How to Remove Words from T9 in Xiaomi: A Complete Cleanup Guide

Xiaomi’s modern smartphones are equipped with intelligent input systems that eventually irritate users with intrusive cues. The algorithm-accumulated dictionary often contains typos, slang, or simply misrecognized phrases that the system persistently suggests when typing, which not only distracts but also slows down the communication process, causing them to constantly reject inappropriate options.

Cleaning up the T9 dictionary is a necessary procedure for those who want to return the original accuracy of the prediction to the keyboard. In a MIUI or HyperOS operating system, this process may not be obvious, since the settings are scattered across different menus, but there are proven ways to completely erase the accumulated data and start with a clean slate.

In this article, we will discuss detailed instructions for removing unwanted words and completely resetting keyboard settings. You will learn how to work with the system dictionary, how to manage personal data in Gboard, and what hidden opportunities exist for advanced users.

Anatomy of the keyboard dictionary on Xiaomi

Before you start deleting, it's important to understand where exactly the data you're typing is stored. Xiaomi smartphones use a complex input caching system that is divided into several layers. The first layer is a temporary buffer where words from the current typing session fall, and these data are quickly forgotten by the system after rebooting or changing context.

The second layer is the personal vocabulary, which is stored in the device's memory all the time, and it's where your familiar abbreviations, contact names, and commonly used but non-standard words live, and the third layer is cloud data if you're syncing with your Google or Xiaomi Cloud account, and deleting words at one level doesn't always clear others, which often causes confusion among users.

Many people mistakenly believe that it is enough to simply remove the prompt by swipe to disappear forever. In fact, this action only temporarily hides the word from the priority list, but does not remove it from the database. To ensure the result, you need to directly influence the settings files or use special reset commands, which we will discuss below.

• 📱 Local Storage: Located inside the keyboard application memory and not synced to the cloud without your knowledge.
• ☁️ Cloud Profile: Contains aggregated data about your print style collected by the corporation to improve algorithms.
• ⚙️ Systems dictionary: A basic set of language words that cannot be deleted but can be adjusted with custom add-ons.

Delete individual words through the Gboard interface

The most common keyboard on Xiaomi smartphones is Google’s Gboard, which has a convenient but not always obvious mechanism for managing a personal dictionary. To remove a specific word that pops up in prompts, you need to go to the settings of the app itself. Open the smartphone settings menu and find the option to Settings, then select Language and Type.

In the menu that opens, select Gboard and go to the Dictionary section, which displays a list of all the words you have ever added manually or that the system has memorized as a priority. Find an unnecessary word in the list and click on the basket icon next to it. This action will instantly delete the entry from the keyboard database.

If a word is not in the dictionary's explicit list but keeps appearing, try a long tap on the prompt itself on the keyboard bar. In some versions of MIUI firmware, this causes a context menu asking "Delete?" A confirmation of action will remove the word from the current ranking, although the algorithm may try to return it after a while of active use.

💡

Use the “Block Unwanted Words” feature in Gboard settings to automatically hide the obscene vocabulary and slang from the prompts.

It's worth noting that manual deletion is only effective for a small number of records, and if you want to clear the history completely, it will take too long, and then you'd better use the more radical but effective measures to clean up the cache and application data, which will be discussed in the next sections.

Complete reset of keyboard settings

The radical but most effective way to get rid of all the accumulated errors and incorrect words is to completely reset the keyboard settings. This process returns the input application to the “out of the box” state, removing all the accumulated experience, user habits and, of course, the entire T9 dictionary. Before starting the procedure, make sure you remember your passwords, as autocomplete will also be reset.

To do the cleaning, go to Settings → Apps → All Apps. Find your keyboard (most commonly Gboard or MIUI Keyboard) in the list. Log in the app menu and select Memory. Here you are interested in two buttons: Clear Cache and Clear All (or Reset) and click on the second option and confirm the action in the window that appears.

After this procedure, the keyboard will forget all the unique words, nicknames, addresses and specific terms you previously entered. The first time you type, the system will start learning your handwriting and communication style again, which can take anywhere from a few hours to a couple of days of active use, but the result will be clean and unbiased.

⚠️ Warning: A full keyboard reset will also remove saved custom dictionaries and theme settings. If you used custom themes or specific layouts, they will have to be reconfigured.

Managing Google’s Personal Dictionary

Because most Xiaomi users use the Google ecosystem, a significant portion of your print style data is stored in your account, managed via a web interface or customizations inside your smartphone, which allows you to synchronize the vocabulary between devices, but also means that deleting a word on your phone may require checking your cloud profile.

To access dictionary management, open Gboard settings and search the Additional or Personal Dictionary section, and you can see a list of words associated with your account. Deleting entries from here ensures that they won't come back after reinstalling apps or changing devices, especially for those who often change gadgets or use a tablet and phone in parallel.

There is also the option of exporting and importing a dictionary, which is useful if you want to migrate your settings to a new phone or save a backup before experimenting. Dictionary files usually have a.txt extension or a specific database format that is read only by system input utilities.

Using ADB for deep cleaning

For advanced users who are not afraid of the command line, there is a way to clear the dictionary through the ADB debugging bridge (Android Debug Bridge), which allows you to delete database files directly, bypassing standard interface restrictions, and is especially useful in cases where a standard reset does not help or the keyboard behaves incorrectly due to damage to the dictionary files.

To start, you need to turn on the developer mode on your Xiaomi. Go to About Phone and quickly click on the MIUI build number seven times. Then in advanced settings, activate Debugging over USB. Connect the phone to your computer and launch the terminal with the ADB installed. Enter a command to access the shell of the device.

adb shell pm clear com.google.android.inputmethod.latin

This command completely cleans the Gboard app data. If you use a standard MIUI keyboard, the package will be called differently, usually com.android.inputmethod.miui. Executing a command is equivalent to deleting the application and installing it again, but it takes a couple of seconds. All dictionaries, clipboard history and settings will be irretrievably lost.

Prevention and alternative solutions

To keep the problem of the clogged T9 dictionary from returning, it is recommended to periodically conduct preventive cleaning. Do not allow thousands of erroneous entries to accumulate. If you notice that the keyboard has begun to make mistakes, it is better to remove the wrong word immediately than wait until it is fixed in priority. Regular maintenance of the input system prolongs the comfort of using the smartphone.

Alternatively, third-party keyboards like SwiftKey or Yandex Keyboard can be installed, with their own, often smarter prediction algorithms that allow you to flexibly manage your vocabulary. SwiftKey, for example, has a Trends feature that allows you to quickly delete words typed in certain applications without affecting the general vocabulary.

You should also pay attention to autocorrect settings. Sometimes the problem is not with the dictionary itself, but with too aggressive correction. Decreased autocorrect sensitivity in Settings → Text → Autocorrection can reduce the number of intrusive and incorrect substitutions, making communication more natural.

⚠️ Note: When installing third-party keyboards from unverified sources, there is a risk of leakage of input data (passwords, cards.

💡

Regularly cleaning the keyboard cache every 3-4 months helps maintain high accuracy of word prediction and prevents the accumulation of system debris.
