Changing the standard melody to a personalized track is the first step to making the Xiaomi Redmi 9 a true device. Standard ringtones preinstalled by the manufacturer often sound the same for many users, which can lead to confusion in public places or offices. Installing a unique composition allows you to instantly incoming call even without looking at the smartphone screen.
The MIUI sound personalization process has its own characteristics that set it apart from pure Android. Users may experience system file access restrictions or no file selection button in the standard settings menu. However, there are several proven ways to get around these limitations and install any audio file as a call signal.
In this article, we will discuss all the current methods of installing music on a call, from simple actions through settings to working with the file system through the computer. You will learn how to configure individual tunes for different contacts and what to do if the system does not see downloaded tracks. The key is the correct location of the file in the device memory, since MIUI strictly controls access to system sounds.
Audio file preparation and format requirements
Before you start setting up, you need to make sure that your audio file meets the technical requirements of the operating system. Android, which runs MIUI 12 or a newer version on Redmi 9, supports most popular formats, but for stable operation it is better to use standard codecs. The optimal choice will be an MP3 file with a bit rate of at least 128 kbit / s.
It is also important to pay attention to the length of the track. Too long songs can be cropped by the system or incorrectly displayed in the contact list. It is recommended to use fragments of 15 to 40 seconds, containing the most recognizable part of the song. If the file is too long, it is better to crop it in advance using built-in tools or third-party applications.
The file should be stored in the phone’s internal memory or on an SD card if installed. The system will not be able to install the ringtone if the file is in the secure folder of the application or in the messenger cache. For convenience, it is recommended to create a separate directory called Ringtones at the root of the internal memory, where you will put all the desired tunes.
⚠️ Note: Files downloaded through a browser or received through messengers (WhatsApp, Telegram, Viber) are often stored in hidden or nested folders with a complex path structure. To simplify the search, move the desired track to the root folder or to a specially created directory Music.
Standard method of installation through sound settings
The easiest and most obvious way to change a tune is to use the smartphone's built-in settings menu.This method is suitable for global changes when you want the same track to sound on all incoming calls. Xiaomi Redmi 9's interface is intuitive, but hidden options may require attention.
To start, open the Settings app and find the audio section. Depending on the firmware version, it can be called Sound and Vibration or just Sounds. Here you'll see a list of standard tunes, broken down by category. At the bottom of the list, often there's an Add Melody button or a plus icon that the file manager opens.
If you don't see the add button, try clicking on the current melody name. The pick box that opens may give you the option to go to the device files. Select the track from the list and the system will automatically apply it. If there is no file select button, it means that your version of the shell requires the use of a theme or a special access method, which will be discussed below.
After selecting a track, be sure to check the volume of the call. Personalized files can play quieter system tunes due to differences in coding. Make sure the call volume slider is set to a comfortable level so you don't miss an important call.
Using the “Themes” application to access files
In some versions of MIUI firmware, direct ringtone installation through sound settings is blocked or hidden by developers, in which case the regular Theme app, which is part of the Xiaomi ecosystem, comes to the rescue.
Open the Themes app on your Redmi 9. In the lower right corner of the screen, find the user profile icon (usually a person image). Click on it to open the profile menu. In the options list, select Ringtona, which opens a full file manager that allows you to select any audio file available in the device memory.
Click the Select Melody from Memory (or similar) button, and a conductor will open where you can go to the folder with your music. Once you select a track, it will appear in the list of available ringtones. To apply it, click Apply and select Call Melody from the menu that appears. Now your song is set as the main signal.
☑️ Pre-installing check
This method also allows you to remove custom tunes, and if you get bored of the track, you can go back to the ringtones menu through the Themes app, find the track in the list, and press the delete button, which is convenient for memory management and keeping order in the sound list.
Installation of a melody through a computer and file manager
If you prefer to work with files on a large screen or you do not have the ability to download the track directly to your phone, you can use a computer. Connect Xiaomi Redmi 9 to a PC via a PC USB-In the notification on the phone screen, select the file transfer mode MTP.
On your computer, open the device that appears in My Computer. Find the phone's internal memory. To guarantee the track's display in the system, create a folder called Ringtones at the root of the internal memory. If such a folder already exists, just copy your audio file there. You can also use the MIUI -> folder, but it may require additional rights.
The path to copy: /Internal memory/Ringtones/Once you copy the file, disconnect the phone from your computer. Go to the sound settings on your smartphone. Your file should appear in the list of available tunes, often at the bottom of the list or in a separate category of "User." If the file does not appear immediately, try restarting the device so that the media service scans the memory.
| Method | Difficulty | I need a PC. | Reliability |
|---|---|---|---|
| Sound settings | Low. | No. | Medium |
| Annex Topics | Low. | No. | Tall. |
| Through PC (Ringtones folder) | Medium | Yes. | Tall. |
| Third-party annexes | Tall. | No. | Medium |
Why can't the file be fixed?
Set up an individual call for contact
One of the most useful features of a smartphone is the ability to assign a unique tune to a specific person, which allows you to know who is calling without taking the phone out of your pocket. On Redmi 9, you can do this directly from the phone book.
Open the Phone or Contacts app. Find the right subscriber in the list and open their card. Click on the More button (three dots or an edit icon) and select Set a ringtone. If there is no such item on the menu, try tapping the pencil icon to edit the contact.
In the list that opens, select Select from files or find the name of your previously installed composition. Once the choice is confirmed, a note icon will appear next to the contact name indicating personalization. Now, when that person calls, you will hear his track.
⚠️ Note: If you change your phone number or subscriber contact details, the personal setting may be lost, as well as if the contact is saved in a Google account or if you have a Google account. SIM-The system may not allow you to change the sound settings for the card with restrictions, in which case copy the contact to the phone memory.
For mass customization or deeper contact management, sync with Google Contacts via the web interface can be used, however, local customization on the Xiaomi device itself is often more stable and faster to apply.
Solution: When a melody is not put
Users often face a situation where all actions are done correctly, but the music is not playing or the system is giving an error. One common reason is the file format. Make sure the file is not protected by DRM digital rights, which is often the case with tracks from paid subscription streaming services.
Another problem is the path to the file. The MIUI shell, for security reasons, can restrict applications from accessing certain folders. If you can't select a file, try moving it to the Download or Music folder. Avoid deep nested folder structures.
It’s also worth checking the permissions for the Themes or Explorer app. Go to Settings → Apps → All apps, find the right app and make sure it has access to Memory or Files. Without that permission, the program simply won’t “see” your audio file.
💡
Use a third-party file manager, such as Total Commander or MiXplorer, if standard Explorer does not allow you to copy a file to the desired system folder.
If nothing helps, try converting the file to a different format or changing its bitrate, sometimes by simply renaming the file, removing special characters or emoji from the name that may not be properly handled by the system.
Use of third-party applications for ringtones
If standard methods seem too complex or limited, there are many specialized applications available on the Google Play store, programs like Zedge, Ringdroid or MP3 Cutter allow you to not only select but also edit tracks on the fly.
These applications often have built-in sound and effect databases, which can automatically scan the device's memory and offer user-friendly interfaces to crop the beginning and end of a track, which is especially useful for creating short but spectacular call signals from long pieces of music.
However, be careful when installing such programs. Many of them contain advertising or require excessive permissions. Before installing, carefully read reviews and check access rights. For the basic task of installing a call on Xiaomi Redmi 9, the built-in system features described above are often enough.
💡
The fastest and most reliable way to install a call on Xiaomi Redmi 9 is to use the built-in Themes app through the user profile, as it has system rights to change the audio settings.
