How to scan on Xiaomi QR-code: full guide

Smartphones have long been universal tools to replace wallets, keys, and even printed books. In the Xiaomi, Redmi, and POCO ecosystem, interaction with the digital world often occurs through two-dimensional barcodes. Users are faced with the need to read information from a product’s packaging, connect to a friend’s Wi-Fi network, or log in to a messenger’s web version every day. However, despite the ubiquity of technology, not all gadget owners know where to look for an embedded scanner.

Unlike some competitors, Chinese manufacturers often hide this feature deep in system applications or, conversely, take it to the screen locker, which can confuse the beginner. QR-Xiaomi codes do not require the installation of third-party software, since the necessary modules are built into the shell. MIUI Understanding the logic of system utilities will save you time and avoid installing dubious programs from the Play Market store.

In this guide, we will take a look at all the available data-reading techniques. We will look at the standard Scanner app, the system camera capabilities, desktop widgets, and even the hidden features of Google Lens. You will learn how to set up automatic link recognition and what to do if the camera refuses to focus on the image. It is important to note that, starting with Android 9, the feature is built directly into the camera drivers of most devices, allowing you to read code without opening additional programs.

Use of the built-in Scanner application

The most functional tool for working with code is a regular application, which is pre-installed on all devices of the brand, usually called a "Scanner" or "Scanner" and an icon in the form of a lens or barcode. It is not just a link reader, but a full-fledged multitool that can recognize goods, documents and even translate text in real time.

When you run the program, you'll see a viewfinder interface with multiple modes at the bottom of the screen, and the default mode is Code, which automatically determines the type of encryption and suggests the appropriate action: open a link, add a contact or call a number. To successfully hover, just hold the phone parallel to the surface so that the image is clear.

• 📱 Code mode – designed for reading QR-Data Matrix and Standard Barcodes of Goods.
• 🛒 Mode "Product" - allows you to point the camera at the label in the store and see current offers on the Internet.
• 📄 Document mode – takes a photo of a document, aligns perspective and improves readability of the text.

If the standard application launch is not through an icon, try searching the system. Type the word "Scanner" in the desktop search bar, and the system will find the desired shortcut, which is especially true if you accidentally hid the application in a folder or renamed it.

⚠️ Warning: When scanning codes of unknown origin from suspicious sources, the security system MIUI Never follow a link unless you are sure of its safety, even if the antivirus is silent.

For users who often work with documents, text recognition mode will be useful: the camera not only takes a picture of the page, but also converts the image into editable text, which is convenient for quickly copying large amounts of information from paper media in digital form.

💡

Set up the “Save History” mode in the Scanner app to always have access to previously scanned codes, even if you accidentally closed the app immediately after reading.

Quick scan through the Camera app

Many users don’t realize that they don’t need to search for a separate app at all. Modern versions of the HyperOS shell and recent MIUI updates have integrated Google Lens, or its own recognition algorithm, directly into the main camera viewfinder, allowing you to instantly respond to codes without making unnecessary swipes across the screen.

To activate this feature, you need to open the standard Camera app. In some versions of the firmware, just point the lens at the code, and the system itself will suggest clicking on the link with a pop-up. If this does not happen, check the settings. In the upper corner of the screen, there is often an icon for "AI" or "Google Lens" (a colored dot lens) that you need to activate.

The algorithm is simple: you hover the camera, the system analyzes the image in real time, and when it's recognized successfully, an interactive button or link appears on the screen, which is faster than launching an individual application, because the processing process is triggered at the system level when the camera is activated.

• 🔍 Google Lens icon – activates intelligent search and code scanner inside the camera.
• ⚡ Function AI-Cameras – automatically determines the scene and suggests actions, including reading QR.
• 🔗 Pop-up notification – appears directly on top of the viewfinder when an active link is detected.

It is worth noting that integration with Google Lens requires Google services, which is relevant for global firmware versions. On Chinese versions of smartphones without flashing can use Xiaomi’s own algorithm, which works similarly, but with an interface in English or Chinese.

If automatic recognition doesn't work, try taking a photo and then opening the gallery. Modern versions of MIUI have a Smart Gallery feature that analyzes the contents of the image. By clicking on the image with the code, you can often see the "Recognise QR" button or a similar option in the action menu.

Setting up the scanner widget on the desktop

For those who use a smartphone to constantly interact with codes (for example, couriers or warehouse workers), the optimal solution is to take the function to the main screen. The Scanner widget provides instant access to the function in one tap, bypassing folders and application menus.

