Xiaomi’s FaceMoji Keyboard has become a popular tool thanks to integrated animated stickers, gifs, and personalized emojis, but over time, users face typical problems: the app slows down, takes up too much memory, or completely stops displaying content correctly, most often due to overloaded cache, accumulated temporary files, or conflicting settings.
In this article, we will look at all the ways to clean the FaceMoji Keyboard on Xiaomi, Redmi and POCO smartphones, from basic cache removal to radical reset to factory settings. We will focus on the nuances that arise on different versions of MIUI (from MIUI 12 to MIUI 14), and also consider alternative methods for devices with limited rights (for example, without root access).
Why does FaceMoji Keyboard need cleaning?
Before you start taking action, it’s important to understand what’s stopping the keyboard from working, and here are the main reasons why FaceMoji may need to clean up:
- 📦 Cache: Temporary files (images, gifs, text prediction data) take up gigabytes of memory, slowing down the work.
- 🔄 Update conflict: after update MIUI or the application itself, old data may interfere with the new version.
- 🎨 Too many loaded stickers: Custom packs (especially animated ones) are stored in the device’s memory.
- 🐞 Sync Errors: If the keyboard is tied to your Mi Account, cloud crashes can duplicate data.
- 📱 System constraints: on budget models (e.g. Redmi) 9A or POCO M3) Lack of RAM exacerbates the problem.
Interestingly, according to Xiaomi Community, up to 30 percent of keyboard support calls are solved by simply cleaning the cache, and many users don’t look at the app’s settings for years, believing it “should be,” while even 500MB of junk files can reduce the speed of text input by 15-20 percent.
Method 1: Clearing the cache through Android settings
The easiest and safest method is to delete temporary files via the standard MIUI menu, which does not affect personal data (saved stickers, input history) and is suitable for all models, including the Xiaomi 13 Pro, Redmi Note 12 and POCO F5.
Instructions:
- Open Settings → Applications → Application Management.
- In the search bar, type FaceMoji Keyboard (or scroll through the list to the Keyboard section).
- Slip on the app, then select Warehouse.
- Click Clear Cache (not to be confused with Clear Data!).
- Confirm action. The system can request permission to stop the application — agree.
After cleaning, restart your smartphone. If the keyboard continues to brake, move on to the next method.
Close all active chats (Telegram, WhatsApp, etc.)
Connect your smartphone to charging (in case of prolonged processing)
Backup important stickers (if any)
Check the space in your memory (should be free) ≥1GB)-->
Method 2: Completely reset the keyboard settings
If cleaning the cache doesn't work, the next step is to reset all of the FaceMoji Keyboard settings to factory settings.
- 🎯 Custom stickers (including downloaded packs).
- ⚙️ Personal settings (key size, themes, languages).
- 📝 Input history (text predictions, frequently used phrases).
Importantly, this method doesn't delete the keyboard system files, so you don't have to reinstall it, but all customizations will disappear.
How to reset your settings:
- Go to Settings → System → Language and input.
- Select the Current Keyboard → FaceMoji Keyboard.
- Put three points on it (⋮) in the upper right corner and select Resetting Settings.
- Confirm the action. The application will restart automatically.

Method 3: Delete application data (radical method)
If the previous methods didn’t work, it’s a complete data cleanup, which will return the FaceMoji Keyboard to the post-installation state, but will require reconfiguration:
- 🔑 All saved passwords (if autocomplete was used).
- 📌 Selected stickers and gifs.
- 🌐 Language Packages (I will have to download again).
Warning: On some devices (e.g. Xiaomi Mi 11 Ultra), after this procedure, the keyboard may temporarily disappear from the list of available ones, in which case it should be re-activated in Settings → Language and input.
Step-by-step:
- Open Settings → Applications → Application Management → FaceMoji Keyboard.
- Select Warehouse. → Clear the data.
- Confirm the action (the system will warn you of data loss).
- Reset the device.
💡
Before you clean it completely, export your favorite stickers! Open the keyboard in any chat room, tap the sticker icon → My Stickers → Select the pack → Export. Files will be saved to the Download/FaceMoji folder.
Method 4: Cleaning through Safe Mode (if the keyboard is not responding)
In rare cases, FaceMoji Keyboard can become so “hangy” that it can not be opened even to reset settings, which will help Safe Mode, a diagnostic mode in which all third-party applications are disabled.
How to run Safe Mode on Xiaomi:
- Press the power button before the turn off menu appears.
- Press the Turn Off (or Reboot) icon before a request to switch to Safe Mode appears.
- Confirm the action. The phone will reboot.
In Safe Mode:
- 🛠️ Remove updates to FaceMoji Keyboard (if any).
- 🗑️ Clear cache and data (as in Method 3).
- 🔄 Restart your phone in normal mode.
⚠️ Warning: Safe Mode disables all keyboards except the standard keyboard AOSP If FaceMoji doesn’t appear on the list after you quit, install it again through the Play Market.
Method 5: Reinstall FaceMoji Keyboard
If none of the methods worked, the application is reinstalled completely, which is useful for devices where FaceMoji is installed as system software (for example, on the Xiaomi Mi 10T or Redmi K40).
Important: on some firmware (MIUI China), the keyboard is part of the system files and cannot be deleted in the standard way.
- Download the latest version of FaceMoji Keyboard from the official Xiaomi website (Support section).
- Install APK-Manually allowing installation from unknown sources (Settings) → Annexes → Special rights → Installation of unknown applications).
- After installation, clean the cache and data (see Method 3).
For devices with unlocked bootloader and root rights, you can use ADB to completely remove the system application:
adb shell pm uninstall --user 0 com.miui.facemoji.keyboard⚠️ Note: Removing system applications through ADB It can lead to unstable work MIUI. Use this method only if you are confident in your actions and are ready for possible consequences (for example, resetting to factory settings).
Additional Optimization Tips
To make FaceMoji Keyboard work consistently, follow these guidelines:
| Problem. | Decision | For which devices |
|---|---|---|
| The keyboard brakes when entering | Turn off sticker animation in keyboard settings | All models. |
| No new stickers loaded | Check your internet connection and clear the cache | Redmi Note 11, POCO X4 and newer |
| Too much traffic expense | Turn off automatic sticker download in Settings → FaceMoji → Data | Devices with MIUI 12.5+ |
| The keyboard spontaneously changes the language | Remove unnecessary language packs in keyboard settings | All models. |
If you are actively using stickers, clean FaceMoji cache regularly (every 1-2 months) through Settings → Storage. Also, limit the number of packs simultaneously downloaded - it is optimal to keep no more than 5-7 active sets.
💡
Regularly cleaning the cache and removing unnecessary stickers can increase keyboard speed by 30-40%.
