How to change the sound of a text message Xiaomi Redmi Note 4

Smartphone personalization is not just a matter of aesthetics, but an important part of the interaction with the device, allowing you to instantly recognize the type of incoming notification. For owners of the Xiaomi Redmi Note 4, this process may not seem obvious due to the features of the MIUI shell, which is significantly different from standard Android. Many users find that standard settings do not allow you to immediately select the right track for messages, requiring additional actions.

In this guide, we will take a look at all the ways you can change the notification melody, from choosing from your built-in library to installing your own audio files. You will learn how to customize personal sounds for different contacts and what to do if the system ignores the file you choose. Understanding the file system structure in MIUI will help you avoid typical configuration errors.

Redmi Note 4, which is powered by a Snapdragon or Helio processor, has enough multimedia capabilities to play any audio format. However, the software limitations of the shell often hide simple functions behind several menu levels. We'll look at the action algorithms that are relevant for both global firmware and Chinese builds.

Standard Methods of Choosing Melody Through Settings

The most obvious way to change the notification sound is through the system settings menu, but in MIUI it is divided into several logical blocks. First, you need to open the Settings application and go to the section Sounds and vibrations. This is where the main audio options for all system events of your Xiaomi are concentrated.

In the list that opens, you'll find the Notifications item, which is responsible for standard system sounds. Clicking on this item will open a built-in audio player with a set of preset tunes. It's important to note that the choice here applies globally to all applications that use the standard notification channel, unless they have customized settings.

⚠️ Note: When choosing a system tune, make sure that the notification volume slider is not in the minimum position, otherwise you may not hear the selected track even when vibrating actively.

An alternative way to get to the settings you want is to use menu search, swipe down on your desktop to open the search bar, and type the word "notification." The system will prompt you to go to the desired section of the menu, Sound and vibration, which will save time searching in the depth of the settings.

Using the Themes app to upload sounds

A unique feature of Xiaomi’s ecosystem is the deep Theme app, which serves not only to change wallpaper and icons, but also acts as a powerful audio editor. To find a new sound for SMS, open the Themes app and go to the bottom menu by selecting the Sound tab. Here is a huge catalog of audio files, categorized.

To set the melody, find the track you like and press the download button. Once downloaded, the system will suggest setting it as a ringtone, an alarm clock, or what we need as a notification sound, which is good because the files are already optimized for duration and volume to work as signals.

Inside the app, there is also a Ringtones section where you can edit tracks: crop them, add attenuation effects or change the tone.This allows you to create a unique sound that will not be repeated by other users of Redmi Note 4. After editing, the file is automatically saved to the corresponding system folder.

💡

Use the “Preview” feature in the Themes app to hear how the track will sound as a short notification before installing it.

Install your own SMS sound through the file manager

If standard tunes don't work for you, you can use any MP3 or WAV audio file stored in your device's memory. To do this, open the standard Explorer file manager and find the downloaded track. Usually, these files are in the Download or Music folder.

Once the file is found, click on it and hold your finger until the context menu appears. In the action list, select Set as and then Notification Sound. The system automatically copies the file to the desired system directory and applies it, which is the fastest way for those who are used to manually managing files.

There is also a more reliable method to ensure that the melody is saved even after resetting or updating the firmware, by copying your audio file to the root of internal memory or to the root of the memory. SD-map into a specially created folder MIUI, And inside it, it's in the sound folder and then the notification folder: /MIUI/sound/notification/.

The way to manually set your sounds:


Internal memory → MIUI → sound → notification

Once you put a file in this directory, it will appear in the list of standard sounds in the settings menu under its original name, a technique that is especially useful if you want to synchronize a set of tunes between multiple Xiaomi devices by simply copying the contents of that folder.

Customization of individual sounds for contacts

One of the most useful features is the ability to assign a unique text message to a specific person, so you can get a sense of who is texting you without taking your phone out of your pocket, and to do that, open the standard Contacts or Phone app and find the entry you want in your phone book.

In the contact card, find the default Melody item (sometimes hidden under the "More" button or edit icon). Click on it and the standard audio selection menu similar to the system will open. Select any track from the list or click on the + icon to select a file from the device's memory.

It is important to understand that on the Redmi Note 4 with the MIUI shell, the settings may vary depending on the version of Android. In some cases, you need to go to the Messages app, open a dialog with a contact, click three dots in the corner and select the notification settings where the audio is anchored.

Comparison of sound installation methods

Different ways to set tunes have their advantages and disadvantages depending on your goals. Below is a table that will help you choose the best option for your situation on the Xiaomi Redmi Note 4.

Using a file manager is the fastest way to replace a single file, whereas copying to the MIUI system folder is ideal for creating a permanent set of sounds. The Themes app is best for those who like to change design often and look for new sounds in directories.

The solution: why does not work the sound of SMS

Even with the right setup, users may find themselves in a situation where messages are silent, most often the problem is Do Not Disturb mode or aggressive battery optimization, and check if the silent mode is activated in the notification curtain or on schedule.

Another common reason is that the messaging app is running in the background. MIUI is known for its strict power control, so it can kill the listening process. Go to Settings → Applications → Messages → Battery and select No Limits mode.

⚠️ Note: If you use a third-party SMS app (e.g. Google Messages or Textra), system audio settings may be ignored.

It's also worth checking if the silent mode is on at the physical level if it's supported by your firmware version, or if the notification volume slider is worth zero.Sometimes it helps to simply reboot the device, which resets temporary errors of Redmi Note 4 audio drivers.

💡

If the sound is gone after the system update, check the Messages app access rights to the memory and microphone, and reset the sound settings to the factory in a special engineering menu (code ##6484##), but do this only if you are confident in your actions.
