Xiaomi’s MIUI-based smartphones offer a powerful auto-replacement tool that saves time when typing. However, many users face challenges: the system persists in correcting the right words, ignores the added terms or does not offer suitable options at all. In this article, we will examine all the nuances of auto-replacement settings on Redmi, POCO and Xiaomi devices, from basic parameters to hidden features that are not written in the official instructions.
The thing about MIUI is that auto-replacement works not only at the keyboard level, but also is integrated into system services, which means that even if you use a third-party keyboard (like Gboard), some of the fixes will be applied by the system itself, and we'll show you how to manage both levels to make auto-replacement work perfectly without annoying "fixes" where they're not needed.
Where is the auto replacement on Xiaomi: ways to set up
The auto-replacement setting on Xiaomi depends on the MIUI version and the device model. In recent versions (MIUI 14+), the path has changed, so we'll look at both options. If you have a POCO or Redmi with custom firmware, some menu items may not be available.
The main places where the settings are hidden:
- 📱 System keyboard MIUI: Settings → Additional settings → Language and input → Current keyboard (MIUI) → Settings → Text input → Auto-replacement
- 🔧 System services: Settings → System and device → Advanced settings → Language and region → Input of text → User's dictionary
- 🔄 Reset keyboard settings (if auto-replacement is not working correctly): Settings → Annexes → Application management → keyboard MIUI → Warehouse → Clear the data
On the POCO F5 and Xiaomi 13 with MIUI 14, the path is simplified: just go to Settings → Language and input → MIUI Keyboard → Auto Replace. But on older models like Redmi Note 8 (MIUI 12) you will have to dig deeper - sometimes the settings are hidden in Settings → System → Language and input → Virtual keyboard.
How to turn on or off auto-replacement completely
If auto-replacement is annoying with constant fixes, you can turn it off completely, but be careful, as well as useful features like automatic comma placement will also be turned off.
Step-by-step:
- Open Settings and go to Additional Settings → Language and Enter.
- Slip on the current keyboard (usually the MIUI keyboard).
- Select keyboard settings → Text input.
- Find the Auto Replace switch and move it to the off position.
- To completely disable, also deactivate Automatic Punctuation Arrangement and Text Prediction.
Some models (for example, Xiaomi 12T) have a separate switch “Typics Correction” – it is also worth turning off if auto-replacement is too intrusive.Remember: after disabling all the words you added to the user dictionary will remain in the system, but will not be used.

Adding Your Words to Auto Replacement
The most common problem is that the system persists in correcting unique names, slang, or professional terms, such as the word "MIUI" can be automatically replaced with "MUI" or "Miui." To avoid this, add problematic words to the user's dictionary.
How to do this:
- Go to Settings → System and Device → Language and Region → Text Enter → User Dictionary.
- Slip on Add (the icon "+" in the upper right corner).
- In the Word field, enter a term that you want to save (e.g., POCOPHONE).
- In the Short Form field, specify the abbreviation (if necessary).
- Press Save.
An important nuance is that if a word already exists in a system dictionary (e.g., "Redmi"), it cannot be overridden, and in such cases only completely disabling auto-replacement for a particular application (more on this in the next section) will help.
💡
To quickly add a word to the dictionary, type it in any text field, tap on the red-emphasized word and select "Add to the dictionary."
| Action. | The Way to MIUI 12 | The Way to MIUI 14 |
|---|---|---|
| Add a word to the dictionary | Settings → Additional settings → Language and input → User dictionary | Settings → Language and input → User dictionary |
| Turn off auto-replacement | Settings → Additional settings → Language and input → MIUI Keyboard → Settings → Text input | Settings → Language and input → MIUI Keyboard → Auto-replacement |
| Reset the keyboard settings | Settings → Applications → Application Management → Keyboard → Clear data | Settings → Applications → Application Management → MIUI Keyboard → Storage → Clean all data |
Set up auto-replacement for individual applications
Sometimes auto-replacement is needed in messengers, but it interferes with the browser or code editor, and MIUI allows you to flexibly manage these settings.
