Why the “Do Not Disturb” mode turns on itself on Xiaomi: reasons and solutions

Have you noticed that your Xiaomi, Redmi or Poco do not disturb mode (DND) activates without you? notifications disappear, calls do not come, and the status bar is burning familiar crescent icon? This problem occurs on devices with MIUI versions from MIUI 12 to HyperOS, and its causes can be hidden in software bugs and non-obvious settings.

In this article, we will discuss 7 the main reasons for the spontaneous inclusion of the “Do Not Disturb” mode, including hidden triggers in the MIUI, Conflicting applications and hardware failures. You'll also learn how to disable automatic triggering. DND Once and for all, without resorting to resetting. 13/14, Redmi Note 12 POCO F5, where the problem is most often.

1. Automatic rules in the "Do Not Disturb" settings

The most common reason is forgotten or randomly created rules in the DND mode itself. MIUI allows you to set up automatic turn on by time, events or geolocation, and these settings can work unnoticed by the user.

To check:

• 🕒 By time: Go to Settings → Sound and vibration → Don't disturb. → Automatic rules: Remove all unnecessary schedules (e.g., Night Mode or Sleep Time»).
• 📍 By location: Check the rules like “Home” or “At Work” on the same menu – they can be activated when you connect to a specific Wi-Fi network.
• 🔄 In the event: some firmware include DND When connecting to Mi Band or during Focus Mode.

If you didn’t create the rules yourself, they could have been added by a system update or a third-party app (like Google Calendar or Mi Fit). In MIUI 14+, these settings are sometimes duplicated in Settings → Digital Well-being – check there.

2.Conflict with sleep or focusing apps

Sleep tracking apps (Mi Fit, Sleep as Android, Google Health Connect) or concentration apps (Forest, Focus To-Do) often have built-in DND integration. They can include Do Not Disturb mode on schedule or when you detect sleep (via motion sensors or connected gadgets).

How to check:

1. Open the settings of each such application and find items like Do Not Disturb, Sleep Mode or Automation.
2. In Mi Fit, look at Profile → Settings → Notifications → Sleep Mode.
3. In Google Calendar, check for events marked Sleep – they can automatically activate DND.

HyperOS (starting with Xiaomi 14) has a feature called “Intelligent Sleep Mode,” which analyzes your schedule and includes DND based on data from Mi Band or Smart Clock. It can be turned off in Settings → Connected Devices → Smart Features.

💡

If you use Mi Band, check the Settings → Notifications → Sleep Mode section in its app, sometimes it duplicates rules from MIUI, which leads to double DND activation.

3. Mishapes in MIUI or HyperOS

Software bugs are the second most common cause of spontaneous DND activation, especially in:

• 📱 Beta Assembles (firmware marked Beta or Developer)
• 🔄 Recent updates (in the first 1-2 weeks after the release of the new version) MIUI)
• 🛠️ Modified firmware (for example, Xiaomi.EU or customized firmware) ROM)

Typical symptoms of the bug:

• DND is turned on when the device is restarted.
• The mode is activated when connecting / disabling charging.
• Notification Log (Settings → Notifications → Notification Log) does not have manual inclusion records.

Decisions:

1. Clear the cache of system applications: Settings → Annexes → Application management → Three points (⋮) → Show system-based → Find "Don't disturb" → Warehouse → Clear the cache
2. Reset the settings. DND: Settings → Sound and vibration → Don't disturb. → Three points (⋮) → Reset the settings
3. If the problem appears after the update, roll back to the stable version via Settings. → The phone. → Updating the system → Three points (⋮) → Select a Service Package.

4. Hardware problems: power button or sensors

Less commonly, but accurately: spontaneous DND activation may be associated with physical malfunctions:

• 🔋 Sticking of the power button (if) DND It's activated when you press it).
• 📡 Failure of the proximity sensor (for example, when talking on the phone).
• 🔌 Problems with the charging connector (on some Redmi models) DND It works with poor contact).

How to diagnose:

1. Check if the DND is turned on when you press the power button (especially if it is wobbly or pressed poorly).
2. Run the hardware test using the code ##6484## (on some models) or the Mi Diagnostics app.
3. See if the DND on is matched by vibration or sounds (this may indicate a short circuit in the button).

⚠️ Warning: If the problem is with the power button, don’t try to disassemble the phone yourself – on Xiaomi models 12/13 It is integrated into a flexible plume board, and unprofessional repairs can lead to loss of leakage.

Conflict with energy-saving regimes

There are two energy saving modes in MIUI that can affect DND:

1. Ultra-power saving mode (Settings → Battery → Energy saving mode → Ultra): restricts background activity and can force "Do Not Disturb".
2. Adaptive battery (Settings → Battery → Settings → Adaptive battery): In HyperOS, it analyzes the user’s habits and can activate DND during “calm” hours.

Also check:

• 🔋 Energy saving schedule in Settings → Battery → Energy saving regime → Schedule.
• ⚡ Charging optimization (Settings) → Battery → Settings → Charging optimization – on some models it includes DND when reaching 100%.

6. Viruses or malicious applications

Some viruses or aggressive applications (especially from third-party sources) can change system settings, including DND.

• 📲 DND Included when installing new applications.
• 🔄 In Settings → Annexes → Permissions are unknown programs with access to Change System Settings.
• 📊 In Settings → Battery → Battery use is seen by unfamiliar processes consuming a lot of energy.

What to do:

Remove suspicious apps | Check permissions in Settings → Apps → Permissions → Change system settings | Run scanning through Google Play Protect (Play Store → Menu → Play Protect) | Install Malwarebytes or Dr.Web Light for deep check |Reset network settings (Settings → Network & Internet → Reset Wi-Fi, Mobile Network and Bluetooth)

-->

If the virus is found but not removed, reset to factory settings (Settings → About Phone → Settings Reset).

7. Reset network settings or update firmware

If none of these methods worked, radical measures remain:

Option 1: Reset network settings

Sometimes DND malfunctions are due to incorrect mobile network or Wi-Fi settings. Network resets can help:

Settings → Network and Internet → Reset Wi-Fi, mobile network and Bluetooth

Option 2: Manual flashing

If the problem has occurred after the MIUI update, try:

1. Download the full firmware (not OTA!) for your model from the official Xiaomi website.
2. Refuse the phone through Settings → The phone. → Updating the system → Three points (⋮) → Select a Service Package.
3. If custom firmware is used (e.g. Xiaomi.EU), go back to the official global version.

⚠️ Warning: When manually firmware, don't interrupt the process and make sure the battery is over 50%.On Xiaomi 13 Ultra and Redmi models K60 Pro for firmware may require unlocking the bootloader (fastboot oem unlock).

💡

If DND only turns on when you connect to a specific Wi-Fi network, the problem may be in the router. Try changing the Wi-Fi channel in the router settings (from 2.4 GHz to 5 GHz or vice versa).
