Smartphone personalization isn't just a matter of aesthetics, it's a way to instantly navigate the stream of incoming notifications without taking the device out of your pocket. Xiaomi Redmi owners often face the need to change the standard, intrusive message sound that sounds the same to millions of users around the world.The standard MIUI shell, or the new HyperOS, offers flexible tools to customize, but they're not always obvious at first glance.
The process of replacing an audio file depends on which application you use for correspondence: a standard “Messages” from Google, an embedded application from Xiaomi or a third-party messenger like Telegram. In this article, we will examine all possible scenarios, including the hidden nuances of the Android file system on the devices of the Chinese brand.
We will also discuss optimization, as improperly selected heavy audio files can affect the speed of the interface when the screen is locked. It is important to understand the difference between system ringtones and user tracks stored in memory.
Use of standard system settings
The easiest and most reliable way to change the notification sound is to take advantage of the built-in capabilities of the Android operating system. On Xiaomi smartphones, this path may vary slightly depending on the version of the shell, but the logic remains the same. You do not need special applications or superuser rights.
To start, open the main menu and find the Settings icon. Scroll down to the Sound and Vibration section. This is where all the options associated with audio events are concentrated. Note that in some versions of MIUI, this item may simply be called "Sounds."
Inside the menu, look for "Notifications" or "Notification Sound." When you click on it, you'll see a list of preset tunes. The system lets you listen to each option before you install it. Selecting a standard system tone ensures that the sound will play correctly even when the power saving mode is on.
If you want to just choose a different version from the one the factory has offered, this section is quite enough, but to install your own composition or track downloaded from the Internet, you need to perform additional actions, which we will talk about in the next sections. Standard kit is often boring and quickly boring.
💡
System settings are a basic level that does not require additional software installation and works stably on all firmware versions.
Install your melody through the “Themes” menu
The Xiaomi ecosystem is uniquely featured in the Themes app, which is not just a wallpaper store, but a powerful customization tool that allows you to change fonts, icons and, importantly for us, system sounds, and you can find quality audio files that are optimized specifically for the brand's smartphone speakers.
Run the Themes app on your desktop. At the bottom of the screen, search for the Sounds tab or search for SMS or Notification. The catalog offers thousands of options, from short signals to full-length music, many of which are created by independent designers and are not available in the standard set.
Once you have selected your favorite option, click Download and then Apply. The system automatically sets the selected track to the event, and the advantage of this method is that you don't have to search for files online and worry about formats - everything is already adapted for HyperOS.
- 🎵 Open the Themes app and go to the Sounds section.
- 🔍 Use keyword search to find style quickly.
- ⬇️ Download and apply the track, the system will assign it to SMS.
- 🔄 To return to the standard, simply select a different sound or reset the theme.
It's worth noting that some of the sounds in the theme store may be paid or require you to watch ads, and there's a subscription-based "Premium" category, but there's more than enough free content to find something unique to your Redmi.
Why is the sound not applied after the theme?
Setup via the “Messages” app from Google
Most modern Xiaomi Redmi smartphones use Google’s Messages app as their default SMS tool. It has its own audio settings that override the system. If you change the sound on the phone’s menu but it doesn’t change in the correspondence, the problem is here.
Open the Messages app. Click on the profile avatar in the upper right corner and select Message Settings. Then go to Notifications. Here you will see Notification Sound. Click on it and you will be in the system selection of ringtones, but only for this application.
It’s important to distinguish between settings for “New Messages” and settings for specific contacts. Android allows you to assign a unique sound to an important one so you can know who is writing without looking at the screen. To do this, open a contact chat, click three dots in the corner and select “Details”, then “Notifications and Sounds”.
⚠️ Note: If you use Do Not Disturb mode, SMS audible notifications may not play even if the tune is set correctly.
This method is most preferred for users who want to have different sounds for different types of messages or contacts.The Google Messages app updates independently of the system, so the interface may be slightly different, but the logic remains the same.
☑️ Checking the settings of Google Messages
Using your own MP3 file in memory
Often users want to play a clip from a favorite song or a funny sound from a movie that isn't on the standard list, and to do that, the file must be in MP3, OGG or WAV format and be in the phone's memory, and the installation process is a little more complicated, but it gives you complete freedom of creativity.
First, download or copy the audio file you want to use in your smartphone memory. You can prefer to put it in a folder that you can understand, like Downloads, or create a new Ringtones. Then go to Settings → Sound and Vibration → Notification Sound. At the bottom of the list, click the + or Add Sound button.
A file manager will open to find your track, and it will appear in the general list of available tunes after you select it, and if the add button is not active, try moving the file to the root folder or to the special MIUI/sound directory, although this is rarely required on new versions of Android.
| Parameter | Recommendation | Limitation |
|---|---|---|
| File format | MP3, OGG | WAV can take up a lot of space |
| Duration | 5-15 seconds | Long tracks can be cut off |
| Location. | Internal memory. | SD-The card may not be read when loading |
| Quality. | 128-320 kbps | High quality is not needed for the speaker. |
Using your own files allows you to create a truly unique profile of the device, but keep an eye on the file size: too heavy tracks in high resolution can cause micro-latency when playing a notification if the processor is loaded at that point.
💡
To create the perfect song, use online services or cutting apps to set the exact start and end times (fade-in/fade-out), Otherwise, the sound may break off sharply.
Solving Sound Problems on Xiaomi
Sometimes users are faced with a situation where text messages come, the phone vibrates, but there is no sound. This is a common problem in the shells of MIUI and HyperOS, associated with aggressive energy savings or conflict profiles. First of all, check if the silent mode is on.
Go to Settings → Sound and Vibration. Make sure the notification volume slider is not at zero. Also check the sound profile: it should be Normal, not No Sound or Vibration Only. Sometimes switching the profile back and forth helps.
The second common reason is the Security app and memory cleanup. The system can kill the sound playback process, considering it to be background load. Go to the Security app → Permissions → Autostart and make sure the Messages app has the necessary rights.
- 🔊 Check the physical volume with buttons on the case during the arrival of SMS.
- 🚫 Turn off the "Do Not Disturb" mode and check your sleep schedule.
- 📱 Reboot the device to reset the sound driver.
- 📂 Make sure the melody file is not corrupted and is supported by the codec.
⚠️ Warning: If the sound is gone after the system update, media rights may have been lost. Try reassigning the melody through the Sound and Vibration menu, even if the track is already there.
In rare cases, the problem lies in the dynamics itself: play music or video. If there is no sound anywhere, you need a diagnosis (hardware), but if the music is playing and the SMS is silent, it is solely the software settings of Xiaomi.
Secret to Quiet Notifications
Set up notifications for messengers (Viber, WhatsApp, Telegram)
It is important to understand the difference between classic SMS and messages from Internet messengers. Standard audio settings in the section “Sound and vibration” often do not apply to WhatsApp, Viber or Telegram, as they use their own notification engines.
For each messenger, the setting is done individually within the app itself. For example, on Telegram, you need to go to Settings → Notifications and Sounds → Message Sound. On WhatsApp, the path is similar to Settings → Notifications → Message Sound. Here you can also select the system track or add your own.
On the current versions of Android 11/12/13/14, which are installed on the fresh Redmi, notification channels allow you to flexibly adjust sounds for different types of events within the same application. Go to the phone system settings → Apps → All Apps → Choose Messenger → Notifications. There you can specify the behavior of the sound for each category.
This gives you a lot of flexibility: you can set up important messages from work to sound loud and persistent, and notifications from group chats to be quiet or without sound at all, and this granular setting is available thanks to the integration of MIUI with native Android features.
