Users of smartphones Xiaomi, Redmi and POCO Sometimes they encounter an unusual artifact: a translucent window with code containing tags like <div>, <table> or <iframe>. This phenomenon is often called “viewing”. HTML», causes confusion and panic, as it can overlap important elements of the interface or simply interfere with the normal use of the device.
In most cases, this is not a virus and not a sign of hacking a gadget, but a specific debugging mode or a system shell bug. MIUI (The system debugger can be activated accidentally when you update applications or after resetting settings. In this guide, we will explain in detail why it appears. HTML-code over the interface and what methods can be guaranteed to remove it.
It's important to understand that the elimination methods depend on the specific firmware version and model of your smartphone. The engineering menus on different devices look different, but the logic of the work remains similar. We'll look at both software methods through standard settings, and deeper methods that require attention to detail.
Causes of the occurrence HTML-screen-code
The fundamental reason for tagged text on the display is that the user interface debugging mode is activated. Xiaomi developers use special tools to check the layout of system windows, and sometimes these tools pop up for ordinary users, this can be due to an error in the process of updating the system or a conflicting system application.
Often the culprit is Show Surface Updates or similar options in the developer menu, and when this option is enabled, the system highlights the boundaries of windows and layers, which can visually look like a set of obscure tags, and it can also cause incorrect work of the system if you installed third-party designs.
⚠️ Warning: Don't rush to do a full Hard Reset if you see the code on the screen. 90% of the time, the problem is solved by changing one setting in the developer menu, and your files will remain intact.
Another factor is third-party applications that require permission to “paint over other windows.” Software like blue light filters, weather widgets, or memory cleaners can conflict with Android system processes, causing visual glitches. HTML-The code appears due to a damaged system cache UI.
Here are the main triggers that can trigger this mode:
- 🔌 Accidental multiple clicks on the build number in the section "About the phone».
- 📲 Install applications from unreliable sources (APK-file).
- 🔄 Interrupted or incorrect firmware update MIUI.
- 🎨 Conflict of the established third-party theme of design.
Disabling debugging mode in the developer menu
The most effective way to remove the intrusive HTML-code is to check the settings for developers, and that's where the switches that debug the GUI are hidden, and even if you didn't consciously turn on that mode, it could activate automatically after the update.
First, you need to get into the hidden menu. Go to Settings. → About the phone and find the line "Version" MIUI» (or "Version" OS»). Press it quickly. 7-10 once until the notification "You became a developer" appears, then go back to the main settings menu, select Additional → For developers.
Within this vast list, you'll find a section that deals with hardware acceleration or rendering. Look for items with names like "Debugging USB," "Show touches," or "Display controls." Graphic debugging is often hidden under "Drawing" or "Hardware Accelerated Rendering."
☑️ Checking the Developer Menu
Pay special attention to the following parameters, which should be translated into the “Off” position:
- 🚫 Show surface updates (Show surface updates).
- 🚫 Force GPU rendering (forced processing) GPU).
- 🚫 Debug GPU view (Debugging) GPU view).
- 🚫 Profile HW Accelerated UI (Profile of hardware acceleration UI).
After changing the settings, it is recommended to restart the device. HTML-The code is gone, so the problem was in the rendering settings. If you don't have the developer menu available or the items are already off, move to the next section.
💡
The main goal is to find and disable any options that contain the words “Debug”, “Layout”, “Surface” or “GPU” in the developer menu.
Resolving the conflict of systemic themes
Shell MIUI It's known for its deep customization, but sometimes third-party themes downloaded from Themes store contain code errors, and if you've recently changed designs or installed themes from third-party authors, they can cause the appearance of a new source of information. HTML-tags on the desktop or menu.
To test this hypothesis, you need to temporarily return the standard theme. Go to the Topic app, go to the profile (human icon) and select "My Topics." Find a theme called "Classic," "Default" or "Standard" and apply it. After application, the system will redraw the interface, and the error should disappear.
If the standard theme didn’t work, try clearing the Topic app itself. To do this, go to Settings → Apps → All Apps, find Topics, and click Clear → Clear All. This action is safe and won’t delete your personal photos or contacts.
⚠️ Note: When you reset the Themes app, you may reset your widget and font settings. Save screenshots of an important desktop configuration in advance if it is critical to you.
In some cases, the problem is not the theme itself, but the wallpaper plugin. HTML5-It's a rendering engine, and if you crash the script, the code is displayed on the screen. Try to set the static image as wallpaper to eliminate this factor.
Cleaning the system interface cache
Accumulation of temporary files or damage to the cache of system services is a common cause of visual artifacts. In an Android environment, the System Interface process is responsible for displaying desktops, menus and status bars. UI). Cleaning it often solves the problem without losing data.
To do this, go to Settings → Applications → All Apps. In the list, find System Interface (can be simply called System UI or System Services). Click on it, then select Memory and Clear Cache. Don't confuse it with Clear All, although this is also safe, but it can reset icons.
After cleaning the cache, the phone can flash the screen for a short time — that's normal, it reboots the graphics shell. HTML-The code is still there, try to clear the cache of the Security app as well, since in the MIUI It is closely integrated with the system.
Procedure for deep cleaning:
- 🗑️ Clear the cache of the application "System interface».
- 🗑️ Clear the cache of the application "Security».
- 🗑️ Clear the cache of the application "Conductor».
- 🔄 Perform a complete reboot of the device.
💡
If after cleaning the cache, the problem comes back after a while, check if you have an optimizer application or an antivirus from a third-party developer installed. UI.
Comparison of methods of solving the problem
Not all methods are equally effective in every situation, and the choice of method depends on how the error manifests itself: whether the code is constantly hanging or only appears in certain applications. Below is a table that helps you choose the best strategy.
| Symptoms. | Probable cause | Recommended method | Difficulty |
|---|---|---|---|
| The code is always visible, even on the desktop. | Debugging mode GPU/Interface | Developer menu | Low. |
| The code appears in only one program. | Application-specific bug | Reinstallation of the annex | Low. |
| The code came after the subject change. | Theme error | Resetting the topic to the standard | Low. |
| Code blinks or twitches | System UI Cache Conflict | Clearing the cache | Medium |
| Nothing helps, the code stays. | Deep system failure | Reset to factory settings | Tall. |
As you can see from the table, most of the time, simple actions are enough. However, if none of the soft methods worked, the system files of the firmware may be damaged. In such a situation, the only guaranteed solution is a complete reset (Wipe Data), but it should be resorted to only as a last resort.
Before drastic measures, always try Safe Mode. To do this, press the Off button, and when the Off menu appears, press and hold your finger on Turn Off (or Reset, depending on the version of MIUI) until you are prompted to switch to Safe Mode.
Prevention and safe regime
Safe Mode is a diagnostic tool that only downloads system applications, disabling all third-party applications. HTML-The code does not appear, so the problem is exactly in one of the applications you installed.
Once you're out of Safe Mode (just restarting your phone in the usual way), start removing newly installed programs. Pay special attention to launchers, widgets, and memory cleanup applications. Delete them one by one and check the results.
How do you get out of safe mode?
To prevent the occurrence of such problems in the future, follow simple rules:
- 🛡️ Do not install themes and apps from unknown sources.
- 🔄 Update the system regularly through the official menu.
- 🚫 Do not include features in the developer menu if you do not understand their purpose.
- 📱 Keep an eye on the free space in the device memory.
⚠️ Note: If you use custom launchers (Nova, Lawnchair, etc.), try temporarily removing them and returning to the standard launcher. MIUI. They often conflict with system overlays.
