Changing the standard horn is the first step to personalizing a new smartphone. Poco X3 Pro owners often encounter features of the MIUI shell, where the installation process of an audio file is different from pure Android. Standard ringtones quickly get bored, and the user wants to hear exactly his favorite song when calling.
In this article, we will take a look at all the available ways to replace system sound, how to prepare the file correctly, where to move it, and what settings to change in the device menu, and the instructions are relevant for all firmware versions, including the latest security updates.
It doesn't require root rights or complex third-party software, but it requires a file manager and a basic understanding of the folder structure in the system, and we'll look at both the installation through audio settings and the direct method through the music play menu.
Preparation of the audio file for installation
Before you change your system settings, you need to make sure that the audio format itself is compatible with the operating system. Android works perfectly with MP3, M4A and WAV formats. If your music is recorded in a rare format, it is better to convert it in advance to avoid playback errors.
Sound quality also matters. High-bitrate FLAC or WAV files that are too heavy can take up space, although the current Snapdragon processors in the Poco X3 Pro can handle them easily. The best choice is MP3 with a bitrate of 192 kbps to 320 kbps.
It is important to pay attention to the length of the track, and system restrictions may prevent you from setting a track that is too long as a standard call.
⚠️ Note: Do not use files with DRM-The system cannot reproduce them as a system ringtone without a special decoder.
For easy file management, it is recommended to use the built-in Explorer or install a more functional analogue, such as Total Commander or FX File Explorer, which will simplify navigation through hidden system folders.
Classic method through sound settings
The most reliable way to change a tune is to use the built-in settings menu, which ensures that the file is correctly registered in the system and does not disappear after the reboot.
To start, open the settings menu on your smartphone. Find the section "Sound and vibration." In some versions of the firmware, it may simply be called "Sounds." Here are all the volume sliders and the selection of themes.
From the menu that opens, select Melody or Rington, and you will see a list of standard songs from Xiaomi and Google, but we are interested in the add button.
- 🎵 Click on the plus icon or the Add Melody button at the top of the screen.
- 📂 The system will open the built-in audio player, where you need to select "Music on the device».
- 🎶 Find the right track in the list and click on it to install it.
Once selected, the composition will automatically become the main call for all SIM cards. If you use two SIM cards, repeat the procedure for the second one by selecting the corresponding item on the menu.
☑️ Pre-installing check
Installation of the melody through a standard player
There is a faster way that is often overlooked: Xiaomi’s standard Music app lets you assign tracks to a call directly from the playlist, saving time and not requiring a deep dive into the settings menu.
Open the Music app. Find the tracks you pre-loaded into your phone's memory. If you're using a third-party player like Mi Music or PowerAmp, the algorithm will be similar.
Click on three dots next to the title of the track or press your finger on the track to call the context menu. In the action list, select the "Call to Call" option. The system will immediately apply the changes without further confirmation.
This method is especially convenient when you listen to music and suddenly decide to put your favorite fragment on an incoming call.
Why isn't there a song on the list?
Set up individual ringtones for contacts
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. In the Poco X3 Pro, this is done through the Contacts or Phone app.
Open your contact list and select the person you want to be. Click on the profile edit (usually a pencil icon or three dots). In the edit menu, find the Melody or Rington field.
The default is "Default"; click on it and the standard audio selection window opens, and you can select both the system sound and any file from the device's memory using the Add button.
| Type of contact | Priority of sound | Where to set up |
|---|---|---|
| Elected | High-pitched | Contacts → Chosen |
| Frequent | Medium. | Telephone → Magazine |
| Others | Common | Settings → Sound |
Make sure that you have loud and noticeable tunes for important contacts, which will help you not miss a critical call in a noisy environment.
💡
Tip: For critical contacts, not only set a unique tune, but also turn on the “Repeat the signal” function so that the phone rings until you pick up the phone.
Solution: the file is not visible in the system
A common problem of Xiaomi users – the phone “can’t see” downloaded mp3-The files in the ringtone selection menu, which is related to the features of scanning media files in the shell. MIUI. The system does not always automatically index new folders.
To fix this, you need to put the audio file in a special system directory. Use the file manager and go to the root of the internal memory. Find the Ringtones folder. If it's not there, create a new folder with that name (case-sensitive).
Copy your music files into this folder. Then restart your smartphone. When you start, the system scans the Ringtones directory and adds its contents to the list of available tunes.
An alternative way is to use MIUI → sound → ringtone, but using the Ringtones root folder is considered a more versatile method that works on all versions of Android.
⚠️ Note: Do not delete system files from folders MIUI Copy only your files into directories you created or into the Ringtones folder so that the interface doesn’t break down.
If the sound doesn't appear after the reboot, check the Explorer or Music app's access permissions. Allow access to all media files in the privacy settings.
💡
Putting a file in the Ringtones folder and then restarting it is a guaranteed way to make the system see a new ringtone.
Setting up notifications and alarm clock
Personalization isn't just about incoming calls, but it's about app notification sounds and alarms, and it creates a unified acoustic environment for your device.
To change the notification sound, go to Settings → Sound and Vibration → Notifications. Here the principle is the same: choose a standard sound or add your file. Note that for different applications (SMS, Viber, Telegram), the settings may be inside the applications themselves.
To change the alarm clock, open the Clock app. Choose the right alarm clock or create a new one. In repetition or sound settings, select Add Melody and specify the file from memory.
It is recommended to choose the alarm clock incremental melodies to wake up softer, sharp sounds can cause stress in the morning.
- ⏰ Open the "Clock" app».
- 🔔 Click on the bell icon or "Sound».
