Xiaomi’s smartphones, including the flagship Mi 9, are not only famous for their performance but also for the flexibility of customizing the MIUI interface. However, many users face difficulties in trying to personalize the audio, since the standard shell has its own features of working with the file system.
The process of replacing the ringtone with the Xiaomi Mi 9 can seem confusing due to aggressive system optimization and hidden folders. Unlike pure Android, there are nuances of placing files at the root of internal memory. Understanding the structure of directories will avoid situations where the file is downloaded, but does not appear in the list of available tunes.
In this article, we’ll look at all the current ways to install audio files on calls, messages, and notifications. You’ll learn how to properly prepare tracks, what formats the system supports, and how to circumvent restrictions if the standard method doesn’t work. Follow the step-by-step instructions to make your Mi 9 sound exactly the way you want it to.
Preparation of audio file and format check
The first step before installing is to check the audio file itself. The MIUI system installed on the Xiaomi Mi 9 works correctly with popular compression formats, but for system ringtones there are optimal parameters. Most users try to install tracks in MP3 format, which is the most versatile solution for this model.
It is important to consider not only the file extension, but also its bitrate and duration. Too long compositions can be cropped by the system or play incorrectly at the time of an incoming call. It is recommended to use files lasting up to 30-40 seconds for calls so that the melody has time to play a full cycle before the subscriber responds.
If your file has a non-standard extension, for example FLAC or WAV High quality, the system can ignore it in the ringtones list, in which case you need to pre-convert the track. DRM-protection, which is often found in tracks downloaded from streaming services.
- 🎵 Optimal format: MP3 bitrate 128-320 quid.
- ⏱️ Recommended duration: 15 to 40 seconds.
- 📁 The file name is better written in Latin for maximum compatibility.
- 🚫 Avoid files with DRM-protection from paid subscriptions.
💡
Use online converters or editorial apps to crop the track to the desired length before loading into your phone’s memory.
Standard method through the settings menu
The easiest way to set a melody is to use the built-in shell functionality, and you'll need a downloaded file that the system can recognize. Go to your smartphone's Settings section and find Sounds and Vibration, and that's where all the audio settings are concentrated.
In the menu that opens, select the category you want to change: “Call Melody”, “Notification Sound” or “Alarm Sound”. The system will offer a list of standard compositions, but at the bottom of the screen there is usually a local file select button. On the Xiaomi Mi 9, this interface can be called “All tunes” or have a plus icon.
When you click on the button, you'll open a file manager or a special audio player in the system. You'll need to navigating by folder to find the downloaded track. If the file doesn't show up, check which folder it's in, sometimes the system defaults to the wrong directory where you saved the music.

Manual placement of files in the file system
If the standard method does not allow you to select the desired track or the file is simply not visible in the list, you need to use a manual placement method. This is the most reliable way for the Xiaomi Mi 9, ensuring that the system detects the audio file. You will need any file manager, for example, a standard Explorer or a more advanced Total Commander.
The idea is to copy the audio file to a special system directory. Unlike older versions of Android, the paths may be different in modern shells, but ringtones are usually reserved for specific folders at the root of internal memory. Creating a folder with the correct name often solves the problem of invisible files.
Copy your prepared MP3-Then create a new folder called Ringtones (for calls) or Notifications (for notifications). Note the letter register - the system can be sensitive to writing, so you'd better use capital letters, like in the example.
| Type of sound | Folder name. | Location. | Note |
|---|---|---|---|
| Incoming challenge | Ringtones | Root of memory | The main folder for calls |
| Notifications | Notifications | Root of memory | For SMS and messengers |
| Alarm clock | Alarms | Root of memory | Specific to the clock. |
| Systemic | uiSounds | Root of memory | For interface clicks |
Once you move files to the appropriate directories, go back to the audio settings menu, and now your track should be displayed at the top of the list or in the Local category, which works even if the file was downloaded from the browser to the random Downloads folder.
Using the “Themes” application for customization
The MIUI shell has a powerful built-in tool, the Themes app, which is not just a wallpaper catalog, but also a storage of sound profiles. Many Xiaomi Mi 9 users ignore this resource, although there are unique ringtones that are optimized specifically for the speakers of this model.
To take advantage of this method, open the Themes app on your desktop. In the bottom navigation bar, select the Sounds tab or search for Ringtone, where both free and paid options are available, often with high quality recordings.
Once you download your favorite sound, click the Apply button, and the system automatically sets the track to all types of calls, or suggests you choose a specific action, and the advantage of this method is that you don't have to search the files on the Internet and check their format — everything is already adapted.

The Secret of Regional Settings
Customization of individual melodies for contacts
One of the useful features of the Xiaomi Mi 9 is the ability to assign a unique ringtone to a specific subscriber, which allows you to know who is calling without looking at the screen, which is especially convenient when the phone is lying down or in the bag.
To implement this feature, open the standard Contacts or Phone app. Find the right subscriber in the list and go to the contact card. At the bottom of the screen or in the editing menu (pencil icon), find the Melody or Rington field.
Clicking on this field, you'll see a standard audio selection window, and the algorithm is similar to the general setting: you can select the system sound or find your file in memory, and after saving the changes when you call from this number, the selected composition will play, ignoring the general profile.
It is worth noting that if you set a common ringtone on No Sound, the individual settings for contacts can be overwritten, so make sure that there is any melody in the general profile, even quiet.
⚠️ Note: When you sync your contacts through your Google account, your individual ringtone settings may be reset to standard settings.
Solution: If the melody is not set
Sometimes Xiaomi Mi 9 users are faced with a situation where everything seems to be done correctly, but the phone continues to ring with a standard horn.The most common reason is access rights. MIUI shell strictly monitors application permissions, and the file manager may not be allowed to read audio data.
Check the permissions for the application you are trying to select a file through (like Explorer or Music). Go to Settings → Apps → All apps, find the right tool, and select Permissions. Make sure that access to Memory or Files is allowed.
Another reason could be a broken file or an incompatible codec inside an MP3 container. Try opening this file in any video player on your phone. If there is no sound or the player writes an error, the file needs to be replaced or recoded.
💡
The main reason for failure is that the file lies too deep in folders or has a name in Cyrillic, which the system cannot process correctly in the system partition.
Using third-party applications for sound management
If Xiaomi’s standard tools don’t seem functional enough, third-party apps from Google Play come to the rescue. Programs like Zedge or Ringtone Maker offer advanced editing and installing ringtones in one click.
These apps often have built-in editors that allow you to cut out the desired snippet of a song, add fade-in/fade-out effects, and immediately set the result on the call, which eliminates the need to search for computer programs to crop audio.
However, be careful with the permissions that such apps require: They request access to all audio files and contacts. Install only proven high-ranking programs so that your data is not compromised on the Mi 9.
