How to remove the sound of unlocking the screen on Xiaomi Redmi Note 10 Pro: all working methods

The sound of unlocking the screen on the Xiaomi Redmi Note 10 Pro can be annoying — especially at night when you check notifications in silence, or in the office where each click attracts unnecessary attention. The manufacturer by default turns on this sound signal in the MIUI firmware, but disabling it is not as easy as it seems: standard settings often hide the option or do not contain it at all. In this article, we will analyze 5 proven methods, from basic to advanced, including working with ADB and hidden menus.

Complicating the problem is that different versions of MIUI (12, 13, 14+) may have different paths to audio settings, and some methods stop working after updates. We tested all the ways on the Redmi Note 10 Pro with current firmware and highlighted the ones that are guaranteed to work. If you've already tried to turn off sound through Settings → Sounds and didn't find the right switch there, don't worry, there will be more powerful solutions next.

Why is the unlock sound not turned off through standard settings?

In most Xiaomi smartphones, the option to turn off the unlock sound is hidden or not at all. MIUI, where some system sounds are tied to security (e.g., fingerprint unlock confirmation or PIN-Here are the key reasons:

• 🔄 Version. MIUI: In the firmware older MIUI 12.5 The option could be available in the Sound and Vibration menu, but it was removed in the new versions.
• 🔒 Security Policy: The unlock sound is considered additional confirmation of the successful password entry (similar to vibration).
• 📱 Regional firmware: Global (Global) and Chinese (China) versions MIUI The set of settings may differ.
• 🛠️ Xiaomi sometimes blocks system sounds change for stability.

If you haven’t found the switch in Settings → Sounds and Vibrations → System sounds, don’t get upset – that’s OK. Next we’ll look at workarounds, including editing system files and using ADB.

Method 1: Disable via the Sound and Vibration menu (not working on all firmware)

Let's start with the simplest method that can work on older versions of MIUI or regional firmware.

1. Open Settings (the gear icon on the main screen).
2. Go to the section Sound and vibration.
3. Slip on System Sounds (or Other Sounds in some versions).
4. Look for the Unlock Sound or Lock/Unlock Sound option.
5. Move the slider to the off position.

If there's no such item, your firmware doesn't support it, so move on to the next one.

⚠️ Attention: On some firmware MIUI 13/14 Unlocking sound can only appear after resetting to factory settings, but it's a radical method, and we don't recommend using it just to turn off the sound.

Method 2: Use of Do Not Disturb (Backway)

If the system sound doesn't turn off directly, you can mask it with Do Not Disturb mode, which doesn't completely remove the sound, but makes it inaudible in most situations:

1. Open Settings → Sounds and vibrations → Do not disturb.
2. Activate the mode by selecting Schedule or Manual.
3. In the mode settings, select Only alarm clocks or No sounds.
4. Turn on the option to always show notifications so you don’t miss important messages.

The downside is that when you activate Do Not Disturb, all notifications, including calls, will be disabled, but you can configure exceptions for selected contacts in the Allow Exclusions menu.

Method 3: Disabling audio via ADB (for advanced users)

If the standard methods didn't work, the most reliable way is to use Android Debug Bridge (ADB), a debugging tool that lets you change system settings without rooting.

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📱 Included Developer Options and Debugging by USB phone-on.
• 🔌 USB-cable (preferably original).

Steps:

1. Connect the Redmi Note 10 Pro to your computer and allow debugging over USB.
2. Open the command prompt (cmd on Windows) and type:

adb shell settings put global lock_screen_sounds_enabled 0

1. Reboot the phone.

If the command doesn’t work, try an alternative for the new MIUI versions:

adb shell settings put system lockscreen_sounds_enabled 0

Once executed, the unlock sound should disappear. If not, check if the settings have reset after the reboot (sometimes you need to repeat the command).

💡

Before using ADB, make sure that the developer's OEM unlock option is enabled on your phone, and without it, some commands may not execute.

Method 4: Editing system files (requires root rights)

This method is only suitable for users with an unlocked bootloader and Magisk installed (or other root-retrieval method), and involves editing the system/media/audio/ui/Lock.ogg file, which is responsible for unlocking the sound.

Instructions:

1. Install a file manager with root support (such as Root Explorer or FX File Explorer).
2. Go to /system/media/audio/ui/.
3. Find the Lock.ogg file (or Unlock.ogg in some firmware).
4. Rename it to Lock.ogg.bak or delete it (pre-return it!).
5. Reboot the phone.

⚠️ Attention: Deleting or editing system files can cause system crashes or update problems. Always backup before changes. If the phone doesn't turn on after rebooting, restore the file from backup via TWRP.

Alternatively, you can replace Lock.ogg with an empty audio file (you can create it in any audio editor), which will preserve the integrity of the system, but remove the sound.

Method 5: Install custom firmware (radical solution)

If none of the methods worked, the last option is to switch to custom firmware (for example, LineageOS, Pixel Experience or Xiaomi.eu), in which unlock sounds are usually configured flexibly, and unnecessary system restrictions are removed.

Cons of the method:

• ⚠️ Loss of warranty (if the phone is under warranty).
• ⚠️ Risk of "bricking" with incorrect firmware.
• ⚠️ Possible bugs (not all functions can work correctly).

If you decide to do this, follow the official firmware instructions for the Redmi Note 10 Pro (codename sweet).

• 📱 Unlock the bootloader through the Mi Unlock Tool.
• 🔄 Install. TWRP Recovery.
• 💾 Make a full backup through TWRP.

💡

Custom firmware gives you complete control over system sounds, but requires technical skills. If you're a beginner, you'd better focus on the ADB method or Do Not Disturb mode.

Frequent problems and their solutions

Even after one of the methods is used, the unlock sound can continue to play, and let's look at the typical causes and ways to eliminate them:

If you’re using MIUI 14 and the unlock sound is associated with Always-on Display (AOD), try turning off AOD in the screen settings – sometimes this removes unnecessary sounds.
