Call personalization is not just a matter of aesthetics, but also an important feature that allows you to instantly identify the caller without taking the phone out of your pocket. Owners of Xiaomi, Redmi and POCO devices often encounter the nuances of the MIUI or HyperOS shell, which hide the standard personalization features in the depths of the system menus.
Set up a unique tune for a particular subscriber requires understanding the logic of the built-in Contacts app and the Android file system. Unlike the global call change, customization requires additional steps that are not always obvious to the user.
In this guide, we’ll take a look at all the ways you can assign tunes, including system sounds and user’s own audio files, and learn how to avoid common mistakes when your phone is silent or playing a standard track instead of your chosen track.
Preparation of audio files and file system
Before you start setting up, you need to make sure your audiophile is physically in the right place.The Android system, and in particular the MIUI shell, has a strict folder structure, and if the track is in a random directory, the system may simply "not see" it when selecting a ringtone.
The ideal option is to move music files to the Ringtones root folder or MIUI/ringtones in the internal storage, ensuring that the track appears in the system sounds list, not just in the media player.
Use built-in Explorer or third-party managers like Total Commander to move files. mp3 File, click Copy and select the target folder at the root of internal memory.
⚠️ Note: Files downloaded from messengers (WhatsApp, Telegram) often have restrictions on reading by other applications. It is better to copy the desired track to a separate folder with music to avoid problems with access rights.
Support for formats also matters. While Android is universal, ringtones are best served with MP3s with a bit rate of at least 128 kbps. Formats like FLAC or WAV may not appear on the call selection list due to the limitations of the system audio engine.
💡
Use audio files that are no longer than 30-40 seconds long, and long tracks may be cropped by the system or playback incorrectly when an incoming call is made.
Configure through the standard Contacts app
The most direct and reliable way to set a tune is to use the built-in Contacts app, which works consistently on all firmware versions, from the old MIUI 11 to the latest HyperOS.
Open the Contacts app on the home screen or in the app menu, find the right caller on your list whose call you want to personalize, and click on their name to go to the contact card.
In the menu that opens, find the “More” button (usually three dots or horizontal bars in the corner of the screen) and select “Appoint a ringtone.” If there is no such item right away, it can be hidden under the “Change” button in the form of a pencil.
☑️ Algorithm of action
Once you select the item, you will open a system player where you can select a track from the list of standard ones or go to the "Music on the device" tab, and here you will see all the tracks that the system has recognized as suitable for calls.
Using the Phone app to assign melody
An alternative path lies through the Phone app, which is also part of Xiaomi's ecosystem.The interface may vary slightly depending on the shell version, but the logic remains the same.
Run the Caller and go to the Contacts tab at the bottom of the screen, find the right person and click on their name. In the profile that opens, look for the Sound section or the bell icon.
On some versions of MIUI, you must first press the edit button (pencil), scroll down to the Call Melody section and only there make a choice.
If you use Google Contacts for sync, changes made through the Phone app can sync with your Google account, allowing you to save the setting even after you change your device.
Why can't you see the edit button?
It’s important to note that the Phone app sometimes caches contact data. If you’ve just created a new contact, give the system a couple of seconds to index before trying to assign it a tune.
Contact management SIM-maps and Google
The location of the contact has a direct impact on the availability of functions. SIM-cards, have extremely limited functionality and often do not support the appointment of individual ringtones directly.
Modern Xiaomi smartphones recommend storing data in a Google account or in the Mi Cloud, which ensures full compatibility with all personalization features.
If your contact is retained SIM-The card, the system may suggest copying it to your phone memory or Google account. Consent to this action to access the full set of settings.
| Storage area | Rington support | Synchronization | Recommendation |
|---|---|---|---|
| Phone memory | Complete. | No (locally) | Not recommended |
| SIM-map | Limited/No | Hand-held | Move it to Google |
| Google Account | Complete. | Automatic. | The best choice |
| Mi Account | Complete. | Automatic. | For ecosystem users |
Check where the contact is saved by opening his card and looking at the top of the screen or in the "Information" section, which will indicate: "Save in: Google" or "Save in: SIM 1".
💡
For maximum compatibility and ringtone customization, always keep your contacts in your Google or Mi cloud accounts, not on your own. SIM-map.
Problem Solving: Why the Melody is Not Set
Often users are faced with a situation where after all the manipulations, the contact rings with a standard horn, one of the common reasons is the file format. If a track is protected by DRM (digital rights), for example, downloaded from a subscription streaming service, the system will not be able to use it as a ringtone.
The problem may also be in the permissions of the Contacts or Phone app to the storage. Go to Settings → Apps → All Apps → Contacts → Rights and make sure that access to files is allowed.
Another nuance is volume: Make sure that the audio profiles do not have "No Sound" or "Do Not Disturb" modes for unknown numbers if you are testing the setting on yourself.
⚠️ Warning: Once the firmware updates, ringtones settings for individual contacts may reset.This is a well-known feature of Android that requires re-manual adjustments.
If nothing helps, try removing the Contacts app cache.This won't delete the numbers themselves, but will update the database, which may solve the problem with the tracks display.
Customization through third-party apps and themes
The MIUI shell allows you to deeply customize the interface with themes. Some themes can change the standard call app to their own, in which case the ringtone settings should be searched inside the theme itself or returned to the standard application.
There are specialized applications from Google Play, like Contacts+ or Trustaller, that take over the management of calls, and if you use them, you need to assign tunes through their internal interface, not through system settings.
When using third-party “calls,” make sure they have “Run on top of other apps” permission and access to the phone book, otherwise personalization won’t work.
Third-party solutions are justified if the standard functionality of Xiaomi
