How to permanently disable auto replacement on Xiaomi Redmi: 5 proven ways

Auto-replacement text on Xiaomi Redmi smartphones is often a source of annoyance: the system stubbornly corrects names, slang words or specialized terms for “right” options that you do not need. Despite the fact that the feature is designed to make typing easier, it often works against the user – especially if you use non-standard vocabulary, nicknames in games or professional slang.

Complicating the problem, Xiaomi’s MIUI hides some auto-replacement settings deep in the menu or doesn’t provide direct access to them at all. In this article, we’ll look at all the ways you can disable auto-correction from basic to advanced, including methods for different firmware versions and Redmi models (from Redmi Note 7 to Redmi 13 Pro).

Why is Xiaomi Redmi Auto Replacement Not Working?

The MIUI autocorrect function is based on three components:

• 📚 Built-in dictionary: contains thousands of words and rules for Russian, English and other languages. Updated with firmware.
• 🧠 Machine learning: The system remembers your frequently used words and “fixes” while adapting to the style of the set.
• 🔄 Xiaomi Cloud Services: Synchronize Data Between Devices and Offer “Smart” Editings Based on Big Data.

Problems arise from:

1. Conflict between a local dictionary and cloud sentences (for example, a word is added to exceptions, but the cloud still fixes it).
2. Errors in machine learning algorithms when the system “remembers” faulty patches (for example, if you once agreed to replace “lol” with “lol”).
3. Regional features: firmware for different countries have different vocabulary (in the European version there may be no support for Russian slang).

⚠️ Note: If you use a third-party keyboard (such as Gboard or SwiftKey), auto-replace settings may be duplicated, in which case you will have to disable the function in the system keyboard. MIUI, and in a third-party annex.

Method 1: Disable auto-replacement in standard keyboard settings

The easiest method is to use the built-in MIUI keyboard options, which is suitable for most Redmi models on MIUI 12/13/14:

1. Open any application where you can type text (such as Notes or Messages).
2. Tap the input field to make the keyboard appear.
3. Press the gear icon (⚙️) in the top row of the keyboard to open the settings.
4. Go to the Text Input section → Auto-replacement.
5. Turn off the sliders: 🔘 Automatic Replacement (main function) 🔘 Automatic spacer (if it interferes with the) 🔘 Double letter correction (e.g., “hello» → «hello»)

If your MIUI version does not have an Auto-Replacement option, try an alternative path:

Settings → Additional settings → Language and input → Current keyboard (MIUI) → Settings → Text input

Important: Some models (such as the Redmi 10 or Redmi Note 11) may need to restart the device after auto-replacement is disabled to make the changes effective.

Method 2: Reset the Auto-Replacement Vocabulary (cleaning up the trainable data)

If auto-replacement persists in correcting specific words (such as names or terms), even after the function is disabled, the problem lies in the dictionary being trained. The system has memorized your previous "mistakes" and continues to "fix" them.

1. Go to Settings → Applications → Application Management.
2. In the search bar, enter the MIUI keyboard (or Input Method in English firmware).
3. Select the application and click Storage → Clear the data.
4. Confirm action. Attention: This will delete all user words, including those added manually.

After discharge:

• ✅ Keyboard will stop offering “learned” fixes.
• ❌ All retained reductions will disappear (e.g., "PZ» → «Welcome»).
• ⚠️ You may need to reconfigure the input languages and the theme of the keyboard.

Method 3: Using ADB to Deeply Disable Auto Replacement

If standard methods don't work, you can use ADB (Android Debug Bridge) debugging, which is suitable for advanced users and requires connecting the phone to a computer, and the advantage of the method is that it allows you to completely block auto-replace functions at the system level.

For this:

1. Enable Developer Mode on Phone: Settings → About Phone → MIUI Version (click 7 times)
2. Activate USB Debugging in Settings → Additional settings → Developer settings.
3. Connect Redmi to the PC and execute the command to ADB: adb shell settings put secure spell_checker_enabled 0

Additional commands for complete shutdown:

⚠️ Attention: Teams ADB can disrupt the stability of the keyboard if entered incorrectly. Before using, back up the data through Settings → Additional settings → Backup and reset.

Method 4: Install an alternative keyboard (bypass system constraints)

If none of these methods worked, the radical solution is to completely abandon the MIUI keyboard in favor of third-party counterparts, such as Gboard or SwiftKey, which offer more flexible auto-replacement settings and are not subject to MIUI limitations.

How to switch:

1. Install an alternative keyboard from Google Play (such as Gboard).
2. Activate it in Settings → Language and input → Current keyboard.
3. In the settings of the new keyboard, turn off: 🔘 Autocorrection 🔘 Prediction of text 🔘 Automatic comma placement

Advantages of third-party keyboards:

• 🎯 More precise exception settings (you can add words to the whitelist).
• 🌍 Supporting multiple languages simultaneously without conflict.
• 🔄 Synchronize settings between devices through a Google account.

Disadvantages:

• ⚠️ Certain functions MIUI (For example, fast commands for Xiaomi applications may become unavailable.
• 📱 Increased battery consumption (third-party keyboards often work in the background).

💡

If you type in multiple languages often, you can set up gestures in Gboard to switch layouts, such as swiping your finger across a space to the left or right to change your language without pressing a button.

Method 5: Manual editing of system files (for power users)

This method is only suitable for unlocked bootloaders and requires root rights. It allows you to permanently delete files responsible for auto-replacement, but risks losing warranty and risking damage to the system.

Instructions:

1. Install Root Explorer or Solid Explorer with root support.
2. Cross the path: /system/usr/miui/dictionary/ It stores dictionary files for different languages (for example, dictionary_ru.dict).
3. Rename or delete files that are responsible for unnecessary languages (create a backup!).
4. Reset the device.

⚠️ Note: Deleting system files can cause a keyboard crash or a cyclical phone reboot.This method is only recommended if you are ready to flash the device in the event of a crash.

The alternative is to manually edit the dictionary files, removing unnecessary words from them.

• Copy the dictionary file on the PC.
• Open it in Notepad++ or another UTF-8-encoding editor.
• Remove the lines with unwanted substitutions (format: wrong = correct).
• Save the file and return it back to the /system folder by setting permissions 644 (r-w-r--r---).

Frequent problems and their solutions

Even after the auto-replacement is turned off, Xiaomi Redmi users face typical difficulties:

If none of these methods worked, try:

• 📥 Reverse to the previous version MIUI, If the problem occurs after the update.

💡

On Redmi models with global firmware (MIUI Global), auto replacement often works more aggressively than in the Chinese version (MIUI China). If the problem is critical, you can consider switching to Chinese firmware (requires unlocking the bootloader).
