How to Change the Lock Sound on Xiaomi: The Complete Guide

Personalizing the interface of a smartphone is one of the most enjoyable aspects of owning an Android device, especially when it comes to Xiaomi products. Users often seek to replace standard system sounds with more pleasant or unique tunes to reflect their individuality. However, in the shell of MIUI or the new HyperOS, the process of replacing the screen lock sound (when you swipe your finger to unlock) may seem unobvious due to the deep integration of system files and access rights restrictions.

Unlike setting a ringtone to an incoming call, where you just need to select a file in your audio settings, changing the audio file when you unlock requires understanding the structure of the menu or using third-party tools. Standard themes available in the store often offer ready-made packages, but they may not match the taste preferences of the owner or contain advertising. That is why it is important to understand the mechanics of the sound subsystem Redmi and POCO to have full control over the audio of your gadget.

In this article, we will discuss in detail all the available ways to change the tune, from the regular tools of the system to advanced methods for advanced users. You will learn how to circumvent restrictions, where to put files and what to do if the standard functionality does not give the desired result. Proper audio tuning will not only improve the user experience, but also make the use of the device more comfortable.

Standard methods of setting up through the system menu

The easiest and safest way to change the soundtrack when unlocking is to use the operating system's built-in settings. Depending on the shell version (MIUI 12, 13, 14 or HyperOS), the location of the items may vary slightly, but the logic remains the same. The system offers a choice of pre-installed set of tunes that are optimized for your device's speakers and not distorted when playing.

To access these settings, you need to go to the main menu and find the Settings section. The path usually goes through the Sound and Vibration section, where all the audio output parameters are concentrated. Here you will find the Lock Sound option (sometimes called Lock Screen Sound or part of the common system sounds).

• 🎵 The list of options: the system offers about 10-15 Standard melodies of different duration and style.
• 🔊 Pre-Earsay: Each track can be listened to before installation by clicking on the speaker icon.
• 🔄 Resetting: You can return standard sound at any time by selecting the default option».
• ⚙️ Integration with themes: Some sounds can change automatically when you change the global theme of the design.

⚠️ Note: On some global firmware versions, the "locking sound" item may be hidden or combined with "System sounds."If you don't find a separate switch, try changing the theme, as new themes often bring their own locking sounds.

It is important to note that standard methods do not allow the use of arbitrary MP3-Android security system and Xiaomi policy restrict applications from accessing system partitions where interface sounds are stored. If you want your favorite song, you will need to use other methods, which will be discussed below.

Using the Themes app to change audio

Xiaomi’s official Themes app is a powerful customization tool that is often underrated, allowing you to change not only icons and wallpaper, but also system sounds, including audio files when you unlock the screen. The theme store contains thousands of options created by designers and the user community.

To find the right option, open the Themes app on the home screen or in the Tools folder. In the search bar, type in a query like "Sound" or "Lock sound." In search results, pay attention to the preview: often authors indicate that the theme includes new lock sounds. Once the theme is loaded, you do not need to apply it fully, you can select only the audio profile.

When you use a theme, the system can request permission to change the system settings. Confirm the action and the sound changes instantly. If you like only the sound and the rest of the theme design doesn't work, you can immediately return the old theme after you use the sound profile - in most cases, the lock sound will remain changed, although in newer versions of HyperOS this behavior can be changed to more isolation of components.

• 🎨 A huge selection: thousands of free themes with unique sound effects.
• 📥 Automatic installation: no need to search and copy files manually.
• 🗑️ Easy removal: Theme can be deleted at any time through the Profile menu».
• 🌍 Regional restrictions: In some regions, the theme store may operate with restrictions.

Using official themes is the most stable way to ensure compatibility: third-party files can cause conflicts or play incorrectly at different volume levels, and themes are often updated by developers, fixing bugs and improving audio quality.

Setting your melody as a locking sound

For those who want complete uniqueness, it is possible to install their own audio file. However, unlike ringtones, MIUI does not always provide a direct "Select from Files" button for the lock sound.

First, prepare an audiophile. It should be.mp3 or.ogg, last no more than 15-20 seconds (optimum for short sound) and have an acceptable quality. Copy the file into the phone's internal memory. Then open the standard File Explorer and find the MIUI folder at the root of the internal memory, and you're interested in the sound directory inside it, and the lockscreen folder in it.

If the lockscreen folder is not available, create it manually. Put your file in this directory. After that, restart your smartphone. In some cases, the system will automatically pick up a new file. If that doesn't happen, go back to the sound settings and try to select a theme with a similar name or reset the sound settings, after which your file can appear in the list of available.

Keep in mind that when you update your system or change theme manually, added files can be deleted or overwritten, so always store original tunes in the cloud or on your computer to quickly restore personalization.

Application of third-party launchers and applications

If system constraints are too tight, Google Play apps come to the rescue. There are specialized utilities that intercept the unlock event and play back the selected sound. One popular solution is the Lock Screen & Notifications app, or analogues, which create its own layer on top of a standard lock screen.

These applications offer advanced functionality: customization of transparency, watch widgets, weather and, of course, full control of sound. You can assign any file from memory, adjust the volume separately for lock sound, and even set different sounds for different profiles (for example, quiet sound at night).

💡

Use apps to create short clips of tunes so that the lock sound isn't too intrusive. Long intros can be annoying when you unlock your phone frequently.

However, this method has its drawbacks: a third-party lock screen consumes more battery power, as the process constantly monitors the status of proximity sensors and gyroscopes. In addition, on modern versions of Android, such applications can work unstable due to Xiaomi’s aggressive energy saving policy.

• 🚀 Advanced features: the ability to put video wallpaper and complex animations.
• 🔋 Battery consumption: an additional layer of the interface consumes energy.
• ⚙️ Difficulty of setting up: multiple permissions are required.
• 🛡️ Security: Trust only trusted developers.

When installing such software, be sure to check reviews and the date of the last update. the application must be adapted for Android 12/13/14, otherwise it may simply not start or fly out when trying to unlock the device.

Problems with locking sound on MIUI and HyperOS

Xiaomi users often face a situation where the lock sound is not played at all or is played with a delay.This may be due to the optimization of the system, which “kills” background processes to save energy.

First of all, check whether Do Not Disturb or No Sound is on, and in these modes, system sounds, including locking, are often forced to turn off, and it's also worth looking at the special features settings: Mono-audio or balance settings can affect the perception of sound.

⚠️ Warning: If the sound is gone after a firmware update, it may be a bug of a particular version. Check the user forums of your model. Often, cleaning the cache of the Themes and Sound app through the Apps menu helps» → «All applications».

Another common problem is the conflict of topics: If you have a theme that is not fully compatible with your version of MIUI, the sound may disappear, the solution is to reset the theme to the standard ("Classic" or "Default") and check for the sound, and if the sound appears after that, then the problem was in a third-party theme.

Advanced customization through ADB (for experienced)

For users who are not afraid of the command line, there is a method of replacing system files through ADB (Android Debug Bridge), which allows you to replace the standard system file of the lock sound directly, without using third-party applications, which gives a 100% guarantee that the sound will work forever, as it becomes part of the system.

For this you will need a computer, USB-cable and installed drivers ADB. On the phone, you need to activate the developer mode (7 times click on the build number in "About Phone") and turn on "Debugging by phone". USB». Connecting the device to the PC, execute the command to obtain the rights shell.

adb shell


su




mount -o rw,remount /system




cp /sdcard/my_lock_sound.ogg /system/media/audio/ui/lock.ogg

This method requires extreme caution. Incorrect actions can lead to software failure.
