Xiaomi smartphone users often face a situation where a third-party keyboard starts to work incorrectly, offer inappropriate words or simply take up too much space. Facemoji Keyboard is a popular application that adds a lot of emojis and stickers, but over time its database grows. Accumulated software debris can cause interface lags and predictive input errors.
In this article, we will take a look at how to clean up your data and cached files completely, how to safely delete temporary files without losing important settings if you don’t need to, and how to understand the storage structure in the MIUI or HyperOS shell will help you keep your device in optimal condition.
Sometimes, standard removal of an application doesn't solve the problem completely, as residual files can be saved to system folders. A full reset of application data through Android settings is a more effective method than simply reinstalling from the Play Market Store. We'll look at all the available methods, including deep analysis of the space occupied.
Why you should clean the keyboard periodically
Over time, predictive typing algorithms learn from your habits, saving thousands of words and phrases. This creates a voluminous dictionary file that can be corrupted or conflicted with system updates. If you notice that the keyboard is late typing or offering odd word variants, that's a sure sign to intervene.
Facemoji also uses graphics to display themes and animations. Image cache can take hundreds of megabytes, which is critical for devices with little internal memory. Regular cleaning frees up space and speeds up system response.
It's important to understand the difference between cache and user data. Cache is temporary files that can be deleted safely, and data includes your dictionaries, your input history, and personalized theme settings.

- 💾 Freeing Internal Memory from Graphic Garbage
- 🔒 Removing confidential input history before selling your phone
- 🛠 Correction of synchronization errors and application failures
⚠️ Warning: Cleaning up the data will reset all keyboard settings to factory ones, and you will lose learned words and saved themes if they are not synced to the cloud.
Basic cleaning through Android settings
The easiest and safest way to remove the accumulated debris is to use the built-in operating system tools. This method does not require installing additional software and is available on any Xiaomi smartphone.
Go to Settings for your device. Find the App, then select All Apps. In the installed program list, look for Facemoji Keyboard. If there are many programs on the list, search by name.
Once you open the app card, you will see the Clean (or broom icon) button at the bottom of the screen, clicking on it will open submenu with a choice of cleaning type. To completely reset, select Clear Everything, and to delete only temporary files, Clear Cache.
☑️ Basic cleaning algorithm
Once these steps are done, the system will force the keyboard process to close, and the next time Facemoji is activated, it will start as the first one installed, requesting basic permissions.
Deep cleaning through MIUI storage
The MIUI shell provides more detailed access to the application file system, which is useful if the standard cleanup button fails or the interface freezes, and you can see the exact distribution of the space you're taking here.
In the Facemoji Keyboard management menu, look for the Warehouse section, and it shows the memory usage schedule, and you'll see the division between the size of the application, the size of the data, and the size of the cache, and you'll make an informed decision about what to delete.
If you want to save your themes but fix work errors, try to clean only the cache. If the problem is in the dictionary or settings, you will need to clean the data. In some versions of the firmware, the option is available to Remove Updates, which will roll back the application to the factory version built into the installation package.
| Type of data | What does it contain? | Safe to remove | Impact on work |
|---|---|---|---|
| Size of the annex | Executable code and resources | No (removal only) | Critical (app will disappear) |
| User data | Dictionary, topics, settings | Yeah (with loss of settings) | Reset to factory settings |
| Cash. | Temporary files, thumbnails | Yes (completely safe) | Acceleration of work, no loss of settings |
| Other | Log files and stuff. | Yes. | Minimum |
💡
Use the Cache Clear feature regularly, such as once a month, to prevent temporary files from sprawling without losing your personalizations.
Use of the Application Security
Xiaomi smartphones pre-installed the system app Security, which can find and remove garbage in installed programs, it is a convenient tool for comprehensive prevention, although it does not always give full control over a particular application.
Run the Security app and select Cleanup. The system scans the device for temporary files. After scanning, scroll down to Apps or App Cache. Search the Facemoji Keyboard list and tick it to delete.
This method is good because it allows you to clear the cache of several programs at once. However, it rarely offers the option of complete data cleanup, as this is considered a potentially dangerous action for the stability of the system.
Note that the cleaning algorithms in MIUI can be aggressive, check periodically to see if your settings have reset after automatic cleaning, and if necessary, reconfigure the keyboard.
Radical measures: removal and re-installation
If the data cleanup didn’t work and Facemoji Keyboard continues to work incorrectly, the only way out is to completely reinstall it, which is guaranteed to remove all corrupted files and replace them with a fresh version from the repository.
To start, remove the app completely. Press the icon on your desktop or menu and select Delete. After that, it is recommended to restart your smartphone so that the system clears the temporary registry entries. Then go to Google Play or GetApps and download the keyboard again.
When you first install it, you will request permission to access the clipboard and microphone (for voice input). Be careful when granting permissions. Once installed, recreate an account or log in to an existing one to restore the themes or settings you bought if you have synced.
⚠️ Note: When you delete the application through a long-term icon click, the data is also deleted.Make sure you remember your password from your Facemoji account to restore progress.
What to do if the application is not removed?
Setting up privacy and resetting the dictionary
The keyboard dictionary stores the history of what you typed, and if you transfer the phone to another person or sell it, cleaning the cache is not enough, you need to delete user data.
Inside the Facemoji app itself, there's often a Settings -> Additional -> Reset, an internal feature that duplicates system cleaning, but it can be more convenient if you're right in the print interface, and you can turn off the use statistics.
For maximum security, before cleaning, it is recommended to turn off the Internet so that the application does not have time to sync local debris with the cloud before removing. After cleaning the data and resetting the settings, the phone will become cleaner and the keyboard will work faster.
💡
Regularly resetting your vocabulary (every 3-6 months) is not only useful for performance, but also for the relevance of predictive input, as your interests may change.
Remember that modern versions of Android strictly control access to the clipboard. When cleaning the keyboard data, the clipboard can also be cleared, so copied text is better stored in notes before the procedure.
