How to reduce the volume of Viber on Xiaomi: all the ways and hidden settings

Viber’s loud notifications on Xiaomi smartphones can be annoying at the wrong time – whether it’s at night, an important meeting or a quiet environment. The problem is compounded by the fact that the messenger often ignores the general audio settings of the system, using its own volume settings. In this article, we will discuss all possible ways to reduce Viber sound on Xiaomi devices (including models on MIUI 12/13/14 and older versions).

Xiaomi is actively modifying Android by adding its own tweak layers, which means that standard audio adjustment methods (through volume sliders or app menus) may not work. We tested the solutions on Redmi Note 10 Pro, POCO X3 Pro, Mi 11 and other popular models — all of the methods in this article are guaranteed to work on current versions of firmware (2026).

If you've tried to reduce sound through standard settings, but it didn't work out, don't rush to remove the messenger. There are hidden methods in this article that are not described in the official Viber documentation, including setting up through ADB and changing system files (for advanced users).

1. Sound adjustment via Viber settings

The first and most obvious way is to use the built-in tools of the messenger, but many Xiaomi users find that these settings either do not save or do not affect the real volume.

1. Open Viber and go to More (⋮) → Settings → Notifications.

2 In the Notification Sound section, select a tune marked "Silent" (e.g., "Beep Once" or "Silent").

3. disable the option "Vibration" if it interferes.

• 🔊 Problem: MIUI The messenger can ignore the selected melody and play the system sound.
• 🛠 Solution: Reboot your phone after changing your settings – this resets the notification cache.
• ⚙️ Alternative: Install a third-party sound management app (e.g. Notification History Log).

If the volume hasn't changed after this manipulation, move on to the next one, and the problem is probably a conflict between Viber settings and MIUI system settings.

2. Volume setting via Xiaomi system menu

MIUI has separate volume sliders for different types of sounds: media, notifications, alarms and calls. Viber uses the Notification channel, so its volume is adjusted separately from music or video. Here's how to do it:

1. Press the physical volume button on the side panel of the smartphone.

2.In the menu that appears, touch the icon ⚙️ (gears) next to the slider.

3. Select "Notifications" and move the slider to the left to a comfortable level.

Important: on some Xiaomi models (e.g. Redmi 9 or POCO M3), this method is unstable due to firmware bugs. If the volume drops again after adjusting, try turning off the adaptive sound in the settings:

Settings → Sound and vibration → Adaptive sound → Disable

💡

If the notification volume slider is inactive, check if the phone has a Do Not Disturb mode or a Job profile.

3.Using Do Not Disturb mode for Viber

If you need to temporarily mute Viber (for example, overnight or during a meeting), use the Do Not Disturb (DND) system mode. Unlike a complete shutdown, you can configure exceptions here:

1. Go to Settings. → Don't disturb.

2. Select "Schedule" and set the time of automatic activation (for example, from 23:00 to 8:00).

3. In the "Exceptions" section, add Viber to the list of permitted applications, but tick only "No sound".

• 📱 Plus: Works even if Viber ignores system audio settings.
• ⏰ Disadvantage: You need to set the schedule manually.
• 🔕 Secret: B MIUI 14 there is an option "Silent mode for notifications" - it muffles the sound, but leaves a vibration.

For quick activation, add the "Do Not Disturb" label to the notification panel:

1. Swipe down from the top edge of the screen.
2. Press the pencil (✏️) panel-editing.
3. Drag the Do Not Disturb icon to the active area.

4. Change system sounds through ADB (for advanced)

If standard methods don’t work, you can manually change the volume of Viber via Android Debug Bridge (ADB), which requires connecting the phone to a computer, but gives you full control over the sound channels.

Step 1: Install ADB on your PC (download Google’s Platform Tools).

Step 2: Enable USB debugging on your phone:

Settings → About Phone → MIUI version (click 7 times)


Settings → Additional → For developers → Debugging by USB

Step 3: Connect your phone to your PC and execute a command to lower the volume of notifications to 30%:

adb shell media volume --stream 5 --set 3

--stream 5

--set 3

Install Platform Tools on PC|Enable debugging on USB Xiaomi|Connect your phone to the original cable|Check the connection with the adb device command-->

⚠️ Attention: Wrong commands ADB Before experimenting, back up your data through Settings. → Additionally. → Backup and reset.

If the volume dropped after the restart, fix the settings with the command:

adb shell settings put system notification_sound_volume 3

5. Installation of third-party applications for sound management

When MIUI system tools fail, third-party tools come to the rescue, and we tested 5 popular apps and selected the two most effective ones for Xiaomi:

1. Volume Styles (Play Market): 🎛 Allows you to divide the volume of notifications by application. 🔧 There are preliminary profiles for messengers. ⚠️ Requires Accessibility Service Rights.
2. MacroDroid (Play Market): 🤖 Automatically mutes Viber on schedule or geolocation. 📱 It works without root, but with restrictions on MIUI. 💡 You can create a rule: "If the screen is off → Turn the Viber sound down to 20%".

For installation:

1. Download the app from Google Play.
2. Launch and provide all the requested permissions.
3. In the "Profiles" or "Macros" section, create a rule for Viber.

⚠️ Attention: MIUI Some audio management apps may conflict with the system and cause notifications to freeze.

💡

The app side is the only way to divide the volume of notifications from Viber and other messengers (for example, make Telegram louder and Viber quieter).

6.Resetting the sound settings on Xiaomi

If all previous methods failed, the problem may be a failure of the system's sound settings, in which case resetting the sound parameters to the factory settings will help:

1. Go to Settings → System and device → Resetting.

2. Select "Resetting Sound Settings" (not to be confused with a full reset!).

3. Confirm the action and restart the phone.

After discharge:

• 🔄 All volume sliders will return to default values.
• 📱 You will have to reset notifications for Viber.
• 🎧 Check if the Bluetooth device settings (headphones, speakers) have reset).

This method helps in 80% of cases where Viber sound is unpredictable, and if the problem persists, it may be a corrupted firmware or a conflict with another application (such as Clean Master or DU Battery Saver).

7.Alternative solutions: disabling sound at the server level

Few people know, but Viber lets you manage some notification settings through the web version of the messenger, which is useful if nothing on the phone helps:

1. Open the Viber Web on your computer.

2. Authorize through QR-code.

3. Go to Settings (⚙️) → Notifications.

4. Turn off the "Sound Notifications" option or select the tune "None".

These settings are synchronized with the mobile app, but sometimes it takes up to 10 minutes to apply the changes.

• 📧 Unsubscribe from unnecessary chats or channels – they often generate unnecessary notifications.
• 👥 Create quiet groups where notifications come without sound.
• 🔕 Use the “Sleep Mode” function for individual chats (long tap on chat) → ⋮ → "Sleeping mode").

⚠️ Attention: Viber Web settings may reset after the messenger update. Check them after each update.
