If Do Not Disturb keeps turning on by itself on your OnePlus 15, notifications can suddenly stop coming through. Calls may be silenced, alerts may not appear, and it can feel like the phone is ignoring you. This usually happens because of automation settings, schedules, or system features that quietly control sound behavior in the background.
Why Do Not Disturb Keeps Turning On on OnePlus 15
- A Do Not Disturb schedule is enabled without you noticing.
- Bedtime Mode or Digital Wellbeing is activating it automatically.
- Focus Mode is linked to Do Not Disturb.
- Automation rules or routines are controlling sound settings.
- A system glitch caused by recent changes or updates.
1. Turn Off the Do Not Disturb Schedule
Do Not Disturb can turn itself on if a schedule is active. This setting allows the phone to silence notifications at certain times, even if you did not mean to use it.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and then tap Schedule to turn it off.
2. Disable Bedtime Mode
Bedtime Mode automatically enables Do Not Disturb to reduce distractions while sleeping. If it is turned on, your OnePlus 15 may keep silencing notifications every night or at random times.
Open Settings, and then tap Digital Wellbeing and parental controls.
Tap Bedtime mode, and then turn it off completely.
3. Check Focus Mode Settings
Focus Mode is designed to block distractions, and it often works together with Do Not Disturb. If Focus Mode is active, it can force Do Not Disturb to turn on automatically.
Open Settings, and then tap Digital Wellbeing and parental controls.
Tap Focus Mode, and then disable all active focus profiles.
4. Turn Off Automation or Routines
Some OnePlus phones allow automation rules that control system behavior based on time, location, or usage. These rules can silently enable Do Not Disturb without showing a clear warning.
Open Settings, and then tap System settings.
Tap Automation or Routines, and then disable any rules linked to sound or notifications.
5. Restart the Phone
If none of the settings appear to be responsible, the issue may be a temporary system glitch. Restarting refreshes background services and often stops Do Not Disturb from activating again.
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 boot back up.
Once Do Not Disturb is no longer being triggered by schedules or system features, your OnePlus 15 should behave normally again. Notifications will arrive as expected, and sound settings will stay under your control.
FAQs
Why does Do Not Disturb turn on at night on my OnePlus 15?
This usually happens because Bedtime Mode or a DND schedule is enabled. Turning these features off stops the automatic activation.
Can apps force Do Not Disturb to turn on?
Most apps cannot do this directly, but Digital Wellbeing features and system automation can control Do Not Disturb without asking each time.
Will resetting settings fix this issue?
In most cases, adjusting schedules and modes is enough. A full settings reset is rarely needed unless the problem continues after all fixes.
