Modern Xiaomi smartphones come with a variety of productivity features, including Do Not Disturb mode, which allows you to temporarily block incoming calls, messages and system notifications, creating the perfect atmosphere for work or sleep. However, users often face a situation where the feature is activated accidentally or does not turn off in the usual way, which leads to the skip of important calls.
Understanding the mechanisms of MIUI and HyperOS is essential for managing notifications properly. In this article, we will explore all the ways to deactivate mode, adjust schedules and exceptions, and consider the reasons why the phone can remain silent even after the function is turned off. On Xiaomi smartphones with the shell of MIUI 12 and later, the notification blocking algorithm takes precedence over standard calls.
There are several levels of locking, from simply turning off the slider in the curtain to deep settings in the system menu. If you missed an important call from a doctor or courier, you should check not only the main switch, but also related settings, such as Silence or Locking Repeat Calls.
Quick shutdown through the control panel and curtain
The most obvious and quick way to get your phone back to normal is to use the control panel. Most Xiaomi and Redmi devices just swipe down from the top right or left corner of the screen to open the control center, and here are the main switches for wireless interfaces and system functions.
You need to find an icon that represents a crescent. If it's illuminated, it means that mode is active. Press it once to deactivate the function. In some versions of the MIUI shell, if you press this icon for a long time, you open an extended settings menu where you can immediately go to the exception options.
If you don't see the button you want in the quick access, it's probably hidden. Editing the panel allows you to add or remove shortcuts for quick access, and this is especially true for users who rarely use the feature and have taken it out of sight.
- 🌙 Swipe down to open the control center and find the crescent icon.
- ⚙️ Click on the icon to switch the state of the mode to “Off».
- 📱 Make sure the status bar is cleared of the notification lock icon.
Sometimes the system can stick and the visual display of the mode does not correspond to the real state, in which case it helps simply to restart the device or re-energize and turn off the function, which is a standard procedure for resetting software errors of the interface.
Deep customization through the system menu
To get more detailed lock management, you need to go into the basic settings of the smartphone. The path may vary slightly depending on the version of the operating system, but the logic remains the same for all devices of the brand, and here you get complete control over the behavior of the phone in different situations.
Go to Settings → Sound and Vibration → Don’t Disturb. This is where all the controls are. You can see the Turn on switch that duplicates the function from the curtain, but below are the finer adjustment tools.
☑️ Checking the settings of the mode
In this section, it's important to pay attention to the "Silence" item, which, if activated, will block sounds from even selected contacts unless they are specifically excluded, a critical parameter that is often overlooked when diagnosing sound problems.
⚠️ Warning: Activating the Silence item can completely drown out the phone, ignoring the media volume settings and call.
You can also set the system's response to alarms here, and by default, they should even sound in Do Not Disturb mode, but you can check this setting. Make sure the alarm switch is in the active position.
Scheduling and automation management
One of the most useful, but sometimes annoying, features is to automatically turn on schedule, and the smartphone can switch to lock mode at certain times of the day, such as at night or during meetings, if it is configured in the calendar.
In the Do Not Disturb mode settings menu, look for the schedule section, and there may be active profiles like "Sleep Time" or "Meeting." If the phone is silent at unexpected times, it's likely that's where it's going.
You can set up multiple time slots, like one for night time, one for weekends, and Android allows you to flexibly manage the days of the week by choosing specific dates to activate the feature.
- 🕒 Click on “Add Schedule” to create a new time slot.
- 📅 Select the days of the week and set the start and end times for the action.
- 🔇 Determine whether to include the “Silence” mode during this period.
How does a smart schedule work?
Turning off the automation will give you full control of your audio profiles, and if you're not using your schedule, it's best to completely remove the time slots created to avoid confusion in the future, ensuring that your phone doesn't go silent at the most inopportune time.
Set up exceptions for contacts and applications
Do Not Disturb mode doesn't necessarily mean complete isolation. You can set exceptions to allow silence to be interrupted for certain people or applications. It's the perfect balance between concentration and availability for emergencies.
In the "Exceptions" section, you can choose who you are allowed to call, and options are available: "Nobody", "Favourites", "All Contacts" or "All." Choosing the "Favorites" option requires you to add important numbers to the asterisk contact list first.
You can also set up repeat calls, and if the same number calls you twice in 15 minutes, the second call will pass, even if the caller is not on the favorites list, which is a useful feature in case of an emergency.
| Exclusion parameter | Description of action | Recommendation |
|---|---|---|
| Calls. | Allow calls from a select few or all | Leave "Favorites" for important contacts |
| Communications | Allow notifications from messengers | Turn on for work chats. |
| Repeated calls | Missing the second call in 15 minutes | It is recommended to keep on |
| Alarm clocks | The sound of the alarm clock in quiet mode | Make sure to |
💡
Properly configured exceptions allow you to stay in touch with loved ones, maintaining protection from advertising spam and unnecessary notifications.
Be sure to check the settings of specific applications. Some messengers may have their own internal Do Not Disturb settings, which work independently of the system settings. Check the settings inside Telegram, WhatsApp or Viber.
Features of the mode in game optimization
Special attention deserves the game mode, which is often confused with the usual “Do not disturb”. On Xiaomi smartphones there is a function “Game Turbo” or “Accelerate Games”, which when you start games automatically blocks notifications and calls so as not to interrupt the process.
If the phone is silent only during games, check the settings of the game accelerator. Inside the game you can call a floating menu (usually a swipe from the corner of the screen) and find the notification settings, you can allow calls or disable the lock completely.
Often users forget that they have activated Flight Mode inside the game accelerator to reduce ping, and this also blocks all incoming connections.
- 🎮 Start the game and call the accelerator menu swipe.
- 🔌 Check if the “Do Not Disturb” mode is activated specifically for games.
- 📶 Make sure that flight mode is not forced into the game profile.
This is a separate layer of protection that works on top of the system settings MIUI. Understanding this hierarchy will help you quickly find the reason for the lack of sound in gaming applications.
Problem Solving: If the regime is not switched off
There are times when the slider in the settings does not respond to the presses, or the mode turns on itself immediately after turning off, this may indicate a software failure, application conflict, or damage to system files.
The first step should always be to restart the device, which clears RAM and restarts the system services responsible for notifications, and if that doesn't work, try running the phone in Safe Mode to eliminate the impact of third-party apps.
If the problem persists, you may need to reset your network settings or even reset completely to factory settings. Before drastic measures, try clearing the cache of the Settings and Phone system application.
⚠️ Warning: Resetting to factory settings will delete all your data. be sure to back up before this procedure.
In rare cases, the cause may be a sensor malfunction or a software bug of a particular firmware version, in which case it is worth checking for system updates or contacting the service center if the problem is hardware in nature.
