How to change the sound of the Xiaomi Mi 9T: 5 ways + error solving

Xiaomi Mi 9T (also known as Redmi K20 in some regions) remains a popular device even years after its release, thanks to its balanced features and flexible MIUI firmware. However, many users have difficulty trying to change the standard sound of notifications for SMS. Unlike calls where the settings are intuitive, SMS settings are often โ€œhiddenโ€ in the depth of the menu or completely absent in some versions of the shell.

In this article, you will find 5 proven ways to change the tune of SMS โ€“ from basic MIUI settings to using third-party apps and hidden Android features. We will also analyze common errors (for example, when changes are not applied) and give recommendations for choosing the optimal sounds for different scenarios. All instructions are relevant for Mi 9T on MIUI 12-14 and Android 10-13 versions.

1. Standard method: through MIUI settings

The most obvious method is to use built-in shell tools, but in MIUI, the path to SMS settings is not always logical, especially if you're used to "pure" Android.

  1. Open the Settings app (cog icon).
  2. Go to the section Sound and vibration.
  3. Select the default Notification (in some versions โ€“ Notification Sounds).
  4. Scroll down to the Message (or SMS) block and tap it.
  5. In the list that appears, select the desired melody from the standard options.

โš ๏ธ Note: Some of the Mi's firmware 9T The message may not be available, because MIUI combines SMS and messenger settings into one section, in which case move on to the next method.

To be displayed in the list, the melody should be no more than 30 seconds long, and the format should be.mp3,.ogg or.wav. Files with a bitrate above 192 kbit / s may not be played.

2. Alternative path: through the settings of the application โ€œMessagesโ€

If there is no texting option in the general audio settings, try changing the tune in the Messages app (or Google Messages if you use it).This method works on 90% of MIUI firmware for the Mi 9T:

  1. Open the Messages app.
  2. Tap the three-point menu (โ‹ฎ) top-right.
  3. Select Settings โ†’ Notifications.
  4. Activate the Sound switch (if it is switched off).
  5. Click on the current tune and select a new one from the list.

Important: If you use Googleโ€™s Messages app, the path will be different: Settings โ†’ Notifications โ†’ Notifications Sound, in which case the changes will apply to all messenger notifications, not just SMS.

How to remove the standard MIUI sounds?
To hide unnecessary system melodies, use a root file manager (such as Root Explorer) and rename files in /system/media/audio/notifications by adding the.bak extension to their names.

4 Manually Adding Sounds through File Manager

For advanced users, there is a way to add their sounds without third-party apps.

  • File Manager (e.g., Mi File Manager or Solid Explorer)
  • Audio files in.mp3,.ogg or.wav format (maximum duration โ€“ 30 seconds).

Instructions:

  1. Connect the Mi 9T to your PC or download the sounds directly to your phone.
  2. Open the file manager and go to the Internal Storage folder.
  3. Create a Notifications folder (if not) at the root of the storage.
  4. Copy your audio files there.
  5. Reboot your phone (required!).
  6. New sounds will now be available in the notification settings.

If the sounds donโ€™t appear on the list, check out:

  • ๐Ÿ“Œ File format (only supported.mp3,.ogg,.wav).
  • ๐Ÿ“Œ Duration (no more than 30 seconds).
  • ๐Ÿ“Œ Extra characters in the file name (use only Latin and numerals).
  • ๐Ÿ“Œ The folder should be located at the root of the storage, not in subfolders like Download or Music.

๐Ÿ’ก

Files in the Notifications folder are made available for all applications, not just SMS. To make the sound only used for messages, rename the folder to MIUI/Notifications (create the MIUI nested folder).
