Modern smartphones, especially Xiaomi devices, offer users a huge opportunity to customize the interface and system functions. One of the most popular settings is changing standard notification sounds, since factory tunes often seem boring or too quiet. Personalizing the audio response helps not only express individuality, but also respond faster to important messages, instantly distinguishing them from information noise.
The process of changing the ringtone on the shell of MIUI or the new HyperOS has its own features that can confuse a beginner. Android security system and the company’s policy dictate certain rules for working with media files. In this guide, we will discuss in detail all the ways to install your tunes, including system settings, using themes and working with third-party applications.
To successfully complete all operations, you do not need superuser rights or complex technical knowledge, just a basic understanding of the file system of the smartphone and having the desired audio file in the memory of the device, we will look at the nuances for different versions of the operating system, so that the instruction is relevant to owners of both old and new models.
Preparation of audio files and file system
Before you start setting up your smartphone menu, you need to make sure that the audio file itself is ready to use. The Android system that powers Xiaomi phones has a strict folder structure for multimedia content. If you download music from the Internet or transfer it from your computer, it may lie in an arbitrary directory, and the system simply will not see it in the list of available ringtones.
To properly display the melody in the system notification list, the file must be in a special directory, usually a folder called Notifications or Notifications in internal storage, and if it does not, it can be created manually using any file manager, such as the standard Explorer from Xiaomi or the more advanced File Manager+.
The most versatile and supported format is MP3. While modern versions of MIUI can play AAC, OGG or WAV, MP3 ensures compatibility with all messengers and system services without the need for conversion.
💡
If you download the ringtone through the browser, save it immediately to the Download folder, and then move it to Notifications through the Explorer so as not to get confused in the files.
The length and size of the file should be considered. The system may crop or not play the entire tracks too long as a notification; the optimal duration for a message is 5 to 15 seconds; this is enough time to hear the beginning of a melody, but not too long to annoy others or block important system sounds.
Installation of system melody through sound settings
The easiest and most reliable way to change the sound of incoming SMS and system notifications is to use the regular settings menu, which works consistently on all versions of firmware, whether it is the old MIUI 12 or the latest HyperOS. The algorithm is extremely simple, but the paths can vary slightly depending on the localization.
To start, open the Settings app and look for the Sound and Vibration section. In some versions of the shell, this item may be simply called "Sounds." Inside, you'll see a list of all the audio events: calls, alarms, lock screens and, of course, notifications. We're interested in the Notifications or Default option.
Once you click on the appropriate item, you will see a list of available tunes. You may already have preinstalled tracks from Xiaomi. To select your file, you need to scroll down the list and click on the "Select music on the device" or the "+" icon. The file manager will open where you need to find the previously prepared track.
- 🎵 Open Settings and go to Sound and Vibration».
- 🔊 Select Notifications to change standard SMS sound.
- 📂 Click “Select Music on Your Device” at the end of the tone list.
- ✅ Find and confirm the selection of the desired audio file.
Once the file is selected, the system will automatically apply the changes, and any system notification or message from applications using the standard alert channel will be heard from the composition you select, a basic level of customization that covers most use cases.
Customize individual sounds for contacts and applications
One of the strengths of Xiaomi smartphones is the flexibility to customize notifications for each application and even for specific contacts separately, which allows you to know at the first sound who is writing or which application requires attention without looking at the screen.
To adjust the sound of a particular contact, open the Contacts app or Phone app, find the right subscriber on the list and go to their card, there should be a notification or rington button, and by clicking on it, you can select a unique tune for that person, which is especially useful for highlighting calls from close relatives or supervisors.
The situation is a little more complicated with messengers, because each of them has its own internal settings. However, MIUI allows you to manage notification channels at the system level. Go to Settings → Notifications and Status bar → Notification Management. Find the desired application (such as WhatsApp) and click on it.
⚠️ Note: In new versions of Android and MIUI The sound settings inside the app itself can be overridden by the system settings. If you change the sound in the phone settings, but the app has "No Sound" or a melody, the app's customization will work.
