How to completely disable wallpaper on the lock screen Xiaomi Redmi Note 8T

The lock screen Xiaomi Redmi Note 8T — It's not just a random press protection, it's also a visual calling card for a smartphone. MIUI, Those that are automatically duplicated from the home screen or downloaded from a theme store are not always comfortable with users. AMOLED-In this article, we're going to show you the display, some people are going to get rid of the intrusive images for privacy, and some people are just tired of the monotony. MIUI Alternative methods for advanced users.

It's important to understand that the Redmi Note 8T is based on MIUI, Xiaomi's proprietary shell, which is updated regularly. So some of the ways from old instructions (for example, through the "Themes" menu) may not be relevant. We tested all the methods on the latest versions of MIUI 12-14 and guarantee that they work. If you use custom firmware (such as Pixel Experience or LineageOS), the algorithm of actions will be different - we will also discuss this separately.

Why you can’t just remove the wallpaper in the standard way

MIUI was originally designed as a closed system with limited customization capabilities. Unlike naked Android, where the user can freely change the background of the lock regardless of the main screen, Xiaomi has many of these settings linked together, and here are the key reasons why there is no simple solution to remove wallpaper:

• 🔗 Thematically linked: MIUI It uses a single design theme, where the lock background is part of the overall style, and you can't disable it separately without resetting the whole theme.
• 📱 Shell Limitations: In Lock Screen Settings (Settings) → Lock screen) only options for changing the picture are available, but not completely removing it.
• 🛡️ Security Policy: Xiaomi blocks deep changes to system files without unlocking the bootloader to prevent smartphone malfunction.
• 🔄 Automatic Sync: If you use a Mi Account, wallpaper can sync between devices, recovering from deletion.

Another caveat is that on the Redmi Note 8T with MIUI 12.5 and later, the lock wallpaper is stored in a secure part of the system, and it can't be removed through a standard file manager, and this is done to prevent updates from crashing, but there are workarounds, and we'll look at them.

⚠️ Attention: Before any manipulation of system files, back up the data. ADB Manual configuration editing can lead to a cyclic reboot (bootloop) if an error is made.

Method 1: Disconnect via MIUI settings (without root)

The safest method, which doesn't require any additional tools, is suitable for most users, but has a limitation: instead of wallpaper, you get a black background or a standard MIUI gradient.

1. Open Settings and go to the Lock Screen section.
2. Slip on the lock screen wallpaper (or lock background depending on the MIUI version).
3. In the window that opens, select Standard Wallpaper or Background Color.
4. Choose the darkest shade (such as Black or Dark Gray) and confirm the choice.

If your MIUI version does not have a background color option, try the following algorithm:

• 📌 Go to Settings. → Wallpaper.
• 🎨 Choose the Color or Gradient category.
• 🖤 Apply a monochromatic dark background to all screens (including locking).

Make sure your smartphone is over 30% charged.

Turn off automatic theme change in Settings → Topics

Check that the device has enough free memory (minimum 500 MB)

This method does not physically remove the wallpaper, but only replaces it with a minimalist option. If you need to completely remove the background (for example, to save charge or eliminate display bugs), move on to the following methods.

Black (saves charge)

Standard MIUI wallpaper

Dynamic wallpaper

Method 2: Using ADB for deep settings

If you need to completely disable the background (including system wallpaper), you will need to connect to a PC and use Android Debug Bridge (ADB).This method works on all versions of MIUI, but requires unlocking Developer Options.

First, prepare your smartphone:

1. Activate Developer Options: Go to Settings → About Phone and tap on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect the Redmi Note 8T computer-to-computer USB-cable (use the original cable for connection stability).

Now run commands in the terminal (or Command Prompt on Windows):

adb devices


adb shell settings put global lock_screen_show_notifications 0




adb shell settings put secure lock_screen_allow_private_notifications 0




adb shell pm disable-user --user 0 com.android.themes

The last command disables the Themes system application, which is responsible for lock wallpaper, but this can cause other MIUI visual elements to fail. To get it back, use:

adb shell pm enable com.android.themes

⚠️ Note: Disabling system applications through ADB If after executing commands, the lock screen becomes glitchy (for example, notifications or hours are not displayed), reset the lock screen settings via Settings → Annexes → Application management → Lock screen → Warehouse → Clear the data.

