Xiaomi’s current smartphones, which are powered by MIUI or HyperOS, offer users the most personalization options, but despite their rich functionality, many owners have difficulty changing the standard melodic signal of incoming messages, especially when standard sound is blended into system notifications or annoyed with its monotony.
Often, users are unaware that audio profile management in the Xiaomi ecosystem is divided into several levels: system settings, parameters of a particular messenger application, and global sound profiles, understanding this hierarchy is the key to successfully customize your device.
In this article, we will discuss in detail all the ways to install the desired melody on SMS. We will consider both the regular system tools and the nuances of third-party applications, such as Google Messages or Mi Messages.
System settings of sound notifications
The first and most logical step is to go to the basic operating system settings, and that's where the default tone is set for all applications that don't have their own priority audio settings, and to get into this section, you have to open the Settings app and find the Sound and Vibration item.
In the menu that opens, you'll see a lot of sliders and switches, and we're interested in the "Additional settings" section or the immediately visible "Notification Sound" item, and if you click on it, the system will tell you to choose one of the preset tunes, and you can adjust the overall volume of the notifications without affecting the volume of the call or the media.
But it's important to understand that changing this parameter globally changes the sound for all applications that use the system standard, and if you want SMS to sound different than emails or social media notifications, that step won't be enough, and that requires fine-tuning through specific applications.
💡
The global notification sound setting in the Sound & Vibration menu changes the default tone for all applications that don’t have their own custom settings.
It's worth noting that new versions of HyperOS may have slightly different interfaces, but the logic remains the same. It's a way to unify control, but it allows for detailed control. Remember that the sound you choose must be loud and distinct enough to be heard in a noisy room.
Customization of sound in the standard application Messages
If you don’t like the global setting, you need to move to an individual configuration of the application for SMS. On Xiaomi smartphones, different applications can be installed for working with text messages: the standard Mi Messages or Google Messages. The algorithm for actions for them will vary.
For Mi Messages users (blue envelope icon), the path is as follows: open the app, click on the three dots in the top right corner and select Settings. Next, go to Notifications and find the Sound option, where you can select any tune from the system list or download yours.
In the case of Google Messages (blue bubble with letters), the logic is a little different: click on the profile avatar in the corner, select Message Settings, then Notifications. Make sure the switch is activated, and click on Sound. The system will offer a standard set or the ability to select a file from the device's memory.
Special attention should be paid to access rights. If an application does not have permission to access media files or storage, it may not see your downloaded tunes. Check permissions under Apps -> All Apps -> Messages -> Permissions.
How to set your tune on SMS
The standard audio set provided by the manufacturer is often scanty or uninteresting. Fortunately, Xiaomi allows you to use any audio files in MP3, OGG or WAV format as a signal.
Once you download a melody, the installation process depends on the shell version. In some cases, it is enough to open a file through the explorer, click on it and select "Use as a notification signal." If this option is not available, follow the algorithm: go to the sound settings, select "Notification Sound", scroll the list to the bottom and click "Add" or "Select from files."
💡
To display the signals correctly in the list, create a folder called Notifications at the root of internal memory and place your own memory there. mp3 file.
It is important to keep track duration. The optimal sound time of the notification is from 2 to 5 seconds. Too long songs can break in the middle of a word when the second message arrives or annoy others. Also make sure that the file is not copyrighted by DRM, otherwise the system will not be able to reproduce it.
If you use a computer to transfer files, make sure they are copied to internal memory, not to the computer. SD-Map, as modern versions of Android can restrict applications from external drives to improve security.
Individual settings for different contacts
One of the most useful features in Xiaomi smartphones is the ability to assign unique sounds to specific senders, which allows you to instantly know who wrote to you without even looking at the screen, a feature that is especially useful for messages from close relatives or important work contacts.
To set up, open the dialog with the desired contact in the Messages app. Click on three dots (menu) and select Details or Contact Information. In the menu that opens, find Sound or Special Notification, and here you can select a unique track for that person.
Note that this function only works if the contact is saved in the phone book. For unknown numbers, you cannot set a customized sound due to privacy and system architecture reasons, and the setting may not apply if the contact has blocked notifications in the system settings.
☑️ Customization of sound for contact
Using this feature helps to avoid missing an important message in a noisy environment, for example, you can set a quiet but ringing signal for messages from children to hear them even when the phone is down.
Set up notification channels in Android
Starting with Android 8.0, the system uses the Notification Channels mechanism, which means that within the same application (for example, Messages), there can be different types of notifications: New Messages, Sends, Delivery Errors, etc. Each channel can be set to its own sound.
To access these settings, go to Settings on your phone, select Apps -> All Apps. Find your SMS app in the list. Click Notifications. You'll see a list of categories (channels). Click on category text (like New Messages) instead of the switch.
A detailed menu will open where you can change sound, importance (affects pop-up and sound), vibration and LED behavior. Make sure that importance is set to High or Urgent if you want to be sure you hear the signal even in Do Not Disturb mode (if permitted).
| Channel parameter | Description of the impact | Recommendation for the AMS |
|---|---|---|
| Importance | Determines whether there will be a sound and a pop-up | High (to hear) |
| Sound. | playback melody | Loud and different from others |
| Vibration. | Vibration pattern | Activate for soundless mode |
| Light indicator | LED flashing | Insert for night time |
This is the deepest level of customization that rewrites the global settings, and if you put "No Sound" on it, no other settings can help, because the phone will be silent, so checking the notification channels is the first step in diagnosing problems.
Do Not Disturb Mode and Sound Profiles
A common reason for not having an SMS sound is an activated Do Not Disturb mode or a specific sound profile, and Xiaomi uses a side menu or settings in the Sound and Vibration section to check if you have a No Sound or Vibration profile.
Do Not Disturb mode can block all sounds except for selected contacts. If you are waiting for an important message, add the sender number to the exclusion list. To do this, go to the Do Not Disturb mode settings -> Allow notifications from -> Calls and messages -> Selected contacts only.
⚠️ Warning: If you have Do Not Disturb mode enabled with full lock, the SMS sound will not play even if the app settings have a loud melody. Always check the profile status in the notification curtain.
There's also a Pocket Mode feature, or proximity sensors, that can mistakenly jam the sound if the phone is in the bag. Make sure the speaker isn't covered by a case or foreign objects.
Sound problems and their solution
There are times when all the settings are correct, but the sound never comes up. One of the common causes is third-party launcher conflicts or design themes; some "heavy" themes may not handle system sounds properly. Try switching to a standard theme for verification.
Another reason is the overcrowded cache of the Messages app or the Android System service. Cache cleaning often solves the problem of stuck settings. Go to Settings -> Apps -> All Apps, find the desired application, click Clear -> Clear cache.
Hidden Developer Settings
If nothing works, check if the headset is connected via Bluetooth.The phone may try to display the notification sound on headphones that are currently in another room or off. Turn off Bluetooth temporarily for diagnosis.
⚠️ Note: When clearing the data (not only the cache) of the Messages application, the correspondence history may be deleted if it is not synchronized with the cloud or stored on the Internet. SIM-Be careful when selecting the item "Clear».
