What to do when you can't adjust the volume on your Samsung Galaxy device

Check if the device has been set to Mute mode. This silences all sounds without using the Volume buttons:

1. Swipe down from the top right corner of the screen.
2. Tap the Settings icon.
3. Tap Sounds and vibration, and check if Mute mode is selected.
4. Change to a different mode (e.g., Sound or Vibrate) to restore sounds.

If all sounds are muted and a popup related to accessibility appears when adjusting the volume, the Mute all sounds feature may be enabled. To disable it:

1. Open Settings, then tap Accessibility.
2. Tap Hearing enhancements, then turn off Mute all sounds.

Adjust the volume levels for call ringtones, notifications, media, and system sounds:

1. Swipe down from the top right corner of the screen.
2. Tap the Settings icon.
3. Tap Sounds and vibration, then tap Volume.
4. Drag the sliders for each sound type.

Turn off Do not disturb or adjust settings for blocked sounds and notifications:

1. Swipe down from the top right corner of the screen.
2. Tap the Settings icon.
3. Tap Notifications, and then tap Do not disturb.
4. Turn off the switch to disable Do not disturb and allow all sounds and notifications.   
5. If you prefer to use Do not disturb, turn on the switch to enable it, then configure exceptions for Calls and messages, App notifications, and Alarms and sound.

A temporary system error may affect sound output.

1. Swipe down from the top right corner of the screen.
2. Tap the Power off icon, and then tap Restart.
3. Tap Restart again to confirm. The device will automatically restart.
    

Alternatively, press and hold the Side button and Volume Down button at the same time for more than 7 seconds until the device restarts automatically.

Outdated software or apps may cause compatibility issues or abnormal display behavior, including display or sound-related problems.
 

Check for software updates

To ensure your device is running the latest software:

1. Open Settings, then tap Software Update.
2. Tap Check for updates to check for available software updates.
3. If an update is available, follow the prompts to download and install it. 

Check for app updates

To ensure your device functions properly, including sound-related apps like Sound Assistant, check for and install app updates:

1. Open the Google Play Store app, then select your Google account.
2. Tap Manage apps & device to check for available updates.
3. Tap Update all to install available updates for all apps.

If the Volume buttons are unresponsive or malfunctioning, inspect them for physical damage caused by external impact or wear and tear. Signs of damage may include:

• Visible cracks, dents, or deformities in the buttons.
• Sticky or jammed buttons that don't press smoothly. 
• Unresponsive buttons that don't register when pressed.

Stop using the device immediately and visit a nearby Samsung service center to have the device inspected.
