How to completely disable the T9 on Xiaomi Redmi 9: from keyboard to system settings

Why T9 Auto Replacement Is Irritating to Redmi 9 Users – and How to Fix It

The automatic text correction (T9) on Xiaomi Redmi 9 smartphones is often a source of frustration. The system stubbornly replaces rare words with “right” options, ignores jargon or professional terms, and sometimes even distorts your own names. The problem is compounded by the fact that MIUI is integrated by default with Gboard (keyboard from Google), where auto-replace settings are hidden deep in the menu.

In this article, we will look at all possible ways to disable the T9, from basic keyboard settings to radical methods using ADB. Particular attention will be paid to the nuances of the Redmi 9 firmware, where some options may be missing or work differently than on pure Android. If you are tired of the fact that the smartphone is “smarter” than you – read on.

We warn you right away: some of the methods will require administrator rights or debugging over USB. But don’t worry – we will explain each step in detail so that even a beginner can cope without risking “bricking” the device.

Method 1: Disable Auto Replacement in the Standard Gboard Keyboard

Most Redmi 9s have a default Gboard (Google Keyboard) setting that allows you to flexibly configure or disable the T9 completely.

1. Open any application to enter text (such as Messages or Notes).
2. Tap the input field to make the keyboard appear.
3. Click on the icon. ⚙️ (gear) in the top row of the keyboard - this will call the settings menu Gboard.
4. Select Correction of text → Auto-replacement.
5. Move the slider to the off position.

But that's not all, so to completely remove the smart cues, you have to turn them off.

• 🔹 Show sentences (same section Correction of text)
• 🔹 Automatic comma placement (if it interferes with the system)
• 🔹 Showing stickers and GIF (in the section Proposals)

Important: After this manipulation, the keyboard will become "stupider", but it will stop distorting your text. If you need hints, but only for individual words, add them to the Personal Dictionary (Dictionary section in Gboard settings).

Method 2: Use alternative keyboards without T9

If standard settings don’t help, consider installing a third-party keyboard, and some apps don’t have aggressive auto-replacement or allow you to flexibly configure it.

To install an alternative keyboard:

1. Download the application from the table above.
2. Go to Settings → System → Language and input → Virtual keyboard.
3. Activate the new keyboard and set it by default.

Tip: After installing a new keyboard, check its settings – some applications (such as Hacker’s Keyboard) require manual layout adjustment and disabling auto prompts.

Method 3: Disable T9 via MIUI settings (for Xiaomi system keyboard)

If your Redmi 9 doesn't use Gboard, but your MIUI keyboard, the algorithm will be different. Xiaomi's system keyboard is less flexible, but you can also turn off auto-replace it.

Instructions:

1. Open any text field and call the keyboard.
2. Then, click and hold the comma (,) in the lower row, then select the ⚙️ (setting).
3. Go to Correction of text.
4. Turn off the options: 🔹 Auto-replacement 🔹 Automatic arrangement of punctuation marks 🔹 Predicting the next word

In some versions of MIUI (especially on Redmi 9 with firmware for China), these options can be hidden deeper.

1. Go to Settings → Additional → Language and input → MIUI keyboard.
2. Select the advanced settings (if any).

Critical note: On some versions of MIUI 12/13 for Redmi 9, the option to disable auto-replace may be blocked, in which case only installing a third-party keyboard or the ADB method will help (see Method 5).

Method 4: Resetting a personal dictionary and learning a keyboard

Sometimes the problem isn't with auto-replacement, but with the dirty dictionary that the keyboard has accumulated over time, and if the T9 replaces words with meaningless options, try resetting the dictionary.

For Gboard:

1. Open the keyboard settings (see Method 1).
2. Go to the dictionary. → Personal dictionary.
3. Click on the language (such as "Russian") and delete all unnecessary words.
4. Go back and select Clear Learning Data.

For the MIUI keyboard:

1. Go to Settings → Additional → Language and input → MIUI Keyboard → Dictionary.
2. Remove all the words added manually.
3. Find the option to Reset Settings or Clear Data (reboot may be required).

Once reset, the keyboard will start learning again, to speed up the process.

• 🔹 Manually add frequently used words to the dictionary.
• 🔹 Turn off syncing the dictionary with your Google account (if you don’t need to).
• 🔹 Use the keyboard in the usual messengers 10-15 Minutes are enough for basic training.

💡

If the T9 dictionary continues to replace words after reset, try adding "problematic" words to your personal dictionary marked "Always substitute." For example, for "lorempsum" (which is often replaced by "lorem ipsum"), create a entries in the dictionary with the original spelling.

Method 5: Radical T9 shutdown via ADB (for advanced)

If all previous methods have failed, the last option is to disable auto-replacement at the system level using ADB (Android Debug Bridge), which requires connecting the smartphone to the computer and enabling debugging mode.

Warning: Incorrect ADB commands may disrupt the system. Follow the instructions carefully.

⚠️ Attention: Before executing commands ADB Make sure Redmi 9 is debugging enabled USB (Settings → The phone. → Version. MIUI — Tap 7 times, then go back to Settings → Additionally. → For developers → Debugging by USB).

Steps:

1. Download and install Platform Tools on your computer.
2. Connect Redmi 9 to your PC via USB-cable.
3. Open the command line (Windows) or terminal (macOS/Linux) in the adb folder.
4. Enter the commands in turn: adb devices (should appear your device) adb shell settings put secure spell_checker_enabled 0 adb shell settings put secure text_correction_enabled 0 adb shell settings put secure next_word_prediction_enabled 0
5. Reboot your smartphone.

These teams will shut down:

• 🔹 Spelling check (spell_checker_enabled)
• 🔹 Automatic correction (text_correction_enabled)
• 🔹 Predicting the next word (next_word_prediction_enabled)

💡

The ADB commands are system-level, so once they are done, auto-replace will be disabled for ALL keyboards, including third-party ones. To get it back, replace the 0 by 1 commands.

If the T9 is still working after the restart, try to do the following:

adb shell pm disable-user --user 0 com.google.android.inputmethod.latin

This command will disable Gboard completely (an alternative keyboard will be required).

Method 6: Roll back firmware or reset to factory settings (extreme case)

If the T9 auto-replacement became unbearable after the MIUI update, and no settings help, consider rolling back the firmware or resetting the device. This is a radical method, but sometimes it saves from the system keyboard bugs.

Important: Before resetting, make a backup copy of the data!

Resetting instructions:

1. Go to Settings → About Phone → Backup and Reset.
2. Select Settings Reset.
3. Confirm the action (a password will be required).

If the problem has occurred after the MIUI update, you can try to roll back to the previous version:

1. Download the necessary firmware from the official Xiaomi website (link).
2. Go to Settings → About the phone → System update.
3. Click on the three dots in the upper right corner and select Select the firmware file.
4. Specify the downloaded file and wait for the process to be completed.

⚠️ Note: Firmware rollbacks can cause data loss and unstable device performance if you choose a version that is incompatible with your region!

Frequent Mistakes and How to Avoid Them

When you turn off the T9 on Redmi 9, users often face typical problems, and here are the most common ones and how to solve them:

If none of these methods worked, maybe the problem is the firmware itself.

• 🔹 Contact Xiaomi Support with a description of the problem.
• 🔹 Try reflashing the device via Fastboot (for power users only!).
• 🔹 Install custom firmware (like LineageOS), but this voids the warranty.
