How to take a screenshot on Xiaomi, if the application prohibits

Xiaomi, Redmi and POCO smartphone owners often face a situation where a characteristic sound is heard when trying to save a screen image, but the image itself does not appear in the gallery. MIUI or HyperOS system issues a message that the action is prohibited by the security policies of a particular application. This is standard protection for banking programs and streaming services, but it can be annoying when you need to urgently fix information.

Normally, standard button combinations are locked at the Android operating system level in these cases. However, there are workarounds that allow you to get the desired image. Some methods require you to connect to a computer, others work directly on the device. The choice of method depends on the version of your firmware and the level of access you are willing to provide to the system.

In this article, we will discuss effective ways to circumvent restrictions, we will look at both the standard system tools and more advanced technical solutions, and it is important to understand that bypassing security in banking applications can violate their user agreement, so use this knowledge carefully and only for legitimate purposes.

Why the system blocks the creation of screenshots

The main reason for the blockage is the flag. FLAG_SECURE, When that flag is active, the Android operating system prevents the capture of window content, and this is done to protect sensitive data: passwords, account balances and personal correspondence.

Xiaomi also has an additional layer of protection called MIUI Security, which scans running processes and forcibly disables screenshots in apps labeled as financial or containing secure content, often not only for banks, but also for some incognito messaging apps.

The locking happens at the rendering level, and even if you manage to take a picture through third-party software, you get a black square at the output, and it's not a mistake, it's a planned security behavior, and understanding this mechanism is important for choosing the right method of bypassing.

⚠️ Warning: Attempts to modify the system files of banking applications to remove protection may result in the blocking of your account by the bank’s security service.

Use of guest mode or second space

One of the easiest and safest ways to get around the ban is to use the "Second Space" function or guest mode, and the essence of the method is that some applications do not recognize launch in an isolated environment and do not activate the protection flag. You need to create an additional user profile in the system settings.

To do this, go to Settings → Advanced Settings → Second Space. After you create a profile, log in and install the application you need again. Log in to your account. Often in this mode, the system does not apply strict safety rules, and the standard combination of buttons Loud down + Power works normally.

This method is especially effective on older versions of MIUI, where space separation is less strict. In the new HyperOS updates, developers have begun extending security policies to guest profiles, so it may not always work.

📱 Create a second user profile through phone settings.
🔓 Enter guest mode and launch the app there.
📸 Try to take a screenshot with standard buttons.
🔄 If you don’t, switch back and check the main profile gallery.

📊 Do you have a screenshot in the second space?

Yeah, it works perfectly.

It works through the app.

No, it's black, too.

Debugging method by USB and ADB commands

The most reliable technical method is the use of Android Debug Bridge tools (ADB). This method allows you to send commands directly to the system, bypassing standard interface constraints. You will need a computer (Windows, macOS or Linux) and USB-You need to activate the developer mode on the phone.

First, turn on the debugging. USB. Go to Settings. → About the phone and 7 times click on the version MIUI. Then in the menu "Extended settings» → «For developers, include the “Debugging by” items USB» and “Debugging through USB (Security mode).” Connect your smartphone to your PC and install drivers.

After connecting, open the command line on your computer in the folder with ADB. Enter the command to create a screenshot and save it to internal memory:

adb shell screencap -p /sdcard/screenshot.png

Then download the file to the computer by command:

adb pull /sdcard/screenshot.png

This method bypasses software interface locks, since the command is executed at the kernel level of the system. ADB-They can block the execution of a command or display a black screen even in this case.

Comparison of methods of circumvention of protection

The right method depends on your technical background and the version of the operating system. Below is a table comparing the effectiveness of different methods on modern Xiaomi devices, which will help you quickly navigate which option is worth trying in your situation.

Method	Difficulty	Efficiency	The risk of blocking
Second space	Low.	Average (50%)	Absent.
ADB teams	Tall.	High (80%)	Minimum
Third-party annexes	Medium	Low (20%)	High-pitched
Screen recording	Low.	Low (10%)	Absent.

As you can see from the table, ADB remains the leader in efficiency, but requires preparation. The second-space method is good for its simplicity, but it works unstable. Third-party applications from the Play Market are often useless against modern banking protections, since they use the same system APIs that are blocked.

Use of emulators and remote access

If standard methods don't work, you can try running an application in an Android emulator on a computer, like BlueStacks or NoxPlayer. Security policies often work differently in an emulator environment, and screenshots are taken by the emulator itself. This bypasses lock-in at the phone level.

Another option is to use remote management applications like TeamViewer or AnyDesk running on another device, and you stream the locked app screen to another device and take a screenshot there, and the image is streamed through the video stream, and the flag is the same. FLAG_SECURE It may not apply to the outgoing video signal.

Why is the black screen on the record?

Some applications block not only static images, but also capture video streams, in which case you will also see black images when you record a screen or broadcast (DRM).> It is important to note that the current version of Android and MIUI They've learned to lock and capture windows in emulators, and banking applications can simply refuse to run if they're emulators or suspicious environments, so this is a fallback. ⚠️ Attention: Using emulators to log into banking applications can be regarded by the security system as an attempt to hack, which will lead to temporary blocking of access to the account. DRM-Separately, it is worth mentioning video services such as Netflix, ivi or Kinopoisk. Widevine technology is used here. DRM, And unlike banking applications, it doesn't just block the screenshot function, it blocks the entire output of the protected content when you try to capture it. DRM It's almost impossible to do this on a non-privileged device (without unlocked bootloader and root rights), and any applications that promise to do this are likely malicious, and if you see a black screen when you try to shoot a movie, that's normal license behavior. The only legal way to get a shot is to use the built-in Snapshot feature inside the app itself, if the developer has it, and some services allow you to take photos from the frame gallery that do not violate the image. DRM-protection, as these are pre-prepared images, not stream capture. 🎥 DRM-Protection blocks capture at the video driver level. 🚫 Root rights can disrupt work DRM, The video will stop playing in HD. 📸 Use built-in frame galleries inside movie apps. 📉 Decreased video quality sometimes helps bypass software blockers.Frequently asked questions (FAQ) Why do screenshots only turn black in some apps? It depends on whether the app developer has implemented a special security flag. FLAG_SECURE. Normal programs (browser, notes) don't have it, so screenshots work. In banks and movie theaters, it's on for data protection. Is it safe to use commands? ADB Using screencap is safe for data, because you're just copying the image. USB reduces the overall security of the device, making it vulnerable when connected to other computers. Will root rights circumvent the ban? Getting root rights (Magisk) gives you full access to the system, which theoretically allows you to ignore any flags, but banks and payment systems (Google Pay, Mir Pay) root immediately block their work. You have to keep your permissions hidden, which is a cat-and-mouse game. Can you take a screenshot from Google Assistant? It used to work, but it's now on Android and other versions of Android? MIUI Google Assistant also has system limitations, and trying to take a screenshot with a voice in a secure app will result in the same result — a failure or a black screen. 💡The most reliable way to do a single action is to use ADB For permanent use, it is better to negotiate with the developers of the application or use the web version of the service in the browser, where protection is sometimes weaker.
