The clipboard is one of those invisible but critical smartphone features that users only remember when it suddenly stops working. On Xiaomi phones with a MIUI shell, this tool is implemented in an unobvious way: it not only copies text or images, but also stores the history of operations, syncs with the cloud, and sometimes even disappears after updates. If you ever lost a copied password or an important piece of code due to a buffer reset, this article will help you understand the mechanisms of its operation and learn how to manage it effectively.
Unlike Android in its pure form, where the clipboard is a temporary storage of the “last copied”, in MIUI it is turned into a full-fledged manager with history, search and even the ability to fix frequently used elements. However, this functionality has the opposite side: history can take up excess memory, synchronization with Mi Account is not always stable, and after resetting the buffer is cleared without the possibility of recovery. Next, we will analyze where the clipboard is physically stored in Xiaomi phones, how to find it in different versions of MIUI (from 12 to 14), and what to do if it stops working.
What is a clipboard and how does it work for Xiaomi
The clipboard is a temporary storage device that allows you to transfer information between applications, and it works differently in Xiaomi than it does on most Android devices:
- 📋 Standard Android: only stores the last copyed item (text, image, link) and then deletes the previous data after the new copy.
- 📚 MIUI Clipboard: saves the history of the last 20–50 elements (depending on the model and firmware version), supports search and fixing important records.
- ☁️ Cloud sync: Linked to Mi Account, buffer history can be transferred between devices (e.g. from smartphone to Xiaomi tablet).
It’s important to understand that the clipboard in MIUI is not just a technical feature, but a separate system application (com.miui.clipboard) that can be turned off or reset, its data is stored in a protected memory area, but remains vulnerable to resetting or manually clearing through Settings → Applications.
How does this work in practice? For example, you copied a phone number from WhatsApp, then an address from Google Maps, and a snippet of code from Telegram. In standard Android, only the code will remain in the buffer, and in MIUI, all three elements that can be returned even after a few days (unless automatic cleaning occurs).
Where the clipboard is stored in Xiaomi phones: physical location
The clipboard files in MIUI are scattered across multiple folders, and their location depends on the firmware version.
| Type of data | The way in the system | Access without root |
|---|---|---|
| The local history of the buffer | /data/data/com.miui.clipboard/databases/clipboard.db | ❌ No. |
| Cash images. | /data/data/com.miui.clipboard/cache/ | ❌ No. |
| Synchronization settings | /data/data/com.xiaomi.account/shared_prefs/ | ❌ No. |
| Backup copies (with manual backup) | /sdcard/MIUI/backup/AllBackup/ | ✅ Yes. |
⚠️ Note: Trying to manually edit files in a folder /data/ without root rights, you'll have an access error. Even with root rights, you don't want to change clipboard.db, because it can disrupt the buffer. → Memory. → Backup.
If you need to transfer the buffer history to another Xiaomi device, the easiest way to do this is to:
- Enable synchronization with Mi Account (in buffer settings).
- Sign in to a new phone under the same account.
- Wait for the history to be downloaded automatically (it can take up to 10 minutes).
💡
To speed up buffer synchronization between devices, turn on mobile internet before logging in to your account on your new phone (Wi-Fi sometimes blocks MIUI background processes).
How to open the clipboard on Xiaomi: step-by-step instructions
Depending on the version of MIUI (12, 13 or 14), the way to access the clipboard may vary, and the following are the current instructions for all modern firmware.
MIUI 14 (2023–2026)
In the latest version of the clipboard shell, the clipboard is integrated into the quick toolbar:
- Open any text field (for example, in Messages or Notes).
- Keep your finger on the floor until the menu appears.
- Click on the clipboard icon** (the icon of two documents) in the top panel.
- Before you will open the history of copied elements with searchability (magnifying glass in the upper right corner).
MIUI 12/13 (2020–2022)
In these versions, the buffer is hidden deeper:
- Go to Settings → Additional → clipboard.
- Or: Open the keyboard (like Gboard), click on the icon «⚙️» → «buffer»**.
- In some models (such as the Redmi Note 10 Pro), the buffer history is only available through long-term clicking on the text box.
Copy any text (e.g. this sentence)| Open buffer history as instructed above | Check if copied text is displayed | Try pasting it into another app-->
⚠️ Note: On certain devices (e.g, POCO F3 Custom firmware, the clipboard can be disabled by default. To activate it, go to Settings. → Annexes → Application management → Three dots (menu) → Show system-based → Clipboard and turn it on.
Why the clipboard doesn’t work: 5 main reasons
If the buffer history suddenly clears or stops opening, the problem usually lies in one of the following reasons:
- 🔄 Update MIUI: After major updates (e.g., version 13 to version 14), the buffer history is reset.
- 🧹 Cache Clearing: When manually clearing com.miui.clipboard application data via Settings → History is erased without the possibility of recovery.
- ☁️ Mi Account problems: If sync is disabled or account logged, cloud buffer history becomes unavailable.
- 🛠️ Optimizing the battery: MIUI aggressively closes the background processes. If the buffer doesn't update, check Settings → Battery → Optimize your battery and remove Clipboard from the list.
- 📱 Keyboard conflict: Third-party keyboards (like SwiftKey) can block access to the system buffer.
The most common situation is that the user copies important text (for example, a confirmation code from an SMS), but when trying to insert its field is empty. 80% of the time this is due to the fact that MIUI restricts access to the buffer for some applications (especially banking or messengers with screenshot protection).
- Copy the text into Notepad or Xiaomi Notes.
- From there, insert it into the target application.
How to Recover Buffer History After Resetting
How to Clean Up Xiaomi’s Clipboard: Full Instruction
If the buffer history is full of unnecessary data (such as old passwords or sensitive information), it can be cleared in several ways:
Method 1: Through buffer settings

Hidden Exchange Buffer Functions in MIUI
Few people know, but the clipboard in Xiaomi can do more than just store text. Here are some useful tips:
- 📌 Elements Fixing: Long-Tap on Any Record in History → «Secure. Such elements shall not be removed by automatic cleaning.
- 🔍 History Search: At the top of the buffer screen, there is a search bar. You can search by keywords (e.g., "password" or "address»).
- 📤 Export History: In Buffer Settings → Exports can be saved to a.txt file (easy to port to PC).
- 🔄 Synchronization with PC: If the computer has the Mi application installed PC Suite, copied text on the phone can be inserted directly into Word documents or browser.
- 🖼️ Image support: Not only text can be copied to the buffer, but also screenshots or photos (hold your finger on the image). → «Copy»).
One of the most useful features is the quick creation of notes, and if you copy text (such as a recipe or instruction), it can be instantly saved in Xiaomi Notes:
- Open the history of the buffer.
- Find the right item and swipe to the left.
- Select “Create a Note”** and the text will automatically be saved in the Notes app.
There's also a hidden translation function in the buffer, and if you copy a phrase in a foreign language, you'll see an icon in the story «🌐»** — Click on it to see the translation via Xiaomi Translate (works offline for major languages).
Clipboard security: how to protect your data
The clipboard history can contain sensitive information, such as passwords, card numbers, private messages, and there are several ways to protect this data at MIUI:
⚠️ In 2023, security researchers discovered a vulnerability in the MIUI Clipboard, which allows attackers to intercept copied data through malicious apps. Xiaomi released a patch in a July 2023 update, but if your phone hasn't been updated in a long time, check the firmware version in Settings → About the phone and install the latest updates.
If you often copy sensitive information (such as two-factor codes), use password managers (such as Bitwarden or KeePassDX), which have their own secure clipboard, which automatically clear the copied data in 30-60 seconds.