Method 3: Manual editing of system files (for advanced)

This method is only suitable for users with an unlocked bootloader and installed TWRP or other custom recovery. It allows you to remove wallpaper physically, replacing it with a blank file. The advantage is that the background of the lock will become completely transparent (if the theme is supported), and the disadvantage is a high risk of errors.

Instructions:

1. Download and install on the PC ADB & Fastboot Tools and Notepad++ (for configuration editing).
2. Connect the Redmi Note 8T to your PC and go to Fastboot mode (press Power + Volume Reduction when the phone is off).
3. In the terminal, run the command to mount the system partition: fastboot mount system
4. Go to the lock wallpaper folder (usually /system/media/theme/default/wallpaper) and delete the files with the.jpg or.png extension that are responsible for the background.
5. Create an empty file lockscreen_wallpaper.png (size 1×1 pixels and place them in the same folder.
6. Access rights: Adb shell chmod 644 /system/media/theme/default/wallpaper/lockscreen_wallpaper.png

Once rebooted, the lock screen will display an empty background or default color (depending on the topic), the most radical and suitable for enthusiasts prepared for potential risks.

Method 4: Third-party applications for customization

If you don't want to mess with ADB or system files, you can use third-party utilities, but there are two critical points:

1. Security: Many applications to change lock wallpaper require rights SYSTEM_ALERT_WINDOW or BIND_WALLPAPER, What can be used to display advertising or collect data.
2. MIUI Limitations: Xiaomi blocks deep changes through third-party programs, so most utilities only work on rooted devices.

List of tested applications (tested on Redmi Note 8T):

• 📱 Wallpaper Changer (from Google Play) – allows you to install different wallpapers on the main screen and lock, but requires root for full control.
• 🎨 Muzei Live Wallpaper – supports dynamic wallpaper, but on the other hand, MIUI It may conflict with system services.
• 🔧 Lockscreen Wallpaper Changer (requires Xposed Framework) is the most flexible option, but difficult to set up.

Before installing any application:

1. Check out reviews on 4PDA or XDA Developers (especially MIUI).
2. Use VirusTotal to scan APK-file.
3. Create a restore point in TWRP (if installed).

💡

If after installing a third-party application, the lock screen began to slow down, clear the system launcher cache (com.miui.home) through Settings → Applications → Application Management.

Features for custom firmware (Pixel Experience, LineageOS)

If you use the Redmi Note 8T with alternative firmware (not MIUI), the algorithm will be different. In most custom builds (such as the Pixel Experience or Havoc-OS), lock wallpaper is customized independently of the home screen.

1. Open Settings → Personalization → Style and Wallpaper.
2. Select the Lock Screen and set any background (including solid color).
3. Use the complete removal of the wallpaper ADB-Adb shell cmd wallpaper clear --lock

On firmware such as LineageOS, the option background transparency is also available, which allows you to make the lock screen semi-transparent (useful for the use of a computer). AMOLED-But consider the displays:

• 🔄 After updating the firmware settings can be reset.
• 🔧 Some builds require additional Magisk modules for full customization.

Frequent problems and their solutions

When changing the wallpaper lock users Redmi Note 8T often encounter errors.

• 🔄 Wallpaper returns after rebooting: This is due to synchronization of Mi Account. Turn it off in Settings → Accounts. → Mi Account → Synchronization → Topics.
• ⚡ The lock screen started to lag: Clear the cache of the com.android.systemui application through ADB: adb shell pm clear com.android.systemui
• 🖼️ The background is displayed blurry: MIUI It automatically applies blur to the lock wallpaper. ADB: adb shell settings put global lock_screen_blurs_effect 0
• 🔒 Fingerprint not working: After changes to system files, you may need to re-register fingerprints in Settings → Lock screen → Fingerprint.
