Changing the standard ringtone is one of the first steps that makes the new smartphone truly yours. Xiaomi Poco X3 has quality speakers capable of playing complex compositions without distortion, but the regular MIUI sounds can seem boring or too quiet. Users often look for ways to replace them with favorite tracks from their personal collection or download fresh sounds from the Internet.
The process of installing an audio file on the Poco X3 NFC or the Pro version does not require root rights and is performed using the regular tools of the Android operating system. However, the MIUI shell has its own features of navigating the file system that can confuse the beginner. In this guide, we will discuss in detail all ways to personalize audio.
You can set music not only to incoming calls, but also customize unique sounds for notifications, alarms and even individual contacts, which will instantly understand who is calling you without taking your phone out of your pocket.
Preparation of an audio file for installation
Before you start setting up the system, you need to make sure that the audio file itself is in the correct format and readable by the phone. MIUI works best with MP3, WAV and OGG formats. If you downloaded the file from an unverified source, it can be in M4A or FLAC format, which are also supported, but sometimes require conversion to display correctly in the ringtones list.
The file can be downloaded directly through the browser on your smartphone or transferred from your computer through USB-In the second case, you need to select the mode of operation after the connection. USB in the notification curtain. select File Transfer or MTP, so that the computer sees the internal memory of the device as an external drive.
Where's the best place to keep ringtones?
It's important to remember the length of the track. Too long songs can break off or work incorrectly as a call signal. The optimal duration is 15 to 30 seconds. You can use the built-in editor in the Music app or third-party snails to trim.
Installation of the melody through the standard settings menu
The most reliable and correct way to change the sound of a call is to use the system menu, which ensures that the file is registered in the sound registry and does not disappear after rebooting. Open the Settings app on the home screen or in the curtain.
Next, go along the way, find the Sound and Vibration section, and you'll find a lot of volume sliders in the menu that opens, but we need a Phone Call (or Rington) item, and by clicking on it, the system will suggest you select a track from the standard library or from the device's memory.
- 🎵 Press the button. + or a plus icon at the top of the screen to open the file manager.
- 📂 Find a folder where you previously saved or copied your audio file.
- ✅ Slip the title of the composition to listen to it and confirm the choice.
Once you select a track, it automatically applies to all incoming calls. SIM-Note that in Poco, note that X3 You can assign different tunes to each SIM, and you can choose the settings separately for the same Sound and Vibration menu. SIM 1 and SIM 2.
☑️ Pre-installing check
Using the "Themes" application to search for sounds
MIUI is famous for its theme store, which is a powerful customization tool. Themes app not only features wallpaper and fonts, but thousands of free ringtones created by the community, which is a great option if you don't want to mess around with downloading files from your browser.
Run the app, and in the bottom navigation bar, select the Ringtones tab, and here's a huge library, sorted by category: classic, sound effects, and others, and you can listen to any track right in the app before you install it.
To set the sound you find, press the download button (down arrow) and then the Apply button after you finish downloading it. The system automatically redirects you to the audio settings menu where you want to confirm the action, and the advantage of this method is that all files are already optimized for your Poco X3 speakers.
⚠️ Note: When using the Topics store, pay attention to the author's rating and downloads. Some custom ringtones may be too quiet or have poor coding quality.
Customization of individual sounds for contacts
One of the most useful features is to set a unique call for a specific person, so you can see who is calling without even looking at the screen, and you'll need a standard Contacts app or Phone to do this.
Open your contact list and find the person you want to call. 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 the Sound or Call Melody item, and the default is Default.
Clicking on this item will take you to the already familiar track selection menu, select any track from the list or add a new one through the file manager, and once confirmed, this contact will ring with a unique sound, ignoring the general system settings.
| Type of setup | Where it changes | Priority |
|---|---|---|
| Common ringtone | Settings → Sound | Low (baseline) |
| Contact (VIP) | Contact card | Tall (interrupts) |
| Contact group | Annex Contacts | Medium. |
| Don't disturb mode. | Settings → Sound | Locks everything down. |
💡
If you have a contact group (e.g., “Work” or “Family”), you can assign a separate ringtone to the entire group directly through the group management menu in the Contacts app.
Replacement of notifications and alarm clock
Personalization isn't just about calling, but the notifications from messengers and alarms can also be replaced with more pleasant ones, and there are separate items on the Sound and Vibration menu for Notifications and Alarms.
The procedure is similar to setting a ringtone: select a point, press the current sound and change it to a file from memory. However, for an alarm clock, it is better to choose tracks with a sharp start to ensure you wake up, as opposed to smooth melodies for calls.
For social media notifications (Telegram, WhatsApp), settings are often inside the apps themselves. Go to the settings of a particular messenger, find the Notifications section, and change the sound there. If the app doesn't have that option, it will use the notification system sound that you set up in the main menu.
Some users prefer complete silence at certain times. In the Poco X3, you can set a schedule for Do Not Disturb mode. In this mode, the phone will ignore all sounds except those marked as important.
💡
System alarm sounds take precedence over No Sound mode, but can be turned off by Do Not Disturb mode unless exceptions are set up.
The solution: why not put a ringtone
Sometimes users are faced with a situation where the selected file is not displayed in the list or is not played, most often the problem lies in the access rights or file format. Modern versions of Android strictly monitor the permissions of applications.
Check if the Themes or Settings app has access to the device’s memory. Go to Settings → Apps → All Apps → File Manager (or Music) and make sure that permission to access media files is enabled.
It is also worth checking the bitrate of the audio file. Too high quality (for example, Lossless FLAC 24-bit/192kHz) may not be supported by a standard caller, in which case the file should be converted to a standard MP3 320 kbps or 128 kbps.
⚠️ Note: If the file is on the memory card SD, Make sure it's mounted correctly, and when you pull the card out, the ringtones that are set off will stop working, and the phone will return to normal sound.
In rare cases, cleaning the cache of the Themes app helps. To do this, go to the application management and click Clear the cache. Don't confuse it with cleaning the data so you don't lose downloaded themes.
