How to change the sound of locking the screen Xiaomi: a step-by-step guide

Owners of Xiaomi, Redmi and POCO smartphones often strive to personalize their device by making it unique. One of the most noticeable interface elements that users encounter dozens of times a day is the lock screen. The standard melodic ringing preinstalled by MIUI or the new HyperOS can get bored or simply not match the mood of the gadget owner.

Fortunately, the developers have flexible options for customizing audio, so you can replace the standard system tone with any song from your library, download a special ringtone, or even use the sound effect from a video, a process that does not require superuser rights (Root) and takes only a few minutes, if you know exactly where the desired settings are hidden in the confusing menu of modern shells.

In this article, we will discuss in detail all available ways to replace the lock sound. We will look at standard methods through system settings, working with files through the Manager and solving common problems when the selected track is not played, and pay attention to the differences in the interface of different versions of firmware, so that the instruction is relevant for both old models and new products from 2026-2026.

Audio file preparation and format requirements

Before you go directly to the settings of the smartphone, you need to prepare the sound source itself. Android system and the shell MIUI have certain requirements for the format and length of the audio file, ignoring which can lead to the fact that the sound will simply not apply or will be played incorrectly.

The optimal format for ringtones is MP3 with a bit rate of 128 kbit / s or higher. OGG and WAV formats are also supported, but MP3 remains the most versatile and lightweight option. The sound fragment should not exceed 30 seconds in length, although the system may allow you to install a longer file, but this is not advisable in terms of battery consumption and performance.

Use special editing apps to crop tracks to highlight exactly the snippet of a song you like without loading extra seconds of silence or introductory.

It is important to place the file in the device's memory correctly. In order for the system to automatically see your track in the list of available, it is best to place it in the root folder of memory or in a special directory of Ringtones. If you download audio from the Internet, the browser can by default save it to the Download folder, which sometimes hides the file from the system menu of selecting tunes.

⚠️ Note: Do not use files with protection DRM (These tracks have limitations on playback outside of the player application and cannot be installed as a system lock sound.

Standard method of replacement through sound settings

The easiest and most reliable method of changing tone is to use the built-in settings menu, which may vary slightly depending on the version of the shell, but the logic remains the same for all Xiaomi devices. You do not need third-party applications, enough standard functionality.

To start, open the Settings app and find the audio section. In the newer versions of HyperOS and MIUI 14, this item is often called Sound and Vibration, whereas in older versions it could be inside the Sounds section. Click on Lock Sound or Lock Screen.

Once you enter the selection menu, you will see a list of preset tunes. To put your track, scroll the list to the top or bottom (depending on the OS version) and select "Select music on the device" or "+" icon. The file manager or system player will open, where you need to find the previously downloaded audio file.

Once you select a track, the system will suggest listening to it and confirming the action. Press OK or Apply. Now, every time you turn on the screen, your smartphone will play the selected fragment. If there is no sound, check if the phone is in silent mode, since some versions of MIUI tie the lock volume to the overall level of the media or call.

Using the theme of design to change the sound

A unique feature of the Xiaomi ecosystem is the Themes app, which allows you to change not only icons and wallpaper, but also system sounds, including the lock tone, and it is a great way to get professionally made audio design that perfectly matches the visual style of the interface.

Go to the Themes app. At the bottom of the screen, look for the Profile or Mine tab, and then go to the Ringtones or Sounds section, and there's a huge catalog of audio files, sorted by genre, popularity and novelty, many of which are free.

  • 🎡 Categories: Pop, Rock, Electronics, Cinema, Nature.
  • πŸ“₯ Download: Click on the track to listen and the download button to save.
  • βš™οΈ Application: After downloading, click "Apply" to set the sound to lock or call.

The advantage of this method is that you get an optimized file that is guaranteed to work correctly, and the themes often contain entire packages of sounds for different system events (notifications, keyboard, lock), which allows you to create a single audio atmosphere.

In some regions, the Themes app may be limited. Try changing the region in the settings (India, Indonesia) to access the full ringtone catalog.

Setup through File Manager (for advanced users)

If the standard menu doesn’t see your file or you prefer to work with the file system directly, you can use the built-in File Manager, which is especially useful when you need to quickly apply sound downloaded from a messenger or browser that is not automatically determined.

Open the Explorer app and go to the folder where your audio file is located (usually Download or Music). Click on the file and hold your finger to highlight it. In the bottom menu that appears, select "More" (three dots) and find the "Install as" or "Appoint ringtone" option.

The system will ask you what kind of event you want to use that sound for, and you can select Lock Sound, which is a good way of forcibly registering a file in the system as a valid ringtone, adding it to the overall list of available tunes.

Reproduction problems and their solution

Sometimes users are faced with a situation where everything seems to be done correctly, but the sound when blocked does not sound. Most often the problem lies in the conflict of volume profiles. In Android, there are separate sliders for media, call, alarm and notifications. The lock sound can be tied to any of them depending on the version of the firmware.

Check volume settings. Press volume buttons and expand the menu (clicking on gear or down arrow). Make sure the Media or System slider is not kept to a minimum. Also check if Do Not Disturb or Silent Mode is activated, which can block system sounds.

⚠️ Note: Some Redmi Note models and POCO The lock sound may not work if the β€œSilence in your pocket” function is enabled or the proximity sensor is closed with a cover when the screen is turned on.

Another common reason is incompatibility of bitrate or file sampling rate if the track is written in high resolution (for example, FLAC or WAV 24-bit), The system may not be able to decode it instantly when the screen is turned on. MP3 128-320 kbps.

Third-party customization applications

If built-in capabilities aren't enough, Google Play offers a plethora of audio management apps, popular utilities like Zedge or Super Sound provide access to millions of tracks and have built-in editors.

However, it is worth remembering security. Rington replacement applications often require wide permissions to access the file system and microphone. Use only proven high-rated programs. Once the ringtone is installed, such an application can often be deleted, since the file is already saved in the system.

When using third-party software, carefully monitor the ads that may pop up in the process. Some "free" versions of programs impose the installation of additional software. The best option is to download the track through the browser and install it with standard MIUI tools.

The most stable result is the use of standard system tools or official store Tem, as they guarantee compatibility with the specific hardware of your smartphone.

FAQ: Frequently Asked Questions

Can I set my voice or recording from a voice recorder?
Yes, it's possible. Record the sound through the recorder, save the file in MP3 format (some recorders save to M4A or AAC, which is also supported), and place it in the Ringtones folder. Then select it through the audio settings as a regular file.
Why is the sound of a locking down quieter than the sound of a bell?
This is a system restriction designed not to scare the user with a sharp sound every time he calls the phone, the volume of system sounds (clicks, locks) is adjusted separately from the volume of the call and often has a program limit.
Will the lock sound reset after the system update?
In most cases, when updating MIUI or HyperOS, the user's audio settings are saved. However, if the update is major (for example, switching from Android 13 to 14), the settings can be reset to factory, and the procedure will have to be repeated.
How to remove the block sound completely?
In standard Xiaomi settings, there is no β€œNo Sound” option to lock the screen. The only way is to set a very quiet audio stub (file with silence lasting 1-2 seconds) or turn on vibration / silent mode.
Does this work for POCO and Redmi?
Yes, since all brands (Xiaomi, Redmi, POCO, Black Shark) use a single MIUI or HyperOS software platform, the instruction is universal for all devices of the company, regardless of the brand name on the case.
