Xiaomi’s current MIUI or HyperOS smartphone is a powerful communication tool that can unfortunately break the silence at the most inopportune moment. Loud SMS notifications often cause discomfort during meetings, in cinemas or at night when absolute silence is required. Users often wonder how to effectively and quickly turn off the sound for text messages without affecting other important notifications.
In this article, we will take a closer look at all the available audible alert management techniques, and we will look at standard system settings, the capabilities of the built-in messaging app, and more advanced ways through Do Not Disturb and Audio Profile modes, which will allow you to flexibly manage your device’s acoustic space.
Turning off SMS on Xiaomi is not just a volume removal, but a fine-tuning of the notification system. Android, which runs the Chinese brand’s smartphones, provides ample opportunities for personalization. You can customize separate rules for contacts, create exceptions or completely drown out message types, while still being able to see them in the notification curtain.
Basic Volume and Sound Profiles setting
The first and most obvious way to control sound is to use physical buttons or quick setup menus. However, many users are unaware that MIUI has a volume split into multiple channels. By pressing the audio button, you can switch between media, call and notifications, and that's the last parameter that's responsible for the sound of incoming SMS.
For more detailed control, you need to go to the system menu, where you can not only turn down the volume, but also choose a specific sound profile. The standard General profile reproduces all the sounds, while No Sound turns them off completely. There is also a Vibration Only profile, which replaces the melody with a tactile response. This is convenient when the phone is in your pocket or bag.
- 🔊 Press the volume button and select the gear icon to go to the advanced settings.
- 🔇 Switch the “Notification Sound” slider to the minimum position or select “No Sound” mode».
- ⚙️ Use the Settings menu → Sound and vibration for fine calibration of levels.
Importantly, the global reduction in notification volume will affect not only SMS messages, but also messaging messages, emails and system addresses. If your goal is silence from operator messages only, this method may be too radical, in which case you should use a customized application setup, which will be discussed below.
Individual setting of the application "Messages"
The most accurate method is to change the parameters inside the messaging app itself. Xiaomi smartphones use Google's Messages app or Mi Messaging's own design by default. The interface may vary slightly depending on the Android version and regional firmware, but the logic remains the same.
To turn off the sound, open the app and find the settings menu, usually hidden behind three dots in the corner of the screen or the gear icon. You're interested in the Notifications or Sound and Vibration section, where you can turn off the sound completely for incoming SMS, leaving the visual display in the status bar, which allows you to see missed messages without creating noise pollution.
☑️ Algorithm of turning off sound in the application
Some versions of the shell include Notification Categories, which allows you to customize the sound for SMS, bank messages, and personal correspondence, so that important messages from loved ones are accompanied by sound, and mailings from stores come silently, which requires more deep tuning, but gives maximum comfort.
⚠️ Note: When turning off the sound in the app settings, make sure you don’t turn off critical notifications, such as confirmation codes for logging into banking apps.
Use of the "Do Not Disturb" mode
Do Not Disturb (DND) is a powerful tool built into Android that allows you to create complex scripts to block sounds. Unlike simple silent mode, DND allows you to create “whitelists” of contacts and applications. You can set the phone to keep it silent on all texts except those from favorite contacts.
To activate this mode, go to Settings → Sound and Vibration → Don’t Disturb. You can set a schedule to automatically go quiet at night or while you’re working. In the Apps or Notifications section, you can prevent interruptions from the Messages app, leaving the option to call, which is the perfect balance between accessibility and silence.
Mode control is also available via a notification curtain.A long tap on the Do Not Disturb icon will open a quick settings menu where you can quickly activate the Nothing or Alarms Only rule.The HyperOS system also offers smart scripts that can turn on this mode automatically when you're in a theater (determined by geolocation or Wi-Fi connection).
- 🌙 Set up automatic switching on schedule for night time.
- 📞 Add important contacts to the exclusion list so that their SMS and calls pass.
