Xiaomi and Redmi smartphone owners often face a situation where the device stops making notifications or incoming calls for no apparent reason. Usually this means that the Do Not Disturb system profile has been activated, which blocks all external stimuli. Unlike a simple silent mode, this feature completely ignores incoming signals, which can lead to the missing of an important call or message.
MIUI interfaces and the new HyperOS offer flexible settings for this mode, allowing you to create schedules and exceptions. However, sometimes users forget about the timers turned on or encounter software failures when the crescent icon is constantly burning. In this article, we will discuss all the ways to force and automatically disable this feature, and also consider hidden settings that can interfere with the normal operation of the sound system.
You can unlock your phone in a variety of ways, from quick access through the notification curtain to deep settings in the system menu. It's important to understand the difference between normal silent mode and total ignoring of events, because the ways to deactivate them can vary depending on the firmware version, and we'll help you get the sound and notifications back to normal.
⚠️ Note: If Do Not Disturb mode turns on on its own after a reboot, check the list of installed apps.Some alarm programs or sleep trackers may have permission to manage this profile.
Quick shutdown through the control panel and curtain
The easiest and fastest way to get sound back is to use the control center. On most modern Xiaomi and Redmi models, it is enough to swipe down from the top right corner of the screen (or from the entire top edge in older versions of MIUI) to open the Quick Settings panel, and there is a crescent icon that lights up in blue or orange when the mode is activated.
Just click on this icon to deactivate the function. If the crescent icon is missing from the panel after pressing, but it remains in the status bar (at the top of the screen), perhaps the "Alarm Only" or "No Sound" mode is activated, in which case you need to click on the speaker icon with a cross-over sign or use a side volume swing to switch the sound profile.
Sometimes the system can stick and the visual display of the mode does not correspond to the real state. If you click on the icon but the sound does not appear, try changing the volume of the media or ringtone. This action often wakes the audio system and resets the mistaken profile status.
Schedule and automation in the menu
Often users will accidentally activate the automatic activation of the mode on a schedule. To check this, you need to go to the deep settings menu. Navigation may vary slightly depending on the version of the shell, but the general path usually looks like this: Settings → Sound and vibration → Do not disturb.
In this section, you'll find a Scheduled or Scheduled Switch. If it's active, the system will automatically block notifications at a specified time. It's a useful feature for sleep, but it can become a problem if you forget it exists. Make sure the slider is set to Off.
☑️ Checking schedule settings
Also on this menu, you should pay attention to the item "Repeat": Even if you manually turned off the mode, the next time it comes out of the schedule, it will turn on again. Automation in MIUI is more important than manual settings, so removing the schedule is a must-do step to completely solve the problem.
Set up exceptions and selected contacts
Do Not Disturb mode doesn't always mean complete silence. It allows you to create a list of exceptions that sounds will pass through even when an active profile is in place. This is especially true for important contacts or repeated calls from a single number. This option is located along the way: Settings → Sound and vibration → Do not disturb → Exceptions.
You can set up a Favorite Contacts pass or allow repeat calls, and the Repeat Calls function works like this: if the same number rings a second time in 3-5 minutes, the phone will ring, and it's an emergency safety mechanism.
| Type of exception | Description of function | Recommendation |
|---|---|---|
| Selected contacts | Sound only for numbers from the list of contacts with an asterisk | Add close relatives |
| Repeated calls | Passing the sound on the second call in 5 minutes | Leave it on for safety. |
| Alarm clocks | The alarm clock even in silence mode | Make sure to |
| Notification of events | Calendar reminder sound | At your discretion. |
Check if you have a restriction on notifications from specific applications. The exclusion section often has an "Applications" item where you can choose which programs have the right to bother you. If the messenger is not on the list of allowed, you will not hear the message, even if the "Do Not Disturb" mode seems to be off but configured incorrectly.
Management through the Security app
In the Xiaomi ecosystem, the system application Security plays a key role, combining antivirus, memory cleaning and performance settings, including audio profile management. Sometimes the audio settings in the main menu and in the Security app can conflict or duplicate each other.
Run the Security app and find the Do Not Disturb section (often in the toolbox or the More menu) and it shows the current mode status. If the activity indicator is on, click on it to turn it off. This app also shows the mode usage statistics.
Why are the settings in “Security” and “Settings” different?
Inside this tool, you can also find a history of blocking, and if you missed an important call, check the log in the Security app, which can store information that the call was blocked by a Do Not Disturb profile, even if the phone was performing normally.
Solving problems with freeze mode on the lock screen
One common problem is when Do Not Disturb mode is not turned off by standard methods or is spontaneously turned on on the lock screen, which often happens after a HyperOS firmware update or when you install "curve" themes, in which case resetting the audio profile settings helps.
Try to do the following: turn on the Do Not Disturb mode manually, wait 10 seconds, then turn it off. Then restart the device. If the problem persists, check if the Pocket mode is activated. The proximity sensor may misidentify the phone's position in your pocket and turn on silence.
⚠️ Note: If the Do Not Disturb mode is activated by itself when the charger is connected, check the script settings. MIUI there is an automation feature that can be accidentally activated for the Connect to Charge event».
It’s also worth checking the Digital Well-Being settings. Some versions of Android installed on top of MIUI have Sleep Time or Focus features that forcefully turn on Silence Mode. You can find them in Settings → Digital Well-Being → Sleep Mode.
Resetting sound settings and additional solutions
If none of the above methods worked, the configuration file of the sound subsystem may have been damaged, in which case resetting all the audio settings to factory values will help, and this will not delete your personal data, photos or contacts, but will return all calls and notifications to their original state.
To do this, go to Settings → Advanced Settings → Restore and Reset. Select Reset all settings, carefully reading the description so as not to confuse it with a full factory reset (which deletes data).
💡
Before resetting, take screenshots of important Wi-Fi and Bluetooth configurations, as they will have to be re-entered after the procedure.
In extreme cases, if the problem is caused by a system bug of a particular version of MIUI, cleaning the cache of the system application Settings can help. Go to Settings → Apps → All Apps → Settings → Memory → Clear cache. Don’t confuse it with cleaning data, although in most cases it is safe, it is better to start with the cache.
💡
Comprehensive approach to the solution: if simply turning off the slider does not help, consistently check schedules, exceptions and the Pocket mode - in 90% of cases, the problem lies in one of these points.
