Changing the standard ringtone is the first step to personalizing your Poco X3. Standard sounds that are preset by the manufacturer can quickly get bored or merge with other people's notifications in a public place. Replacing them with a favorite song or a unique audio file allows you not only to stand out, but also instantly recognize the incoming call, without even taking your smartphone out of your pocket.
The MIUI operating system that runs the device offers flexible options for managing audio profiles. However, the settings interface sometimes changes depending on the firmware version, which can confuse the inexperienced user. In this article, we will discuss all the current ways to replace a call, from the classic method through settings to advanced options for working with the file system.
The installation process doesn't require root rights or a computer connection. All the tools are already built into the Xiaomi shell. You just need the audio file you want to use. It can be a track downloaded from the Internet, or a recording you created yourself. Let's take a closer look at each step so you can customize the sound exactly as you want.
Preparation of an audio file for installation
Before you start settings, you need to make sure that your music file is in the right format.Poco smartphones easily reproduce most popular formats, but MP3 or M4R are best for system ringtones. If you downloaded a file in WAV or FLAC format, the system can automatically convert it when you choose, but it is better to have a finished track.
The location of the file in the memory of the device plays a critical role. The standard file manager MIUI sometimes "does not see" the music if it lies in the back of the folders. The optimal solution is to move the track to the root directory or a specially created folder Music/Ringtones, which will simplify the search and guarantee that the system will index the new sound.
💡
Download ringtones only from trusted sources to avoid getting malicious code or advertising viruses along with the audio file.
Track length also matters. Too long songs can be cropped by the system or incorrectly displayed in the selection list. It is recommended to use fragments from 15 to 30 seconds in length. You can use a built-in voice recorder or third-party editor apps that are easy to find on the Google Play store to trim.
- 🎵 Make sure the file has an extension.mp3 or.m4r for maximum compatibility.
- 📂 Move the track to the Downloads or Music folder for quick access.
- ⏱️ The optimal duration of the ringtone is 20-30 seconds.
Installation of the melody through the standard settings menu
The easiest and most reliable way to change the sound is to use the built-in functionality of the system. To do this, unlock the screen of your Poco X3 NFC or Pro version and find the Settings icon. The interface may differ depending on the theme of the design, but the logic remains the same for all devices in the line.
In the menu that opens, you have to find the audio section, usually called Sound and Vibration, where you have all the volume sliders and the lists of available tunes, and you have a few preset options, from classic trills to modern digital signals.
☑️ Pre-installing check
To put your track, click on "Rington" and you'll see a list of all available sounds. At the top of the screen, there's often a "+" button or a plus icon that allows you to add a file from the device's memory. After you click, the system will prompt you to select an audio file through the built-in Explorer.
⚠️ Note: If you don’t see the file add button, try changing the view of the list display or checking if the system partition is hidden in the Explorer settings.
Once you select a file, it automatically becomes the main melody of the call. You can immediately test the result by asking someone to call you or making a test call from another number. If the sound is played quietly or wheezing, check the equalization settings or the quality of the source file itself.
Set up a call through the “Themes” app
In the Xiaomi ecosystem, the Themes app is not only used to change icons and wallpapers, but also a powerful sound management tool, and you can find thousands of free and paid ringtones that are optimized specifically for Poco devices, eliminating the need to search and download music in the browser.
To access the sound library, open the Themes app and go to the Melodies profile or section, and you have a handy catalog of categories: pop music, classics, nature sounds, effects from games and movies, and you can listen to any track before downloading, which is very convenient for quality assessment.

Using a File Manager for Advanced Users

Open the File Manager app and go to Audio or Music, find the file you want, click on it, and hold your finger until the context menu appears. In the action list, select Set to Call or Use as a Rington, and the system will immediately apply the changes.
The Way to the Folder: Internal Memory → Music → RingtonesIf you don't have a direct installation, you can just move the file to the Ringtones system folder. Once you reboot your smartphone or update the list in the audio settings, this track will appear in the general list along with the factory tunes. This is especially true for files downloaded from instant messengers, which are often hidden in the back of folders. Android/media.
⚠️ Note: Do not delete system files from audio folders unless you are sure of their origin.
Specific settings for different SIM-map
Owners of two-simulated versions of Poco X3 Often face the need to distinguish calls from different numbers. MIUI It allows you to assign a unique melody to each of them. SIM-This helps you understand which number you're calling without looking at the screen.
In the Sound and Vibration menu, look for the Rington section, and you'll see two subsections, "SIM 1" and "SIM 2," and you can click on each of them to select a customized composition, for example, you can set a strict short signal for work, and for personal contacts, your favorite song.
| Parameter | SIM 1 | SIM 2 | Common |
|---|---|---|---|
| Choosing a tune | Individually | Individually | By default. |
| Vibration. | Tune in. | Tune in. | Standard |
| Loudness | General | General | Regulated |
| Silence mode. | Yes. | Yes. | Yes. |
This flexibility makes it as comfortable as possible to use two numbers, so you don't confuse an important work call with a second SIM promotional mailing, just make sure that the settings define which SIM is the default for calls, unless you manually select each time.
What to do if the melody is dropped?
Designation of unique sounds for contacts
A special level of personalization is when you know who is calling from the first seconds of a tune. Xiaomi Poco X3 allows you to assign individual ringtones for specific contacts from the phone book. This is a very useful feature that allows you to avoid missing an important call from a loved one or boss.
To do this, open the Contacts or Phone app, find the person you want, and go to the subscriber card. Click on the "More" (three dots) or "Change" button. From the menu that opens, select "Melody" or "Rington" and then select the track from the list or add yours, as described earlier.
Now, when that person calls you, the phone will play that particular sound, ignoring the general settings, and if the caller calls from another number that isn't in contact with that name, the standard tune will play, so it's important that the number is properly stored in the phone's memory or synced to your Google account.
- 👤 Open the contact card in the phone book.
- 🔔 Select the item "Melody" in the editing menu.
- ✅ Save the changes to apply the new sound.
Solving Sound Problems
Sometimes users are faced with a situation where the set melody is not playing, only part of the track is playing or the sound is too quiet. Often the reason lies in the file format. Despite the stated support, some bitrates above 320 kbit / s can be incorrectly processed by the system player of calls.
Another common problem is the Do Not Disturb or Quiet Mode mode enabled, in which case the phone will only vibrate while ignoring the audio file. Check the side volume swing and make sure the call slider is raised up. It's also worth checking the sound profile settings in the quick menu.
💡
The quality of the ringtone directly depends on the original file: the cleaner the recording, the better it will sound through the smartphone speaker.
If the sound is late, it may be too heavy or has a complex coding structure. Try converting the track to a simpler format or shortening its duration. In rare cases, cleaning the cache of the Themes or Sound application through the application management menu helps.