- 🚫 Select the option “Hide content” so that the text does not flash on the lock screen.
💡
Use the voice assistant to turn on the mode quickly. Just say "Xi Xiao Ai, turn on Do Not Disturb mode," and the phone will stop.
Set up notifications for specific contacts
If the problem of loud texting only affects certain numbers, or vice versa, you want to hear only a select few, use the notification setting for contacts. In the standard Xiaomi phone book, you can assign each contact a custom tune or choose the "No Sound" option, which works for both calls and messages if you use a standard application.
Open a contact, click on the edit button or three dots, and find the default melody or notification sound. By choosing No Sound, you are guaranteed not to hear any alerts from that subscriber, which is especially true for group chats or contacts that generate a lot of advertising spam.
| Type of setup | Where to find out. | The effect | Difficulty |
|---|---|---|---|
| Global volume | Body buttons/Stork | Turns off the sound of all notifications | Low. |
| Application settings | Annex “Messages” | Only SMS is turning off the sound. | Medium |
| DND regime | System settings | Flexible filtering by time and contact | Tall. |
| Contact setting | Contacts/Telephone | Individual silence for the room | Medium |
Remember, customized contact settings can override global settings, but not always. If you have a "Do Not Disturb" mode enabled with a select few resolution, then the "No Sound" setting for a particular contact can be ignored if it's not on your favorites list. Always prioritize settings.
Management through a special options menu
For people with hearing impairments or those who want absolute control, there is a feature menu on Android, and while the main function is to help people with disabilities, you can find additional audio controls, such as boosting vibrations or turning on visual indications instead of sound.
In Settings → Advanced Settings → Special features can be found options like “Sound Monitoring” or “Visual Alerts”. Activating visual alerts causes the smartphone screen to flash when the SMS comes, even if the sound is completely off, this ensures that you do not miss an important message in a noisy place where the sound is still not heard.
The Secret Function of the Engineering Menu
And there's also a feature called "Audibility Improvement," which can actually amplify sounds, so make sure it's turned off if you want to keep quiet, and sometimes people accidentally activate those features, thinking they're standard audio settings, and wonder why the phone sounds different.
Third-party applications for managing notifications
If you don't have enough MIUI built-in tools, Google Play offers a lot of management apps, and programs like Notification Manager or MacroDroid can create complex scenarios, such as setting up a rule: "If you get a text message from your bank after 20:00, turn on the vibration and turn off the screen."
Using such applications requires broad permissions to access notifications, so that the program can read and apply rules to incoming messages, and be careful to choose only trusted applications with high ratings, so as not to share your personal data with third parties.
- 🤖 MacroDroid allows you to create macros: If it is 23:00, turn off the sound of SMS».
- 🔒 NotifyBuddy helps filter notifications and hide their content on a locked screen.
- 📱 Tasker – Professional Automation Tool Requiring Customization Skills.
⚠️ Warning: Installing third-party notification managers may conflict with Xiaomi’s system settings, causing delays in receiving messages or increased battery consumption.
Problem Solving and FAQ
Sometimes users are faced with a situation where the settings are down and the sound of the SMS turns on on itself, this can be due to system updates, malfunctions in the Messages application or conflict with the themes of the design, in such cases, it is recommended to clear the app cache or reset the sound settings to the factory.
It's also worth checking if you have a custom theme installed. Some themes downloaded from Themes store may have their own sound profiles that overlap the system ones. Switching to a standard theme often solves the problem of "phantom" sounds.

💡
The optimal strategy is to combine the “Do Not Disturb” mode on a schedule and individually adjust the volume of notifications for maximum comfort.
In conclusion, SMS management on Xiaomi is a once-in-a-lifetime process that is set up correctly. Using a combination of system profiles, app settings and smart modes, you will turn your smartphone from a noise source into a docile tool. Remember to check system updates periodically, as Xiaomi is constantly improving the notification algorithms in new versions of HyperOS.
