Check vibration controls and notification delivery first; menu names vary by Galaxy Watch model and software version.
Check the watch’s vibration controls
On the watch, open Settings > Sounds and vibration. Samsung’s settings guidance identifies separate controls for notification vibration and system vibration, along with call vibration, vibration length and strength, sound mode, volume, ringtone, and notification sound. The exact options depend on the model and software version. A setting may be labelled “Vibrate with sound” or “Vibrate while ringing.” Samsung’s sound-settings guide describes the available controls.
Review the notification and system vibration options rather than changing every sound setting at once. If the vibration stops when you adjust one category, that points to the kind of alert involved, though it does not identify the specific triggering event.
Review which notifications reach the watch
In the Galaxy Wearable app on your phone, go to Watch settings > Notifications. Check which apps are allowed to notify the watch and review the phone-notification delivery option. The labels and available choices vary by device and software version.

On supported versions, Samsung describes options including “Smart device selection” and “Always show on both.” Choosing to show notifications on both phone and watch can make both devices alert for the same notification and may affect battery use. See Samsung’s notification and alert guidance for details.
Check Watch only mode and Bluetooth alerts
Samsung advises checking that Watch only mode is off and reviewing vibration options for Bluetooth disconnection alerts as well as notifications. A watch may therefore vibrate because its connection state changed, even when no new app notification is apparent. Find these controls in the watch settings; the path and labels can differ by model. Samsung’s vibration troubleshooting page covers these checks.

Restart the watch if the checks do not help
- Press and hold both physical buttons on the watch.
- Keep holding until the Samsung Galaxy screen appears. Samsung Canada says this takes approximately seven seconds.
- After the watch restarts, see whether the unexplained vibration continues.
Button names and device behavior can vary by model. Samsung Canada provides this restart step in its Galaxy Watch vibration troubleshooting guidance.

If the vibration persists after checking alert settings and restarting, inspect the watch for physical damage and contact Samsung support with your exact model and software version. Samsung’s general guidance does not establish that vibration by itself indicates a damaged vibration motor or any other specific hardware fault; a model-specific assessment is needed to diagnose the device.
