Where is the exchange buffer for Xiaomi: a complete guide to MIUI

The clipboard on Xiaomi smartphones is one of those tools that many users don’t even know exists until they’re faced with the need to find text or image that they’ve copied before. Unlike iOS or standard Android, the MIUI shell offers advanced copy history capabilities, but not always obvious: where to look for the buffer, how to turn it on, and why sometimes the copied data “disappears” – questions that depend on the firmware version, device model, and even regional settings.

Many people mistakenly believe that the clipboard on Xiaomi is just temporary storage for one last copy, as on most Android devices. However, MIUI 12 and later integrated a full clipboard manager with a history of up to 20 records, synchronization between devices (linked to one Mi Account), and even the text recognition feature on screenshots. The problem is that this feature is often disabled by default or hidden in non-obvious menu sections.

If you use Xiaomi at work or school, quickly managing copy history can save hours of time, like tapping text you copied an hour ago or finding a link you “save somewhere.” But there are pitfalls: some models (especially the budget Redmi series) lack advanced features, and MIUI 14+ has changed the logic of the buffer, so the first thing to do is figure out which version of the firmware you’ve installed on your device.

Where the exchange buffer is physically stored on Xiaomi

Unlike files or photos, the clipboard does not have a separate folder in the device’s memory.The data is stored in RAM (RAM) and in the system cache, which is managed by the com.miui.clipboard service.This means that after rebooting the smartphone or clearing the cache through Settings → Memory copy history can be reset. However, in MIUI 13+, some of the data is duplicated in the cloud if sync with Mi Account is enabled.

The physical path to buffer files (if any) is as follows:

/data/data/com.miui.clipboard/databases/clipboard.db

But access to this folder is only possible with root rights or through ADB. For the average user, it is easier to use built-in shell tools.

It is important to understand that the clipboard is divided into two types:

• 📋 Local buffer – stores data only on the current device, resets when restarting.
• ☁️ Cloud buffer (available in MIUI 12+) — Syncs between devices via Xiaomi account.

On models Redmi Note 10/11/12 and flagship Xiaomi 12/13/14 cloud buffer works stable, while on older devices (for example, Redmi 9A) may be absent at all.

💡

If you often copy important data (passwords, card numbers), use third-party applications like Clipboard Manager or Clip Stack – they save the history in encrypted form and do not depend on the reset of MIUI.

How to open the clipboard in MIUI: 3 official ways

Why the clipboard doesn’t work: Common mistakes

If the copy history is not displayed or reset, the problem may be in settings, application conflict, or system errors.

A critical feature of MIUI 14 HyperOS is that the clipboard is now integrated with the Mi Share function, and if you turn off this service, the copy history may stop working. To check its status, go to Settings → Connections and Sharing → Mi Share and make sure that the option is active.

Another common mistake is to conflict with garbage cleaning applications (like Security or Clean Master), which often delete the clipboard cache as "data inappropriate."

⚠️ Note: Add com.miui.clipboard to auto-clean exceptions. → Annexes → Application management → Three dots (menu) → Special access → Clean and disable the buffer cleanup.
