How to scan. QR-Xiaomi phone screen code: all methods (including hidden ones)

Scanning. QR-The problem with code from another Xiaomi phone is that it seems simple at first glance, but it is often difficult. The problem is that most standard scanners cannot read codes from smartphone displays due to glare, low contrast, or screen flickering. This is especially true for devices with AMOLED-Matrices (e.g. Xiaomi 13 Ultra or Redmi) K60 Pro, where brightness and color reproduction distort the perception of the code by the camera.

In this article, we will discuss 5 working methods, including little-known functions MIUI, scanner QR-code even from the screen of another Xiaomi phone - without installing additional applications, POCO F5) android devices 13/14, So if you've seen the error before, "Code recognition failed," here's the solution.

Why the standard scanner can't see QR-Xiaomi screen code?

The main reason is the technical limitations of the cameras and the features of the display QR-And these are the key factors:

• 🔹 Screen flicker: Display refresh rate (e.g. 120Hz on Xiaomi) 12T) Creates a “stroboscope” effect that prevents the camera from focusing.
• 🔹 Low contrast: On AMOLED-The black pixels are completely turned off, which is why the boundaries are QR-“merge».
• 🔹 Autobrightness: Even with manual brightness adjustment, the system can adjust it to lighting, distorting the code.
• 🔹 Limitations of the FS: B MIUI 14 Scanning algorithm ignores dynamic objects (including screens) by default).

Also, if you’re trying to scan code from a locked screen (like for messenger authorization), the standard Xiaomi scanner just won’t start.

⚠️ Note: On Xiaomi models with infrared port (e.g. Redmi Note 11 Pro)+) scan QR-The code through the camera may conflict with the IR sensor. Before starting, disable the Infrared Port function in the Connection and Sharing settings.

Method 1: Built-in MIUI scanner (fastest)

1. Open the Camera and go to Additional (Icon) mode «⋯» Or "More»).
2. Select the Scan option QR-code (on some models — QR-scanner).
3. Hold the camera to the screen with the code at a distance of 10-15 cm and hold 2-3 seconds.
4. If the code is not recognized, tap the screen and manually focus on it.

On devices with MIUI 14 (such as Xiaomi 13 Lite), the scanning algorithm is improved, but it may be necessary to disable HDR in the camera settings.

1. In scan mode, tap the icon. ⚙️ (setting).
2. Turn off the Image Improvement or HDR option.

Method 2: Screenshot + Google Lens (for complex cases)

If the built-in scanner fails (e.g., on the POCO X5 Pro with MIUI 13), use Google Lens through a screenshot. This method works even with code on a locked screen:

1. Take a screenshot of the screen with QR-code (at the same time press the volume down) + Nutrition).
2. Open Google Photos and find the screenshot.
3. Slip on the Google Lens icon (bottom of the screen or in the “More” menu).
4. Select the area with QR-code - the system automatically recognizes it.

The advantage of this method is that it's 100% static, without flickering or distortion, but keep in mind:

• 📌 Google Lens may not recognize low-resolution codes (less than the 300x300 pixel).
• 📌 On some models (for example, Black Shark 5), Google Lens is disabled by default – you need to install it from Google Play.

If QR-The code on the screen is too small, zoom in with a pinch gesture before you create a screenshot, which will increase the chances of successful recognition.

Method 3: Screen Mirror Mode (for MIUI 14+)

MIUI 14 introduced a hidden screen mirror feature that allows you to “fix” an image from a screen for scanning, a technique that is particularly useful for codes on animated banners or applications with dynamic content (such as Mi Home).

Instructions:

1. Open Settings → Special features → Utilities.
2. Activate the Screen Mirror option (may be called Screen Fixing).
3. Go back to the screen with QR-code and make a triple tap gesture with three fingers.
4. The screen will freeze, after which it can be scanned in a standard way.

Limitations of the method:

⚠️ Note: On some devices, after using Screen Mirror, the swipe up gesture for the home may temporarily turn off.To return it, restart the phone.

Method 4: Xiaomi’s Scanner app (for older models)

If you have a device on MIUI 11 or older (like the Redmi Note 9 or Mi 9T), a standard scanner may not be able to handle the code on the screen, and Xiaomi’s official Scanner app, which is often preinstalled but hidden in the Tools folder, will help.
