If Do Not Disturb keeps turning on by itself on your Galaxy S26 Ultra, you may miss calls, messages, and important notifications without realizing it. This issue usually happens because of scheduled routines, automation features, or synced settings that trigger it in the background. The good news is that in One UI 8.5, you can track down what is causing it and stop it for good.
Why Your Galaxy S26 Ultra Turns On Do Not Disturb Automatically
- A Do Not Disturb schedule is enabled.
- Modes and Routines are triggering it based on time or location.
- Sleep mode is activating it during certain hours.
- Sync settings are turning it on from another device.
- A temporary system glitch is re-enabling the feature.
1. Check Do Not Disturb Schedule
A schedule can automatically turn Do Not Disturb on and off at specific times. Many users enable this once and forget about it, which causes the feature to activate unexpectedly.
Open Settings, and then tap Notifications.
Tap Do Not Disturb, and then tap Schedule.
Turn off the schedule, or adjust the time to your preference.
2. Turn Off Modes and Routines
Modes and Routines can silently enable Do Not Disturb based on conditions like location, time, or activity. This is one of the most common reasons the feature keeps turning on by itself.
Open Settings, and then tap Modes and Routines.
Tap Routines, and then review any active automation.
Disable or edit routines that include Do Not Disturb actions.
3. Check Sleep Mode Settings
Sleep mode often includes Do Not Disturb as part of its configuration. If it is active, your phone will automatically silence notifications during bedtime hours.
Go back to Settings, and then tap Modes and Routines.
Tap Sleep, and then review its settings.
Turn off Do Not Disturb inside Sleep mode, or disable Sleep mode entirely.
4. Disable Sync Across Devices
Samsung devices can sync Do Not Disturb status across multiple devices. If another device activates it, your Galaxy S26 Ultra may follow automatically.
Open Settings, and then tap Connected devices.
Tap Sync settings, and then look for Do Not Disturb sync.
Turn off syncing to prevent other devices from controlling it.
5. Restart Your Phone
Sometimes a temporary software glitch can cause Do Not Disturb to turn on repeatedly. Restarting your phone refreshes system services and clears minor bugs.
Swipe down from the top right of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
Wait for the phone to reboot and monitor if the issue returns.
6. Reset Notification Settings
If the problem persists, your notification settings may be misconfigured. Resetting them can remove hidden triggers that keep enabling Do Not Disturb.
Open Settings, and then tap General management.
Tap Reset, and then tap Reset all settings.
Confirm the reset and reconfigure your preferences afterward.
Do Not Disturb turning on by itself can be frustrating, but it is almost always tied to a setting or automation running in the background. Once you disable schedules, routines, or syncing features, your Galaxy S26 Ultra should stop enabling it without your input.
FAQs
Why does Do Not Disturb turn on at night automatically?
This usually happens because Sleep mode or a scheduled routine is active. Disabling these settings will stop automatic activation.
Can another Samsung device turn on Do Not Disturb on my phone?
Yes. If syncing is enabled, another device connected to your account can trigger Do Not Disturb on your Galaxy S26 Ultra.
Will resetting settings delete my data?
No. Resetting settings only restores system preferences to default. Your apps, photos, and files will remain untouched.
