Xiaomi smartphones are famous for their performance, but over time, even the most powerful devices can experience software failures. One of the most annoying things for the user is the malfunction of the virtual keyboard. Characters can be printed with a delay, predictive text stops guessing words, and the input panel itself suddenly disappears or freezes. Often the root of the problem is a crowded or corrupted cache.
Cache is a temporary storage device that the operating system uses to speed up access to frequently used information. In the case of the keyboard, it stores dictionaries, input history, emojis and design settings. When that volume gets too large or files are corrupted, Android becomes unstable. Clearing that data is a safe and effective way to restore the gadget to its usual responsiveness without losing personal messages or contacts.
In this article, we will discuss in detail the process of cleaning the cache on the shell of MIUI and HyperOS. We will look at the standard methods, work with system applications and answer the complex questions that arise from owners of Redmi and Poco. It is important to understand that the procedure does not require root rights and takes only a couple of minutes, but requires careful navigation through the settings menu.
Why you need to clean the keyboard cache on Android
Many users ignore the maintenance of system applications, believing that they work autonomously. However, a virtual keyboard is an active process that constantly analyzes your actions. It remembers the frequency of use of certain words, abbreviations and even specific characters. Over time, the database grows, occupying a significant space and putting a strain on the processor every time you touch the screen.
There are several clear signs that the keyboard temporary storage files are damaged or overcrowded, and if you notice that letters appear on the screen a second after you press, or the keyboard spontaneously closes while you type in the messenger, this is the first bell, and problems can also manifest in the incorrect operation of autocorrection, when simple words are replaced with a meaningless set of letters.
Regular cleaning helps not only fix current bugs, but also prevent future crashes. This is especially true after major MIUI system updates, when old configuration files may conflict with new operating algorithms. Cache resets the app back to factory temporary data storage settings without affecting your personal dictionaries and saved passwords if they are synchronized with the cloud.
Preparing a smartphone before cleaning system data
Before making changes to the system components, you need to make sure that the connection is stable and battery charge is safe. Although the procedure is safe, interruption of the process due to a discharged battery can lead to unpredictable results, it is recommended to connect the device to the network or make sure that the charge level is at least 30-40%.
It's also worth checking which keyboard is the default. On Xiaomi smartphones, it could be Gboard, Sogou, or the standard MIUI Keyboard. The way to setup depends on the type of application. If you use a third-party keyboard downloaded from the Play Market, the path may be slightly different, but the general principle remains the same for the entire Android ecosystem.
It's important to understand the difference between clearing the cache and resetting to factory settings. We'll only delete temporary files, which is safe. However, if you decide to click the "Erase Data" or "Clear All" button, you'll lose saved user dictionaries and personalization. Be careful when selecting buttons in the application management menu.

How to Clear Gboard Keyboard Cache on Xiaomi
Google's Gboard keyboard is the most common on Xiaomi devices sold globally. The cleaning process here is standardized, but has its own nuances depending on the shell version. First, you need to go to the main smartphone settings menu. Find a section that is usually called "Apps" or "All Apps."
In the list of all installed programs, sort them by name or manually find Gboard. Note that some versions of MIUI may have multiple Google-related components, so choose the keyboard icon. Once you log into the app menu, you will see the Storage or Memory button, which is responsible for managing files.
The storage screen will display two main buttons: Clear Cache and Clear All (or Reset) and we need the first option. Clicking Clear Cache will delete temporary files, speeding up the app. Don't confuse this button with the second one, as Clear All will delete your personal dictionaries and settings.
⚠️ Warning: If you accidentally chose Clear Everything, don't panic.The keyboard will just go back to the out-of-the-box state and you'll have to reconfigure the language and theme, but Google's personal account details will remain safe.
Once cleaned, it is recommended that you completely close the keyboard application through the task manager and open it again. This will start the process of creating new temporary files from scratch. Usually, changes take effect instantly, and the printing delays disappear. If the problem persisted due to a crowded cache, now it must be resolved.
Delete temporary files of the standard MIUI keyboard
Devices designed for the Chinese market or some CIS regions have a keyboard installed by default from Xiaomi, which is deeply integrated into the shell, so you can find its settings not only through the general application menu, but also through specific paths, often hidden under the name "Keyboard Application" or miuiinput in the list of system processes.
To access memory management, open Settings → Advanced Settings → Language and input. Here, select the active input method. The window that opens often has a direct link to app information. If there is no such link, use a global search by settings by entering the word “keyboard”.
The procedure is similar to Gboard, where you go to storage and you pick to clear the cache. The MIUI Keyboard is that it can accumulate a lot of data about the themes and stickers that are also stored in the cache, and removing them frees up space and can eliminate visual bugs like missing buttons or incorrect display of skins.
Specifics of cleaning on different versions of MIUI and HyperOS
Xiaomi’s shell interface is constantly changing, and the paths to settings may vary depending on the version of MIUI or the new HyperOS. In older versions (MIUI 10-12), the menu was flatter, and you could find the application faster. In new versions (MIUI 13-14, HyperOS), the structure became deeper and more logical, but the names of items could change.
Below is a table that will help you navigate the menu differences for different versions of the firmware, which will make it easier to find the right item, even if the names are slightly different from the ones described above.
| Shell version | The path to applications | Name of the cleaning point | Features |
|---|---|---|---|
| MIUI 11-12 | Settings → Applications | Memory. → Clear the cache | Classical interface |
| MIUI 13-14 | Settings → Applications → All applications | Warehouse → Clear the cache | Added search by appendix |
| HyperOS 1.0 | Settings → Applications → All applications | Memory. → Clear the cache | Optimized menu animation |
| Global ROM | Settings → System → Applications | Use of memory → Clean up | The structure may differ |
HyperOS owners should look to the new memory management system, where cache cleaning can be done more aggressively by self-service, but manual control is still the most reliable way to solve specific typing problems. If you've recently upgraded and encountered lags, cleaning the cache is the first thing to do.
Solving problems if the cache is not cleared
Sometimes users are faced with a situation where the Clear Cache button is inactive (gray) or after cleaning the problem returns after a few minutes.This may indicate deeper system errors or access rights conflicts.In such cases, simple cleaning of temporary files may not help, and a more radical approach will be required.
The first step if you fail is to reboot your device to Safe Mode, which will disable any third-party applications that may block your system keyboard or create your own cache over your system keyboard, and if you have a safe keyboard that works normally, then some application you have installed is in conflict.
If the problem persists even after rebooting and cleaning attempts, you can try to remove updates to the keyboard application itself. To do this, in the app menu (the same as cleaning the cache), click on the three dots in the top corner and select "Delete Updates." This will return the keyboard to the factory version built into the firmware, which often solves problems that arose after a failed update.
⚠️ Note: Removing keyboard updates may temporarily change the look of the keyboard or remove new features, but this is guaranteed to eliminate errors caused by corrupting updated files.
Preventing keyboard failures on Xiaomi
To avoid going back to cleaning the cache too often, there are a few simple rules to use: first of all, don't install questionable themes and fonts from unreliable sources. Unofficial keyboard modifications often contain code errors that lead to memory leaks and fast cache overflows.
Regularly update system components through the GetApps or Play Market app. Developers are constantly releasing patches that fix optimization bugs. It is also useful to reboot your smartphone at least once a month so that the system can independently maintain background processes and clear temporary files.
Keep an eye on the storage space in your device. If your internal storage is more than 90% full, you can't create new temporary files, causing all applications to crash, including the keyboard. Keeping at least 2-3 GB of free space is key to Android's stable operation.
