Why is the “Do Not Disturb” mode on Redmi 9 not switched off?
The Do Not Disturb (DND) mode on Xiaomi Redmi 9 is a useful feature for blocking notifications, but sometimes it behaves unpredictably, as users experience the mode not turning off through the notification panel, continuing to work after a reboot or activating spontaneously, the reasons may lie in:
MIUI crashes: Redmi 9 firmware (especially MIUI 12-14) is known for notification management bugs, for example, after an update, the system may “forget” to return the DND settings to its original state.
Schedule conflicts: If the mode is on by timer (for example, overnight), but time is lost due to manual time zone change, it can remain active forever.
Hidden exceptions: Some apps (messengers, banking services) have privileges to bypass DND, but their settings may conflict with the basic rules.
Before you start shutting down, check to see if Priority Mode (a type of DND in MIUI) is activated, which blocks all notifications except for selected contacts. Its icon on the notification bar looks like a star in a circle, not like a crescent.
Method 1: Quickly shut down via notification panel
The most obvious method is to use a notification curtain. On Redmi 9, it works 90% of the time, but there are nuances:
- Swipe your finger down the screen to open the notification bar.
- Find the icon. 🌙 Don't disturb (or) 🔕 Priority Mode. If you don't have one, swipe down again to turn the full panel around.
- Stick on the icon once. It has to go out, which means that the mode is off.
⚠️ Note: If the icon does not respond to the press or immediately lights up again, then the mode is blocked by the device administrator (for example, through Settings). → Special opportunities → Simplified mode) or activated on a schedule.
☑️ Pre-switch check DND
Method 2: Disconnecting through MIUI settings
If the quick method didn't work, you'll have to dig deeper. In MIUI, the "Do Not Disturb" settings are hidden in the notification section, but their location depends on the firmware version:
- Open Settings → Notifications and Status bar → Do not disturb.
- At the top of the screen, find the “On” switch – move it to the left to turn off the mode.
- Scroll down and check the Schedule section. If it has rules (like 23:00 to 7:00), delete them or turn off the Automatic slider.
🔍 The Hidden Trap: In Some Versions MIUI (for example, MIUI 13.0.4 for Redmi 9 settings DND duplicated in the settings → Sound and vibration → If you can't find them on the first track, check the second!
| MIUI version | The Way to DND Settings | Features |
|---|---|---|
| MIUI 12 | Settings → Notifications → Do not disturb | There is no separate Schedule section – the rules are customized in the main menu. |
| MIUI 13-14 | Settings → Notifications and Status Bar → Do not disturb | There is an “Exceptions” section with priority contacts. |
| MIUI for POCO | Settings → Sound → Do not disturb | The interface is simplified, there is no separation into “Schedule” and “Exceptions”. |
Method 3: Reset notification settings (if the mode is “hang”)
If Do Not Disturb is not disabled even through the settings, the problem may be in the corrupted configuration files, in which case resetting the notification settings without losing data will help:
- Open Settings → Applications → Application Management.
- Slip on the three dots in the top right corner and select Reset App Settings.
- Confirm action. This will return all notification permissions to factory settings, but it won't delete personal data.
⚠️ Note: After resetting, you will have to reset notifications for instant messengers (such as WhatsApp or Telegram), as all exceptions will be removed.
💡 Alternative: If the reset didn't help, try clearing the cache of the com.android.systemui system application (responsible for the notification bar:
Settings → Applications → Show all applications (3 points) → Show system → System UI → Storage → Clear cacheMethod 4: Disconnect via ADB (for power users)
If the software methods don’t work, it’s ADB debugging. This method requires a computer and basic command line knowledge, but is guaranteed to disable Do Not Disturb even if it’s locked at the system level.
📌 What's the matter:
- 🖥️ Computer with installed ADB Tools.
- 📱 Included debugging by USB Redmi 9 (Settings) → The phone. → Version. MIUI → 7 times to tap according to the version → return to Settings → Additionally. → For developers → Debugging by USB).
- 🔌 USB-cable (preferably original).
🛠 Step-by-step instruction:
- Connect Redmi 9 to your computer and confirm the debugging permission on your phone.
- Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with adb.exe.
- Enter the command to check the connection: Adb devices must appear serial number of your device.
- Execute the shutdown command. DND: adb shell settings put global zen_mode 0 Here. 0 — off-line».
- Reboot your phone: adb reboot
If the mode is activated again after the reboot, it is blocked by device policies (for example, in corporate phones), in which case only a factory reset will help.
What if the ADB can’t see the device?
Method 5: Checking Schedule and Exclusions
Often, the Do Not Disturb mode is not turned off due to hidden rules that the user forgot to configure. MIUI possible:
- 🕒 Set a schedule for the days of the week (for example, only on weekdays).
- 📱 Set exceptions for applications (messaging, calls).
- 🔕 Enable automatic on when connecting to Wi-Fi or charging.
🔍 How to check:
- Go to Settings → Notifications and Status bar → Do not disturb → Schedule.
- Remove all rules by tapping on each and selecting Remove.
- In the Exclusions section, check if there are any ticks opposite Calls, Messages or Alarms, which sometimes conflict with the basic settings.
⚠️ Note: If you use a job profile (e.g., through Google Family Link or corporate policies), the Do Not Disturb settings can be managed by an administrator, in which case you can only turn off the mode through your organization account.
💡
If the mode turns on on itself at night, check the “Sleeping” settings in the Mi Health or Google Wellbeing app – these can duplicate DND features.
Problem Solving: When Nothing Helps
If all options are exhausted and the Do Not Disturb regime is still active, radical measures remain:
| Problem. | Decision | Risks. |
|---|---|---|
| The mode is activated after restarting | Resetting settings to factory (Settings → About phone → Resetting) | Delete all data except files on SD-map |
| DND icon is inactive (gray) | Administrator rights check (Settings → Passwords and security → Device administrators) | Security settings may be reset |
| ADB does not turn off the mode | Fastboot Flashback (only for power users!) | Risk of “bricking” the device |
🔧 Last chance: If the phone is warranty, contact Xiaomi Service Center. In some cases, the problem is related to a hardware failure (for example, damage to the power connector, which mistakenly activates the power saving mode.
💡
Before resetting, be sure to back up via Settings → Additional → Backup and Reset or Mi Cloud.This will save contacts, photos and app settings.
