The clipboard on Xiaomi Redmi 7 is a temporary storage for text, links and images that you copy while working with your smartphone. Over time, it fills up with unnecessary data, which can slow down the device or even pose a threat to privacy. This is especially true for owners of Redmi 7, where the amount of RAM is limited to 2-4 GB, and the MIUI firmware actively caches the copied information.
Unlike iOS or pure Android, where the clipboard clears automatically after rebooting, on Xiaomi it can store data for weeks, which is due to the features of the MIUI shell, which integrates the clipboard with system services, for example, if you copied a password or bank card number, this data will remain available for any applications with buffer rights - until you manually delete it.
In this article, we will discuss all the ways to clean up the clipboard on Redmi 7, including hidden MIUI 10/11/12 features that are not documented in the official certificate, learn how to delete data selectively or completely, and how to disable the clipboard history to prevent leakage of confidential information.
Why Xiaomi Redmi 7 should be cleaned regularly
Many users underestimate the risks associated with a crowded clipboard. On Redmi 7, this feature works differently than on Android stock:
- ๐ฑ Slowing down the system: MIUI It stores copies of text and images in RAM. If you actively use the copy-paste function, the buffer can take up to 100-200 MB of RAM, which is critical for a budget smartphone.
- ๐ Security Threat: Apps with Permits ACCESS_CLIPBOARD (For example, some keyboards or file managers can read the history of the buffer without you knowing it, even if it's deleted, before it's completely overwritten.
- ๐๏ธ Artifacts after removal: B MIUI The clipboard is not completely cleared when rebooted.Residual data can be restored through system logs or backups.
- ๐ Application conflicts: Some programs (e.g. Google Keep or Evernote) automatically save the contents of the buffer, creating duplicate notes.
On Xiaomi Redmi 7, the clipboard is integrated with the Mi Cloud service: if synchronization is enabled, the copied data can automatically be downloaded to Xiaomi remote servers, even if you are not actively using the cloud. This means that clearing the buffer on the device does not guarantee the removal of data from the companyโs servers. To completely eliminate leakage, you need to disable synchronization in the Mi Account settings.
โ ๏ธ Note: If you use Redmi 7 to handle financial data (e.g., copying details for transfers), clear the clipboard immediately after surgery. In 2022, security researchers discovered a vulnerability in the security system. MIUI, This allows attackers to recover text from the buffer even after it is โcleanedโ through a standard menu.
Method 1: Standard cleaning through the notification panel
The easiest method is to use the built-in MIUI function to manage the clipboard, which is available on all firmware versions for Redmi 7 (from MIUI 10 to MIUI 12.5):
- Copy any text (e.g., the symbol "a") โ this will activate the clipboard.
- Slip on the notification Text copied in the top curtain.
- In the window that opens, press three points (โฎ) top-right.
- Choose Clear All or delete individual records by swiping them to the left.
This method only removes text data. Images and files copied through the Share menu will remain in the buffer, and the method does not work if the notification panel is disabled for system applications (check in Settings โ Notifications โ System applications).

โ ๏ธ Note: If the clipboard shows old data again after cleaning, this is a sign of a malfunction of the com.miui.clipboard service. In this case, only a full reboot of the smartphone or a reset of settings will help (see Method 5).
Method 2: Clean up via MIUI settings (hidden section)
MIUI 11 and later has a hidden clipboard management section that doesn't show up in the main settings menu.
- Go to Settings. โ Additionally.
- Slip on the line Special Opportunities.
- Scroll down and select the clipboard (on some versions - Text Management).
- Click Clear History or turn off the option Save Clipboard History.
This method removes all history, including images and files, but does not affect data synchronized with Mi Cloud. If the clipboard partition is not in your firmware, then it is blocked by the manufacturer for your region.

Method 3: Using a file manager for manual cleaning
If standard methods don't work, you can manually delete clipboard files through system folders, which requires root rights or developer mode activation:
- Open the file manager (standard or Root Explorer).
- Cross the path: /data/data/com.miui.clipboard/shared_prefs/
- Delete the files: clipboard_history.xml โ history; clipboard_images (folder) - copied images; miui_clipboard_config.xml โ buffering.
Reboot your smartphone.
Without root rights, you canโt delete files directly, but you can clear the clipboard app cache through Settings โ Apps โ All Apps โ Clipboard โ Storage โ Clear the cache. This will delete the temporary data, but not the history.

โ ๏ธ Note: Delete files in /data/data/ If the clipboard stopped working after cleaning, restore factory settings or reflash the smartphone through the Mi Flash Tool.
Method 4: Disabling clipboard history in MIUI
If you don't want to clean up the clipboard regularly, you can turn off its history completely, which will prevent you from saving the data that you're copying, but it won't delete the records that you already have.
- Open Settings โ Additional โ Language and input โ MIUI keyboard.
- Select Keyboard Settings โ Additionally.
- Turn off the option to save the history of the clipboard.
- For a complete reset, restart your smartphone.
Some firmware has this parameter hidden to activate it:
- Turn on Developer Mode (7 times tap the MIUI version in your smartphone settings).
- Back to Settings โ Additionally. โ For developers.
- Activate Show Hidden MIUI Settings.
- Now the clipboard option will be available in the keyboard settings.
Resetting instructions:
- Back up important data via Settings โ About Phone โ Backup.
- Go to Settings โ About the phone โ Reset settings.
- Choose to erase all data and confirm the action.
- After the reboot, set up your smartphone as new.
โ ๏ธ Attention: Redmi 7 with firmware MIUI 12.5 and later resetting may not clear the clipboard if sync with Mi Cloud is enabled. โ Xiaomi account โ Synchronization.

Resetting to factory settings is the only way to guarantee that you will remove all traces of the clipboard, including data synchronized with the Mi Cloud, but after this procedure you will have to reconfigure the smartphone.
Additional Security Tips for the Exchange Buffer
To minimize the risk of data leakage through the clipboard on Xiaomi Redmi 7, follow these guidelines:
- ๐ Turn off cloud sync: Go to Settings โ Xiaomi account โ Mi Cloud and deactivate the option of Clipboard Sync.
- ๐ก๏ธ Use clipboard managers: Install applications like Clipboard Manager or Clip Stack that encrypt copy history.
- ๐ซ Disable access to the buffer for third-party applications: C Settings โ Annexes โ Permits โ Access to the clipboard disable rights for all programs except system.
- ๐ Reboot your smartphone regularly: This clears temporary buffer data that is not deleted via the standard menu.
If you often work with sensitive information (passwords, bank details), consider using a virtual keyboard with a self-cleaning buffer, such as Fleksy or Chroom. These applications do not save copy history and automatically erase data after insertion.
