Modern smartphones have long been universal tools for interacting with the digital world, and Xiaomi devices are no exception. Owners of popular Redmi Note models often face the need to quickly read the information encoded in a graphic image, whether it is a link to Wi-Fi, restaurant menus or authorization data. However, the standard interface of the MIUI shell or HyperOS can hide some functions, making the process unobvious to beginners.
In this article, we will take a closer look at all the scanning methods available on the system, as well as effective third-party solutions, learn how to activate hidden camera features, where to find a separate scanner app, and what nuances exist when working with different versions of the Android operating system on Xiaomi devices.
Understanding these mechanisms will save you time and avoid installing unnecessary software that often overloads your device with ads.We’ll go from basic settings to advanced security features, ensuring maximum efficiency of your gadget.
Built-in MIUI and HyperOS camera capabilities
The first place that Xiaomi owners should look is the standard Camera app, and the company's engineers have implemented code recognition directly into the viewfinder, making it as fast as possible. You don't have to look for a separate program or open a browser, you just have to point the lens.
However, this feature is not always active by default or may not work properly due to a setup failure. To check and activate the mode, you need to go to the settings menu of the camera itself, usually a three-strip icon or a gear in the corner of the screen, and you should find the item responsible for code recognition and make sure that the switch is green.
⚠️ Note: Some global firmware versions may call the feature “Google Lens” or “Lens”, which is similar to a native scanner, but requires a connection to Google services.
If a standard camera doesn’t see the codes, it may be the access rights or version conflict of the app, so clear the camera cache through the system settings or update the app through the Google Play store. Also make sure the lens is clean, as greasy spots often interfere with focusing on the fine details of the image.
- 📱 Open the Camera app on the home screen.
- ⚙️ Click on the settings menu (three bars or gears).
- 🔍 Find the "Scanner" or "Code Recognition" section».
- ✅ Activate the switch if it is turned off.
After turning on this option, pointing the camera at QR-The code will automatically trigger a pop-up notification with a link or action, which is the fastest way to do so without requiring additional manipulation of the interface.
Use of the Mi Scanner app
In the Xiaomi ecosystem, there is a separate system application called the Scanner (or Mi Scanner), which is often ignored by users, and is more powerful than a simple in-camera mode, since it can not only read links, but also recognize products, translate text and scan documents.
You can find it in the Tools folder on your desktop or through an application search. The interface is divided into tabs, allowing you to switch between QR scanning modes, product barcodes and documents, which is especially convenient if you need to scan an item in a store and see its price immediately in online stores.
One of the key features of the Mi Scanner is that you can recognize the codes from the gallery, and if you're sent a picture of the code in the messenger, you don't have to take a screenshot and look for where to open it, but you just have to choose the Image or Gallery mode in the app, and the system will analyze the picture itself.
Why is Mi Scanner better than third-party counterparts?
For users who value functionality, this application is mandatory to install if it has been removed and can be returned via system settings or downloaded from the official GetApps app store.
Integration of Google Lens and Google Lens
Most modern Redmi Note smartphones running Android pre-installed Google services that offer an alternative and often more accurate way of scanning. Google Lens technology is built into many system components, including the search bar and the Google Photos app.
To take advantage of this method, you just open the Google search widget on your desktop and click on the camera icon, and it will trigger an augmented reality mode that instantly recognizes the code, and the advantage of this method is that Google's powerful recognition algorithms can even cope with corrupted or poorly printed codes.
Google Lens can also translate text in real time, recognize dog breeds, plants and landmarks, making it a versatile tool that goes far beyond just reading links, and may require an internet connection to activate the feature, as image processing often takes place on the company’s servers.
- 🌐 Click on the Google search bar widget.
- 📷 Tap the camera icon (Google Lens) on the right.
- 🎯 Point the camera at the object or select a photo from the gallery.
- 🚀 Click on a pop-up link or action.
