Many Xiaomi smartphone users are faced with the mysterious appearance of a “KB” label or icons indicating the amount of memory they are taking, directly on top of the desktop or in the interface. Most often, this means either an active clipboard that shows copied text, or visualizing cached data from applications occupying precious space. MIUI and the new HyperOS have many layers of interface, and sometimes standard indicators begin to interfere with the full use of the gadget.
There are several ways to remove these elements, depending on the specific cause of their occurrence: whether it is a system error, the operation of the clipboard or a crowded cache of the system. It is important to understand that the KB is not a virus, but technical information that should normally be hidden from the user's eyes. In this article, we will discuss all methods for cleaning and hiding unnecessary interface elements.
Before we start taking radical measures, we need to make a basic diagnosis of memory status. Often users confuse the clipboard indicator with the real memory, although these are different processes. Below we will look at how to pinpoint the source of the problem and fix it.
The first step is always to determine what is displayed on the display. If you see a floating window with text or data size, it can be a function of the “floating window” of the clipboard or a specific widget of the system. In some cases, this is the result of third-party launchers or themes that incorrectly display system notifications. Check whether you have debugging mode or special features for developers who can display technical information on the screen. Also, you should pay attention to recent applications, especially those that work with third-party launchers or those that have access to the buffer from the analysis system. If the inscription appears only in certain applications, such as in a browser or messenger, the problem may lie in the cache of this particular software. In this case, global cleaning of the phone will not be required, it will be enough to spot work with the settings of a particular application. 🔍 Check the settings of “Special features” for active scripts. 📱 Make sure that the developer mode with profiling enabled is not running. 🧹 Run the standard Security app for the initial scan. 📊 Where exactly do you have the inscription KB?On the desktop Inside the applications In the curtain notifications Constantly over all windows
Cleaning the clipboard and floating windows
The most common reason for text or data-related labels is a crowded clipboard. Xiaomi and Redmi shells have a built-in buffer manager that stores the history of the copied one. To remove the visual display, you need to clear that history.
Go to any type field, such as a browser search bar or notes. Press and hold your finger until the menu appears. Select the clipboard icon (usually looks like a notebook or list). In the menu that opens, find the cleaning button or basket icon. This action will delete all saved fragments and remove the associated notifications.
⚠️ Warning: Clearing the clipboard will remove the entire history of copied text. If you have important passwords or card numbers stored there, copy them to a safe place before cleaning.
It's also worth checking the keyboard settings. If you're using Gboard or SwiftKey, they may have their own floating prediction bars or buffers that appear on the screen. Turn off the "Show Clipboard" feature in the keyboard settings themselves to spare the screen unnecessary visual noise.
💡
Use third-party clipboard managers only from trusted sources, as they have access to all text you copy, including sensitive data.
Use of built-in MIUI and HyperOS cleaner
Xiaomi’s regular optimization tools are the safest way to delete temporary files and cache that can cause erroneous memory indicators.Security is deeply integrated into the system and knows which files can be deleted without risking stability.
Run the Security app and select Clean up. The system will analyze and prompt you to remove the Garbage. Press the Cleanup button. This action will make room and can remove erroneous indicators if they were caused by overflowing system logs or cache.
☑️ Complete cleaning algorithm
For a deeper cleaning, go to Memory in your phone settings, and you can see which apps take up the most space. If you see an app that you don't use but it takes hundreds of megabytes, go to its settings and select Clear Cache. Don't confuse that with the Clear All button, which will also delete your data inside the app.
| Type of data | Can be removed | Risk of data loss | Impact on the CB |
|---|---|---|---|
| Cash app. | Yes. | No. | High. |
| Application data | No (no backup) | High-pitched | Average. |
| Systemic debris | Yes. | No. | Low. |
| Downloads (Downloads) | Selectively | Medium. | Depends on the files. |
Memory Display Settings for Developers
If you have a string of numbers on your screen (like “45 percent” or a specific MB/CB volume), you’re likely to have Show Memory usage enabled, a developer tool that is accidentally activated by regular users.
To remove this line, go to Settings → About Phone and quickly click on MIUI Version (or OS Version) several times until “You’re a developer” appears. Then go back to the main settings menu, scroll down to “Additional” and find “For Developers.”
Inside the developer menu, scroll through the list almost to the end, find the Show Memory Use switch and turn it off, and then the extra string of numbers will disappear instantly from the top of the screen.
⚠️ Warning: Do not change other settings in the Developer Menu unless you understand their purpose. DPI or limit background processes can make the interface unreadable or slow down the phone.

Removal of third-party widgets and design themes
Often the source of the problem is the themes downloaded from the Themes store, or installed widgets weather, watches and memory cleanup. Some third-party “optimizers” like to put their logos or “acceleration” indicators on the screen, which display the amount of freed memory in the KB or MB.
Check your desktop for widgets called Clearer, Booster, Memory, or the like. (long press) this widget will remove it, and switch to the standard theme Classic or Default to see if the visual element is part of the customization.
If you’ve installed memory cleanup applications (Clean Master, DU Booster, and similar ones), consider removing them. In modern versions of Android and HyperOS, they’re often redundant and only add extra workload, and their widgets can conflict with the system interface.

- 📉 Turn off the widget display in No Hurry mode (if enabled).
Reset interface settings and reboot
Sometimes the problem is temporary and involves a software failure in the system process SystemUI. In this case, a simple but effective procedure for restarting the memory completely cleared helps.
Press the power button and select Reboot. If that didn't work, you can try a deeper method: clearing the launcher data. Go to Settings → Apps → All applications, find System Launcher (or System Launcher), select Memory and click Clear Data. Importantly, this will reset the desktop icons to factory appearance, but remove display errors.
💡
Rebooting in Safe Mode will help you determine exactly whether a third-party application is the cause of the appearance of the KB, and if the inscription is missing in Safe Mode, one of the applications you install is to blame.
If none of the methods worked, there may be a more serious firmware failure, in which case it is recommended to check for system updates in the About Phone menu. Xiaomi engineers regularly release patches that fix such visual bugs.
