Personalization is one of the key factors that make using a Xiaomi, Redmi or POCO smartphone truly comfortable. The standard set of tunes pre-installed by developers often seems boring or too intrusive, prompting users to look for ways to replace it. Fortunately, the MIUI shell and the new HyperOS provide flexible tools for managing multimedia, allowing you to customize the device without having to hack the system.
Device owners often wonder if you can set your own track to lock the screen without getting root rights that can void the warranty. The answer is unequivocal: yes, it is quite possible to do this with standard system tools or with the help of proven third-party applications. In this article, we will discuss in detail all the current methods, from simple settings in the menu to more advanced options for power users.
Changing system sounds doesn’t require deep programming knowledge or sophisticated hardware; you’ll only need a smartphone itself, a stable internet connection to download files, and a few minutes of free time. Let’s look at the basic ways you can replace a standard peak or tune with any other audio file.
Using the Themes app to change sounds
The easiest and safest way to change the lock sound is to use the built-in content store. Themes is the central hub for customizing the interface in Xiaomi devices, where you can find not only wallpaper and fonts, but also entire packages of sounds created by designers and the community.
To get started, open the app and go to the bottom menu by selecting the Sounds tab. The system will offer you different categories: ringtones, notifications and, importantly for our task, lock sounds. You can listen to the available options right in the store. If the standard library seems poor, switch to the Profile tab and select Download Sounds to import your files from the device's memory.
💡
Before downloading your own tune, cut it to a length of 5-10 seconds so that the locking sound is not too long and annoying.
It's important to note that some themes change the lock sound automatically when they're activated. If you've installed a new theme, check if the system sound has changed. In the theme settings, you can often choose which components to use: wallpaper only, icons only, or sounds only, which allows you to combine the visual style of one theme with the audio accompaniment of another.
- 🎵 Open the Themes app on the main screen.
- 🔊 Go to the section Sounds in the lower interface menu.
- 📥 Click Download to import your file or select the finished option.
- ✅ Click Apply and Confirm the Installation for the Current Profile.
Configure through the system menu of sounds
The more traditional method that Android users are familiar with is deep in the system settings, and unlike the theme store, you work directly with the file system and assign files to specific events, which is preferable for those who want to use their own files. mp3-A file downloaded from the Internet or created independently.
To get to the menu, open Settings and find the Sounds and Vibrations section. Depending on the firmware version (MIUI 12, 13, 14 or HyperOS), the interface may vary slightly, but the logic remains the same. Find the "Lock Sound" or "System Sounds" section. This is where the audio file is tied to the action of the screen.
⚠️ Note: On some global firmware versions, the Lock Sound can be hidden or replaced by the Lock Sound On/Off switch, in which case the system uses standard system sound and cannot be changed through this menu without using themes.
If you have a file selection option on the menu, the system will open a standard file manager. Navigating packs in Xiaomi can be confusing, so pre-place the desired track in an easily accessible place, such as in the Music or Downloads folder. After selecting the file, the system automatically crops it or warns if the duration exceeds the permissible limit, usually 15-20 seconds.
Application of third-party applications for ringtones
When the built-in MIUI shell is not flexible enough, specialized applications from the Google Play Store come to the rescue, programs like Zedge, Ringtone Maker or MP3 Cutter allow you not only to find content, but also edit it, setting the exact starting and ending points for playback.
The application is the same for all Redmi Note, Xiaomi Mi and POCO F. Once installed, the app asks permission to access media files and audio settings. You select a song, crop the desired snippet and click the "Install as" button. Then select the sound type: "locking sound", "rington" or "notification".
However, it is worth considering the peculiarity of Android 10 and higher, which is based on modern versions of MIUI. Security system can block the direct installation of sounds by third-party applications, in which case the program will prompt you to manually complete the process through the system menu, where it automatically throws you with the already selected file.
- 📲 Download the application to work with ringtones from the Play Market.
- ✂️ Download or select an audiophile in the application library.
- 🎚️ Adjust the beginning and end of the fragment with sliders.
- ⚙️ Click Set and follow the instructions on the screen.

Comparison of methods of changing system sounds
The choice of how to replace sound often depends on the specific model of your device and the version of the operating system, and to make it easier for you to decide which method will be most effective in your case, we have prepared a comparison table that will help you assess the labor costs and functionality of each option.
| Method | Difficulty | Flexibility of setting | Risk of error |
|---|---|---|---|
| Tham's shop | Low. | Medium | Minimum |
| System menu | Low. | Tall. | Low. |
| Third-party annexes | Medium | Very high. | Medium. |
| Editing of the system | Tall. | Maximum | High-pitched |
As you can see from the table, for most users, the optimal balance between simplicity and result is the use of the system menu or theme store. Third-party applications give more freedom in editing, but require additional actions. Cardinal methods, such as replacing system files, we do not discuss in this guide, as they carry risks and are not required to solve the problem of changing the melody.
It’s also worth mentioning that on some HyperOS devices, sound logic has become even more integrated into the ecosystem, and that sounds can now sync with other Xiaomi smart home devices if they’re connected to a single account, opening up new possibilities for creating a single sound space around them.
The solution: Why the sound is not saved
Often users are faced with a situation where everything seems to be done correctly, but the lock sound does not change or is reset to standard after rebooting. Most often the problem lies in the file format or access rights. Android system is quite strict with audio formats for system events.
Make sure your file has an extension.mp3,.ogg or.wavFLAC or AAC The file may not be supported by the lock system player, and the file may not be protected. DRM-protection, which often happens with tracks downloaded from streaming services for offline listening.
⚠️ Note: If you are using dual-mode systems (e.g. First and Second Spaces), the sound needs to be adjusted separately for each profile.
Another reason could be the activated Do Not Disturb mode or the specific Sound profile settings, check if the system silent mode limit is worth the limit, and try clearing the Themes or Sounds app cache through the application management menu if the crashes are programmatic.

Features of work in HyperOS and new versions of MIUI
With the release of the HyperOS shell, Xiaomi has reworked many system sounds to make them softer and more enjoyable. However, the algorithms for working with user-generated content have remained similar, the main difference being the more aggressive optimization of power consumption, which can kill the background processes of ringtones applications.
If you use a third-party app to set sounds on a new firmware, be sure to add it to the battery exception list. Go to Settings → Apps → All Apps → Find your app, select Energy Saving and set the No Limits mode. This will prevent the installation process from accidentally ending.
The new versions also offer the ability to fine-tune sounds for different use cases, such as setting different lock sounds for different job profiles if the feature is supported by the region, and keeping an eye out for system updates as the functionality of the sound engine is constantly being improved by the company's engineers.
- 🔋 Add an app for sounds to power saving exclusion.
- 🔄 Update the Themes app to the latest version.
- 🛡️ Check the permissions in the Privacy Protection section.
- 📱 Make sure that the In-pocket mode does not block the speaker.
💡
The stability of sound settings in new versions of MIUI and HyperOS depends on the availability of current updates to system components and the correct permissions for applications.
