system applications.

To configure an alternative DNS:

1. Go to Settings → Connections and Sharing → Private DNS
2. Select the host name of the private DNS provider
3. Enter one of the addresses: dns.adguard.com (AdGuard DNS) dns.nextdns.io (NextDNS) 1dot1dot1dot1.cloudflare-dns.com (Cloudflare)

Save the settings and restart the phone

After applying the changes, check the Internet — some sites may open slower. If the speed has dropped significantly, try another one. DNS-This method blocks not only Xiaomi ads, but also banners in the browser, social networks and most applications.

Important: Some banking applications and services (e.g. SberBank Online or Tinkoff) may block access when using third-party services DNS. In this case, temporarily disconnect the private DNS or add exceptions to the selected settings. DNS-provider.

5. Radical methods: disabling system applications

If previous methods have failed, more serious measures can be taken, such as disabling or removing system applications responsible for displaying ads, which requires caution, as improper actions can lead to unstable phone operation.

List of applications that can be safely disabled (without root):

• 🚫 com.miui.analytics – analytics collection (responsible for targeted advertising)
• 🚫 com.xiaomi.midrop – Mi Drop (advertising when transferring files)
• 🚫 com.miui.videoplayer - Mi Video (banners in player)
• 🚫 com.miui.player – Music (advertising in audio player)
• 🚫 com.miui.bugreport – error reports (sometimes showing ads)

To turn off:

1. Activate the Developer Mode (as in Section 2).
2. Go to Settings → Applications → Application Management.
3. In the top menu, select ⋮ → Show all the processes.
4. Find an application by name or package (e.g. com.miui.analytics).
5. Click Disable (Do not "Delete"!).

⚠️ Warning: Do not disable applications called com.android, com.google or com.qualcomm, which can cause critical system failures. Also do not delete com.miui.home or com.miui.securitycenter, otherwise the phone may stop loading.

💡

Disabling system applications is the most effective way to remove ads, but it requires caution: always back up data before changes and only disable applications that are not critical to the system.

6. Alternative firmware: complete elimination of advertising

If you are ready to take drastic measures, then flashing the phone to custom firmware (for example, LineageOS or Pixel Experience) will completely remove all built-in MIUI advertising mechanisms. This method is only suitable for experienced users, as it requires unlocking the bootloader and can deprive you of warranties.
