Smartphone personalization is not just a matter of aesthetics, but also a way to instantly identify an incoming call without taking the device out of your pocket. Owners of Xiaomi, Redmi and POCO devices often face the desire to replace standard system sound with a unique composition or favorite track. However, the structure of the MIUI shell or the new HyperOS has its own features that differ from pure Android, which can cause difficulties for beginners when finding the desired menu.
The ringtone replacement process doesn't require root rights or complex software. All the necessary tools are already built into the system, whether it's using the built-in Themes app or the classic File Manager. Understanding the logic of how the file system works in new versions of the shell will help you quickly assign any audio file to an incoming call, notification or alarm clock.
In this guide, we will take a detailed look at all available methods for setting tunes, look at the nuances of working with file formats and solve common problems when the phone “does not see” the downloaded track. You will learn to customize individual calls for different subscribers and create complex sound profiles for maximum comfort using the gadget.
Audio file preparation and format verification
Before you start setting up your system, you need to make sure that your audio file meets the technical requirements of your smartphone. Xiaomi supports most popular formats, but for stable operation it is better to use standard codecs. The most versatile and recommended format remains MP3, which is guaranteed to play as a call on any device without conversion.
If you downloaded music from the Internet, it can be in the formats of FLAC, WAV or M4A. Although modern Snapdragon and MediaTek processors easily decode them, the system player of calls can sometimes ignore files with a high bitrate or non-standard sampling rate. To avoid problems with silence instead of a call, it is better to convert the track to MP3 with a bitrate of 128 to 320 kbit / s.
⚠️ Attention: Files from DRM-protection (bought from some online music stores) cannot be installed as a ringtone.The system will not be able to play protected content outside the official player application.
It is also important to pay attention to the length of the track. Too long songs can be cropped by the system or incorrectly displayed in the selection list. The optimal duration of the ringing melody is from 15 to 30 seconds, which allows you to hear the beginning of the track and identify the call without waiting for the end of the long introduction.
Where to store files for quick access
Installation of the melody through standard settings
The easiest and most reliable way to change the sound for all incoming calls is to use the built-in settings menu, which ensures that the system correctly applies the changes and saves them after the reboot. First, unlock the screen and go to the main application menu.
Find and open the Settings app. Depending on the version of your shell (MIUI 12, 13, 14 or HyperOS), the interface may vary slightly, but the logic remains the same. You need to find the partition responsible for the sound.
- 🎵 Scroll down the list and select Sound and Vibration.
- 📞 Click on the Call Melody (or Rington) section. Don't confuse it with Notification Sound, which is responsible for messages.
- 📂 In the list that opens, select “All Melodies” or an icon «+», to open access to files on the device.
The system will offer you an application to select a file. The standard choice is File Manager or Sound Recording. Go to the folder where your prepared track is located (usually Download, Music or the Ringtones folder you created), tap the file you want, and it will immediately play back for verification.
☑️ Pre-installing check
Once you hear the track, click OK or the box in the corner of the screen, the system will confirm the application of the settings. Now, any incoming call from a number not entered in contact with the individual setting, will sound the selected composition.
Using the Topics app to search for ringtones
Xiaomi’s ecosystem preinstalled a powerful Theme app that serves not only to change wallpaper, but also to find quality audio content.This is the (official) source where tunes are already optimized for the brand’s smartphone speakers and do not require manual downloads from questionable sources.
Run the Themes app and find the Melody (or Ringtones) tab at the bottom of the screen, and it's a huge catalogue of genres, pop, rock, electronic music, classics, even sounds from games or movies, and you can listen to a preview of each track right in the catalog.
| Category | Description | Feature |
|---|---|---|
| Popular. | Trend hits of the current season | Frequently updated |
| Classic. | Standard MIUI sounds and classical music | Easy to perceive |
| Nature. | The sounds of wood, water, birds | Perfect for the "Do Not Disturb" mode |
| Effects. | Sounds from games, movies, memes | For an original approach |
When you select a composition you like, click Download (usually arrow down). After downloading, the button will change to Apply. This method is good because the file is automatically saved to the correct system folder, and you do not need to search for it in the file system.
💡
Use a tag search in the Themes app to find ringtones from specific movies or games by entering their name in the search bar inside the melody section.
Set up individual calls for contacts
One of the most useful features is the ability to assign a unique tune to a particular subscriber, which allows you to know who is calling you without taking your phone out of your pocket, and you can do this in two ways: through the contact menu or through the audio settings.
The first way is through the Contacts app or Phone. Open a contact list, find the right person, and click on their name to open the card. At the top of the screen or in the three-dot menu (or edit icon), find the Melody of the Call. The system will suggest you select a track from the standard list or files on the device.
The second is if you want to make calls to a group of people or set up complex rules. However, in its pure form, Android and MIUI tie the ringtone to the contact card. If the number is written twice or has different formats (for example, +7 and 8), make sure that the setting is applied to the main number.
⚠️ Note: If you change your SIM card or phone number, your personal settings may be lost if the contact was linked to an old number, not a Google or Mi Cloud account. Always check the relevance of contacts after data migration.
For users of two SIM-The system allows you to assign different tunes to the first and second SIM, but the individual contact melody usually takes priority over the SIM card settings, which means that if the contact is given its own sound, it will sound regardless of which SIM the call is received.
Working with File Manager and Hidden Folders
Modern versions of MIUI and HyperOS have tightened security and limited direct access to system folders, but advanced users can copy files directly to system directories so they can be displayed in a list of standard tunes without unnecessary action.
Open the Explorer app (or download Files by Google/MiXplorer from Google Play). You need to go to internal storage. The path to system ringtones usually looks like this: /MIUI/ringtone or /android/media/ringtone. However, direct copying there may require additional permissions.
A simpler and more efficient method is to create your own folder structure. Create a folder with a name at the root of your internal memory. My_Ringtones. Put your tracks in there. Then, when you select a tune through the settings (Settings). → Sound and vibration → Call melody, select the source of Files or File Manager and go to this folder.
Recommended folder structure:
/Internal memory/
├── Music/ (for player)
├── Ringtones/ (for system calls)
├── Notifications/ (for notifications)
└── Alarms/ (for alarm clock)If you don't see the music folder in the selection menu, the media scanner may not have updated the database yet.Try to restart your smartphone after copying files.Also make sure the files are not hidden (not starting from a dot) and have the correct ID3 tags (track name, artist), otherwise they may appear as "Unknown."
The Solution: Why the Melody Doesn't Work
Sometimes users are faced with a situation when after installing the track, the phone is silent or plays a standard horn. The most common reason is the on mode "Do not disturb" or "Silent mode." Check the side control panel (swipe down from the top corner) and make sure that the bell icon is not crossed out.
The second reason is the file format or the file damage, and if the track is downloaded from an untested source, it can be broken. Try opening it in any music player. If the player doesn't read it, the system bell can't, and the problem can be volume: in the sound settings, check the slider's volume, it shouldn't be at a minimum.
- 🔇 Check if the In-pocket mode is activated with a sensor error that can jam the sound.
- 📵 Make sure that there is no sound ban for a particular contact group.
- 🔄 Restart your device after installing new fonts or themes that may have changed system sounds.
💡
In 90% of cases, the problem is solved by a simple smartphone reboot, which forces the media service to re-scan the file system and update the list of available ringtones.
If the sound is gone completely (even system clicks), it may be damaged speaker or lost settings audio codec, in this case, will help reset the sound settings to factory values in the menu Settings → Advanced settings → Restore settings (the path may vary depending on the model).
