When Do Not Disturb keeps turning on by itself on the vivo S50, notifications can go silent without warning. Calls may not ring, alerts disappear, and it feels like the phone is ignoring you. This usually happens because of automation features, schedules, or system rules inside Funtouch OS, not because the phone is broken.
Why Your vivo S50 Turns On Do Not Disturb Automatically
- A scheduled DND rule is enabled.
- Focus or sleep modes are activating DND in the background.
- App permissions are allowed to control system settings.
- Automation features are triggering DND based on time or location.
- Temporary software glitches after an update.
1. Check Do Not Disturb Schedule
Do Not Disturb can turn itself on if a schedule is active. Many users enable this once and forget about it, which causes DND to activate at the same time every day.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and then tap Schedule to turn it off.
2. Disable Sleep or Focus Modes
Sleep or focus features often control Do Not Disturb automatically. If one of these modes is active, DND will keep enabling itself even when you turn it off manually.
Open Settings, and then tap Digital Wellbeing and parental controls.
Tap Sleep or Focus mode, and then disable any active schedules.
3. Check App Permissions That Control DND
Some apps are allowed to change system settings. When this permission is enabled, an app can turn on Do Not Disturb without asking.
Open Settings, and then tap Privacy.
Tap Permission manager, and then review apps with access to system controls.
4. Turn Off Automation or Smart Rules
Automation features can trigger actions like enabling DND based on time, location, or behavior. These rules run silently in the background.
Open Settings, and then tap Shortcuts and automation.
Tap Automation rules, and then disable any rule linked to Do Not Disturb.
5. Restart the Phone
A temporary system glitch can cause DND to behave unpredictably. Restarting refreshes background services and clears minor software issues.
Swipe down from the top of the screen to open Quick Settings, and then tap the Power icon.
Tap Restart, and then wait for the phone to fully boot.
6. Reset Sound Settings
If the issue keeps returning, sound settings may be corrupted. Resetting them restores default behavior without deleting personal data.
Open Settings, and then tap System management.
Tap Reset options, and then select Reset sound and vibration settings.
Once Do Not Disturb stops activating on its own, notifications should behave normally again. After disabling schedules and automation, the vivo S50 stays silent only when you want it to.
FAQs
Why does Do Not Disturb turn on at night on my vivo S50?
This usually happens because a sleep or schedule rule is active. Disabling those features prevents DND from turning on automatically.
Can third party apps enable Do Not Disturb by themselves?
Yes. Apps with permission to modify system settings can control DND. Reviewing app permissions helps stop this behavior.
Will resetting sound settings delete my data?
No. Resetting sound and vibration settings only restores defaults for audio features and does not affect apps, photos, or files.
