Xiaomi Redmi 9 owners often encounter an annoying feature of the built-in keyboard β the aggressive T9 auto-replacement, which corrects words where it is not necessary, or offers ridiculous options. This is especially noticeable when entering names, technical terms or slang expressions. The problem is compounded by the fact that different versions of MIUI (12, 13 or 14) settings may be located in non-obvious places, and some parameters are hidden from the user.
In this article, we will discuss all possible ways to disable the T9, from the basic settings of the standard Xiaomi keyboard to radical methods using ADB and third-party applications. You will learn how to remove auto-replace completely or customize it to your needs, why some options can be blocked, and what to do if after the system update, the settings are reset.
Why is the T9 on Redmi 9 not working properly?
The problem with auto-replacement on Redmi 9 is related to the features of MIUI firmware and machine learning algorithms that Xiaomi has integrated into the system keyboard.
- πΉ Adaptive Dictionary: The keyboard analyzes your messages and βremembersβ frequently used words, but sometimes mistakenly attributes typos or jargon to errors.
- πΉ Regional settings: If the system specifies an incorrect language or region (for example, Russian (Ukraine) instead of Russian (Russia), dictionary T9 may offer irrelevant options.
- πΉ Update Conflict: After Major Updates MIUI (For example, from 12 to 13) keyboard settings may be reset or work unstable.
- πΉ Manufacturer restrictions: In some regional versions of the firmware, Xiaomi artificially blocks access to certain keyboard settings.
Interestingly, the problem is more common on budget models (including Redmi 9/9A/9C), whereas on flagships (such as Xiaomi 13), auto-replacement algorithms work more accurately. This is due to resource optimization: on weak processors (Helio G35/G80), the keyboard simplifies text analysis, which leads to errors.
Method 1: Disable T9 in the settings of the standard MIUI keyboard
If you use a built-in Xiaomi keyboard, the first thing you need to do is check the basic settings. Depending on the version of MIUI, the path may be slightly different, but the general scheme is this:
- Open any field to enter text (such as Messages or Notes).
- Touch the gear badge (βοΈ) on the keyboard to open its settings.
- Go to Text Enter β Auto-Replacement (or Spelling in new versions).
- Turn off the sliders: π Automatic corrections π Input tips π Adaptive input (if any)
In MIUI 14, some items may be called: Keyboard settings β Advanced β Autocorrect. If you donβt have options, your firmware version hides them (see spoiler below).

Method 2: Reset the keyboard dictionary (if the T9 "remembered" the errors)
If auto-replacement persistently corrects specific words (such as surnames or terms) that you often use but are missing from the standard dictionary, resetting user data will help.This won't disable the T9 completely, but will clear the keyboard's "learning":
- Go to Settings β Applications β Application Management.
- Find the MIUI Keyboard (or LatinIME for the English version) in the list.
- Open the Warehouse. β Clear the data.
- Confirm the action. Attention: this will delete all saved words and settings!

If the keyboard brakes after reset, restart the phone. In some cases, MIUI will incorrectly restore the keyboard cache after cleaning.
Method 3: Install an alternative keyboard (Gboard, SwiftKey)
If the standard Xiaomi keyboard does not give flexibility in settings, the best solution is to install a third-party.
| keyboard | Pluses | Cons | Reference |
|---|---|---|---|
| Gboard (Google) | Accurate auto-replacement settings, cloud dictionary, gesture support | Collects input data, sometimes brakes on weak devices | Play Market |
| SwiftKey (Microsoft) | Adaptive AI, supporting themes, predicting emojis | Closed to new users (Microsoft account required) | Play Market |
| AnySoftKeyboard | Open source, minimalist design | Less Functions, Weak Russification | Play Market |
To install and configure Gboard:
- Download the app from the Play Market.
- Start Gboard and follow the activation instructions.
- Go to Settings β System β Language and input β Virtual keyboard.
- Select Gboard as the default keyboard.
- In Gboard settings, turn off: π Autocorrection (section Correction of text) π Showing clues π Block offensive words (if it interferes with the)
Important: Once you install a third-party keyboard, the standard MIUI keyboard will remain in the system and consume resources. To turn it off completely, go to Settings β Applications β Application Management β MIUI Keyboard β Disable.
Method 4: Disable T9 via ADB (for power users)
If none of the above methods worked and auto-replace options are blocked, you can use ADB (Android Debug Bridge), which requires connecting your phone to your computer and basic command line knowledge.
Warning: Incorrect ADB commands may disrupt the system.
β οΈ Note: On some versions MIUI (especially Chinese teams ADB If you see a not allowed error after you type in the keyboard, this method will not work.
Instructions:
- Turn on Developer Mode on your phone: Go to Settings β About Phone β MIUI Version. Click on MIUI Version 7 times until the notification You become a developer appears!.

If the commands donβt work, try an alternative:
adb shell pm disable-user --user 0 com.miui.miservice/.systemui.keyboard.KeyboardSettingsActivityThis command disables the keyboard system module, but can cause other MIUI functions to malfunction.
Method 5: Manual editing of system files (root)
For root users, there's a radical method of editing keyboard configuration files, which is a risky way to do that, but it's guaranteed to disable all of the T9's features.
You'll need:
- π± Installed by Magisk or other root manager.
- π± Root-enabled file manager (e.g., Solid Explorer or Root Explorer).
- π± Backup of the system (required!).
Instructions:
- Open the file manager and go on the way: /system/usr/keyboard/config.xml or /data/data/com.miui.miservice/shared_prefs/keyboard_settings.xml.
- Find the lines with the parameters: <bool name="auto_correction_enabled" value="true" /> and replace true with false.
- Save the file and restart the phone.
β οΈ Warning: Incorrect editing of system files can lead to bootloop ( looped reboot).If the phone does not turn on after the changes, you will need to flash it through Fastboot.

If you don't have root experience, you better use other ways. The risk of damage to the system is too high.
What if the T9 returns after the MIUI update?
Many Redmi 9 users complain that after updating MIUI, the keyboard settings are reset, which is due to Xiaomiβs policy, which, when major updates (for example, from 12 to 13), resets some user settings βto factoryβ.
To avoid this problem:
- π Turn off automatic updates MIUI In Settings β The phone. β Updating the system β Settings (βοΈ) β Auto-update.
- π₯ Before manually updating, export your keyboard settings (if you have one) or take screenshots of your current configuration.
- π§ After the update, do not click βOKβ in the welcome window. MIUI β Go to the keyboard settings and restore the parameters.
If the update has already occurred and the T9 is back:
- Repeat the steps from Method 1 or Method 3 (with a third-party keyboard).
- If your settings are blocked, use ADB.
- In extreme cases, reset the keyboard settings (see Method 2).
