Schedule Do Not Disturb Automatically auf Samsung
Manually toggling Do Not Disturb only works if you remember to switch it back off. On Samsung phones running Android with One UI, a schedule handles both the start and the end automatically, based on days and times you define once.
Where the schedule lives
The setting sits inside the notification settings, not in Quick Panel controls. That is why many users only find the manual toggle and miss the option to automate it.
To create one: Tap on Settings ➕ Tap on Notifications ➕ Tap on Do not disturb ➕ Tap on Add schedule ➕ Enter a Name ➕ Set the Days and Start/End time and tap Save.
The name field matters if you plan more than one schedule, for example a work-hours block and a separate overnight block. Each schedule runs independently once saved.
A scheduled Do Not Disturb still follows whatever exceptions you already configured, such as allowed calls or apps. If notifications still come through during the scheduled window, check those exception lists rather than the schedule itself.
