How to completely disable wallpaper on the lock screen Xiaomi Redmi 9: official and hidden methods

The lock screen on Xiaomi Redmi 9 is not just a protection against accidental clicks, but also a business card of your smartphone. However, standard MIUI wallpapers (especially with animations or banner ads) can be annoying: they eat up battery power, distract from notifications or simply do not fit into your style. Unlike desktop backgrounds, lock wallpapers in MIUI are tied to system themes and do not always lend themselves to classic removal through the gallery.

Many users face a problem: even after changing the theme or resetting the settings, the wallpaper on the lock remains the same, due to the features of the MIUI shell, where the background of the lock screen can be inherited from an installed theme, system updates or even advertising modules (in regional firmware). In this article, we will discuss all working ways to disable or replace wallpapers, from official settings to hidden commands for experienced users.

It’s important to understand that Redmi 9 came with different versions of MIUI (11 to 14), and the path to settings may be slightly different. If your smartphone is running MIUI 14 with an updated interface, some menu items may be renamed — we’ll show you alternative paths.

Before you start making changes, check the MIUI version in Settings → About Phone → MIUI version. This will help avoid confusion with the location of options.

1. Method: through standard MIUI settings (without root)

The safest method is to use built-in shell tools, which is suitable for most users and does not require technical skills, but it has a limitation: MIUI does not allow you to completely remove the background, but only replace it with another one from the gallery or system themes.

Here's how to do it:

1. Open the settings (cog icon on the desktop).
2. Go to Lock Screen (in some versions of MIUI this is called Lock and Password).
3. Select Lock Screen Wallpaper or Lock Background.
4. Click Change Wallpaper and select a monochrome color from the Colored Backgrounds collection (e.g., black or gray).

If your MIUI version doesn’t have Colored Backgrounds, try installing a minimalist theme from the official theme store:

1. Open the Themes app (icon with brush).
2. In the search, type in the query “minimalism” or “simple background”.
3. Set your favorite theme – it will automatically apply to the lock screen.

⚠️ Attention: B MIUI 12 and later, some themes have built-in ads on the lock screen. To turn it off, go to Settings. → Memory. → Clean and deactivate the option “Recommendations on the lock screen».

If you need to completely remove the background (leave transparent or monochromatic without drawings), this cannot be done by standard means - methods from the following sections will be required.

Method: by means of ADB-Teams (for advanced teams)

If you don't like the limitations of standard settings, you can use Android Debug Bridge (ADB), a deep-tuning tool that doesn't require root rights, but requires command-line permission.

Here's what you're gonna need:

• 🖥️ Computer with Windows/macOS/Linux and installed Xiaomi drivers.
• 📱 Included debugging by USB on a smartphone (Settings) → The phone. → Version. MIUI → 7 times press to unlock the developer mode, then Settings → Additionally. → For developers → Debugging by USB).
• 🔗 Utility. ADB Platform Tools by Google.

Step-by-step:

1. Connect Redmi 9 to your computer via USB and select File Transfer mode.
2. Open the command prompt (or Terminal on macOS/Linux) in the ADB folder.
3. Enter the command to check the connection: adb devices If the device appears in the list, go further.
4. Execute the command to disable the lock wallpaper: adb shell settings put global lock_screen_wallpaper_enabled 0
5. Reboot your smartphone: adb reboot

After rebooting, the lock screen should turn black or gray (depending on the topic). If the background remains the same, try to do additional:

adb shell settings put secure lock_screen_wallpaper ""

Install Xiaomi drivers on PC

Enable debugging over USB on your phone

Download ADB Platform Tools

Connect the phone in the mode "File transfer"

Check the connection of the adb device team-->

⚠️ Attention: Teams ADB If the lock screen has stopped working correctly after the changes (for example, notifications or hours have disappeared), return the standard values with the command: adb shell settings delete global lock_screen_wallpaper_enabled

This method works on most versions of MIUI, but in MIUI 14 Xiaomi tightened control over system parameters. If the commands did not work, try an alternative method using third-party applications.

Method: Third-party annexes (with reservations)

There are apps on Google Play that promise to change or remove lock wallpaper, but most don’t work on MIUI because of shell limitations.However, some utilities can help get around these limitations.

Recommended applications (checked on Redmi 9):

• 🎨 Wallpaper Changer – allows you to set a monotonous background, but requires permission to change system settings.
• 🔧 Lock Screen Wallpaper Changer – This is a changer ADB In the background (you must first give permission through the computer).
• 🖼️ Muzei Live Wallpaper - can put on top of standard wallpaper monotonous layer (does not remove the background completely, but visually it will hide it).

Instructions for Wallpaper Changer:

1. Install the app from Google Play.
2. Open it and select the option “Change lock wallpaper”.
3. Download a monochromatic image (for example, a black square of 1080×2340 pixels) or select from built-in options.
4. If you request ADB permission, follow the instructions in the previous section.

⚠️ Note: Apps from third-party sources (not from Google Play) may contain malicious code. APK-Files from unknown sites, especially if they promise “100% removal of wallpaper without root” – this is often a scam.

If none of the applications worked, the last method is manual editing of system files, but this will require an unlocked bootloader and root rights.

💡

Before installing third-party applications to set up lock, back up your data through Settings → Additional → Backup and Reset. This will help restore the system if something goes wrong.

4. Method: manual removal of wallpaper through root (for experienced)

This is the most radical method, and it is only suitable for those who are willing to risk the stability of the system, and it involves obtaining root rights and editing system files, which can lead to:

• 🚨 Loss of warranty (if it is still valid).
• 🔄 Work failures MIUI (For example, system applications will no longer be updated).
• 🛡️ Security issues (some banking apps will not work).

If you are ready for this, follow the instructions:

1. Unlock the Redmi 9 bootloader through the official Mi Unlock tool (you will need a Xiaomi account and wait 7-30 days).
2. Install custom recovery (such as TWRP) and get root rights through Magisk.
3. Using a root-access file manager (such as Root Explorer) go down the path: /data/system/users/0/ Find files with names: lockscreen_wallpaper.jpg lockscreen_wallpaper_thumb and remove them.
4. Reset the device.

Once these files are deleted, the lock screen will become completely black, but the system notifications and the clock will remain in place. If the background returns after the reboot, then MIUI will restore it from the backup, in which case you will have to repeat the procedure or use the Magisk module to block the changes.

5. Alternative approach: disabling animations and visual effects

If your goal is not to remove the wallpaper completely, but to make the lock screen less intrusive, you can turn off the animation and visuals. It won't remove the background, but it will make it static and less noticeable.

How to do this:

1. Go to Settings → Lock screen → Lock style.
2. Choose Classic instead of MIUI or Animation.
3. Turn off the options: 🌈 «Animated wallpaper» 🔄 «Automatic wallpaper change» ✨ «Effects of blocking»

Settings → Display → Animation of the system

No animation.

0.5x

These changes will make the lock screen minimalistic even if the background remains. For example, if you had an animated theme with moving elements, after turning off the animation, it will become static.

You can also remove extra elements from the lock screen:

• 📱 Turn off Settings. → Lock screen → Show notifications if they interfere.
• 🕒 Hide the clock: Settings → Lock screen → Hours and date → Clock style → No.
• 📊 Remove indicators: Settings → Lock screen → Status line → Hide.

💡

Disabling animation not only makes the lock screen easier, but also slightly increases battery life by reducing the load on the processor.
