Changing the standard ringtone is one of the first steps that the owner of a new smartphone makes to personalize the device for himself. Xiaomi Mi 9, with a high-quality stereo speaker, is able to play complex musical compositions with excellent detail, so the use of factory beeps seems inappropriate. The process of replacing an audio file in the shell of MIUI has its own features that can confuse users who move from other operating systems.
In this article, we will take a look at all the methods available for installing ringtone, from classic gallery selection to advanced audio editing on-device, how to get around the limitations of the system when working with files from instant messengers and how to assign a unique melody for each contact in your phone book.
You need to understand that the Android file system that runs the Mi 9 requires you to properly place files in certain directories to display them correctly in the system menu. Ignoring the structure of folders often leads to the fact that downloaded music simply does not appear in the list available for installation.
Preparation of audio file and format check
Before you start setting up, make sure your audio file is compatible with the operating system. Xiaomi Mi 9 does a great job with popular compression formats, but for stable work it is better to use universal standards. Most users come across MP3 files that are supported by almost any software without the need for conversion.
If you plan to use high-quality records, you should pay attention to formats. FLAC or WAV, Although they take up much more space in the device's memory, Android may not display secure files in the ringtones list. DRM-Content or files downloaded from privately-access streaming services.
⚠️ Note: Files received through instant messengers (such as WhatsApp or Telegram) often have temporary names and may not appear in the standard tune selection menu until you rename them or move them to the system folder.
For comfortable work, it is recommended to download the necessary tracks in advance to the internal memory of the smartphone or to the memory card if the appropriate adapter is used. Storing music in cloud storage without prior download can lead to delays in an incoming call if the connection to the Internet is unstable at the time of the call.
Classic method of installation through system settings
The most reliable and standard way to change the ringtone on the Xiaomi Mi 9 is to use the built-in settings menu.This method ensures that the selected track will play correctly and will not disappear after the device is restarted. First, you need to open the main settings menu by finding the corresponding gear icon on the desktop or in the notification curtain.
Next, the action algorithm requires careful consideration, because menu items in different versions of MIUI may vary slightly, so you need to find the section responsible for sound and select the category that refers to voice calls, not to multimedia or alarm clock.
In the list that opens, you'll see a standard set of tunes preset by the manufacturer. To select your file, you'll need to scroll down the list or click on a special add-on icon, which usually looks like a plus or a symbol of a musical note, and the system will suggest you choose the source of the file: internal memory or file manager.
- 🎵 Open "Settings" and go to "Sound and vibration".
- 📞 Select "Call Melody" (make sure it's not "Alarm Melody").
- 📂 Press the badge"+" or "Select from Files" to open the Explorer.
- 🎧 Find the desired track in the list and confirm the choice with the “OK” button".
Once confirmed, the system will apply the changes instantly, and you will hear a test playback of the selected fragment, so if the sound is too quiet or, conversely, overloaded with bass, you can go back and choose another option or use the equalizer to adjust the frequencies.
☑️ Pre-installing check
Using the theme of design to change sounds
A unique feature of the MIUI shell is the deep integration of the theme store, which allows you to change not only the visual style, but also the audio of the interface. Unlike standard settings, the Themes store offers ready-made packages where ringtones are matched in the same style with icons and system sounds.
To use this method, you need to run the Themes app on your Xiaomi Mi 9. You can search for Ringtone or Sound to find specialized packages containing only audio files without changing graphics. This is convenient for those who want to quickly get a set of quality tunes for different events.
Once you download and apply the theme, the sounds will automatically be written to the appropriate sections of the system. However, be careful: using a full-fledged theme can change the appearance of the menu, which is not always desirable. In such cases, you can only use the sound profile if the theme functionality allows, or reset the visual changes by leaving the audio.
| Parameter | Standard settings | Tham's shop | Third-party annexes |
|---|---|---|---|
| Source of files | Local memory. | Online catalogue | Local Memory / Online |
| Difficulty | Low. | Medium | Medium/High |
| Reliability | Tall. | Tall. | Depends on the app. |
| Access to pruning | Aye (basic) | No. | Expanded |
Themes are especially important if you want to synchronize notifications, lock screens and incoming calls in a single style, which creates a sense of integrity of the interface, although it requires downloading additional data from the Internet.
