How to change the sound of the screen lock on Xiaomi: all the ways

The screen lock sound on Xiaomi smartphones is a small but important detail that can be both fun and annoying. Standard tunes in MIUI often seem too loud, monotonous or just don't fit your style. Fortunately, the manufacturer has envisaged several ways to replace them - from built-in tools to install custom sounds through the file system.

In this article, we will discuss all the current methods for changing the lock sound for Redmi, POCO and Xiaomi devices based on MIUI 12/13/14, including hidden settings and bypassing system constraints. You will learn how to replace the sound through the standard menu, where to download safe tunes, and what to do if the desired file does not appear in the list of available ones, and also why some sounds may not play after replacing and how to fix it.

Why standard block sounds don’t suit users

By default, Xiaomi offers a limited set of lock sounds, which are often criticized for:

• 🔊 High volume – many users say that standard signals are too sharp, especially in quiet rooms.
• 🎵 Uniformity - in MIUI You can’t choose a tune from a music library, only from a fixed list.
• 📱 Discontent with the theme of design – the sound of the lock can be dissonant with the chosen theme or wallpaper.
• 🔄 Lack of flexibility – you can’t configure different sounds to lock and unlock (unlike some custom firmware).

Also, after MIUI updates, the user's audio settings are sometimes reset and you have to reconfigure everything, and on some models (such as the POCO F3 or Redmi Note 11), the list of available sounds may vary depending on the firmware region.

Method 1: Replace sound with standard MIUI settings

The easiest and safest method is to use the system’s built-in tools, and it’s suitable for most devices on MIUI 12 and up, including the Xiaomi 13, Redmi Note 12 and POCO X5.

Instructions:

1. Open the Settings app (the gear icon on the desktop).
2. Go to the section Sound and vibration.
3. Select the screen lock sound (some firmware may call it Lock Sound or System Sounds).
4. In the list of available sounds, tap the right option. To listen, click on the play button on the right.
5. Confirm the choice by pressing OK or going back.

If you don't have the right sound on the list, you can add your file.

• 📁 Place the audio file in format.mp3,.ogg or.wav in folder /MIUI/sound/ internal.
• 🔄 Restart the device (sometimes required to update the sound list).
• 🔊 Return to the lock sound settings – your file should appear in the list.

File in format MP3/OGG/WAV|Duration no longer 5 seconds|Volume normalized (not clicked)|File is in a folder. /MIUI/sound/-->

It's important: MIUI maintains sounds for a duration of 5 If the file is longer, the system can crop it or not play it at all. Also make sure the file name does not contain Cyrillic characters or spaces - use Latin and underline (e.g., use the name of the file, my_lock_sound.mp3).

Method 2: Using a file manager to manually replace

If the standard method didn't work (e.g., your file doesn't appear in the list), you can manually replace the system sound, which requires root rights or ADB, but gives you more freedom.

Algorithm of action:

1. Download and install a file manager with access to system folders (for example, MiXplorer or Solid Explorer with root mode enabled).
2. Go to /system/media/audio/ui/ This is where all MIUI system sounds are stored.
3. Find files with the names: lock.ogg – lock sound; unlock.ogg – unlock sound (if supported).
4. Back up the original files (copy them to another folder).
5. Replace them with your files, while observing: 🔄 Name matching (for example, yours) my_sound.mp3 It should be renamed lock.ogg). 🎵.ogg format (recommended for compatibility). 📏 File permissions: 644 (rw-r--r--).

Reset the device.

Critical! Incorrectly replacing system files can cause MIUI to malfunction, including a cyclical reboot. If the phone starts to glittle after the sound change, return the original files from the backup.

Method 3: Applications for customizing sounds

If you don't want to mess with the file system, you can use third-party apps that allow you to change lock sounds without root rights, but have limitations:

• 🛡️ Require permission to access notifications and special features.
• 🔋 Can drain the battery faster (due to background work).
• 📱 Not all apps are compatible with the latest versions. MIUI.

Top.-3 tested applications:

Instructions for Zedge:

1. Install and open the application.
2. In the menu, select the Notification Sounds.
3. Find the sound you like and click Set.
4. In the list of options, select Lock Sound (if there is no such option, the sound will have to be set through the MIUI settings manually).

💡

If the app doesn’t see lock sounds in the destination list, try downloading the file first, then manually place it in the /MIUI/sound/ folder and restart the phone.

Problems and Solutions: Why the Sound Doesn't Change

Sometimes after all the manipulations, the locking sound remains the same, and let's look at the typical causes and ways to eliminate them:

If you have replaced the sound through system files but it is not playing, check:

• 🔊 File rights: 644 must be used to read the file).
• 📁 The path to the file: some firmwares look for sounds in /system/product/media/audio/ui/ instead of the standard path.
• 🔄 Version MIUI: into MIUI 14 the structure of system sounds has changed – it may need a replacement in another folder.

💡

On dynamic memory devices (such as Xiaomi 12T), system sounds can be stored in /product/media/. Use ADB or root conductor to find the exact path.

How to Recover Standard Lock Sound

If you're not comfortable with the sound experiments, you can always go back to the factory settings, and you can do this in two ways:

1. Through MIUI settings: Go to Settings → Sounds and Vibrations → Screen Lock Sound. Select Default or MIUI (name may vary).
2. Through System File Recovery: If you have manually replaced files, return the original versions from the backup (see manual replacement section). or run the command via ADB: adb shell restorecon /system/media/audio/ui/lock.ogg

On some devices (such as the POCO X3 Pro) after resetting sounds, you may need to reboot or clean the MiuiSystemUI cache further:

adb shell pm clear com.miui.home

💡

If it still doesn’t play back after returning standard audio, check if it’s turned off in the availability settings (Settings → Special Features → Sounds).

Safety and Risks of Changing System Sounds

Replacing the block sounds is a seemingly harmless procedure, but it can have unexpected consequences.

⚠️ Attention! On devices with a locked bootloader, manually changing system files (even sounds) can trigger the Anti-Rollback protection, in which case the phone will stop booting and you will need a complete flashing through the Fastboot.

Other potential risks:

• 🔄 Cyclical boot: if the sound is not replaced correctly (for example, putting the file with the wrong rights in the system folder), MIUI It might be stuck on the logo.
• 🛡️ Warranty Violation: Manual modification of system files (especially root-rights) may be grounds for denial of warranty service.
• 🔊 Conflicts with updates: after the update MIUI Your custom sounds may disappear or stop working.

To minimize the risks:

• 📁 Always back up your original files before replacing them.
• 🔧 Use reliable file managers (e.g. MiXplorer or other file managers). FX File Explorer).
• 🔄 Before experimenting, check your model’s compatibility with the method you choose (see forum reviews). 4PDA or XDA-Developers).
