Melody set for contact in Xiaomi Poco X3 Pro

Call personalization is not just a matter of aesthetics, but also an important element of ergonomics of using a smartphone. When the device is in your pocket or lying down, it is a unique melody that allows you to instantly understand who is trying to contact you without taking out the gadget. For owners of the powerful Xiaomi Poco X3 Pro, this feature is implemented in the shell of MIUI quite flexibly, but has a number of features that distinguish it from pure Android.

Owners often find that standard audio settings do not allow you to immediately assign a track to a specific person from the phone book, this is due to the peculiarities of the system applications Contacts, Phone and Music, which in Xiaomi firmware can be divided into different menus. To avoid confusion and ensure that you install the right track, you need to clearly follow the algorithm of actions described below, given the version of the installed operating system.

There are several proven ways to do this, from the classic method through the contact menu to more advanced options using third-party file managers. The key is to correctly locate the audio file in the device's memory and correctly allow applications to access, and if you ignore these nuances, the system can simply ignore your choices or reset your settings after rebooting.

Preparation of audio files and format verification

Before you start setting up, you need to make sure that your audio file meets the technical requirements of the system. Xiaomi Poco X3 Pro supports most popular formats, but for stable operation it is better to use standard codecs. Most often there are no problems with MP3, M4A or WAV formats. If your ringtone is recorded in a rare format, such as high-bitrate FLAC, the system may not display it in the list of available ringtones.

It is also important to pay attention to the length of the track. Too long songs can be cropped by the system or play incorrectly when an incoming call. The optimal duration is from 15 to 40 seconds. If the file is too long, it is recommended to pre-edit, leaving only the most recognizable fragment, you can use the built-in editor in the Music application or third-party utilities.

Files must be saved in the available memory of the device. The system folder for ringtones on Xiaomi is usually on the path /MIUI/sound/ or /Android/media/audio/ringtones/, however, for user tunes it is more convenient to use the root folder or specially created directory "Ringtones" at the root of the internal drive, which will make it easier to find the file at the time of setting.

💡

Use audio files with a bit rate not higher than 320 kbit / s. Files with excessively high quality (Hi-Res) can cause a delay when you start playing a call due to the time for decoding by the processor.

Once you download or create a file, check it through a standard player. If the sound is clean and the file opens without errors, you can proceed to the next step. Make sure the file is not protected by digital rights (DRM), as such tracks from streaming services can not be used as system notifications without removing protection.

Basic method of installation through the Contacts application

The most direct and logical way to assign a tune is to use the built-in Contacts app, which works most of the time and doesn’t require additional software, but the interface may vary slightly depending on the version of MIUI you have installed on your Poco X3 Pro.

To start, open the Contacts app and find the right subscriber in the list or through a search. Click on the contact name to open their card. From the menu that opens, select Change or click on the pencil icon, usually located at the bottom of the screen or in the top corner. You will need to go to the expanded settings menu for that particular number.

• 🎵 Click on three dots in the top right corner of the contact edit screen.
• 🔊 In the drop-down menu, select "Call Melody" or "Rington".
• 📂 A system player will open, where you can select a track from preinstalled or click "Select a melody on the device".
• ✅ After selecting the file, click “OK” or tick to save the changes.

Sometimes users are faced with a situation where the selection of the melody is absent. This may be due to the fact that the contact is synchronized with a Google or Mi Account account, and some fields are edited only through the web interface. In this case, try the method described below, through global audio settings, which often bypasses the limitations of the contact editor.

Alternative way through sound settings

If the direct method didn't work, you can use the system's sound settings, which is more versatile, and allows you to control the sound circuitry for different types of contacts, including hidden numbers or unknown subscribers, even though our target is a specific person.

Go to the main settings menu of your smartphone, find the section "Sound and vibration." Here you are interested in "Call melody." By clicking on it, you will be taken to the track selection menu. At the bottom of the list, there is often a button "Add ringtone" or a similar option to select a file from memory.

However, to assign this track to the contact, rather than to all incoming ones, after selecting a file in this menu, sometimes additional manipulation is required. In some versions of MIUI, after selecting a file, the system asks: "Apply for all contacts or for a particular?". If there is no such question, return to the contacts, select a subscriber and the melody field now should display the track you have chosen.

⚠️ Note: When you upgrade or reset your personal call settings may be reset to standard, it is recommended to back up your contacts with a link to the cloud service, although the audio files themselves will need to be stored separately.

Also, through the audio settings, you can check whether the "No Sound" or "Do Not Disturb" mode is on for the selected contacts, and make sure that there are no restrictions for the important subscriber that block the audible alert, even if the melody is assigned correctly.

Using a file manager to assign a track

The standard MIUI file manager is a powerful tool that is often ignored when setting up media, allowing you to find audio files where the system player does not see them and force them to assign them to contacts.

Open the Explorer app and go to Music or find the folder where you saved the ringtone. Click on the file and hold your finger until the context menu appears. In the action list, select Use as or Set as and then Call Melody.

The system will redirect you to the contact selection menu, and you can mark one or more numbers that will be affected by this sound, which is especially useful if you downloaded a track from the Internet and it is in the Download folder, where the system settings sometimes "fall short" in a standard search.

If the system issues an error or simply closes the menu after selecting a file, the problem may be in access rights. Go to Settings → Applications → All Apps → Contacts and make sure that access to the device’s memory is allowed. Without this permission, the application will not be able to “read” the audio file you selected.

Configure contacts with several SIM-map

Xiaomi Poco X3 Pro supports the work of two SIM-So you can assign different tunes to the same contact depending on which SIM card is being called, although this is difficult to do with standard means.

Usually, the system ties the melody to the contact globally, regardless of the SIM card. However, if you want to differentiate calls, you can use a trick: create a duplicate of the name-name contact (for example, "Ivan Work") and assign him a separate melody. Save the work number on the second SIM card under that name.

In the audio settings (Settings → Sound and Vibration → Additional), you can adjust the individual volumes and vibration types for the SIM 1 and SIM 2. This helps distinguish calls even without unique melodies using tactile recoil.

The ringtone of the call is always determined by the contact in the phone book, not the SIM card that was called. Xiaomi’s approach is unique in the deep integration of Mi services, which can sync these settings with the cloud.

Problem Solving: Why the Melody Doesn't Work

Often, users are faced with a situation where everything is done according to the instructions, but a standard horn rings. One of the common reasons is aggressive battery optimization. The MIUI system can kill the processes responsible for playing user ringtones to save charge.

To fix this, look in the Music or Sound and Vibration app settings (depending on what the track is playing) and select Unlimited mode. Also check if the silent mode is enabled for specific contacts inside the subscriber card.

⚠️ Note: If you use a third-party theme, it may overlap the system settings of the sound. Try temporarily switching to the standard theme "Classic" in the Themes app to see if the conflict will go away.

Another reason is the file format. Even if the.mp3 extension, there may be a custom codec inside. Convert the file to AAC or a standard MP3 with a bitrate of 128-320 kbps. Also check the path to the file: some system partitions are closed to read by root-free call applications.
