How to completely disable the T9 on Xiaomi Mi 9T: 5 proven ways

Owners of the Xiaomi Mi 9T often encounter the annoying T9 auto-replace feature, which automatically “fixes” words, adds spaces in uncomfortable places or substitutes the wrong emoji. This is especially annoying when entering technical terms, nicknames in games or non-standard words. In this article, we will examine all the current ways to disable the T9 on the Mi 9T – from basic keyboard settings to radical methods using ADB and third-party applications.

It is important to understand that MIUI is regularly updated and menu items may vary depending on the firmware version (12, 13 or 14).We have taken these nuances into account and prepared universal instructions that work on all current builds. If standard methods do not work, there are alternative solutions in the article, including resetting the keyboard settings and even replacing the system application.

Before you start, check your firmware version: go to Settings → About Phone → MIUI version. This will help you follow the instructions more accurately. Also note that some methods require root rights or a PC connection, we will warn you about this in advance.

1. disable T9 through standard keyboard settings

The easiest way is to use the built-in Gboard options (if installed) or Xiaomi's standard keyboard. Even if you've never changed the keyboard, the Mi 9T can default to one of these two.

First, determine which keyboard is active:

1. Open any input field (such as notes or a message).
2. Press the gear icon (⚙️) three-point (⋮) keyboard.
3. If you see the Google logo, you have Gboard; if the Mi icon is the standard Xiaomi keyboard.

Now follow the instructions for your keyboard:

For Gboard (Google keyboard):

• 📱 Open the Settings. → System system → Language and input → Virtual keyboard → Gboard.
• 🔍 Select Correction of text.
• ❌ Turn off options: Auto-Replacement (most important point!) Automatic comma placement Show suggestions when entering
• 🔄 Reboot your phone to make the changes take effect.

For the standard Xiaomi keyboard:

• 📱 Go to Settings. → Additionally. → Language and input → Current keyboard → Settings of the Mi keyboard.
• 🔍 Find the text correction or prediction section.
• ❌ Disable: Automatic replacement Automatic addition of spaces Predicting the next word
• 🔄 Save the changes and restart the keyboard (just close all applications).

⚠️ Note: On some versions MIUI The 14th item "Auto-Replace" can be hidden in the sub-menu "Additional settings." If you do not find an option, try resetting the keyboard settings (more about this below).

2. Reset keyboard settings to factory

If the T9 continues to work despite the shutdown of all options, it is possible that the keyboard settings were damaged after the system update, in which case the factory reset will help.

For Gboard:

• 📱 Go to Settings. → Annexes → Application management → Gboard.
• 🔄 Press Warehouse. → Clear the data (this will delete all user dictionaries!).
• 🔧 Then go back to Gboard settings and turn off auto-replace again.

For the Xiaomi keyboard:

• 📱 Go to Settings. → Annexes → Application management → Mi keyboard.
• 🔄 Choose Clear Data and Confirm the Action.
• 🔧 After reset, reset the language and disable T9 in the Correction section.

Save the user dictionary (if necessary)

Remember the current language settings

Clear keyboard data in the application settings

Reboot your phone after resetting-->

After reset, the keyboard can temporarily work slower, which is normal, and after 1-2 days of use, it will “fit” to your type of printing, but without intrusive auto-replacement.

3. Installation of an alternative keyboard (SwiftKey, Fleksy)

If standard methods don't help, the radical solution is to install a third-party keyboard where the T9 shuts down in two clicks.The best options for the Xiaomi Mi 9T are:

After installing the new keyboard:

1. Activate it in Settings → System → Language and input → Virtual keyboard.
2. Turn off the old keyboard (Gboard or Xiaomi) so it doesn’t get in the way.
3. In the settings of the new keyboard, find the Auto Replacement section and turn off all options.

💡

Before removing the standard Xiaomi keyboard, make sure the new keyboard is running smoothly.Some system applications (like calls) may require a factory keyboard to enter.

Disable T9 via ADB (for advanced users)

If you’re willing to take drastic measures, you can disable auto-replacement at the system level with Android Debug Bridge (ADB), a method that works for MIUI 12/13/14 and doesn’t require root rights, but requires connecting your phone to a PC.

You'll need:

• 🖥️ Computer with installed ADB-driver.
• 📱 Included debugging by USB on Mi 9T (Settings → The phone. → Version. MIUI — Press 7 times, then return to Settings → Additionally. → For developers → Debugging by USB).
• 🔌 Cable USB (preferably original).

Instructions:

1. Connect your phone to your PC and open the command line (Windows) or terminal (Mac/Linux).
2. Enter the command to check the connection: Adb devices must appear serial number of your Mi 9T.
3. Use the command to disable auto-replacement in Gboard: adb shell settings put secure spell_checker_enabled 0 For the standard Xiaomi keyboard, use: adb shell pm disable-user --user 0 com.miui.mishare.connectivity Attention: The second command is not only disabling T9, But also some of the features of sharing data between Xiaomi devices, and only use it if the first command doesn't work.
4. Reboot the phone.

⚠️ Attention: Teams ADB If the keyboard starts to work incorrectly after execution (for example, the Russian layout is lost), return the default settings with the command: adb shell settings delete secure settings spell_checker_enabled

5. editing system files (requires root)

If none of the methods worked, and you have root rights, you can manually edit the keyboard configuration files, which is only suitable for power users!

You'll need:

• 📱 Xiaomi Mi 9T Unlocked bootloader and root rights (for example, through Magisk).
• 📂 File Manager with root access (e.g., Root Explorer or Root Explorer) FX File Explorer).
• ⚠️ Backup of the system (in case of errors).

Instructions:

1. Open the file manager and go on the way: /data/data/com.google.android.inputmethod.latin/shared_prefs/ (for Gboard or /data/data/com.miui.mishare.connectivity/shared_prefs/ (Keyboard for Xiaomi).
2. Find the settings.xml file and open it in the text editor.
3. Find the lines with the parameters: <boolean name="spell_checker_enabled" value="true" /> and replace value="true"="false".
4. Save the file, reboot the phone.

If the keyboard stopped working after editing, restore the original file from the backup or reinstall the keyboard via Google Play.

💡

Editing system files without a backup can cause keyboard or other functions to fail, and only use this method if you are confident in your actions!
