Xiaomi and Redmi smartphone owners often encounter an intrusive feature that changes lock screen wallpaper and broadcasts ads. This system service is called Mi Show (or Wallpaper Carousel), and it is pre-installed in the MIUI shell by default. On the Redmi 9 model, which remains popular due to the ratio of price and quality, the presence of an extra ad module can annoy users accustomed to a clean interface.
Complete removal of the system component without root rights is impossible with standard Android operating system tools, as it is a secure process. However, there are proven ways to completely disable it, hide the icon from the menu and prevent advertising slides. In this article, we will look at all the options available, from simple settings to advanced methods through the computer.
It is important to understand that Mi Show is not a virus, but part of the manufacturer’s ecosystem to monetize budget devices. However, the user has every right to refuse to use this feature. Below are detailed steps to deactivate the service by various methods.
⚠️ Note: Before making any changes to system settings or using debugging tools, it is recommended to back up important data to avoid accidental loss of information.
Disabling the function through system settings
The safest and easiest way to get rid of adverts on a locked screen is to use a built-in settings menu, which does not require a computer connection and is suitable for most users who want to quickly solve the problem, first you need to find the section responsible for the design of the lock screen.
Go to Settings of your Redmi 9 and scroll down to Always on screen and lock (or just Lock Screen depending on the version of MIUI). Here you will see the Wallpaper Carousel option. This is the switch that activates the Mi Show service. Translate the slider to the "Off" position.
After disabling the main function, the system may suggest that you choose a static image for the lock screen. This is a normal shell reaction. It is also worth checking the theme settings, since some third-party themes can force the functionality of the carousel back.
💡
Disabling the wallpaper carousel switch in the lock screen settings completely stops the slides from showing, but does not delete the application file itself from the phone’s memory.
If the ad continues to appear after the feature is turned off, the "Receive recommendations" option may be activated, and it is located in the same menu, often under the "Carousel settings" subsection. Make sure that all ticks related to content downloads and recommendations are removed, which will prevent new images from loading in the background.
Hiding the application from the application menu
Even after the feature is disabled in the settings, the application icon can remain in the general list of programs, taking up space and a calluse of the eye. To remove the visual trace of the presence of the Mi Show, you can use the application hide feature available in the MIUI shell.
To perform this operation, open the Security app, which is system-based on all Xiaomi devices. Scroll down to Hide apps. The system will request confirmation or password setting if it is the first time. In the list that opens, find the Mi Show or Wallpaper Carousel and activate the switch next to the name.
- 📱 Open the hidden app menu through a long tap on the empty desktop space (in editing mode).
- 🔒 Enter the password you previously set or use your fingerprint to access it.
- ✅ Make sure the switchboard next to the system service is on, which will hide it from the launcher.
This method doesn’t physically delete the file, but makes it inaccessible for a user to accidentally run it, which is especially useful if you have children who can accidentally click on the icon and re-activate the ad impression.
💡
If you can’t find an app in the hidden list, try switching the list view to “All Apps” in the hideout settings, as system processes are sometimes grouped separately.
Using ADB for Deep Deactivation
For users who want to maximize the results and actually remove the application from the system (although files will remain in the system partition, they will stop executing), you will need to use the tool. ADB (Android Debug Bridge: This method requires connecting your smartphone to your computer via a computer. USB-cable.
The first step is to activate the developer mode on your Redmi 9. Go to Settings → About Phone and quickly click 7 times on the MIUI Version. After the message “You became a developer” appears, go back to the main settings menu, go to Advanced Settings → For developers and turn on the Debugging by USB.
adb shell pm uninstall -k --user 0 com.miui.misystemHowever, the Mi Show package often has a different name. To precisely delete or disable, you need to know the specific packet ID. In the case of the Wallpaper Carousel, it is often com.miui.miwallpaper or com.miui.mishow.
adb shell pm disable-user --user 0 com.miui.miwallpaper⚠️ Attention: Use of teams ADB Disabling critical system processes not related to advertising can lead to unstable device operation or cyclical reboot.
Once the command is executed, the application will disappear from the list of installed for the current user. To return everything back if something goes wrong, the command adb shell pm enable is used. --user 0 [package_name]. This method is considered the most effective for advanced users.
Limitation of background activity and permissions
If you don't want to use a computer and complex commands, you can significantly limit the service's malicious, privacy and traffic-related activity through the application management menu. This won't remove the Mi Show, but it will deprive it of the ability to work in the background and consume resources.
Go to Settings → Applications → All apps. Find wallpaper carousel or Mi Show. Go inside and select Battery (or Battery Consumption). Set the mode No restrictions (so the system doesn’t wake it up) or vice versa, Restrict background activity if this option is available in your version of Android. In MIUI, you better choose to limit background activity.
| Parameter | Recommended value | The effect |
|---|---|---|
| Auto-start | Off. | The service will not start when the phone is turned on |
| Permits | All off. | Restriction of access to memory and network |
| Notifications | Off. | Absence of pop-up messages |
| Transfer of data | Forbidden. | Saving traffic and no new advertising |
Also be sure to go to the Permissions item inside the app menu and revoke all rights, especially access to Memory, Phone and SMS. The wallpaper service doesn't need to read your messages or know who you're calling.
☑️ Checking the Mi Show's Limitations
After applying these settings, it is recommended to completely restart the device, which ensures that all running service processes are stopped and the new rules take effect.
Analysis of the impact on the autonomy of Redmi 9
Many users are wondering how much the Mi Show affects the life of the Redmi 9. Given that the device is equipped with a battery capacity of 5020 mAh, one advertising slide will not play a decisive role. However, constant background activity, uploading images through the mobile network and the work of the processor for rendering graphics create a cumulative effect.
The system service periodically turns to the network to update content, even if you are not using your phone, which prevents the processor from going into deep sleep, which is the main reason for battery discharge in standby mode. Disabling the Mi Show often leads to a noticeable improvement in the device’s time in standby mode.
In addition, constantly writing and reading data to an internal drive (picture caching) can theoretically reduce memory life, although on modern eMMC 5.1 drives that are in Redmi 9, this factor is less critical than on older devices.