Adding a widget takes a few seconds. You need to pinch an empty space on your desktop or pinch a two-finger to go into editing mode. In the menu that appears, select "Widgets." In the list, find the "Tools" or "Scanner" section.

There are several ways to display the widget. This can be a simple icon, a circular switch, or a widget with a history of recent scans. Choose the one that fits better into your interface design. After selecting the size, drag the item to the free space of the screen.

The widget is especially convenient when the phone screen is locked. Some design themes allow you to configure the scanner to start even from the lock screen if you add the appropriate shortcut to the notification area or to the Always On Display screen.

Remember that widgets consume a small amount of RAM, although in the case of a scanner, this effect is minimal, since the process does not go in the background constantly. It only activates when you press.

Scan through the control panel and side panel

The MIUI shell is famous for its functionality, and one of the useful features is the Control Center. Depending on the Android version and regional setting, the scanner switch can be in the notification curtain.

To check, lower the curtain from top to bottom. If you can't see the scanner icon, try spreading the curtain down from the center to open the full list of switches. In some firmware, this element is called "Scan" and has a characteristic icon.

Another quick access option is the sidebar, which is a vertical bar that appears when you swipe from the edge of the screen, and you can add a scanner shortcut to it, open the sidebar, click on the settings (cogs), and in the Add Apps section, find the Scanner.

• 📲 Control Center – Quick access through notification curtain.
• 🧭 Sidebar – Swipe call from the edge of the screen in any application.
• 🖱️ Floating window – the ability to scan code on top of other open programs.

Using the sidebar is particularly effective in multitasking, for example, if you're texting in a messenger and the person sent the code image, you don't have to leave the chat room. Just call the sidebar, run the scanner in a floating window, and point the camera at the second device or printout.

⚠️ Note: If you add a scanner to the sidebar, make sure the app has permission to work on top of other windows.Without this right, the floating window may not start or be invisible.

Setting up access through the control panel may require editing the switch grid. Often this switch is hidden by default so as not to clutter the interface, so it needs to be manually dragged to the active zone via the editing menu (pencil icon).

Using Google Lens and Google Photos

Even if standard methods are not available or seem inconvenient for some reason, Google services work on any certified Xiaomi smartphone. Google Lens is a powerful computer vision tool that is often built into the Google search bar or Google Photos app.

In the Google app (G icon), to the right of the search bar, there's a little camera icon, and you click on it, you launch a lens. It works like a camera, but it focuses on finding information. Point to the code, and the system will suggest clicking on a link or show product information.

The alternative is through the gallery. If you've already taken a photo of the code, open the image in the Google Photos app. At the bottom of the screen, a search or Lens button often appears, and clicking on it will trigger an analysis of the image, and the code will be recognized automatically.

The advantage of using the Google ecosystem is cross-platform: The crawl history is saved in your account, and you can access the link later from any other device, whether it's a computer or tablet.

In addition, Google Lens is able not only to read a link, but also translate text on the code in real time, if it is, for example, a restaurant menu in a foreign language, presented in the form of a QR. This makes it an indispensable tool for travelers.

The Solution: Why the Camera Can't See the Code

Despite the advanced technology, there are times when Xiaomi’s phone doesn’t recognize it. QR-This could be due to software failures, contamination or security settings. First, check the cleanliness of the lens.

Fat spots or dust on the camera lens blur the image, and the algorithm can't read the contrasting pattern of the code. Wipe the camera with a soft cloth. Also, there may be insufficient lighting or glare on the glossy surface of the code.

If everything is physically clean, check the app's permissions. Go to Settings → Apps → All apps → Scanner (or Camera) → Permissions. Make sure that access to the camera is allowed. Sometimes, after a system update, the settings are reset and access is blocked.

• 💧 Wipe the camera lens with a soft cloth from fat marks.
• 💡 Increase the brightness of the screen or add external lighting.
• 📏 Change the distance to the code: move away or zoom in to focus the phone.

In rare cases, cleaning the app cache helps. In the same app settings menu, find Memory and click Clear Cache. This won't delete your personal data, but it will reset temporary files that may have been corrupted.

💡

In 90% of cases, the problem is solved by simply rubbing the lens or changing the angle of the phone relative to the code to eliminate glare.

Also, consider that some codes can be corrupted or printed in low resolution. If the camera is focusing but not reading data, try using zoom (approximation) with your fingers to take up most of the viewfinder screen.
