Long screenshot on Xiaomi Poco X3: all ways + problem solving

Xiaomi Poco X3 (including the NFC and Pro versions) remains one of the most popular smartphones among users who appreciate performance and functionality. However, the standard screenshot mechanism in MIUI limits the capture to only the visible area of the screen - what to do if you want to save an entire web page, correspondence in the messenger or a long list in the application? In this article, we will discuss all the working ways to create long (scrollable) screenshots on Poco X3, including hidden system functions, third-party applications and bypassing typical errors.

It is important to understand that the long screen features depend on the version of MIUI (12, 13 or 14) and the security patch installed. For example, in older builds the function is built into the system menu, and in new ones it can be hidden or removed. We tested all methods on Poco X3 with firmware V12.5.3.0.RJGMIXM (Android 11) and V14.0.4.0.TJGMIXM (Android 13) - the results are summarized in the comparison table below.

1. built-in long screenshot feature in MIUI

The most obvious way is to use the native MIUI tool, which is activated after you create a regular screen.

• 📱 It works only in supported applications (browser, Telegram, WhatsApp, some system menus).
• ⚙️ V MIUI 14 function can be disabled by default – manual activation is required in settings.
• 🚫 Does not work in games, some social networks (for example, VKontakte) and applications with dynamic content.

How to do this:

1. Take a regular screenshot with the combination of Volume Down + Nutrition.
2. In the preview that appears at the bottom of the screen, tap on the “Scroll” icon (two arrows down).
3. Wait for the page to automatically scroll. To manually stop, tap the screen.
4. Save the result with the "Ready" button.

⚠️ Note: If the Scrolling icon does not appear, check if the feature in Settings is disabled. → Additionally. → Screenshots → Long screenshot. MIUI 14 Ways may be different: Settings → Annexes → Special permits → Display over other apps (you need to enable Screenshot for your system application).

If necessary, enable permission in the settings-->

2. Third-party applications for long screenshots

If the built-in tool doesn't work or it doesn't cover your needs, third-party tools come to the rescue. We tested 7 popular apps, and the best results were:

Recommendation: LongShot is optimal for most tasks: Install it from Google Play, grant permissions to Display over other apps and Accessibility Service.

1. Open the desired application/page.
2. Run LongShot from the notification panel.
3. Select the Auto Scroll or Manual mode.
4. Set your scroll speed (recommended Medium for Poco X3).
5. Save the result to the gallery or PDF.

💡

If the app doesn’t see content in the browser, try enabling the developer mode in Chrome (chrome://flags/#enable-android-web-contents-dark-mode) and restarting the page.

3. Hidden function through ADB (for advanced)

If you need to take a long screenshot in an unsupported application (for example, in banking software or a game), you can use the app. ADB-This method requires you to connect your smartphone to your PC, but it gives you complete control over the process.

What you need:

• 🖥️ Computer with installed ADB Tools.
• 🔌 USB-cable (preferably original).
• 📱 Included debugging by USB Poco X3 (Settings → The phone. → Version. MIUI — Tap 7 times, then go back to Settings → Additionally. → For developers → Debugging by USB).

Step-by-step:

adb shell


su




/system/bin/screencap -p /sdcard/longshot.png




exit




adb pull /sdcard/longshot.png C:\Users\YourName\Desktop

For a scrolling screen, use a Python script with a uiautomator library (an example of the code is in the repository), the only method that works in 100% of applications, including secure ones (for example, SberBank Online or Tinkoff), but requires command-line skills.

⚠️ Attention: Use ADB This can result in a data reset if you interrupt the process while executing commands with su rights. Always back up through adb backup before experimenting.

4. circumvention of restrictions in MIUI 14

In the latest versions of MIUI 14 (especially on the Poco X3 Pro with Android 13), the long screen feature may be blocked due to Xiaomi's security policy.

Method 1: Through the Developer's Settings

1. Activate the Developer Mode (as described in the previous section).
2. Go to Settings → Additional → For developers.
3. Find the option "Deactivate restrictions" MIUI" (or "disable" MIUI Optimization" and activate it.
4. Reboot the phone.

Method 2: Termux (without root)

Install Termux and execute commands:

pkg update && pkg upgrade


pkg install tsu




termux-setup-storage




tsu




settings put global hidden_api_policy 1

After the reboot, check for the Scrolling icon in the screenshot preview. If the method didn't work, try an alternative method to change the configuration file /system/build.prop (requires Magisk).

5. Solving typical errors

Even with the right settings, Poco X3 users are facing problems.

If the problem persists, check:

• 📵 Power saving mode - turn it off in Settings → Battery.
• 🔄 System updates – in some cases, bugs are fixed in new patches.
• 🛠️ Resetting the settings of the "Screenshots" application (Settings) → Annexes → Application management → Screenshots → Warehouse → Reset).

6. Alternative methods: screencast and hand gluing

When all methods are exhausted, there are universal, but laborious methods:

Method 1: Screen recording + screen conversion

1. Enable screen recording through Settings → Screen → Screen recording.
2. Scroll the page manually, then stop the recording.
3. Use an online service to extract frames from videos and glue them.

Method 2: Manual gluing in Photoshop or Paint.NET

Take a series of regular scrolling screenshots and combine them:

• 🖼️ In Photoshop: File → Scripts → Upload files to the stack, then edit → Automatic layer alignment.
• 🎨 In Paint.NET: Use the “Panorama” plugin from the Effects menu.

⚠️ Attention: When hand gluing, watch for resolution of the final image. X3 screen-resolution 2400×1080 maximum length of screen without loss of quality — ~20 000 Exceeding this value can lead to artifacts while preserving the JPEG.

7. Comparison of methods: which to choose?

To determine the best way, we will evaluate each of them according to the key criteria:

Conclusion:

• For a quick screen in supported applications (browser, messengers) will be enough built-in function.
• For versatility (including games and banking applications) LongShot or ADB is suitable.
• For maximum quality (for example, for printing) – hand gluing in the graphics editor.

💡

On the Xiaomi Poco X3 with MIUI 14, the built-in long screen function is unstable. The optimal balance of speed and versatility gives a combo: LongShot for most tasks + ADB for "severe" cases.
