Smartphone personalization is not just a fashion homage, but a way to instantly identify incoming messages without having to look at the screen. Owners of Xiaomi, Redmi and Poco devices often face a situation where the standard sound of notifications merges with the system signals of other applications. Changing the melody on SMS helps to distinguish important messages from operators or banking services among information noise.
The process of installing your own audio file in shells MIUI The new HyperOS has its own features, different from pure Android, and security and battery optimization sometimes hide the necessary settings, requiring the user to know the exact paths of navigation. In this article, we will discuss all current methods of sound replacement, including installing your own sound. MP3-tracks and fine-tuning for individual contacts.
Preparation of an audio file and file system
Before you start setting up your system, you need to make sure that your audio file is properly prepared and placed in the device memory. Android file system requires a certain folder structure to correctly display media files in the system menu. If the file is in an arbitrary download folder, the standard conductor may not see it when selecting a ringtone.
The best solution is to move the music file to the root directory or a special folder Ringtones. For this you can use the built-in Explorer application or third-party file managers such as Total Commander or FX File Explorer. It is important that the file format is compatible with the system, the most universal standard is MP3 with a bit rate of no higher than 320 kbit / s.
In some cases, the system may not scan new files immediately after they are uploaded. If you moved a track but didn't find it on the list, try restarting the device or clearing the cache of the Music app. It's also worth checking if the file is hidden by system attributes, although this is rare on modern Android versions.
💡
Use audio files that are no longer than 30 seconds long for notifications so that they do not get cut off abruptly and take up extra space in the system cache.
Standard installation through message settings
The most direct and reliable way to change the notification sound is to refer to the native settings of the Messages app. Xiaomi smartphones use either the standard Google Messages app or the proprietary MIUI Messaging shell by default. The algorithm of actions may vary slightly depending on the firmware version, but the overall logic remains the same.
You open the messaging app and go to the control menu, which is usually hidden under the icon with three dots or a gear in the corner of the screen, and then you should find the option "Settings" and then the section "Notifications" or "Sounds and vibrations." This is where the audio file is associated with the event receiving the SMS.
☑️ Algorithm of sound setting
Once you select Sound, you'll see a system player, where you often have a "All Sounds" tab or a plus button at the top of the screen, and you'll be taken to the file manager, where you can select a track you've previously prepared, and if the standard path doesn't lead to success, your device may need an extended procedure through global settings.
⚠️ Note: In new versions of HyperOS, access to the file system may be restricted to permissions. When you first select a file, the system will request permission to access media files - this must be confirmed, otherwise the track list will remain empty.
Customization through the global sound menu
If the message app doesn't find the right option, you can use the smartphone's global settings, which is a universal method that allows you to control the sound circuits for all system events at once. Go to the main menu settings and select the Sound and Vibration section.
In the menu that opens, scroll down to “Additional Settings” or immediately look for “Notification Sound.” Depending on the firmware region (Global, China, EEA), the names of the items can vary. Here you will see a list of system sounds, including alarm clock, lock and, in fact, SMS.
Selecting the Notification Sound will put you in a similar track selection menu, and the advantage of this method is that it compulsorily prioritizes the selected sound for all applications using the system's standard notification channel, ensuring that the SMS is not lost even if the application itself has a setup failure.
It is worth noting that the global setting can be overwritten by individual application settings. If the sound in the SMS has not changed after installation through the main menu, check whether the message application itself should not have the “Use the default sound” tick that you need to remove.
Install a unique sound for a specific contact
Often, you need to hear different tunes for different senders, such as important messages from work should be loud and Distinctly, and mailings from stores can be left quiet or silent. To implement this feature, Xiaomi uses a bundle of the Contacts and Messages app.
Open the Contacts app and find the person you want to call, click on their name to open the card, and select Change (usually a pencil icon) and find the Melody or Rington section in the field list, and you can select a separate file for that person.
But this is primarily a way to make incoming calls work, and in order for it to work for SMS, you need the message app to support contact-association. In Google Messages, it works automatically: if you have your phone book sound set for the contact, it will also apply to messages. In MIUI Messaging, you sometimes need to enter a conversation with a specific person, click three dots in the corner, and select Notification Sound if you have it.
| Type of setup | Priority | Where it changes | Features |
|---|---|---|---|
| Global | Low. | Phone settings | Changes for everyone at once. |
| In the annex | Medium. | Message settings | It covers the global |
| For contact | High-pitched | Contact card | Works only for a select few. |
| Inside the dialogue | Maximum | Chat menu | Only for specific correspondence |
It is important to understand the hierarchy of settings: customization for contact will always take priority over the overall configuration of the application, which allows you to create a flexible alert system where you immediately know who is texting you, even without taking the phone out of your pocket.
Use of themes and theme store
Xiaomi's ecosystem offers a unique customization tool called the Themes app, where you can find not only wallpaper, but also ready-made sound packages designed specifically for the shell interface, which is a great option for those who do not want to search and crop music themselves.
Run the Themes app on your desktop. At the bottom of the screen, find the Profile tab or the person icon, then go to the Ringtones or Sounds section. The directory features a variety of free packs, from classic tunes to modern electronic tracks.
After downloading the set you like, it will automatically apply to all system notifications, including SMS. The advantage of the method is that the sounds in the themes are already optimized for length and volume, which eliminates problems with a sharp break of the melody or too quiet playback.
Theme store secrets
However, be careful: installing a new theme can change not only sounds, but also icons and fonts. When installing a sound package, read the description carefully so that you do not accidentally replace the entire visual style of the interface, if you did not plan to.
Reproduction problems and their solution
Despite the simplicity of the procedure, users sometimes face situations where the set sound is not played or the SMS comes in silent, most often due to the aggressive MIUI energy saving system, which can “sleep” the background processes of media processing.
The first thing to check is Do Not Disturb or Silent Mode. Make sure that the Sound and Vibration settings do not activate notification restrictions. Also check the volume slider specifically for media files and notifications, as they are adjustable separately from the volume of the call.
The second common problem is the file format. If you downloaded a track in FLAC, WAV or M4A, the system may ignore it when trying to install it on SMS. Converting to a standard MP3 (128-320 kbps) solves 99% of these problems.
⚠️ Note: If you use third-party launchers or memory cleanup applications, they may block the system messaging service from accessing the media library. Add the Messages app to the exclusion list (“No Limits”) in the battery settings.
Also worth mentioning is the application conflict: If you have multiple SMS programs installed (e.g., standard and third-party), they may be in conflict over the right to be the default application. Go to Settings → Applications → Application Management → Three dots → Default apps and make sure the program you want is selected.
