How to remove ads on Xiaomi Mi9: the complete guide

The Xiaomi Mi9, which is powered by the Snapdragon 855 processor, is still one of the most productive devices in its class, but users are often annoyed by built-in advertising. The company's aggressive marketing is introducing ads into system applications, which reduces the comfort of using the gadget. Fortunately, the MIUI operating system allows you to adjust privacy settings quite flexibly and disable unwanted content.

In this guide, we will discuss all the effective ways to remove ads on the Xiaomi Mi9 phone, from official settings to advanced methods of blocking through DNS. You do not need to be an expert in programming to perform these actions, but care is required when switching system switches. Proper setting will not only clear the screen from banners, but also speed up the interface, saving battery power.

Disabling system advertising through account settings

The first and most important step is to deactivate the MSA (MIUI System Ads) service, which is the system process responsible for collecting user data and displaying targeted ads in the interface, and without disabling this component, all other actions may not be effective, as the ads will return after the reboot.

First, you go to the device settings menu and find the password and security section. There's a key switch that controls recommendations. Find Privacy and scroll down to the ad service block. You need to check the "Get recommendations" box. The system can ask you several times for confirmation, insisting on the benefits of personalized content — ignore those messages and turn off.

⚠️ Note: Once you disable the Receive References feature, the system may ask you to wait 10 seconds before applying the changes. This is the standard delay procedure, just wait until the timer ends and confirm the action.

Next, check the settings of your Mi Account. Go to Settings → Mi Account and select Ads and Privacy. You need to turn off the Personalized Ads option. This action will prevent the company's algorithms from analyzing your actions in the ads applications, and while this will not remove banners completely, they will become less intrusive and more random.

Cleaning up from advertising in standard applications

After the global MSA shutdown, you need to customize each system application individually, as many of them have their own built-in content display modules. Xiaomi Mi9 is particularly active in promoting its services "Conductor", "Music" and "Security", ignoring these settings will lead to the fact that folders and when programs start pop up.

Start with the "Security" app. This is the central memory and antivirus hub that most often shows ads when scanning. Open the app, click on the gear in the upper right corner and find the "Receive recommendations" item. Transfer the switch to an inactive state. It's also recommended to go to the "Clean up" section inside the same app and turn off the "Receive recommendations" option there if it's present separately.

The next step is to get to the file manager. File Manager often shows banner ads at the bottom of the screen or when you open file categories.

• 📁 Open the "Conductor" application".
• ⚙️ Click on the menu (three bars) and select Settings".
• 🚫 Find the "About Application" or "Information" section and disable "Recommendations".
• 🔄 Return to the main menu and in the "Last Files" section also remove unnecessary widgets.

Don't forget the Downloads and Music app. In downloads, ads can pop up after you download the file. Go to the download settings (three dots in the corner) and uncheck the Recommends. In the music app, the same setting is in the profile menu or the player's general settings. These actions will take a few minutes, but will significantly clear the user experience.

Blocking Advertising Through DNS

The most effective method, which does not require third-party software installation, is to use DNS (Domain Name System) with filtering, which blocks requests to known ad servers at the network level, which prevents banners from loading not only in the system, but also in the browser and some games. For the Xiaomi Mi9 with Android 9 and above, this feature is built-in natively.

To activate the protection, go to Settings → Connection and sharing. Find the item "Private" DNS" (Private DNS). The default is "Auto." You have to select "Host Name provider" option. DNS" (Or "manually") and enter the address of a special server. One of the most reliable and free options is the AdGuard service. DNS.

dns.adguard.com

Type this address into the field and save the settings. After that, the phone can lose its Internet connection for a second, and then restore it. If the address is entered correctly, you will see a key icon or the words "Connected" next to the name of the Wi-Fi network or in the status bar, which means that all traffic is now filtered, and requests to advertising domains simply do not pass.

Removal and disabling of system components

For advanced users who want to get the most out of the game, there is a procedure to disable the system packages responsible for analytics and advertising. Unlike a simple switch in settings, this method actually freezes the process, preventing it from starting even in the background, which is especially true for older versions of MIUI installed on the Xiaomi Mi9.

You'll need to access a hidden engineering test menu or use ADB (Android Debug Bridge) from your computer. However, there's an easier way to use the hidden launcher settings. Try typing the ##6485## to check the battery, but for advertising we need the ##86583##. Entering this code (on some firmware versions) automatically includes the hidden "System Ads Switcher" button in the standard settings menu.

If the code doesn’t work, you can use the Activity Launcher app from the Play Market.

1. 🔍 Install and launch Activity Launcher.
2. 📱 Find the "Security" or "Services and Feedback" app in the list".
3. ⚙️ Deploy the list of activities and find the item that contains the word "Ads" or "Recommendation".
4. 🚫 Click on it to open the hidden shutdown menu.

Be careful: Disabling critical system processes can cause your phone to run in an unstable way. Always back up your data before interfering with system activities.

Setting up your browser and cleaning notifications

Often users confuse system advertising with intrusive notifications from sites they accidentally subscribed to in the browser. If pop-ups suddenly appear on the Xiaomi Mi9 screen with the sentence "you won the iPhone" or "virus found", most likely, the problem is not in the system, but in the resolutions of the Chrome or Mi Browser browser.

To clean up, go to Settings → Apps → All apps. Find your primary browser (like Chrome). Go to Notifications. Here you will see a list of sites that have the right to send push notifications. Carefully examine the list and remove any suspicious domains that you do not recognize or look like spam. Usually, just click on the site and select Block or Delete.

It is also recommended to install a high-quality ad blocker directly in the browser. For Chrome on Android, this can be done by changing the DNS settings inside the application itself or installing the Brave or Firefox browser with uBlock Origin addons. This will prevent the loading of advertising scripts on the pages visited, which will also speed up the loading of sites on the Snapdragon 855 processor.

💡

Use the “Traffic Saving” mode in Chrome browser – it passes traffic through Google servers, which automatically cut out some of the advertising debris before loading the page on the phone.
