How to scan. QR-Xiaomi Redmi 9 code: all methods from standard to hidden

Why the QR scan on Redmi 9 raises questions

QR-Codes have long been an integral part of everyday life, from paying for purchases to logging into Wi-Fi networks. Xiaomi Redmi 9 owners often face confusion when trying to scan the code, either because of the non-obvious location of the feature in the app. MIUI, It's because of the camera features of a budget smartphone, and unlike flagship models, where the scanner is integrated into quick settings, the path to it can be confusing here.

The problem is compounded by the fact that Redmi 9 comes with different firmware versions (depending on the region), and some MIUI 12/13 updates port or hide standard tools. For example, in the European version, the scanner may not be on the camera menu, whereas in the global version it is available by default. This article covers all possible scenarios, from basic to alternative methods, including solutions for cases when the camera refuses to focus on the code.

We tested each method on Redmi 9 with MIUI 12.5.7 and MIUI 13.0.4 firmware, and also took into account the nuances of working with low contrast codes (for example, on TV screens) or damaged QR. If you have previously tried unsuccessfully to scan the code through a standard camera, here you will find workarounds.

Method 1: Built-in scanner in the Camera app

The most obvious, but not always the most effective, method is to use the standard Camera app, and in theory, you just have to point your lens at the camera. QR-The code, and the smartphone must automatically recognize it and suggest an action (open a link, connect to Wi-Fi, etc.). However, in practice, users of Redmi 9 often find that the function simply does not work.

To activate the scanner:

• 📷 Open the Camera app (icon on the home screen or menu).
• 🔍 Go to Additional (or More in English) mode – usually marked with three dots or stripes.
• 🤖 Select Scanner item QR (or QR If you don't have one, read the next section.
• 🎯 Point the camera at the code so that it fits fully into the frame: 10-20 cm for small codes and up to 50 cm for large codes.

If you don't have QR scanner on the menu, it means that the function is disabled in the system settings.

1. Go to Settings → Applications → Application Management.
2. Find the camera and open its settings.
3. Slip on Permissions and make sure that the Camera permission is enabled.
4. Go back and select Application Rights. → Special access → Recognition QR-codes (if there is a paragraph).

Important: The Redmi 9 scanner is not good at handling codes on low-brightness screens or in direct sunlight. If the code doesn't recognize, try changing the phone's angle or turning on a flash (even during the day).

Method 2: Quick scan through the notification panel

MIUI 12.5 and later has the ability to scan QR directly from the notification panel without opening the camera, which is faster but requires pre-tuning. Unfortunately, some versions of Redmi 9 (especially those with lighter firmware for weaker regions) may not have this feature.

How to turn on and use:

• 🔽 Swipe down from the top edge of the screen to open the notification bar.
• 🔍 Scroll down to the end and tap the icon. ⚙️ Edit (or Edit).
• 🤖 Find the scanner widget in the list QR (a dot box icon and drag it to the active area.
• 📱 Now, when swiping down, you will see the scanner icon - tap on it and point the camera at the code.

If the widget is not listed, it means your version of MIUI does not support it.The alternative is to use Google Lens (see next section), which is integrated into Google's search bar.

Method 3: Google Lens is a universal tool for all codes

Google Lens is a powerful tool from Google that can not only recognize QR-It's more stable than the built-in scanner on Redmi 9, especially with low-quality codes, and the main advantage is that you don't need to install additional applications, because Lens is built into Google services.

How to Scan Through Google Lens:

1. Hold the Google icon (search bar) on the home screen or in the app menu.
2. In the menu that appears, select Lens (the icon with a dot in a circle).
3. Put the camera on QR-Lens automatically recognizes it and offers an action (for example, open a link).

If there is no Lens icon, update the Google app through the Play Market or install it separately.

• 📷 Open Google Photos and select any image.
• 🔍 Slip on the Lens icon in the bottom panel.
• 📲 Put the camera on QR-real-time code.

Google Lens recognizes QR-codes even on curved surfaces (e.g. bottles) or with partial damage, whereas a standard scanner MIUI They often refuse to work in such conditions.

💡

If Google Lens doesn't recognize the code, try taking a photo of the code and uploading it to Lens through Google Photos, which increases the chances of a successful crawl by 30%.

Method 4: Third-party applications for complex cases

If built-in methods don’t work (for example, due to outdated firmware or hardware limitations of the Redmi 9 camera), third-party scanners come to the rescue. They offer additional features: scan history, manual focus adjustment, support for corrupted codes, and even QR generation.

Top.-3 Proven applications for Redmi 9:

How to choose the appropriate application:

• 🛡️ If you scan codes for payment or authorization, use Kaspersky. QR Scanner (checks links to fraud).
• 📱 For everyday tasks (Wi-Fi, links) is suitable QR & Barcode Scanner.
• 🔧 If you want maximum compatibility with corrupted codes – ZXing Team.

Method 5: Hidden feature in Quick Settings (MIUI 13+)

MIUI 13 and later has a hidden ability to scan QR directly from the control center (quick settings), which is not available by default, but can be activated through developer settings or special gestures.

How to turn on:

1. Go to Settings → About Phone and tap 7 times on the MIUI version to activate the Developer Mode.
2. Back to Settings → Additionally. → For developers.
3. Find the option to Enable the QR scanner in the notification bar (or Quick Settings QR Scanner) and activate it.
4. Now, when swiping down twice (full panel opening), you will see the scanner icon next to the flashlight.

This method works faster than a standard camera, as it does not require a separate application to run. However, on Redmi 9 with 3/32 GB of memory, you can experience a slowdown on the first run due to a lack of RAM.

💡

The scanner in quick settings consumes 20% less battery power than running a full-fledged Camera app, as it does not activate all the camera modules.

The solution to the problem: why the Redmi 9 does not scan QR-code

Even with the right settings, Redmi 9 may not recognize the device. QR-The causes fall into three categories: hardware (camera problems), software (firmware failures) and external (bad lighting, damaged code.

Hardware problems:

• 📵 Contaminated lens – wipe the camera with a soft cloth (do not use alcohol!).
• 🔍 Disfocus – Try manually adjusting focus by touching the screen in the code area.
• 💥 Camera damage – if the codes are not recognized even in other applications, check the camera in photo mode (if there is also blurred – a malfunction of the module).

Programmatic failures:

• 🔄 Outdated firmware - update MIUI through settings → Updating the system.
• 🚫 Application conflict – disable other programs that use the camera (for example, messengers with scanning function).
• 📱 Reset camera settings - go to Settings → Annexes → Camera. → Warehouse → Clear the data.

External factors:

• ☀️ Bright lights/glare – cover the code screen with your hand to remove reflections.
• 🖼️ Low code contrast – increase the brightness of the screen of the device on which it is displayed QR.
• 📏 Wrong distance – it is optimal to keep the phone at a distance of 15-30 cm from the code.

💡

If the code is printed on glossy paper (for example, in a magazine), try to photograph it at a 45° angle - this will remove glare and improve recognition.

⚠️ Warning: If after all the manipulations, the scanner still doesn't work, check if the camera module is disabled in the security settings. Some antiviruses (for example, Avast) block access to the camera for all applications except standard ones.