Assigning an individual ringtone for contact
One of the most useful features of the smartphone is the ability to instantly know who is calling you, even before you look at the screen. Xiaomi Mi 9 allows you to assign a unique tune for each contact in the phone book, which is especially convenient in noisy environments or meetings.
To implement this feature, you need to open the Contacts or Phone app. Find the right subscriber in the list and go to the detailed information page. Depending on the version of MIUI, there may be a separate Melody button or it may be hidden in an additional menu designated by three dots or by the More button.
When you select the audio setting for contact, the system will ask you to select a track from the shared library or download a new one. Once installed, when you call in from that caller, the smartphone will play that particular file, ignoring the general volume and melody setting for everyone else.
⚠️ Note: If you reset your Contacts settings or sync them with a Google account that does not contain information about assigned ringtones, the individual settings may be lost and replaced with standard settings.
It's also a great way to track important calls without taking the phone out of your pocket, such as setting loud and Distinctive sound for calls from work or close relatives to keep a critical call from missing.
What if the contact doesn’t find the melody?
Working with audio files through file manager
Sometimes the standard player or settings menu does not see the downloaded file. In this case, the built-in Mi file manager comes to the rescue. Proper placement of the file in the system folder is a guaranteed way to make it visible to all applications on the system.
You have to open the Explorer app and go to internal memory, find a folder called MIUI, and inside it, a sound folder, and that's where the system expects user ringtones to arrive, and if the sound folder doesn't exist, you can create it manually, observing the letter register.
Copy or move your audio file to this directory. After that, it is recommended to restart the smartphone so that the Android media service scans the changes and updates the database of available sounds. Once the phone is turned on, the track will be available in the general list of tunes.
/storage/emulated/0/MIUI/sound/This method is especially useful for those who like to collect large collections of ringtones and sort them in advance, and it allows you to bypass interface bugs when the file selection button in the audio settings simply does not respond to clicks.
Advanced customization: cropping and editing tracks
The song isn’t always the right song to call the whole thing: the introduction can be too long and the climax begins too late. For the Xiaomi Mi 9, there are plenty of editorial apps that allow you to cut the desired snippet directly on your smartphone without using a computer.
Popular apps like Ringdroid or MP3 Cutter allow you to visually highlight the area (waves) of sound you want to use. You can set the exact start and end points, and add fade-in/fade-out effects to keep the call from breaking abruptly.
After editing, most of these applications offer to immediately install the cropped fragment as a ringtone, they automatically request the necessary permissions and prescribe the path to the file in the system settings, saving the user from manually copying files.
- ✂️ Download the audio editor from Google Play Market.
- 🎚️ Open the original track and select the desired segment.
- 💾 Save the file in format MP3 bitrate not less than 128 kbit/s.
- ✅ Click the "Install as a ringtone" button inside the app.
💡
Use the “Fade In” effect on the ringtone so that the sudden start of the music does not scare you and others in quiet rooms, such as the library or office.
Possible problems and ways to solve them
Despite the simplicity of the procedure, Xiaomi Mi 9 users may face a number of typical problems, most often related to application access rights or power saving features that aggressively restrict background processes.
If the phone is silent after installing the ringtone, check the sound profile, possibly activated "No sound" or "Do not disturb", which blocks the playback of user tunes, leaving only vibration, and it is also worth checking whether the loudness of the call is set too low in the side control panel.
In rare cases, a file may be corrupted by downloading or have incorrect ID3 tags that conflict with the MIUI media player. In this situation, it helps to transcode the file to a standard MP3 using a converter to a PC or re-download from another source.
⚠️ Note: When upgrading to a new version of Android or MIUI, All custom audio settings can be reset to factory values.
It’s also worth remembering compatibility: some older audio formats (such as WMA with protection) may not be readable by modern Android decoders without installing additional codecs that are not provided in the system.
💡
If the phone doesn’t see the file, rename it, leaving only Latin letters and numbers, and make sure the file extension is correct (.mp3).
