If your Galaxy A56 keeps switching between sound, vibrate, and silent mode on its own, you are not alone. This issue can be caused by certain settings, third-party apps, or even connected devices that control audio modes. Fortunately, there are several ways to stop your phone from changing sound modes automatically.
Why Your Galaxy A56 Keeps Changing Sound Mode
- Do Not Disturb or Bedtime mode is enabled.
- A connected wearable or Bluetooth device is managing the sound profile.
- Third-party apps have permission to modify system settings.
- Accidental taps or gestures trigger silent or vibrate mode.
- Temporary software bugs or glitches in One UI.
Check Do Not Disturb and Bedtime Mode.
These modes can silence calls and notifications automatically during specific hours. If they are enabled, your phone may keep switching to silent or vibrate without you realizing it.
- Open Settings, and then tap Notifications.
- Tap Do Not Disturb, and then make sure it is turned off.
To check Bedtime mode:
- Open Settings, and then tap Modes and Routines.
- Tap Sleep, and then disable Bedtime mode if it is active.
Disconnect Bluetooth or Wearable Devices.
Smartwatches or wireless earbuds sometimes control sound profiles when connected. To test if they are the cause, disconnect them temporarily.
- Swipe down from the top-right of the screen to open Quick Settings.
- Tap the Bluetooth icon to turn it off, and observe if the issue stops.
If you use a Galaxy Watch, open the Galaxy Wearable app and check if sound or notification syncing is turned on.
Review App Permissions.
Some apps can toggle silent or vibrate mode for notifications or reminders. Checking app permissions helps prevent this behavior.
- Open Settings, and then tap Apps.
- Tap the three-dot menu, and then select Special access.
From here, tap Modify system settings, and review the list. If you find an app that should not control sound settings, toggle its permission off.
Reset Sound Settings.
Restoring default sound configurations can clear up bugs or misapplied changes from updates.
- Open Settings, and then tap Sounds and vibration.
- Tap Sound mode, and then select Sound to reapply it manually.
You can also tap Volume and set your preferred levels again.
Update Software.
Sometimes, sound-related glitches come from firmware bugs that Samsung fixes through updates.
- Open Settings, and then tap Software update.
- Tap Download and install, and follow the prompts if an update is available.
After updating, restart your phone and test if the problem persists.
If your Galaxy A56 continues to change sound modes by itself, a third-party app or automation routine could be the cause. Disabling or uninstalling suspicious apps usually resolves the problem.

Can a smartwatch change my Galaxy A56 sound settings?
Yes. Connected Galaxy Watches or Bluetooth accessories can sync and control notification settings, which might change the sound mode.
Will a factory reset fix this issue?
