Using a Xiaomi Redmi smartphone every day involves typing vast amounts of text, from instant messaging to passwords and search queries. Over time, the virtual keyboard becomes rife with digital junk that can slow down your device or, more importantly, compromise your privacy. Cleaning your keyboard isn’t just about removing unnecessary words, it’s a necessary procedure to optimize your system and protect your personal data.
Owners of MIUI or HyperOS devices often find themselves in a situation where autocorrecting starts to behave strangely, offering forgotten words or incorrect replacements. This is due to a crowded dictionary and accumulated cache. In this article, we will discuss in detail all the ways of cleaning, from simply deleting history to completely resetting the input application settings.
Before you start taking drastic measures, it’s important to understand what exactly you want to clean up, whether it’s an app’s temporary memory, word typing history, or personalized settings. A full keyboard reset will remove all learned words and gestures, returning it to the “out of the box” state, so follow the instructions carefully so you don’t lose important autocomplete data.
Why you need to clean the keyboard on your smartphone
The main reason for regular cleaning is data security, and the keyboard remembers everything you type to suggest the most likely word variants, but it can also get passwords, card numbers, addresses, and other sensitive information that is best not stored in the dictionary of the device.
The second aspect is performance: When the word database gets too big, the application needs more CPU resources to process input and predict text. On Redmi's budget models, it can feel like a slight delay when letters appear on the screen. Regular cleaning helps keep the system running at a high level.
And it's also worth mentioning autocorrect error correction, which is that if a keyboard starts obsessively changing the right words to strange ones, it's got a bug or a learning problem, and resetting it eliminates this digital noise and restores the accuracy of the input.

- ⚡ Accelerating interface response when typing.
- 🔧 Correction of Autocorrection and Prediction Errors.
- 🗑️ Freeing internal storage from temporary files.
Clearing History and Cache Through System Settings
The easiest and safest way to get your keyboard in order is to use the built-in Android operating system.This method doesn’t remove your personal dictionaries completely, but clears temporary files and usage history, which often solves the problems with the app freeze.
To start, you need to go to the settings menu of your Xiaomi Redmi.Look for the section responsible for managing installed applications.The path may vary slightly depending on the version of MIUI, but the logic remains the same for all devices of the brand.
In the app list, find your main keyboard, most commonly Google's Gboard or the standard MIUI Keyboard, and clicking on it will take you to the control menu, where we're interested in items related to the device's memory.
⚠️ Warning: Cache cleaning is safe and won't delete your personal settings, but the "Erase Data" or "Clean Everything" button will completely reset the app to factory state by removing learned words and selected topics.
Once you have selected an action, the system may request confirmation, and if you have chosen to clear the data, the keyboard will restart and you will need to re-allow the microphone (for voice input) and contacts if necessary.
☑️ Algorithm of actions in settings
Delete word history in Gboard and MIUI Keyboard
If your goal is to remove specific words from prompts or clear your search history without resetting all your design settings, use the internal menu of the keyboard itself, a more point-based method that allows you to keep the appearance of the buttons familiar.
In the Gboard keyboard, which is the default on most global versions of Redmi, history management is in the settings section of the app itself. Open any type field to call the keyboard, and find the gear icon or menu icon.
In the settings menu, select “Additional” or “Privacy” where you will find the option “Clear Use History” and clicking this button will remove the list of words that the keyboard has memorized from your input, but will save the dictionaries you have added manually.
For owners of MIUI shell devices (Chinese version or old globals), the process looks similar. In the keyboard settings, you need to find the "Dictionary" or "Text" section, where you can reset learned words, which is useful if you change the language of communication or just want to start with a clean slate.
| Function | Gboard (Google) | MIUI Keyboard | SwiftKey |
|---|---|---|---|
| The path to cleanup | Settings → Additional | Settings → Dictionary | Settings → Printing |
| Deletion of history | Clear the history of use | Clear the learned words | Clearing the training data |
| Keeping topics | Yes. | Yes. | Yes. |
| Dictionary reset | Separate button | General menu | In the Account section |

Reset keyboard settings to factory
In situations where the keyboard is not working properly, it is buggy, or you just want to update its functionality completely, a complete reset is required, which will return the input application to the state in which it was immediately after installing the operating system.
This can be done through the application menu, as described earlier by selecting Clear All Data, but there is an alternative way to adjust the keyboard itself, which may be more convenient for some users.
Open your keyboard settings, go to System or General Settings, and at the bottom of the list, you usually find either Reset or Restore by Default, and the system will alert you that all personalizations will be lost.
Once you reset the first keyboard call, you will be asked to choose the language, layout and allow access to the necessary features again, a great way to get rid of software errors that have arisen after the Xiaomi firmware update.
💡
Before resetting your keyboard completely, take screenshots of your current settings if you have been adjusting button height, pressing sounds, or vibration for a long time to quickly restore comfortable settings.
Removal of individual words from the dictionary
It's often the case that there's one particular word left in the dictionary that's annoying because it's always coming up in the prompts, and it could be a typo you once made, or a slang expression that's no longer relevant, and you don't have to delete the entire dictionary because of that.
Modern versions of the Gboard and MIUI Keyboard have a quick delete feature, so when you type text and an unnecessary word appears in the hintbar (above the keyboard), try pinching it with your finger for a second or two.
A pop-up will appear asking, "Should I remove this word from the dictionary?" or "No more offer." Confirm the action, and the keyboard will stop associating the letters you typed with this option. This works for both individual words and short phrases.
If the delay is not working, you can use the Personal Dictionary menu in the keyboard settings, which stores a list of all the words you have added manually or that the system has deemed important, find an unnecessary word in the list and delete it by clicking on the basket icon or minus.
- 📱 Click on the unnecessary word in the prediction bar for quick removal.
- 📝 Use a personal dictionary to manage hand-added words.
- 🔄 Synchronizing a dictionary can return a deleted word if you don’t turn it off.
Third-party keyboards and their cleaning
Xiaomi Redmi users often install alternative keyboards, such as Yandex Keyboard, SwiftKey or Typewise, which are similar to the system keyboard, but the paths to settings may differ, usually inside the keyboard application itself, under Profile or Settings.
For example, in SwiftKey, all data is stored in a cloud profile or locally, and to clean up, you need to go to the Privacy and Data section, where you can clear the cache, history, and even delete the account, which will lead to a complete reset of prediction settings.
When cleaning them, make sure you delete the application’s data, not the system files, and after cleaning the third-party keyboard, you may need to re-activate it in the Language and Input menu.
⚠️ Warning: When installing third-party keyboards from unknown sources, always check the permissions requested. Some applications may request access to the clipboard or contacts without a real need to work.
If the third-party keyboard stopped working correctly after cleaning, try removing it completely through the app menu, restarting the phone and installing it again, and this is guaranteed to delete any residual configuration files.
💡
Third-party keyboards often have their own cloud backups, so simply clearing the cache on the phone may not delete data synced to the developer account.