Inside the notification management menu of a particular application, you will see a list of categories (channels): “General”, “Group messages”, “Calls”, etc. By clicking on the category text (not on the switch), you will be taken to the detailed settings where you can set a separate sound, turn on the vibration or make a pop-up notification.
☑️ Setup of messenger notifications
So you can make messages from one Telegram contact sound like a siren and from another like a quiet bell, which takes time to set up initially, but in the long run, greatly improves the efficiency of interaction with the smartphone.
Use of the theme and theme store MIUI
The MIUI theme store is not only a way to change icons and wallpaper, but also a powerful tool to change the device's sound palette. Many authors create complex themes that include unique sets of system sounds that are not found in standard settings.
To use this feature, open the Themes app. In the search bar, type in a query like “sounds,” “audio,” or “notification.” You’ll see a lot of themes that specialize in sound. When choosing a topic, pay attention to the description: it usually indicates which sounds change (calls, SMS, system clicks).
Once you download and apply the theme, the old sounds will be replaced with new ones. If you only liked the notification sound and the rest of the theme doesn't fit, you can go for a trick: Apply the theme, copy the audio file you like from the theme system folder to your Notifications folder through the file manager, and then return the standard theme.
| Type of resource | Pluses | Cons | Difficulty |
|---|---|---|---|
| Standard settings | Stability, simplicity | Limited choice | Low. |
| File manager | Any MP3 file | We need to look for the file. | Medium |
| The shop that | Professional sounds | Change the entire interface | Medium |
| Third-party annexes | Automation | Advertising, access | Tall. |
The use of themes is especially relevant for those who want to completely change the acoustic experience of using a smartphone, making it more enjoyable or, conversely, more noticeable.
Solving problems with the reproduction of notices
Even after you set it up properly, users may find themselves in a situation where the sound is not playing, and most often the problem is not the melody itself, but the aggressive MIUI energy saving system or the conflict of profiles. If the phone is in Do Not Disturb or No Sound mode, the notifications will come, but the silence will remain.
Check the sidebar (curtain) to make sure that no vibration mode or silent mode is activated, and it is also worth checking the sound profile: there is a profile switch (Normal, Silent, Vibration) in the Sound and Vibration settings. Make sure that you select "Normal".
Another common cause is the failure of the Sound and Vibration system service, which is where a simple reboot of the device helps, and if it doesn't work, maybe the file is corrupted or has an unsupported bitrate, and try replacing the track with another file that is known to work.
What if the sound is in the settings, but does not play?
In some cases, an antivirus or third-party memory cleaner may block the playback of files from certain folders.Try moving the audio file to the root of internal memory or to the standard download folder to eliminate access issues.
Advanced settings via engineering menu and ADB
For advanced users who lack standard tools, there are ways to deeply customize the audio system. However, be very careful: interfering with system files can lead to unstable device operation. We will only consider safe methods.
One option is to use apps to create your own ringtones from the music libraries already on the device, and apps like Ringtone Maker allow you to cut out the desired snippet, add attenuation effects, and set the result immediately as a notification sound, bypassing manual file copying.
Also worth mentioning is the possibility of using ADB (Android Debug Bridge) to replace system sound files if the standard interface doesn't allow you to do what you want, which requires a computer connection and drivers.
adb push my_sound.mp3 /system/media/audio/notifications/This command, for example, could replace the system notification file, but on modern versions of Android with a system partition in read-only mode, this will require unlocking the bootloader and superuser rights, which is not recommended for ordinary users for security reasons.
⚠️ Note: Do not try to replace system files in the folder /system without a full backup and understanding of the risks, an error can lead to a bootloop (cyclical reboot) of the phone.
The best and safest way is to use the regular music selection functionality, which is implemented in MIUI quite flexibly, it allows you to assign any tracks from memory without risking damage to the operating system.
💡
The safest and most effective way to change sound is to use the built-in music selection menu in the notification settings, without modifying the system files.
