Turn Charging Vibration On or Off auf Samsung
By default, Samsung phones confirm a connected charger with a short audio tone rather than a vibration. This is controlled by a dedicated entry inside the sound and vibration settings, separate from ringtone or notification sound controls.
Open Tap on Settings ➔ Tap on Sounds and vibration ➔ Tap on System sound/vibration control ➔ Enable or disable Charging. Toggling this entry switches the charging feedback to vibration and turns the tone off, or reverses it back to sound depending on the current state.
This setting only affects the charging confirmation itself. It does not change ringtone volume, notification vibration, or Do Not Disturb behavior, so it will not fix a phone that stays silent for calls or messages.
If your phone still does not vibrate on charging after enabling this option, check that the overall vibration intensity is not set to zero and that Do Not Disturb is not suppressing all haptic feedback during certain hours. A device in a case can also mute the physical sound of a vibration without it being disabled.
