Many Xiaomi, Redmi and POCO smartphone users are faced with a situation where copied text or image stop being pasted, or there is a desire to erase sensitive data temporarily stored in the device’s memory. The clipboard is a hidden area of RAM that stores information until you copy something new or reboot the gadget. Unlike files in the gallery, this temporary archive has no obvious interface to manage.
On Android, including the branded MIUI shells and the new HyperOS, the cleanup process isn’t always obvious to the beginner. The standard settings menu doesn’t explicitly include the Clear Buffer button, as the system is designed to automatically replace old data with new ones.
In this guide, we will cover all the current methods, from simple keyboard actions to the use of system tools for advanced users. On Xiaomi devices with HyperOS shell, the buffer mechanism has been reworked, which requires special attention to software versions. You will learn to safely delete copy history without affecting important phone files.
What is a clipboard and why you need to clean it
Clipboard is a temporary storage in RAM, where any information after the command "Copy" or "Slice" gets into it. This can be text from a message, a link to a site, a screenshot or even a file. The data is there until you copy something else or turn off the device, because when you lose power, the content of the RAM is erased.
The need to clean up arises for various reasons: sometimes users accidentally copy sensitive data, such as passwords, SMS codes or bank card numbers, and do not want this information to remain available to applications that have access to the buffer, and cleaning helps if the system starts to work unstable or the keyboard freezes when you try to insert.
⚠️ Note: The Android clipboard does not have its own file storage in the phone’s memory that can be found and cleared through Explorer. All operations are performed either through the keyboard interface or by restarting system processes.
It’s worth noting that on modern versions of MIUI and HyperOS, the buffer is often integrated into the keyboard, so managing your copy history depends on whether the default virtual keyboard is the standard Gboard or MIUI Keyboard.
Cleaning the buffer through the standard Gboard keyboard
Most of Xiaomi’s global smartphone versions pre-installed Google’s Gboard keyboard, which has a built-in clipboard manager that stores the history of recent copied items, a handy tool, but it requires periodic cleaning to protect privacy.
To access the story, open any app where you can type in text, such as Notes or Telegram. Click on the input field to call the keyboard. In the top toolbar, find an icon resembling a notebook or buffer. If there is no icon, click on the arrow or four dots on the left to open the additional menu, and select "Chapter Buffer."
In the window that opens, you will see a list of all the saved items. To clean one item, click on it and hold your finger, then select the basket icon. To delete everything at once, look for the "Clean All" or "Delete All" button (usually located in the top corner or in the three-dot menu).
- 📋 Click on the clipboard icon in the Gboard toolbar to access the story.
- 🗑️ Hold your finger on the item to activate select and delete mode.
- 🧹 Use the Clean All feature to instantly delete your entire copy history.
It's important to understand that cleaning through Gboard only removes the history stored in the keyboard application. The current active element that you can insert right now will also be deleted. After this procedure, no data will remain in the buffer.

Buffer management in MIUI Keyboard and HyperOS
Owners of smartphones bought in China or users who have migrated the device to Chinese firmware often use the MIUI Keyboard. In new updates, especially in HyperOS, the clipboard functionality has been expanded to become more visually visible.
To enter the menu, click on the buffer icon at the top of the keyboard. If you use HyperOS, the system may suggest saving copied data to the cloud or syncing it with other devices in the Xiaomi ecosystem, which creates additional copies of data that you need to remember.
To clear the data, go to the buffer settings (usually a gear or three dots), where you can find the option "Clear history" or "Delete all records", and MIUI has a function to automatically clean the buffer after a certain time, which is recommended to activate for security purposes.
| Function | Gboard (Google) | MIUI Keyboard / HyperOS | Third-party keyboards |
|---|---|---|---|
| Storage of history | Locally in the appendix | Local + Cloud Xiaomi | Depends on the developer. |
| Fixing of elements | There is. | There is. | Often |
| Auto-cleaning | No (only by hand) | Customizable timer | Miscellaneous implementation |
| Synchronization | Through a Google account | Through the Mi Cloud | Rarely. |
HyperOS users should pay attention to privacy settings, the system can warn that the application is trying to read the clipboard, and regular cleaning reduces the risk of data leakage through these requests.
Why does the buffer reset after rebooting?
Using a task manager to reset memory
If you don’t have access to your keyboard history or want to guarantee that you erase the active buffer (the last copy), the most effective way is to force the process of typing to stop. On Xiaomi smartphones, the system app or the keyboard itself is often responsible for this.
Go to your smartphone settings, find the Apps section, and select All Apps. From the list, find your keyboard (like Gboard or MIUI Keyboard) or the Clipboard app (if it's highlighted as a separate process in your version of MIUI). Click on it and select Stop or Close.
When the process stops the next time you run the keyboard, the buffer will be empty, which works because the application is initialized again, and the temporary data is not downloaded from the storage unless synchronization has been enabled.
- 🔍 Go to Settings. → Annexes → All applications.
- 📱 Find your main keyboard in the list.
- 🛑 Click the “Stop” or “Close” button».
- ✅ The next time the keyboard is turned on, the buffer will be cleared.
This method is especially useful if the keyboard is not working properly or is “glutching” when inserting text. Forced rebooting of the process often solves minor software failures.
💡
Before you stop system processes, make sure you don’t need to copy important text right now, as it will be lost without the possibility of recovery.
Radical method: Rebooting the smartphone
The easiest and most reliable way to completely clear the clipboard on any Xiaomi, Redmi or POCO phone is to simply reboot the device.As mentioned earlier, the resides clipboard in RAM, which is cleared when the power is turned off.
You don't have to look for special buttons or menus. Just press and hold the power button, select "Switch off" or "Reboot." Once you turn on the phone, the clipboard is guaranteed to be empty, with no text, no images, no links left.
This method is also recommended if the phone has started to run slowly.RAM cleaning when rebooting frees up system resources, deletes temporary files and resets suspended processes, which has a positive effect on performance.
⚠️ Warning: Rebooting is the only way to clear the buffer 100% if you’ve used multiple different keyboards or apps that could save data in their cache independently of each other.
Don't be afraid to reboot your smartphone often. For Android, it's a routine maintenance procedure, and it's recommended to do this at least once a week to keep MIUI or HyperOS running smoothly.
Third-party buffer management applications
If standard tools aren't enough, there are many clipboard management apps on Google Play that provide advanced functionality: note-taking, cloud sync, text formatting, and of course deep cleaning.
Popular apps like Clipboard Manager or Clipper can intercept anything you copy and save it to your database. These apps have handy "Clean All," "Clean Old Records" buttons, and settings for automatic data deletion after a given period of time.
But be careful: When you install a third-party manager, you give them access to all the information you copy, which can be passwords, personal correspondence, financial information, and only use proven applications with high ratings and good reviews.
- 📥 Download a reliable buffer manager from Google Play.
- 🔐 Provide the necessary permissions to access the buffer.
- ⚙️ Set up an automatic history cleanup in 1 hour or 1 day.
- 🧹 Use the built-in application tools for mass deletion.
For most users, standard Gboard and MIUI features are sufficient, and third-party applications are needed mainly by those who work with large volumes of text and need an extended copy history.
