Timer Vibration On/Off auf Samsung
Samsung splits timer alerts into two independent controls: the timer tone and the timer vibration. Changing your ringtone volume or switching to a vibrate profile does not automatically enable this option, because the Clock app manages it on its own.
To switch it on or off, open Clock and tap Menu. From there go to Settings and use the toggle to Enable or disable Vibration. The change applies immediately to every timer you start afterward, including saved presets.
Vibration is useful when the phone is in a pocket, under a pillow, or in a noisy room where the tone alone might not register. It also helps when the ringer volume is turned low but you still want a physical cue when the timer ends.
If you rely on the timer for focus sessions or workouts and the phone is far away, vibration alone will not help since you need to be in physical contact with the device. In that case, raising the timer tone volume or using a connected wearable is the better fix.
This setting only affects timer alerts. Alarm and stopwatch vibration are controlled separately inside their own tabs in the Clock app.
