How to change the lock sound on Xiaomi Redmi Note 8T: all working ways

The Xiaomi Redmi Note 8T is one of the most popular smartphones in the budget segment, but even it has customization limitations. For example, many users want to change the standard screen lock sound, which eventually becomes annoying or just annoying. Unfortunately, MIUI does not provide a direct opportunity to change this sound through the settings, as it is done in some other firmware. However, there are several workarounds – from using hidden functions to installing third-party applications.

In this article, we will discuss all the current ways to replace the lock sound with the Redmi Note 8T, including methods for users without root rights and for those who are ready for a deeper setup, and discuss why some methods may not work on the latest versions of MIUI and how to avoid it. If you are tired of the standard “click” when blocking or want to set the tune to your taste, read on.

Why is there no standard option in MIUI to replace the lock sound?

Unlike some other Android firmware (such as Samsung One UI or OxygenOS), where lock sounds can be changed through the Sounds and Vibrations menu, MIUI deliberately limits this feature.

• 🔒 Uniform user experience. Xiaomi aims for a minimalist interface where most sounds are unified across all devices in the series.
• 🛡️ Security and stability: Changing system sounds can lead to conflicts, especially if the user installs files with the wrong format or bitrate.
• 📱 Optimizing for budget devices on smartphones like the Redmi Note 8T Limited resources, and excessive customization can affect productivity.

However, these limitations are not absolute. There are legal ways to get around them, from using applications to editing system files (the latter requires root access).

⚠️ Attention: On devices with MIUI 12.5 and later, some methods (e.g., File Manager replacement) may not work due to tightening security policies. → The phone. → Version. MIUI.

Method 1: Use the Zedge application (without root)

The easiest and safest way is to install a third-party app to replace sounds. Zedge is one of the most popular solutions that allows you to download and set custom tunes, notifications and lock sounds. Here's how to do it:

1. Download Zedge from Google Play.
2. Open the app and go to Lock Sounds.
3. Select the sound you like and click Set.
4. In the window that appears, select Lock Sound.

The app will automatically apply the selected sound, but there’s a caveat: on some versions of MIUI, Zedge can set the sound only for notifications, not to block.In this case, try alternative apps like Ringtone Maker or Notification Sounds.

Method 2: Manually replace with File Manager (requires root or ADB)

If you're ready for more complex manipulations, you can manually replace the system lock sound.

• 🔧 Root access (e.g. via Magisk) or
• 🖥️ ADB-Access (without root, but with a PC connection).

Instructions for users with root:

1. Download any sound file in.ogg format (recommended bitrate - 128 kbit / s, duration up to 3 seconds).
2. Rename it to lock.ogg (for lock) or unlock.ogg (for unlock).
3. With Root Explorer or Solid Explorer, go to /system/media/audio/ui/
4. Back up your original files (for example, move them to another folder).
5. Insert your files and set them 644 (r-w r--- r----).
6. Reset the device.

For users without root, but with ADB:

1. Connect your phone to your PC and activate USB Debugging in Settings → About Phone → MIUI Version (click 7 times on MIUI Version, then go back to Additional Settings → For Developers).
2. Open the command prompt on your PC and execute: adb pull /system/media/audio/ui/lock.ogg (this will copy the original file to your PC for backup).
3. Replace lock.ogg with your file and send back: adb push your file.ogg /system/media/audio/ui/lock.ogg
4. Install the correct permissions: adb shell chmod 644 /system/media/audio/ui/lock.ogg

⚠️ Attention: MIUI 13+ system-part /system It can be protected from recording even through ADB. In this case, without root, you can not get around the restriction.mp3 — They may not be reproduced or cause delays.

Method 3: Use MIUI themes (limited selection)

MIUI has a built-in theme system that allows you to change not only wallpaper and icons, but also some sounds. However, the choice of blocking sounds in the themes is extremely limited, and not all themes support them.

1. Open the Themes app.
2. Go to the Sounds section or find a topic marked “Includes sounds”.
3. Apply your favorite theme – the locking sound will change along with other elements.

Cons of this method:

• ❌ Very few themes with unique locking sounds.
• ❌ The sound changes only within the selected theme – you can not install it separately.
• ❌ After resetting themes or updating MIUI The sound can return to standard.

However, if you don’t need a unique sound, but just want a little variety, this method is the fastest and does not require additional applications.

• 📱 Clear the cache in Settings → Annexes → Sound Assistant → Warehouse.
• 🔧 Enable Developer Mode and Disable Optimization for this Application.

Table: Comparison of methods of replacing the lock sound on the Redmi Note 8T

As you can see from the table, the safest and most versatile method is to use Zedge. Manual replacement via root or ADB is suitable for power users, but is fraught with problems on new versions of MIUI. Themes and Sound Assistant are compromise options with limited functionality.

On the Redmi Note 8T with MIUI 13/14, the most reliable way is with third-party apps like Zedge, which manually replace system files is unstable and requires technical skills.

Frequent problems and their solutions

When replacing the lock sound, users often encounter common errors, and let's look at the most common ones and how to fix them:

• 🔊 The sound didn't change after the file was replaced: Check that the file has the correct name (lock.ogg) and format. Also make sure it's in the correct folder (/system/media/audio/ui/ or /vendor/media/audio/ui/).
• 📱 After updating MIUI sound reset: Firmware updates often overwrite system files.To avoid this, back up your sound and restore it after each update.
• 🚫 App can't change lock sound: On new versions MIUI Some applications (such as Sound Assistant) lose access to system settings. Try rolling back the app version or using alternatives.
• 🔇 The locking sound is completely gone: If the sound disappeared after manipulation, check the volume settings in Settings → Sounds and vibrations → Media volume. Also make sure the file is not corrupted.

⚠️ Note: If you use root to replace system files, never delete the original sounds without backing up.In the event of an error, this can lead to endless bootloop, especially if the file is in the wrong format or resolution.

💡

If you experiment with sounds often, create a folder. backup_audio You can go to the root of the repository and copy the original files before you replace them, and that saves you time when you roll back the changes.