How to configure by application:
- Open Settings → Applications → Application Management.
- Select the application you want (such as Telegram or Chrome).
- Slip on permissions → Additional → Keyboard settings.
- Activate or deactivate Auto Replacement and Text Prediction.
On the POCO X3 Pro and other devices with MIUI 13+, this path may not be available.
- 📝 Open the app where you want to disable auto-replacement.
- 🔑 Call the keyboard and hold the icon with your finger. ⚙ (gear) in the top row.
- 🔄 In the menu that appears, select Keyboard Settings for [application name].
Restriction: Some system applications (e.g. Messages or Contacts) do not allow you to disable auto-replace selectively – the changes will apply globally.
Why Auto Replacement Doesn't Work in Some Apps
Correcting Typical Auto Replacement Errors
The MIUI auto-replacement system sometimes behaves in an unpredictable way, and here are the most common problems and solutions.
- 🔄 Words are replaced with the wrong options: Clear the keyboard cache in Settings → Annexes → keyboard MIUI → Warehouse → Clear the cache.
- 📛 Ignored words added to the dictionary: Remove a word from the dictionary and add it again using an exact register (for example, "MIUI", not miui").
- 🌍 Auto Replacement works only in English: Check what is in Settings → Language and input → Keyboard languages included Russian language.
- ⚡ Delays in text input: Turn off text prediction and key animation in keyboard settings.
If after the MIUI update, auto replacement stopped working, try resetting the keyboard settings:
Settings → Applications → Application Management → MIUI Keyboard → Storage → Clean all data⚠️ Note: after resetting, all words you add to the user dictionary will be deleted.
Hidden Auto Replacement Features in MIUI
Few people know, but MIUI has advanced auto-replacement settings that don't show up in the main menu.
- Open Settings → The phone.
- 5 times tap the MIUI version to turn on the developer mode.
- Return to Settings → Additional settings → Developer settings.
- Find the text input settings and activate Show all keyboard parameters.
After that, additional options will appear in the keyboard settings:
- 🔍 Aggression of auto-replacement (3 levels: low, medium, high).
- 📊 Corrections statistics show which words are most often replaced.
- 🔄 Import/export dictionary – useful when flashing or changing devices.
On Xiaomi 13 Ultra and other flagships, there is another hidden feature called contextual auto-replacement, which analyzes the subject of correspondence and adjusts sentences, and to enable it, you need to activate Adaptive Input in the keyboard settings (defaulted due to increased battery consumption).
💡
Developer mode gives you access to hidden auto-replace settings, but be careful – incorrect changes can lead to keyboard failures.
Alternative Keyboards: Should I Change?
If you don't like the standard MIUI auto-replacement, you can install a third-party keyboard.
- 📱 Gboard (Google) – the best alternative with flexible auto-replacement settings and gesture support.
- ⚡ SwiftKey (Microsoft) – Learns your writing style and offers accurate predictions.
- 🔒 Flesky – Minimalist keyboard with advanced auto-replacement settings.
To change the keyboard:
- Install the selected keyboard from Google Play.
- Go to Settings → Language and Enter → Current Keyboard.
- Activate the new keyboard and follow the setup instructions.
Advantages of third-party keyboards:
- 🌍 Support for multiple languages at the same time (as opposed to the MIUI, switch-over).
- 📤 Synchronizing the user dictionary through the account Google/Microsoft.
- 🎨 More topics and options for design.
Disadvantages:
- ⚠️ Some functions (e.g. gestures in the MIUI) They may not work properly.
- 🔋 Increased battery consumption due to background synchronization.
On the POCO F4 GT and other Xiaomi gaming smartphones, third-party keyboards can conflict with Game Turbo mode. In this case, it is recommended to use the standard MIUI Keyboard or disable Game Turbo for specific applications.
