Modern smartphones like the Poco X3 have become the primary tool for consuming content, whether it’s social media feeds, news articles or instant messaging. Often, it’s necessary to save not just one frame, but several screens of information at once to convey the context of the dialogue or the appearance of the entire site. A standard screenshot here will not help, since it trims the image along the physical boundaries of the display, leaving behind important information.
Fortunately, the MIUI shell on which Xiaomi and Poco devices are based has a sophisticated scroll capture system that allows you to automatically glue multiple frames into one long band, keeping the text readable and the page structure intact, and you won’t need third-party apps or complex computer manipulations, as all the necessary tools are already built into the system.
In this guide, we will take a detailed look at all the available ways to create advanced screenshots, discuss the nuances of working with different types of content and answer frequent questions that arise from owners of Poco X3 NFC and Poco X3 Pro. You will learn how to quickly save long contact lists, correspondence in WhatsApp or Telegram, as well as full versions of web pages.
Device preparation and basic settings
Before you start taking complex shots, you need to make sure your device is functioning correctly and has up-to-date system updates. Scrolling may not work properly on very old versions of Android or MIUI, so checking for updates is the first step. Go to Settings → About Phone and click on the logo version of the system.
It's also worth freeing up some space in the gallery's memory. Long screenshots, especially in high resolution, can take up significantly more space than normal images. If the storage is crowded, the process of gluing the frames can be interrupted or ended in error.
Make sure the display settings don't set extreme font or scale values that can disrupt the layout when glued.Poco X3's standard settings are optimal for this task, but if you've changed the font size in the Settings → Screen menu, try returning them to default values.
It is important to understand that the long screenshot function is not only system-dependent, but also application-specific. Some secure applications, such as bank clients or incognito browsers, can block the creation of any screenshots, including those that are scrolled, for security reasons.
⚠️ Note: If you use third-party themes or modified fonts, the screenshot preview function may not work smoothly. If you have problems, go back to the standard Poco Launcher theme.

Before you create an important long screenshot, close the background apps so the system can allocate more RAM to process the image.
Creation through a combination of buttons
The fastest and most common method for many users is to use a physical key combination. The Poco X3, like most modern smartphones without a mechanical home button, uses a combination of power and volume buttons, a method that is universal and works in almost any situation where the screen is not locked.
To create a picture, you need to press the Volume Down and Power buttons simultaneously. The press should be short, almost tangential. If you hold the buttons too long, the phone may perceive this as a command to call the emergency services menu or turn off the device.
Immediately after the shutter clicks, a thumbnail of the screenshot will appear in the upper right corner of the screen, and that's when, while the thumbnail is still visible on the display, you click on the Scrolling button (the icon with the arrows down) that appears below the image, and then the system will automatically start capturing the content below the visible area.
You can stop the scrolling process at any time by tapping the screen or pressing the stop button, which will appear instead of the continue button, and this allows you to capture exactly the length of content you need without going to the bottom of the page.
☑️ Algorithm of actions by buttons
Use of control panel (Curtains)
If using physical buttons is difficult or uncomfortable, MIUI offers an alternative through the control center, especially when it is difficult to press two buttons at once with one hand, or if the device buttons are stiff.
To start, swipe the notification curtain down from the top of the screen. In the shortcut set, find the screenshot icon. If you can't see it in the front row, click on the edit button (usually a pencil or three dots) and drag that shortcut to the active zone.
After clicking on the virtual button, the system will take a picture of the current screen, and, as in the previous case, a floating window with a preview will appear in the corner. The scroll trigger is identical: you need to quickly click on the scroll button in the menu that appears.
The advantage of this method is that it eliminates the risk of accidentally clamping the buttons and then turning off the phone, and you can also assign other activation methods through the shortcut settings, such as tapping on the back panel or swiping with three fingers.
Voice control of Google Assistant
Poco X3 owners can use Google Assistant’s built-in voice assistant to take screenshots, especially when hands are busy or the phone is attached to the holder, and it works stably and supports commands in Russian and English.
Activate the assistant with the phrase "OK, Google" or long press of the power button (if this feature is enabled in the settings). clearly pronounce the command "Take a screenshot" or "Creeenshot." The system will capture the current screen.
Unfortunately, at the time of writing, there is no direct voice command for a long, automatic scrolling screenshot in the standard assistant, but once you have a regular voice screenshot, you can quickly go to edit it. In some versions of MIUI, an editing interface appears after the voice command, where you can manually start scrolling.
This method requires a stable connection to the Internet, since voice commands are processed on Google servers, and if the network is unstable, the phone may not recognize the command or execute it with a long delay.
⚠️ Warning: Voice control may not work in high-security applications or full-screen games where system interfaces are hidden.
Editing and saving long shots
Once you have created a long screenshot, the system will prompt you to save it. Before the final save, it often becomes necessary to framing, since automatic scrolling can capture unnecessary elements of the interface from the bottom or top.
Click on the thumbnail of the finished image to open the editor. Use the Crop tool to cut out the extra fields. You can choose the standard proportions or move the frames, leaving only the desired part of the text or image.
The editor also includes the addition of notes, text or blurring sensitive information. The Marker or Text tool allows you to highlight key points in a long screenshot, making it more informative for the recipient.
When saving, pay attention to the format. By default, Poco X3 saves screenshots in PNG format, which provides high quality without losing details, but has a larger file size. If you need to send a screenshot through a strong compression messenger, you can convert it to JPG through third-party editors, although the staff gallery does not have this option.
Why can the screenshot be black?
Typical problems and their solution
Despite the system's fine-tuning, users may find themselves in situations where the scroll button doesn't appear or the screenshot is cropped. One common reason is the lack of scrollable content. If a page or chat is fully placed on a single screen, the system simply has nothing to glue together.
Another problem is dynamic content: In some news feeds or infinite scroll applications, new elements are loaded only when they reach the bottom of the screen. The screenshot algorithm may not be able to load the content, and gluing is interrupted.
Also consider the length limits. Android and MIUI have a technical limit on the maximum height of the picture (usually a few tens of thousands of pixels), and if you try to capture a very long dialog, the system will force you to stop scrolling when you reach that limit.
The table below shows the main symptoms of problems and how to eliminate them:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| No scrolling button. | Content is not scrolling | Check if there is hidden text below. |
| Black screenshot | Application protection | Take a screen photo with another device |
| Breaking the gluing | Memory deficit | Clear RAM and storage |
| Crooked seams | Animation of transitions | Disable animations in the developer settings |
💡
The maximum screenshot length is limited by the technical capabilities of the image processing processor and is usually about 5-10 screens in a row.
Where to store and how to share results
All screenshots, including long ones, are automatically saved to the DCIM/Screenshots or Pictures/Screenshots folder in the device's internal memory, and are placed in a separate Screenshots album in the Gallery app, where they are easily found by date of creation.
When sending such files, consider their size. A long screenshot in high resolution can weigh 5-15 MB, which is critical for email attachments or messengers with limits. Telegram and WhatsApp when sent as “Photos” strongly compress the image, making small text unreadable.
To transfer important documents or long correspondence, it is better to use the Document function in messengers or cloud storage (Google Drive, Yandex.Disk), which will preserve the original quality and readability of fonts even with a strong increase in the recipient.
If you plan to work with long images often, it makes sense to install an optimizer or compressor application that reduces the weight of the file without any visible loss of quality, which will speed up their transfer over the mobile network.
⚠️ Attention: When you delete screenshots through the Recycle Bin in the Gallery, they are permanently erased after 30 days.
