How to change the sound of the screen lock on Xiaomi Redmi: a full guide

Smartphone personalization is not just a way to stand out, it’s also an opportunity to make interaction with the device more comfortable. The locking sound is one of those system signals that we hear dozens of times a day, and the standard melody can get boring quickly. Owners of Xiaomi and Redmi devices often face the desire to replace the standard “click” or music snippet with something more pleasant or, conversely, more noticeable.

The procedure for replacing system audio files on the shell of MIUI or the new HyperOS has its own features that differ from pure Android. Unlike call ringtones, system sounds of the interface are sometimes hidden in deep menus or require the use of file managers to activate user tracks. However, once you understand the structure of the settings, you will have complete control over the audio of your gadget.

In this article, we will discuss in detail all the available ways to change the lock sound. We will look at the standard system tools, working with the file system and the nuances that can occur when using custom tunes. It is important to know that on some global versions of firmware, the path to settings may be slightly different from the Chinese versions.

Standard sound design settings in MIUI

The first and most obvious way to change the sound is to use the built-in functionality of the system. Xiaomi developers have provided a basic set of options for setting up audio notifications. To access them, you need to go to the main settings menu of your device. Usually the path is: Settings → Sound and vibration.

In the menu that opens, you'll find Additional Sounds or Notification Sounds, depending on the shell version. This is where you can find settings for system events like locking the screen, charging the battery or pressing the keyboard. Standard tunes may be limited, but they're optimized for power consumption and clear perception.

If you don't see a separate "Screen Lock" item, try logging in to the Notification Sounds section. In some versions of MIUI, the lock sound is linked to the system's general notification profile. By clicking on this item, you'll open a list of available tracks where you can select your favorite option from the preinstalled ones.

• 🎵 Open the Settings menu on the desktop.
• 🔊 Go to the section Sound and vibration.
• 🔍 Find Additional Sounds or Screen Lock Sound.
• ✅ Select the desired tune from the list.

💡

Standard settings allow you to quickly choose a tune, but the choice is often limited to the system set.

It’s worth noting that on some models, such as the Redmi Note or Xiaomi Mi series, the interface can offer an extended store to those where additional audio packages are available, a convenient way to diversify the audio range without having to search for files on the Internet.

Using the "Themes" application to expand the library

Themes app on Xiaomi smartphones is a powerful customization tool that is often overlooked when searching for system sounds, and allows you to download not only wallpaper and icons, but also entire audio packages that include unique lock, unlock and notification sounds.

To find the content you want, open the Topics app and go to the Sounds section or search the "Lock sound" or "Lock Sound" section, and you'll be surprised how many options users and designers have, and when you download the package, the system will suggest that you use the sounds, and they will automatically replace the standard ones.

⚠️ Warning: When installing themes from third-party sources or even from an official store, carefully check permissions. Some themes may try to access contacts or location that is not required to change the tune.

The thing about themes is that you can only use the audio package without changing the visual part of the interface. When you activate the theme, select the option "Apply only sounds" or similar if it is available in the preview menu, which will preserve your desktop look, but update the audio.

In addition, the Themes app often features seasonal collections or sounds from popular games and movies, a great way to add personality to the device using the legal and secure resources of the Xiaomi platform.

Installing your own lock sound through file manager

The most flexible method to install any audio file as a signal is manual downloading through the file manager, so you'll need an MP3 or M4R file that you want to use, download it from the Internet or copy it from your computer.

Once the file is stored in the device's memory, the algorithm is as follows: Open the standard Explorer application or any other file manager. Find the downloaded file, click on it and hold your finger to call the context menu. Select Use as sound or Assign as → Lock Sound.

If you don't have a direct command, you can go another way. Copy your audio file into the system sound folder. To do that, go to Internal Memory → MIUI → sound. If there's no sound folder, create it. Put your file there. Then it should appear in the list of standard tunes in the audio settings.

It is important to remember the length of the track. The lock sound should not be too long, otherwise it will be cut off or interfere with quick access to the device. The optimal duration is from 1 to 5 seconds. Long compositions are better used as an incoming ringtone.

Set up sound and vibration parameters

In addition to selecting the melody itself, MIUI allows you to fine-tune the behavior of the sound. In the Settings → Sound and vibration section, you can adjust not only the volume, but also the presence of vibration when you lock, and this is especially true in situations where the phone is in your pocket or bag.

Notice the locking vibration switch. If it's active, the phone will vibrate every time the screen goes out. This can be useful for confirming the action, but in a quiet environment or at night it can be annoying. Turn off this feature if you only need an acoustic signal.

Also worth mentioning is Do Not Disturb mode. If it is activated, the screen lock sound may not play back to prevent the user from disturbing the rest of the user.

Solving problems with lack of sound

Sometimes users are faced with a situation where everything seems to be set up correctly, but the sound is not played when blocked.The first reason is often the installed silent mode or too low volume of system sounds. Check the volume slider by pressing the adjustment buttons and selecting the settings for the System.

The second common problem is the conflict of third-party launchers or memory cleanup applications. Aggressive optimizers can kill the system processes that control the audio engine of the interface. Try adding system services to the power saving exceptions.

⚠️ Warning: If the theme is lost after installing the custom theme, try resetting the theme settings to standard. Incomplete compatibility of the theme with your version of Android can cause glitches in the audio.

Also check if Mono Sound or other special features are enabled in Advanced Settings → Special Features. Sometimes these features reassign audio streams, which can cause system sounds to disappear or distort.

In rare cases, a simple restart of the device helps, which clears the temporary cache of audio services and returns them to working condition, and if nothing helps, it may be the hardware part of the speaker that is the problem, but this is extremely rare for system signals.
