Smartphone personalization is not just a nice bonus, it’s a way to instantly recognize your device in a noisy company or at work. Owners of Xiaomi and Redmi devices often face the need to change the standard, well-known melodic signal to something more unique. The MIUI shell or its modern counterpart HyperOS provide ample opportunities for customization, but finding the right switches the first time can be difficult.
The process of replacing an audio file for incoming SMS or messenger messages requires understanding the structure of the settings menu. Unlike some other manufacturers, Chinese engineers have put sound control in a separate, detailed section, where you can control the volume, vibration and signal type for each application individually, giving you complete control over the acoustic behavior of the gadget.
In this article, we will take a look at all the steps of setting up, from choosing a standard ringtone to installing your own track from the device’s memory. You will learn how to bypass system limitations if the desired file is not displayed in the list, and what to do if the sound is lost after the update.
Basic setting of system sound SMS
The standard algorithm uses built-in tools from the Android operating system, and you first need to go to the main settings menu, where you have all the parameters of the device, and it's the central control place, where you change the parameters of the screen, the network, and of course, the sound.
Go to Settings and find Sound and Vibration, and that's where all the volume sliders and the lists of available tunes are concentrated. The system offers a few preset options that you can listen to before you install. The specific file is selected through the built-in audio player that is activated when you click on the track name.
- 🎵 Open Settings and select the Sound and Vibration section.
- 🔊 Find the Sound. SMS or the sound of the notification on the list.
- 📂 Select your favorite tune from the list or click + file-in.
- ✅ Confirm the choice by pressing the OK button or tick.
It is important to note that newer versions of the HyperOS shell may have slightly different interfaces, but the logic remains the same. If you don't see "SMS Sound" right away, try tapping the gear next to the notification volume slider - often the detail settings are hidden there. Also make sure that the notification volume slider is not kept at a minimum, otherwise even the loudest track will be barely audible.
💡
Use short audio files (up to 10 seconds) for notifications so they don’t get cut off abruptly and annoy others in quiet places.
How to set your tune from your phone memory
A standard set of ringtones often seems boring, and many users want to play their favorite track. mp3-The file in the music folder is not enough – the system MIUI requires the correct location of files to be seen in the list of available notifications.
To start, download the audio file you want, or create it with a voice recorder. Then open the file manager, like the standard Xiaomi Explorer. You need to move the file to a special directory. The path can look like internal memory → MIUI → sound → notification. If there is no notification folder, create it manually (the name should be in English and lowercase).
/storage/emulated/0/MIUI/sound/notification/Once you move the file, restart your smartphone or simply reopen your audio settings. The system will scan the folder and display your track in the general list. If the file is too high quality or non-standard codec, the system can ignore it, so it is better to use MP3 or M4A formats with a bit rate of up to 320 kbit / s.
☑️ Checking the melody file
⚠️ Note: Do not place notification files in the ringtone folder if you want to use them specifically for SMS. The ringtone folder is designed for incoming calls, and the system will search for notification files strictly in the notification directory.
Customization of individual sounds for contacts
One of the most useful features in Android is the ability to assign unique tunes to specific subscribers, which allows you to know who is texting you without even taking your phone out of your pocket. On Xiaomi and Redmi smartphones, this feature is implemented through the Contacts or Phone app.
Open a contact list and select the person you want to use. In your subscriber card, find Ringtone or Message Sound. When you click on it, you'll be taken to the same tune selection menu as the general settings. When you select a unique track, you'll make sure that the message from that person sounds different than everyone else.
| Parameter | Description | Where to find out. |
|---|---|---|
| General sound | Valid for all unknown numbers | Settings → Sound |
| Sound of contact | Individual for the selected person | Contacts → Card → Rington |
| Sound of the app | It is set up inside the messenger itself. | Application settings → Notifications |
It is worth considering that if a contact has several numbers saved, the setting can be applied to all of them or only to the main one, depending on the version of MIUI. Also, synchronizing contacts through Google Account sometimes resets individual settings if the other device was standing standard values, in which case the setting will have to be repeated.

Customization of sounds in popular messengers
In today's world, classic SMS has been replaced by Viber, Telegram, WhatsApp and other messengers, each with its own notification settings that override the system, so you need to change the sound directly inside the app.
Consider a WhatsApp-based example: Go to a chat room with a specific person or to the general settings of the app. Find the Notifications section and select the Notification Sound. This will open the system melody selection box where you can select a track from your phone's memory if it's in the right folder. Similar to Telegram: Settings → Notifications → Sound.
- 📱 Open the settings of a specific messenger.
- 🔔 Go to the Notifications section.
- 🎼 Click on the item Sound or Melody.
- 💾 Select a file from the list or download a new one.
Special attention should be paid to access rights. If the sound does not change after choosing a melody in the messenger, check the permissions of the application. It must have access to Memory and Microphone (sometimes this affects the operation of the audio engine), MIUI also has an aggressive energy saving system that can block the playback of sound by background applications.
💡
Notification settings inside the messenger always take priority over the general system settings of Android sound.
The solution to the problem: why the sound does not work
Even with the right setup, users can experience a situation where messages are silent, and the first and most common reason is the activated Do Not Disturb mode, which blocks all audio signals except those marked as exceptions, and you can check the status in the notification curtain.
The second common problem is MIUI Optimization, or aggressive energy saving, which can put the message app to sleep, and it doesn't have time to play the sound when it arrives, so you go to the battery settings, find the Messages app, and select the No Limits mode.
Settings → Applications → All Applications → Messages → Battery → Without LimitsIt’s also worth checking if the silent mode on the physical switch (if your model has one) or the software volume slider is on, sometimes cleaning the Messages app cache through the application management menu helps. If the problem persists, try resetting the audio settings to factory.
⚠️ Note: If you use third-party themes, they may conflict with system audio profiles. Try switching to a standard theme in the Themes app to rule out software conflict.
Use of third-party applications for customization
If you don't have the built-in capabilities of Xiaomi, apps from the Google Play Market will come to your aid. There are many utilities that allow you to create complex notification profiles, change sounds depending on time of day or location. One popular tool is Zedge or Ringdroid.
Apps like Ringdroid allow you to not just select a file, but edit it: crop it, make it fade out, change the volume, which is especially useful for creating the perfect short signal from a long music composition, and after editing, the application will prompt you to install the file as a system sound.
When installing these programs, carefully read permission requests. They need storage access and, in some cases, rights to change the system settings of the sound; Do not give suspicious applications access to contacts or a microphone without urgent need; Use only proven high-rated utilities.
