How to scan. QR-Xiaomi phone code directly from the screen: all ways

You're trying to scan. QR-The code from the screen of another device — phone, tablet or computer — but Xiaomi’s camera stubbornly refuses to recognize it?The problem is familiar to many: the standard camera app often ignores codes on displays due to glare, low contrast or protection against counterfeiting. In this article, we will discuss 5 working ways to bypass the limitations and successfully calculate the results of the study. QR Even from the screen, including hidden features MIUI and third-party instruments.

Features of smartphones Xiaomi, Redmi and POCO — built-in QR-We've been testing it at the system level, but it's not always optimized for reflected light. MIUI 12-15 (including global and Chinese firmware) and found out which ones work consistently on models from Redmi Note 10 to Xiaomi 14 Ultra.

Why Xiaomi is not scanning QR-Screen code: 3 main reasons

Before we get to the solution, we'll see why a standard MIUI scanner might not see the code on the display, and the reasons are technical and software.

• 🔦 Reflections and glare: Smartphone screens are covered with protective glass that scatters light. Xiaomi's camera captures those glares as noise masking QR-code.
• 📱 Low refresh rate: On 60Hz displays, the code can flicker for the camera, especially if it is animated (e.g., in payment systems).
• 🛡️ Fraud protection, some banking and payment services QR (For example, in SberBank Online or Tinkoff, dynamic elements are deliberately blocked by scanners to prevent screenshot attacks.

Interesting fact: on Xiaomi with AMOLED-screens (for example, Xiaomi 13 Pro or Redmi) K60) This is a problem that's less common because of the high contrast of the display. IPS-Matrices (e.g. Redmi Note 12) have to use workarounds.

⚠️ Attention: If QR-The code is related to a payment system (for example, to transfer money), never scan it from someone else's screen.

Method 1: Built-in scanner in the Camera app (with settings)

The most obvious method is to use a standard Xiaomi camera, but with the right settings. Many users are unaware that MIUI has hidden options to improve QR recognition.

How to turn on:

1. Open the Camera app**.
2. Touch the icon "More"** (three horizontal lines or gear depending on the model).
3. Select the QR scanner mode (or QR Code in English firmware).
4. Hover the camera over the code on the screen and hold the phone at a distance of 15-20 cm.

If the code is not recognized:

• 🔄 Try changing the angle of the phone to reduce glare.
• 🌓 Reduce the brightness of the screen of the device you are scanning from (sometimes helps to put it in Dark Theme mode).
• 📸 Turn on the Xiaomi camera option HDR (High dynamic range – this improves contrast.

Make sure the code is not blurred on the screen | Turn off automatic brightness on the scanned device | Check that the Xiaomi camera is free of dirt or scratches | Try scanning in a well-lit room-->

On Xiaomi models with a Snapdragon 8 Gen 2 processor (such as the Xiaomi 13T), the built-in scanner supports the Smart Recognition feature, which automatically corrects distortion from the screen. To activate it, go to the camera settings → Additional → Improve QR.

Method 2: Screenshot + edit (for static QR)

If QR-It's not dynamic, like a link to a website or Wi-Fi, and you can take a screenshot, edit it, and then scan it, and it works 90 percent of the time when the problem is glare.

Instructions:

1. Take a screenshot of the screen with QR-code (for example, press Volume down) + Nutrition).
2. Open the screenshot in the Gallery app**.
3. Click “Edit”** and select the Trimming tool.
4. Cut the image so that QR-The code took at least 70% of the frame.
5. Save and open the built-in Xiaomi scanner (or use Google Lens).

Why it works: Pruning removes glare and noise, and zooming in improves readability for the recognition algorithm, and the method is not suitable for dynamic QRs (for example, in VK Pay or YuMoney).

💡

If QR-code on your computer, try to take a screenshot of not the entire screen, but only the area with the code (in Windows: Win) + Shift + S. Then transfer the file to Xiaomi via Mi Drop or Telegram and scan it from your phone.

Method 3: Third-party scanning applications

If embedded tools MIUI They don't, they'll come to the rescue with specialized applications. 7 Popular scanners and selected the top-3, which work best with QR-screencode:

How to use:

1. Install one of the applications (links to Google Play).
2. Open the scanner and point the camera at QR-code.
3. If the code is not recognized, try:

• 🔍 Enable the option of Improved Recognition in the application settings (if any).
• 📱 Switch the camera to macro mode (if supported).
• 💡 Use a flashlight to light up (sometimes helps with a dim screen).

⚠️ Attention: Apps like QR Scanner from unknown developers can collect data about the codes being scanned. Before installing, check reviews and permissions on Google Play.

Method 4: Google Lens is a universal tool

Google Lens is built into most Xiaomi Android smartphones and often does so where the standard MIUI scanner is powerless, with the advantage of machine learning algorithms that better filter noise and glare.

How to Scan QR with Google Lens:

1. Open the Google app (or Google Photos).
2. Click on the Lens icon** (camera icon in the search box).
3. Put the camera on QR-If the code is in the screenshot, select Import from the gallery.
4. Wait for recognition (can take up to 5 seconds).

Google Lens successfully reads up to 85% QR-codes from the screen, including those that are not recognized by the standard Xiaomi camera, is especially effective for codes with low contrast (for example, white code on a light background).

Method 5: Manual decoding of QR (for advanced)

If all automatic methods fail, you can try to manually decode them. QR-It takes a little bit more effort, but it works even with corrupted or blurred code.

Instructions:

1. Take a screenshot. QR-code (or take a photo of it).
2. Go to the ZXing Decoder website (or similar).
3. Upload the code image.
4. The service will show decrypted data (link, text, etc.).

Advantages of the method:

• 🔧 Works with corrupted codes (up to 30% of data loss).
• 🌐 Supports all formats QR, including rare ones (e.g. Micro) QR).
• 🔒 Secure for payment codes (the service does not save uploaded images).

Disadvantages: Not suitable for dynamic codes (like WhatsApp Web) as they are updated every 30 to 60 seconds.

💡

Manual decoding is the only way to read QR-code if it is partially erased or covered (for example, by the company logo).

Frequent Mistakes and How to Avoid Them

Even with the right tools, users often make mistakes that interfere with scanning.

• 📵 Too close/far away. The optimal distance is 15-25 cm. If you hold the phone close, the code may be out of focus.
• 🌡️ Incorrect angle of inclination. It is better to keep the phone perpendicular to the screen to avoid distortion.
• 🔋 Battery discharged on some Xiaomi models (e.g., Xiaomi, POCO X3) When the charge is low (15%), the camera automatically lowers the resolution, which impairs recognition.
• 📶 Bad lighting. In the dark, the camera zooms in. ISO, That adds noise. Use a flashlight or an external light source.

A simple test: If your Xiaomi isn’t scanning the QR from the screen, try scanning the code from paper first, and if that doesn’t work, the problem is with the camera settings or firmware.
