Personalizing a mobile device isn’t just a matter of aesthetics, it’s also a way to instantly know who’s calling you without getting your phone out of your pocket. Budget and mid-budget smartphone owners often face the limitations of standard interfaces, but the MIUI operating system installed on Xiaomi Redmi 9 provides flexible tools to manage audio notifications. The process of replacing a standard horn with a favorite song can seem confusing due to the nature of the shell, but with the right approach it takes only a couple of minutes.
There are several proven ways to accomplish this, ranging from using a built-in music player to manually copying files through a file manager. It is important to understand that the Android system on which MIUI is based requires a certain folder structure to correctly display tracks in the list of available ringtones. In this article, we will discuss each method in detail, paying attention to the nuances of working with the file system and application access rights.
Audio file preparation and format verification
Before you start setting up, you need to make sure that the audio file you choose is compatible with the smartphone operating system. Xiaomi Redmi 9 easily reproduces the most common formats such as MP3, WAV and OGG. However, to ensure maximum stability and the absence of artifacts when playing, it is best to use a classic MP3 with a bit rate of at least 128 kbit / s.
If you plan to use a snippet of a song rather than the entire song, it is recommended to pre-cut the track to the desired length. The optimal ringtone duration is 15 to 30 seconds: too short a sound may not be heard in a noisy environment, and a long one interrupted by an incoming call before you have time to answer.
It is also important to pay attention to the quality of the original file: Downloading a low-bitrate melody (less than 96 kbps) can lead to wheezing and distortion of the sound through a speaker that, despite having sound enhancement technology, has its own physical limitations.
💡
For incoming calls, melodies with a pronounced, ringing initial part (attack of sound) are best suited, since it is the first seconds that are most important to attract the attention of the owner.
Method of installation through built-in music player
The easiest and most intuitive way to install your tune on Xiaomi Redmi 9 is to use the standard Music app, which is preinstalled in the MIUI system. This method does not require a computer connection or the use of third-party file managers, which makes it ideal for users who appreciate simplicity.
To start, open the Music app and find the track list that you want to use. Click on the track name to open the play screen, and then tap the menu icon, which is usually represented by three dots or vertical bars in the upper right or lower corner of the screen. In the context menu that opens, you need to find the item "Use as" or "Configure", then the system will suggest select the notification type.
Next, select the Call option (or Call Melody). The system automatically creates a copy of the file in the ringtone system folder and applies changes. If you want to install the track only for a specific contact, select the appropriate item, and the phone will prompt you to select the person from the phone book. Once confirmed, the selected composition will become standard for all incoming calls.
☑️ Algorithm of installation through the player
Manual installation through file manager
If the standard player for some reason does not display the desired function or you prefer full control of the file system, you can use the manual method. It requires moving the audio file to a special system directory, where Android searches for custom ringtones, you need a built-in Explorer application or any other file manager with internal memory permissions.
First, find the downloaded audiophile in the device's memory. Usually, these files are in the Download or Music folder. Select the file, click on it and select Copy or Cut. Then you go to the root directory of internal memory and find a folder called Ringtones. If you don't have one, you can create it manually, but on Xiaomi Redmi 9, it's usually present by default.
Once you paste the file into the Ringtones folder, restart your smartphone or just wait a few seconds for the system to index the new media. Then go to the sound settings: Settings → Sound and Vibration → Phone Call. Your song should appear in the list of available tunes in the All or User section. Select it and click OK.
⚠️ Note: When manually copying, make sure you don’t delete the original file from the download folder, if you didn’t move it, but copy it. Also make sure the file name doesn’t contain special characters that may not display correctly in the system.
Set up an individual call for contact
One of the most useful features of the smartphone is the ability to assign unique tunes to different subscribers, which allows you to instantly determine who is calling — a loved one, a colleague or an unknown number — without looking at the screen. On Xiaomi Redmi 9, this feature is implemented through the standard “Contact” or “Phone” application.
Open the Contacts app and find the person in the list. Click on their name to open their contact card. At the top of the screen or in the menu (three dots in the corner), find "Sound" or "Melody." The system will suggest selecting a track from the list of available files that should have been added by previous methods. Select the desired composition and save the changes.
It's worth noting that if you change a contact's phone number or combine two cards, the audio settings may reset, and you'll have to repeat the procedure, and the individual melody won't work if the contact doesn't have a phone number or is hidden by privacy settings. SIM-map.
| Type of setup | Where it changes | Priority | Features |
|---|---|---|---|
| Common ringtone | Settings → Sound | Low. | It is for anyone who does not have an individual setting. |
| Contact | Contact card | High-pitched | Overrides a common call for a specific person |
| Contact group | Annex Contacts | Medium. | Convenient for colleagues or family, requires group formation |
| Do Not Disturb mode | Settings → Sound | critical | Blocks all sounds except for selected contacts |
What if the contact melody doesn’t play?
Installation of melody on SMS and notifications
Sound is important not only for voice calls, but also for messages. On Xiaomi Redmi 9, you can customize individual sounds for SMS, messaging (if they support system notifications) and system events, which helps differentiate important emails from advertising mailings.
The process is similar to setting a ringtone, but the path in the menu is slightly different. Go to Settings → Sound and Vibration → Additional. Here you will find the Notification Sound and SMS Sound. Clicking on these will take you to the same audio list where you can select a previously downloaded file. For messages from apps (WhatsApp, Telegram), the settings are usually located inside the apps themselves in the Notifications section.
Users often forget that the volume of notifications is adjusted separately from the volume of the call. If you set a beautiful melody but you can't hear it, check the notification volume slider in the Quick Settings menu or in the Sound and Vibration section. Make sure that the Notifications type is not "No Sound" for the sound type.
💡
Call volume and media/notification volume on MIUI are independently controlled, so check both sliders for sound problems.
Solution: The melody is not put or heard
Despite the simplicity of the procedure, users of Xiaomi Redmi 9 can face a number of typical problems, most often they are related to application access rights or features of the MIUI optimizer. If you can not choose the file as a ringtone, perhaps the music player or conductor does not have permission to access memory.
Check permission settings: go to Settings → Apps → All apps, find the player or explorer you are using, select Permissions and make sure that access to Memory or Files is allowed. Without that, the system menu simply won’t see your audio files.
Another common problem is that the file is too long or has an unsupported codec inside the container. Some M4A or FLAC formats may not be read by the system caller, although they are played by the player, in which case converting the file to a standard MP3 using online converters will help.
⚠️ Warning: If after setting the melody, the phone is making a short squeak instead of music, it is a sign that the file is damaged or its bitrate is too high for a system call.
Use of themes and third-party applications
For those looking to expand their functionality, MIUI Themes offers packages that include not only wallpaper and icons, but also sets of sounds. However, installing third-party ringtones through the theme store can be paid or require downloading unnecessary components.
These applications often have built-in databases of popular tunes and allow you to edit tracks directly on your phone. When using third-party software, it is important to read permission requests carefully: the application to install the ringtone will need access to Phone and Memory. Without these rights, it will not be able to change the system settings of the sound.
Remember that installing a large number of third-party themes and ringtones can slightly increase the consumption of RAM, but on the Xiaomi Redmi 9 with its RAM capacity, this usually does not cause performance problems.