If the widget is not on the screen, you can add it by long-clicking on the free desktop space and selecting the "Widgets" item, where you need to find "Google" and drag the search bar to the screen.
Scanning from gallery and browser
Often, there are situations where the code is already stored on the device as an image, and it is inconvenient or impossible to point the camera at the screen of another device. In such cases, image analysis features built into the MIUI shell come to the rescue. When you open the picture in the standard gallery, you can see the “More” button or the scanner icon in the bottom menu.
When you press this button, the system will analyze the image and, if it detects it, QR-This works similarly in Mi Browser: if you see code on a site, you can take a screenshot and then use the image search function or the built-in scanner in the address bar.
For those who work with documents often, it is useful to know that many file managers, including Xiaomi’s standard Explorer, are also able to view images and may have a built-in recognition feature, but this process works most consistently through their home gallery.
⚠️ Warning: When scanning codes from unknown sources (such as screenshots from strangers), always check the link address before clicking to avoid phishing sites.
This feature is especially useful when setting up a smart home, when instructions come in the form of pictures, or when receiving promo codes in instant messengers. You do not need to rewrite long combinations of characters manually.
Third-party applications for extended functions
Despite the rich functionality of Xiaomi’s standard tools, there are sometimes specific tasks that require specialized software. There are many applications in the Google Play store that offer advanced features, such as cloud-scan history, creating your own codes in complex shapes or batch scanning.
One popular solution is Gamma Play's QR & Barcode Scanner, or Kaspersky's equivalents, which emphasize security, which checks for a link for viruses and fraudulent schemes before opening it in a browser, which is critical when scanning codes in public places.
There are also code generation apps if you need to create your own. QR-It's a business card code or Wi-Fi network code that allows you to customize the color, the logo in the center and the format of the data. Xiaomi's standard tools are often focused on reading, not creating.
When choosing a third-party app, pay attention to the permissions it requests. the scanner doesn't need access to your contacts or microphone to work. Avoid apps that rank low or have a lot of negative ad reviews.
☑️ Criteria for selecting a third-party scanner
Problems and their solution in scanning
Even the powerful Redmi Note series smartphones sometimes have difficulty recognizing, most often the problem is insufficient lighting or hand shaking, the camera does not have time to focus, and the code remains unread, in such cases it is worth turning on the flash or stabilizing the elbows.
Another common problem is that the code is corrupted or too small, so if a standard camera can't see the code, try zooming in or pulling away to capture more context, and rubbing the lens with a soft cloth also helps.
In rare cases, you may need to reset your camera app settings. Go to Settings → Apps → All Apps → Camera and select Clear Data. This will return your viewfinder settings to factory values.
| Problem. | Possible cause | Decision |
|---|---|---|
| The camera is not focusing. | Dirty lens or case | Wipe the camera, take off the case. |
| Link won't open | No internet or blockage | Check the connection, use VPN |
| The black and white code is not readable. | Low contrast or damage | Use a Google Lens or Third-Party App |
| App flies out | Lack of RAM | Close the background applications, restart the phone |
If neither of these methods works, it's possible that the code itself is misgenerated or misprinted, and you should ask for the information in text form.
Safety in use QR-code
Using fast-response technology carries not only convenience, but also risks. Attackers can create fake codes that redirect users to phishing sites that copy bank or social media interfaces. On Xiaomi devices, built-in security can warn of danger, but not always.
A critical rule is to check the domain name of a site before entering any personal data. If you are scanned and you are on a page that requires a password or card number, carefully check the browser address bar. Often, scammers use similar domains, replacing a single letter.
Also beware of codes that suggest installing an app bypassing Google Play (.apk files). On Android, this is the main way malware is distributed. MIUI has a built-in virus scanner, but it can skip new threats.
⚠️ Warning: Never scan codes pasted over original payment codes in public places (parking, terminals) – this is a frequent method of stealing card data.
For maximum security, it is recommended to install an antivirus application with real-time protection and regularly update Xiaomi’s security system through the Security app.
