Removing Advertising on Xiaomi Redmi 9A: Lock screen

Users of Xiaomi’s budget smartphones often encounter intrusive content that appears in the most unexpected places. Especially annoying when banner ads or news feeds cover up useful information directly on a locked device. Owners of the Redmi 9A model are no exception, since the MIUI shell by default contains many integrations that require manual adjustment.

Fortunately, most of these elements can be deactivated without getting root access rights or flashing your device.You don’t need to be a mobile tech expert to get back a clean interface. In this article, we’ll look at specific steps to help you remove ads on the Xiaomi Redmi 9A and make it more comfortable to use the gadget.

The main source of unwanted content is in the system services that are responsible for marketing emails and personalized recommendations. Understanding how this system works will allow you to pinpoint the redundant. Next, we will look at a step-by-step algorithm that will give you back control of the lock screen.

The Nature of Intrusive Content in MIUI

Before you start disabling, you need to figure out what causes advertising materials to appear. The system is based on a service called MSA (MIUI System Ads), which aggregates data about your preferences, and this component is responsible for (push) notifications and banners in different sections of the interface.

In addition, the lock screen itself often contains Horoscope, News, or Video widgets that download content from the Internet, which may look like system widgets but are essentially channels for distributing ads. Disabling one component may not be complete, so a comprehensive approach is needed.

⚠️ Note: Complete removal of system components may lead to unstable operation of some applications. It is recommended not to delete files forcibly, but only to disable their functions through settings.

It’s important to understand that Xiaomi subsidizes the value of its devices through ad integrations, which is why on budget models like the Redmi 9A, marketing elements are more pronounced than in flagship lines.

Disconnecting MSA Service

The first and most important step is to deactivate the primary marketing service, and without disabling the MSA, the rest of the settings may fail or temporarily stop working, a process that requires careful attention as the system will try to convince you to keep the service active.

To start, go to your smartphone's settings menu, and you need to find the password and security item, and depending on the firmware version, the path may vary slightly, but the logic remains the same for all MIUI-based devices.

Search the Authorization and Security section in the list, and you'll need to find Advertising or MSA Service inside the menu. Once you log in, you'll see the switch that's activated by default. Click on it to deactivate the service.

The system will give you a warning window with a countdown timer, you will have to wait until the time ends (usually 10 seconds) and press the "Disable" button. If you press the button ahead of time, the action will not be performed. Repeat the procedure if the first time failed.

Setting up the lock screen and wallpaper carousel

Often, ads on a locked Redmi 9A screen appear because of the Wallpaper Carousel feature, which automatically changes the background image and shows news blocks, and to remove these elements, you need to change the lock theme settings.

Go to Settings and select Lock Screen, and you're interested in the Wallpaper Carousel option, and log in and switch to "Off" and this action will return the static image you set yourself.

If you want to leave the wallpaper change but remove the ad blocks, look inside the Carousel settings for Receive recommendations or a subscription tablet. Disabling these options will only leave the visual part without text debris. However, completely disabling the service guarantees a clean screen.

It’s also worth checking the settings of the wallpaper itself. Sometimes third-party themes downloaded from Themes store may contain embedded ads. If the problem occurs after a change of design, try returning a standard Classic or Default theme.

Management of system applications

Advertising content is often streamed through standard applications such as Explorer, Cleanup, Music or Security, and these programs have their own notification settings that need to be disabled separately from the general system settings.

Let's take an example of the Security app. Open it, click on the settings gear in the top right corner. Find the Receive recommendations section and turn it off. Similar steps should be taken for the Explorer app (setting menu → About application → Get recommendations).

For Downloads, the path is to open the app, click three dots in the corner, select Settings, then Show recommended content, and turn off the switch, which will remove the ads from the downloads and notifications folder.

💡

Use Do Not Disturb mode at night to block any pop-up notifications, even if the ads aren't completely disabled.

Remember that updates to these apps through the GetApps store may return default settings. Check the menus after major system updates periodically to help keep the device clean.

Hidden settings of the developer and ADB

For advanced users who don't have enough standard methods, there are deeper ways to clean the system, which involves using USB debugging and a computer, and this method allows you to disable components that are hidden from the average user.

To activate the developer mode, go to About Phone and quickly press 7 times on the MIUI version. After that, a new section Additional → For developers will appear in the settings menu. Enable Debugging over USB there.

By connecting the phone to a computer, you can use ADB commands to remove or freeze ad packets, for example, a command to disable MSA via ADB looks like this:

adb shell pm disable-user --user 0 com.miui.msa.global

⚠️ Attention: Use of teams ADB It requires caution. Disabling the system packages required for the OS to work can cause the device to reboot cyclically, and you can find the option to Enable Keyboard Input (to debug), but it does not affect advertising. If you are not sure of your actions, it is better to limit yourself to software methods of disabling through the interface.Resetting the advertising ID Another effective step is resetting the advertising ID.
