How to change the sound of the screen lock on Xiaomi Redmi Note 7: 5 proven ways

The screen lock sound on the Xiaomi Redmi Note 7 is a small but important interface element that can be both fun and annoying. The standard MIUI signal is not popular with everyone: some people find it too loud, some people feel monotonous, and some just want to personalize their smartphone. Fortunately, the manufacturer and third-party developers offer several ways to change this sound, from simple settings in the menu to install custom tunes.

In this article, we will discuss all the current methods of replacing the lock sound, including hidden MIUI functions, working with system files (for advanced users), and using third-party applications. We will focus on the nuances associated with the Redmi Note 7 — its version of Android, firmware limitations and typical errors when changing sounds. If you want to make your phone unique or just get rid of the annoying “click” — read on.

Why does the standard block sound not work?

The audio accompaniment of the screen lock in MIUI has two key functions: it signals successful locking and adds tactile feedback, but factory sounds are often criticized for:

• 🔊 Too high volume – especially noticeable in quiet rooms or at night.
• 🎵 Limited choice – in standard firmware available everything 2-3 variant.
• 📱 Style mismatch – sound may be dissonant with wallpaper, theme, or overall interface design.
• 🔄 Lack of flexibility – it is impossible to assign different sounds to lock and unlock.

Complicating matters with the Redmi Note 7, the model was released in 2019 with a MIUI 10 based on Android 9 Pie, and subsequent updates (up to MIUI 12.5) did not always remain stable when changing system sounds. For example, after upgrading to Android 10, many users complained about the factory reset of custom sounds.

Method 1: Replace sound with standard MIUI settings

The easiest and safest method is to use built-in MIUI options. It does not require root rights or third-party applications, but has restrictions on the choice of sounds.

Instructions:

1. Open the Settings. → Sound and vibration.
2. Go to the System Sounds section.
3. Select the screen lock sound (on some versions of MIUI it may be called lock/unlock sound).
4. From the list, select the sound you like. Standard options usually include: 🔔 Default (standard) 🔕 None (no sound) 🎶 MIUI Tune (brand tune)

Note: On the Redmi Note 7 with MIUI 11+, the sound list may be different from older versions. If you don’t have the right option, try updating your firmware via Settings → About Phone → System Update.

⚠️ Note: On some custom firmware (e.g. Xiaomi.eu or Pixel Experience), the locking sound may not be on the menu.

Method 2: Using MIUI themes to change sounds

The themes in MIUI are not only wallpaper and icons, but also complex design packages that can include custom sounds, a method suitable for those who want to change not only the locking sound, but also other system signals.

How it works:

1. Open the Themes app (icon with brush).
2. In the search bar, enter the query for sounds or sound.
3. Choose your favorite theme marked "Includes sounds" (usually this is indicated in the description).
4. Click Apply and confirm installation.

Popular themes with sounds for the Redmi Note 7:

Once you apply the theme, the lock sound will change automatically. To return the standard version, reset the theme to the factory in the Themes app settings.

💡

If the sound hasn't changed after you set the theme, restart the phone. Sometimes MIUI only applies the audio settings after the reboot.

Method 3: Manually replace audio files (for advanced users)

This method requires access to system files and is suitable for those who are ready to work with Root or ADB. It allows you to install any sound in.ogg or.mp3 format, but there are risks.

Step-by-step:

1. Get Root rights (for example, via Magisk) or connect to your phone via ADB.
2. Download your favorite sound (duration no more than 2 seconds, bitrate up to 192 kbit / s) and convert it to.ogg using an online converter.
3. Rename the file to lock.ogg (for lock) or unlock.ogg (for unlock).
4. Copy the file to /system/media/audio/ui/ and replace the existing file (create a backup of the original!).
5. Change the file permission to 644 (r-w-r--r---).
6. Reboot the phone.

Instructions for Zedge:

1. Install the app from Google Play.
2. In the search, enter lock sound.
3. Select the sound you like and click Set as → Lock Screen Sound.
4. Confirm the replacement in the system dialogue.

Important: Some apps (like Sound Picker) may not work on MIUI 12+ due to the limitations of Android 10, in which case try to roll back to an older firmware version or use ADB to force audio assignment.

💡

Apps like Zedge only change the sound for the current user, and once you reset or update MIUI, the sound will return to the standard.

Method 5: Turn off the lock sound completely

If you don't like the sound of locking at all, you can turn it off completely, which is true for those who use the phone in quiet places (library, bedroom) or prefer tactile feedback.

How to turn it off:

1. Go to Settings → Sound and vibration → System sounds.
2. Select Screen Lock Sound.
3. Set the value of None (no sound).

The alternative is to turn off all system sounds:

• 🔇 Turn on the mode Do not disturb (Settings) → Don't disturb).
• 📴 Set Vibration When Touching in Settings → Additionally. → Special facilities.

⚠️ Attention: On the Redmi Note 7 with MIUI 12.5 Disabling the lock sound through None may not work due to a firmware bug, in which case use the Sound Picker app and assign an empty audio file (you can create in Audacity).
