Smartphone personalization is not just a tribute to aesthetics, but a way to make interaction with the device more comfortable and recognizable. Owners of Xiaomi, Redmi and POCO often face a limited set of standard ringtones that sound the same to millions of users around the world. Replacing a boring system sound with a favorite song or an important audio clip helps instantly identify an incoming call without even looking at the screen.
The installation procedure can seem confusing because of the features of the MIUI shell or the new HyperOS. The system has a specific file structure and strict permissions for applications, which sometimes prevents you from simply selecting a file from the Downloads folder. However, knowing the right paths and algorithms of actions, you can adjust the sound for any event from a regular call to an alarm clock.
In this guide, we’ll take a look at all the available ways to replace audio files, including hidden features, contact management, and notification settings. You’ll learn how to get around system limitations and use any formats your Android smartphone supports.
Audio file preparation and format verification
Before you start settings, you need to make sure that your music file is in the right place and has a supported format. Android, which runs Xiaomi phones, most stable with MP3, M4A and OGG. If your music is recorded in lossless formats like FLAC or WAV, it can also play, but for system ringtones it is better to use compressed formats weighing up to 5-10 MB.
An important step is to place the file in the system-accessible directory. By default, the standard Explorer can hide the system folders, so it is recommended to use the built-in Explorer application or a third-party file manager with extended rights. The file should be stored in internal memory, not in the SD-map, as in new versions of HyperOS, access to external drives for system sounds is often limited.
⚠️ Note: Do not use audio files from DRM-protection (for example, tracks from streaming services in offline mode), the system will not be able to read them as a ringtone, since they are encrypted for a specific account and application.
For easy management, create a separate folder called Ringtones or Calls at the root of internal memory. This is not a strictly mandatory requirement, but makes it much easier to find the desired composition in the list of system sounds. If the folder already exists, just put your file there.
💡
Use audio editors on your phone to crop the composition. The optimal ringtone is 15-30 seconds, otherwise you may not hear the start of the call while the phone vibrates.
Installation of a melody on a common incoming call
The most common scenario is to replace the standard tune for all incoming calls. In the MIUI shell, this process has its own features that differ from pure Android. You don't always have to search for a file through the settings menu, often it is easier to use the direct path through the theme of the registration.
Consider the classic method through audio tuning, which works consistently on most firmware versions, from MIUI 12 to the latest builds of HyperOS. The action algorithm requires careful attention, because menu items may be called similarly, but lead to different results.
☑️ Installation algorithm through settings
Once you select a file, the system can suggest cropping it or damping it. It's a built-in theme functionality that allows you to tailor any track to Xiaomi standards. If you select a file from the system list, it will apply instantly. If you choose from memory, you may need to confirm permission to access media files.
There's also an alternative path that many users miss out on, and it's connected to the Themes app. Even if you don't plan to change your visual style, this tool is a powerful sound manager. Go to the user profile, select Melodies, and upload your track. This method ensures that the melody is indexed correctly by the system.
Set up individual calls for contacts
One of the most useful features is to set up a unique call for a specific person, which lets you know who is calling you without taking your phone out of your pocket, and in Redmi and POCO, you can do this in two ways: through the Contacts app or through the Phone.
The first method is more reliable. Open the Contacts app, find the right caller, and click on their name. In the menu that opens, select "Sound" or "Melody." Here you will see a full list of available ringtones, including those you previously set to a general call. Select the desired track and save the changes.
The second method is relevant if you use Google Contacts or sync with Mi Account. Sometimes menu items may differ depending on the version of the caller app. If you don't see "Sound", try clicking on the contact edit button (usually a pencil), and the field to select a tune will appear in the extended menu.
| Method of setting up | Availability | Difficulty | Note |
|---|---|---|---|
| Through the Contacts app | Tall. | Low. | It works well on all versions of MIUI. |
| Through the Phone app | Medium | Low. | Depends on the version of the call (Google/MIUI) |
| Through Google Account | Low. | Tall. | Requires synchronization and web interface |
| Through third-party applications | Medium | Medium | Requires additional permits |
Remember that if a subscriber calls you via messengers (WhatsApp, Telegram, Viber), the settings of the phone book will not affect him. For these cases, you need to configure notifications inside the messenger applications themselves, which also has the function of selecting the sound for specific chats.
Using the Themes app to upload sounds
Xiaomi’s Themes app is not just a wallpaper catalog, it’s a powerful system tool, and many users ignore it for standard settings, but it’s where deep customization of audio is hidden.
To add your music through this tool, open the app and go to the Melodies section. In the upper right corner, there is often a music note icon or menu that allows you to import local files. The system will prompt you to select tracks from the device's memory. After importing, the track becomes part of the system library.
⚠️ Note: When using the Themes app, make sure that the region in your phone settings is set correctly (e.g. Russia or India).In some regions (e.g. EU), theme store functionality may be limited, but importing local files usually works.
The advantage of this method is that the tunes that are downloaded in this way are available for selection in any other menu, including alarm settings and notifications, which creates a single ecosystem of sounds within your device.
What to do if the importation in Themes does not work?
Setting the notification sounds and alarm clock
Notifications and alarms are particularly noteworthy, and unlike a bell, it often uses short signals. For an alarm clock, it is important to choose a track with a rising volume or a sharp intro to ensure that you wake up.
The alarm clock is set up through the standard Watch app. Open the alarm tab, select an existing one or create a new one. Click on the current tune name. A player will open, where you can select Local or Select on the device from the top menu (usually three dots or All tabs).
For notifications (SMS, mail, system events), the path is through Settings → Sound and vibration → Notifications Sound. There is also a choice of system sounds and tracks you download, and it is recommended to use short, non-irritating sounds for notifications so as not to create unnecessary information noise during the day.
💡
For an alarm clock, it is better to choose tracks without a smooth start (fade-in), otherwise you risk sleeping while the volume slowly increases.
Solving common problems and errors
Despite the simplicity of the process, users sometimes face problems: no melody is played, no sound is quiet, or the file is not displayed in the list, most often the problem lies in the access rights or file format.
If you don't see your file in the list of available tunes, check its format. As mentioned earlier, MP3 is the most versatile. Also make sure the file is not write-proof and is not in a hidden folder (starting from a dot).In newer versions of Android 13/14, file system access is limited, so moving the file to a Music or Ringtones folder often solves the visibility problem.
Another common mistake is “quiet call.” This may be due to the Pocket Mode or Smart Alarm settings, which mute the sound if the phone is down speaker or in the bag. Check these settings in the Sound and Vibration section → Additional audio settings.
⚠️ Attention: If after setting the melody, the phone starts to run slower or the sound is interrupted, it is possible that the bitrate of the audio file is too high for the decoder in the background. MP3 128-192 kbps.
In rare cases, cleaning the cache of the Themes or Sounds app helps. Go to Settings → Apps → All apps, find the system audio app, and click Clear Cache. This won't delete your files, but update the media content database.
