Xiaomi and Redmi series smartphones are famous for their functionality, but sometimes too much settings leads to unexpected situations. One of the most common problems users face is suddenly turning on the Do Not Disturb mode. The phone stops ringing, notifications do not appear, and the screen does not light up when an incoming call. This can cause panic, especially if you are waiting for an important call or using your alarm phone.
Fortunately, MIUI and the new HyperOS have a logical way of doing this, and there are a number of ways to get it back to normal. In this article, we’ll go into detail on how to disable the feature, explain how to set up contact exceptions, and look at the reasons why your phone may be silent even after you try to change settings.
You can quickly reconnect with the outside world using simple actions in the settings menu or through the notification curtain, and we will also address the complex cases where a software failure blocks sound, and tell you how to correctly diagnose a problem without losing important data.
Quick shutdown through notification curtain and sidebar
The easiest and fastest way to remove the Do Not Disturb mode on Xiaomi is to use the Control Panel, which works 90% of the time when the feature was turned on by accident, and you need to unlock the smartphone screen and swipe from top to bottom to open the curtain.
At the top of the menu that opens, you'll see a number of icons that represent different functions: Wi-Fi, Bluetooth, flashlight, and others, and you'll need to find a crescent icon, if it's illuminated (usually in blue or orange), then the mode is active. Just click on it once, so that the icon goes out and the mode is deactivated.
Sometimes the icon can be hidden in the second page of the Quick Settings menu, in which case you need to swipe the panel left or right to find hidden items. If you can't find the icon, try clicking on the edit button (usually a pencil or three dots) to add the "Do Not Disturb" label to the main screen of the panel.
It's important to understand that this method only disables the current status of the function, but does not change its settings. If you have an automatic turn on schedule, after a while, the mode can be activated again, so after manually turning off, you should check the automation settings.
Deep customization via the "Do Not Disturb" menu
If you just switch the slider doesn't work, or you need more subtle control, you should go to system settings, and you've got all the parameters that affect how a smartphone behaves in silence, and the path to them may vary slightly depending on the version of MIUI, but the overall logic remains the same.
To start, open the Settings app and find the Sound and Vibration section, and inside this menu you'll see the Do Not Disturb item, and you click on it, you'll be taken to the Settings control center, and that's where you can completely prevent the system from enabling this mode or configuring it.
Inside the menu, you'll see the "Enable" switch that duplicates the function from the curtain. Below are the schedule settings. Often users forget that they have activated the "23:00 to 07:00" rule, and wonder why the phone is silent at night or early in the morning. Make sure that all the switches in the "Schedule" block are turned off if you don't want automatic activation.
☑️ Checking the settings "Do not disturb»
The exceptions section deserves special attention. Even if the Do Not Disturb mode is active, you can allow calls from favorite contacts or re-calls. In the settings menu, find the "Exceptions" or "Allow calls from" option. Here you can choose the "All Contacts" or "Favorites" option to avoid missing a critical call even in silence.
Scheduling and automation management
One of the most useful, but sometimes confusing, features is that it automatically switches on schedule, and it allows you to set the time when your phone will go into silent mode, which is convenient for sleeping, but can be a problem if you have a shift schedule or if you forget to set up.
To manage your schedule, go to Settings → Sound and Vibration → Don’t Disturb → Schedule. Here you’ll see a list of active rules. If you see an active rule like Sleep Time, click on it. You can change the start and end times or completely delete the rule by clicking on the basket or activity switch.
There is also a smart schedule feature that can be enabled based on your habits or calendar events. In newer versions of HyperOS, algorithms can suggest turning on mode if sensors detect you're asleep. Turn off the Smart Schedule option if you want to fully control the process manually.
What to do if the schedule is not switched off?
Also worth mentioning is the Events feature.The phone can go into silent mode if the calendar has a "Meeting" or "Dream" mark. Check the calendar settings and event synchronization to make sure they don't block the sound at the wrong time.
Set up exceptions for calls and messages
Do Not Disturb mode doesn't necessarily mean complete isolation. You can set the system up to let certain people call you or call you again, and this is especially true for parents who want to sleep but are afraid to miss a child's call, or for the staff on duty.
In the exclusion menu you will find the following important options:
- 📞 Repeated calls: If the same number rings twice in 3 minutes, the second call will pass with sound.
- 👥 Favorite Contacts: You can create a Favorites list in your phone book and only allow calls from there.
- 💬 Messages: You can allow notifications from certain applications, such as instant messengers, even when the silence mode is active.
To set up your favorite contacts, open the Contacts app, find the right person, click on their name, and select the Add to Favorites option (usually indicated by an asterisk).
💡
Use Do Not Disturb mode with focus exceptions. Allow calls only from colleagues while working, blocking social media and personal contacts to increase productivity.
Remember that exception settings may reset after a system update.Check this section periodically, especially after major MIUI updates, to make sure important contacts continue to take priority.
Problems with alarm clock in silence mode
One of the most common fears users have is not to wake up in the morning because of the “Do Not Disturb” mode, which is said to turn off the alarm clock, but in reality Xiaomi and Android are different, and the alarm system should sound even when the silent mode is active.
However, there are exceptions. If you use a third-party alarm app, it may not have the necessary permissions. Xiaomi or Google's standard Watch app takes precedence and ignores Do Not Disturb mode. Make sure the alarm clock volume is not turned to zero separate from the total volume.
The table below compares the behavior of different audio signals in Do Not Disturb mode:
| Type of sound | Do Not Disturb Behavior | Can I change it? |
|---|---|---|
| System alarm | It always sounds. | No (default) |
| Incoming call | Without sound, the screen doesn't burn. | Yes (with exceptions) |
| Notification of the messenger | No sound, vibration only (if permitted) | Yes (via app settings) |
| Timer. | It always sounds. | No. |
If your alarm is silent, check if the Watch app itself has a special mode or Night Mode that may conflict with system settings. Also make sure the phone is not turned off and has a battery charge.
Resetting sound settings and solving problems
What if you tried all the methods, but the phone still behaves strangely? For example, the crescent icon burns, but you can't remove it, or the settings don't save, in which case you may need to intervene more deeply.
The first step should always be a banal but effective reboot, which cleans temporary files and resets the system's hanging processes, which can block the change in audio settings. If that doesn't work, try resetting the network and audio settings.
To do this, go to Settings → Advanced Settings → Restore and Reset. Select Reset Wi-Fi, Mobile Networks and Bluetooth. This action will not delete your personal data, photos or contacts, but will return network settings and some system settings to factory values.
💡
If the software methods don't work, the problem may be hardware. Check the physical volume buttons - if one of them goes off, it can constantly turn on or off the silence mode.
As a last resort, if the problem only manifests itself in one application (for example, no notifications from WhatsApp), try to clear the cache of this application or reinstall it. Often, a conflict of software versions and applications causes notifications to malfunction.
