Why Xiaomi is getting calls in “Do Not Disturb” mode – a full analysis of the causes and solutions

You have turned on Do Not Disturb (DND) mode on your Xiaomi, but calls still pass? This is a common problem that users of smartphones on MIUI face, from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra. The reasons can lie in both incorrect settings and software bugs of the firmware. In this article, we will examine in detail all possible scenarios why the Do Not Disturb mode ignores call blocking, and give step-by-step instructions for troubleshooting.

It's important to understand that MIUI has a unique approach to notifications and calls that is different from pure Android. For example, in some versions of the firmware, contact exceptions don't work as the user expects, and features like Priority Mode or Repetitive Calls may conflict with the basic rules of DND. We tested solutions on devices with MIUI 13-15 and identified patterns that will help you regain control over incoming calls.

1. Check the basic settings of the "Do Not Disturb" mode

Before you commit to a system bug, make sure that Do Not Disturb mode is set up correctly. Often users miss key settings that keep calling.

Settings → Notifications and Status Bar → Do not disturb

Please note the following points:

• 🔄 Schedule: If automatic time-out is enabled, check if the clock has gone off (for example, due to time zone change).
• 📞 Calls: This may include permission to skip calls from selected contacts or repeat calls (see next section).
• 🔔 Notifications: Sometimes only notifications are blocked and calls remain active.
• 🛠️ Exceptions: Check if apps (such as WhatsApp or Telegram) are accidentally added to the list of allowed apps.

If you see the Allow Interrupt option, that's the key. In MIUI 14+, it can be hidden under additional settings (stick the three-point in the upper right corner), and make sure that the mode doesn't automatically turn off when you connect to Bluetooth devices (like a car radio) -- a feature that some firmware has.

2. Repeated calls and exclusions for contacts

One of the most insidious features of MIUI is to allow repeat calls, which by default can skip a second call from the same number for 3 to 15 minutes, even if the Do Not Disturb mode is active, which is done for emergencies, but often goes wrong.

To disable this function:

1. Go to Settings. → Don't disturb. → Calls.
2. Find Repeat Calls (or Repeat Calls in New Versions).
3. Choose Not to Allow or Disable.

Also check the contact exceptions:

• 👥 Favorite Contacts: If you have a Favorite Number added, their calls can be automatically made.
• 📇 Contact groups: in MIUI Groups can be created (e.g., “Family” or “Work”) and allowed to be bypassed. DND.
• ⭐ Stars in contacts: in some versions of firmware, an asterisk next to the number gives priority.

If you use Google Contacts or sync with Mi Account, exceptions may be duplicated. For example, a contact added to Favorites on Google automatically gets priority in MIUI. To fix this, disable contact sync in Settings → Accounts → Google.

3. Conflict with applications and permissions

Some apps have special permissions to bypass Do Not Disturb mode, most often messengers (WhatsApp, Viber, Telegram), call apps (Skype, Zoom) or system services (Mi Dialer).

How to check and disable:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as WhatsApp) → Permissions → Change system settings.
3. Turn off the permission to Bypass Do Not Disturb mode (may be called Notification Management or Priority Notifications).

Pay particular attention to:

• 📱 Phone: Sometimes after updating it resets the settings and starts to ignore DND.
• 🔊 Call recording apps: They often request privileges to work seamlessly.

If the problem occurs after installing a new app, try running your phone in Safe Mode (press the Power button → Safe Mode).This mode only runs system applications - if calls are blocked, third-party software is to blame.

4. firmware bugs and setting reset

If all the settings are correct, but the calls still pass, the reason may lie in MIUI bugs.

• 🆕 Beta versions of firmware (for example, MIUI 15 Developer ROM).
• 📱 Smartphones with custom firmware (for example, Xiaomi.eu or LineageOS).

Solutions:

1. Reset the "Do Not Disturb" settings**:
2. Clear the cache of system applications**:
3. Update the firmware** (if a new version is available):

For devices with MIUI 14+ based on HyperOS, resetting all notification settings can help:

Settings → Notifications and Status String → Additional → Resetting Notifications

💡

If you still have a problem after updating your firmware, try to roll back to the previous version via Fastboot or Mi Flash Tool.

If the bug only appears with certain SIM-cards (for example, calls are only on Simka 1, but blocked on Simka 2), try:

• Change. SIM-squat-in-the-box.
• Update the operator settings: Settings → SIM-maps and mobile networks → Operator settings → Update profile.

5. Features of working with two SIM-map

On Xiaomi’s Dual SIM-enabled smartphones (like the Redmi Note 13 Pro+ or POCO X6 Pro), the Do Not Disturb mode can work differently for each SIM card.This is because MIUI processes calls from different carriers as separate events.

How to set up:

To synchronize settings for both SIMs:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose. SIM-map → Call settings.
3. Make sure that both SIMs have the "Do Not Disturb" setting enabled.

If one of them SIM-The card belongs to the corporate tariff, the operator can ignore the settings DND This is true for MTS, Beeline and MegaFon with business rates. To check, call from another phone to each one. SIM turn-on.

6. Alternative ways to block calls

If the standard Do Not Disturb mode is unstable, use alternative methods:

1. In-plane mode with Wi-Fi enabled:

• 🛩️ Includes full network lock, but allows you to use Wi-Fi and Bluetooth.
• ⚠️ Minus: You won't get it. SMS push notifications (except those that come via Wi-Fi, for example, in Telegram).

Notification Panel → Mode "On the plane" → Enable Wi-Fi manually

2. applications for blocking calls:

• 📲 Call Blocker (from Xiaomi) – built-in solution with flexible rules.
• 🔒 Truecaller – blocks spam and unknown numbers, but can conflict with DND.
• 🛡️ Blacklist – allows you to create blacklists by number masks.

Operator settings:

• 📡 Some operators (such as Tele2) have an Antispam service that blocks calls at the network level.
• 💳 Check if you have a Call Redirection service (can redirect calls to another number without passing through the phone). DND).

💡

If you need to completely turn off calls for a certain time, use the combination "On the plane" + alarm clock, which is guaranteed to block all calls, but will retain the ability to use the phone for other tasks.

MIUI 15 (HyperOS) users can use Focus Mode, which allows you to create separate profiles for work, sleep or rest with flexible rules for calling, to configure it:

Settings → Digital Well-Being → Focus Modes → Create a New One

7. When to contact the service center

If none of these things worked, the problem could be hardware.

• 📵 Damaged communication module (for example, after falling or getting moisture).
• 🔋 Faulty. SIM-cards or slots (try inserting) SIM other-phone).
• 🔄 Failure after firmware (for example, if the phone was stitched with unofficial software).

Signs of hardware malfunction:

• Calls are even made in "Airplane" mode.
• The phone spontaneously reboots when an incoming call.
• There's no network on one of them. SIM-The card, but the calls are on.

💡

Before visiting the service center, back up your data via Settings → About Phone → Backup or Mi Cloud. This is free and takes 5-10 minutes.

If your Xiaomi is guaranteed, contact the official service center. the list of addresses can be found on the website of Xiaomi Russia. For devices older than 2 years, repairs can cost 1,500-5 000 ₽ depending on the model and breakdown.

⚠️ Don’t trust the “private masters” who offer to reflash the phone for 500 ₽. Incorrect firmware can completely disable the device, and the warranty will burn down.
