Why the standard unlock sound is annoying – and what to do about it
The sound of unlocking the screen on Xiaomi is like an alarm clock in the morning: it is either ignored or it freaks out. At first it seems that the default melody ("Mi-sound") is quite harmless, but after a month of use you start to catch yourself thinking that you subconsciously shudder every time the phone makes this familiar ding-don, especially annoying when the smartphone unlocks in a quiet room - a library, a conference room or at night next to a sleeping child.
The problem is that MIUI (the Xiaomi shell) doesn't change that sound through standard settings, unlike calls or notifications. The manufacturer believes that system sounds should remain the same for "uniform user experience." But that doesn't stop thousands of Redmi Note 12, POCO X5 or Mi 11 owners from looking for workarounds. Spoiler: there are — and there are at least three.
In this article, we will discuss all working methods, from simple (replacement through hidden settings) to radical (manual editing of system files), and also explain why some users lost the unlock sound after upgrading to MIUI 14 - and how to return it.
Method 1: Replacement by “Themes” (official method for MIUI 12–14)
The safest way is to use the built-in Themes app, which is suitable for most models on MIUI 12 and later, but with reservations: unlock sounds are not available in all themes, and their choice is limited, however, this is the only method that does not require root or third-party permissions.
Instructions:
- 📱 Open the “Themes” app** (icon with brush and palette).
- 🔍 In the search bar, enter unlock sounds or unlock sounds.
- 🎵 Choose your favorite theme from the results (e.g., “Nature Sounds” or “Retro Games»).
⚠️ Warning: Some themes change all system sounds (calls, notifications, alarm clocks) If you only need to change unlock, after applying the theme, manually return the rest of the sounds to Settings. → Sounds and vibrations.
Method 2: Manually add sound through file manager (no root)
If the Themes don’t have a suitable option, you can download your sound in.mp3 or.ogg format. This does not require root rights, but you will need a file manager with access to system folders (for example, MiXplorer or Solid Explorer).
Algorithm:
- Download the audio file (up to 2 seconds, the bitrate is not higher than 192 kbit / s).
- Rename it unlock.ogg (that’s the name that matters!).
- Copy the file to /sdcard/MIUI/sound/ If there is no sound folder, create it manually.
- Reboot the phone.
Download the file in MP3/OGG format
Cut to 1-2 seconds (for example, in Audacity)
Rename to unlock.ogg
Place it in /sdcard/MIUI/sound/
-->
⚠️ Note: On some models (POCO F4, Redmi K50) This method only works after resetting the sound settings in Settings. → Recovery and discharge → Resetting the audio settings. Also, the sound may not change if the file weighs more than 300 KB.
Method 3: Modify system files (root or ADB required)
For advanced users, there is a radical method of replacing the system file with the unlock sound. This works 100%, but requires either root rights or access through ADB. The danger of the method is that improper actions can lead to a reset or even a “brick” of the device.
Instructions for ADB (without root):
- Connect your phone to your PC and enable debugging via USB (Settings → About Phone → MIUI Version → 7 times tap the version).
- Download ADB Tools and open the command line in the folder with adb.exe.
- Follow commands in order: adb shell su mount -o rw, remount /system cp /sdcard/unlock.ogg /system/media/audio/ui/unlock.ogg chmod 644 /system/media/audio/ui/unlock.ogg reboot
🔹 Alternative: If you have root, use Root Explorer or FX File Manager to replace the file /system/media/audio/ui/unlock.ogg Don't forget to back up the original file!
What if the sound is completely lost after the replacement?

Frequent problems and solutions
Even after successful sound replacement, users are confronted with bugs, and here are the most common ways to fix them:
- 🔇 The sound hasn't changed: Check the file name (unlock.ogg - register is important!). Make sure the file is in the correct folder (/MIUI/sound/ or /system/media/audio/ui/). Reboot the phone.
- 🔊 The sound became quieter: MIUI 14 You have a volume limit on the system sounds. To remove it, you must perform it in the ADB: adb shell settings put global system_ui_sound_volume 100
- 🚫 Sound missing after update: Updates MIUI You can often reset custom sounds. Return the original file from the backup or repeat the replacement procedure.
💡
If you change unlock sounds often, create a folder. /sdcard/MIUI/sound_backup/ And you can back up your files, so you can quickly recover your favorite tune after you reset or update it.
How to return the standard unlock sound
If experiments with custom sounds are tired, you can return the original ding-don in two ways:
- Through reset: Go to Settings → Sounds and vibrations → Resetting the sound settings. This will bring all system sounds back to factory.
- Through ADB (if the reset didn’t work): Download the original firmware for your model, extract the unlock.ogg file from it (it lies in /system/media/audio/ui/) and replace your custom file with it.
⚠️ Note: On some models (Redmi) K40, POCO F3) Resetting sounds can also return the factory tune of alarm clocks and notifications. If you need to save them, write down the names of the sounds used before resetting.
