Xiaomi’s modern smartphones, including the popular Redmi lineup, have become universal tools for interacting with the digital world. QR-Users often face a situation where they need to quickly click on a link, connect to Wi-Fi or get a discount in the store, but do not know where to find the desired option in the interface.
The built-in MIUI and HyperOS shell algorithms allow you to recognize graphic tags instantly using a regular camera or special system utilities. However, depending on the firmware version and device model, the location of settings may vary. In this article, we will discuss in detail all the available scanning methods so that you can choose the most convenient one for yourself.
Use of the regular Camera application
The fastest and most obvious way for Xiaomi and Redmi smartphone owners to use the standard Camera app is to use Google Lens and its own code analyzer directly into the viewfinder interface, so you don't have to search for individual programs, you just have to start shooting.
To activate the function, you need to make sure that the camera settings are on recognition mode. Usually, the default system suggests scanning the code when it hits focus, giving a pop-up notification. If this does not happen, you should check the top toolbar or settings for photo mode.
It's worth noting that the quality of the lenses and the speed of the autofocus affect the read speed. On the budget models of the Redmi Note or Redmi A series, the process can take a fraction of a second longer than on flagships, the main thing is to keep the phone still and ensure good lighting of the object.
- 📸 Open the Camera app and point the lens to the code.
- ⚙️ Check for the “Google Lens” or “Scanner” icon at the top of the screen.
- 🔗 Wait for a pop-up with a link or action to appear.
- 👆 Click on the notification to click on the link or save the contact.
⚠️ Attention: If the camera is focusing but doesn't offer action, you may have the Document Scanner or Google Lens feature disabled in the settings.
Sometimes users are faced with the fact that the camera sees the code, but does not read it, this can be due to image damage or low resolution of the matrix, in such cases, it is recommended to zoom in on the phone or wipe the lens.
Scanner through the control center and desktop
Shell MIUI It's famous for its functionality, offering a variety of ways to access commonly used tools, in addition to the camera, the built-in scanner. QR-The codes are available through the Control Center and desktop widgets, which is especially convenient when the phone screen is turned off or occupied by another application.
To add a scanner to the curtain, you unlock the screen, swipe down to open the control center, and click on the edit icon (usually three dots or a pencil). In the list of available toggles, find the "Scanner" and drag it to the active zone. Now access to the function is done in one touch.
Alternatively, using the Tools widget on the desktop, which often has a “Scanner” shortcut in Xiaomi’s system application folder that triggers a separate window to hover over the code, saves battery power by not activating the heavy image processing algorithms of the main camera.
It is important to understand the difference between a conventional scan and a deep analysis, and Storka often uses a simplified algorithm that works faster but may not recognize the complex or corrupted codes that a full camera can handle.
Application "Scanner" in system utilities
Deep in the system folders of Redmi smartphones, a separate app called the Scanner is a more advanced version of the feature built into the camera, and has additional features such as text recognition (OCR) and translation.
Launching this app gives you access to your scan history, which is extremely useful if you accidentally close a link or forget to copy the Wi-Fi number of your network. Unlike quick launch through the camera, here the interface is designed to work with codes of various formats, including barcodes of goods.
The app’s functionality allows not only to open links, but also to add contacts to a phone book, connect to wireless networks, and even pay for purchases if the code contains payment data, a universal tool that every user of the ecosystem should have at hand.
- 📂 Find the Tools folder on your desktop.
- 🔍 Launch the application with the Scanner icon (green square with a beam).
- 📜 Use the lower menu to switch modes (code, document, translation).
- 💾 View the action history in the recent tab».
⚠️ Note: When scanning codes of unknown origin, always check URL-Attackers can create copies of codes that lead to phishing sites.
One of the hidden features of this app is the Documents mode, which allows you to scan text from paper and convert it to digital format, which makes the application useful not only for the users of the software. QR-tags, but also for working with paper carriers.
Customization and calibration for different models
The variety of Xiaomi and Redmi models implies hardware differences: Budget devices like the Redmi 13C or Redmi Go may have less-performing image processors, requiring the right setup for the scanner to work smoothly.
First of all, we recommend updating the Camera and Scanner apps through the GetApps store or Google Play. Developers regularly release patches that improve compatibility with new code formats and correct focus errors on specific models.
Also worth paying attention to the viewfinder resolution. In some cases, switching to Pro mode or changing the aspect ratio can improve the clarity of the picture, which will positively affect the recognition speed. Remember to wipe the lens regularly, as greasy traces greatly interfere with autofocus.
☑️ Checklist for camera preparation
If your device has custom firmware or a global version with regional restrictions, some features of Google Lens may not be available, in which case the MIUI system scanner becomes the only regular option.
Solving recognition problems
Despite the advanced technology, users sometimes face situations where the Xiaomi phone refuses to scan the code.This can be caused by a software failure, lens contamination or the specifics of the image itself.
A common problem is insufficient lighting or glare on the surface of the code. Laser printing on glossy paper can create reflections that the camera perceives as part of the code, making it unreadable. Try changing the angle of the phone relative to the plane.
Another important aspect is software conflicts. If you installed a third-party camera app or a scanner from the Play Market, the system may try to use them by default, ignoring system settings. Check the default application settings in the Apps section.
| Problem. | Possible cause | Decision |
|---|---|---|
| The camera is not focusing. | Lens contamination or macro-mode | Wipe the camera, move the phone. |
| Code is read, but the action is not performed | Format error or broken link | Check the integrity of the code, update the software |
| No pop-up. | Google Lens is disabled | Enable in camera settings or update services |
| The scanner is slow. | Lack of RAM | Close background applications, clear cache |
What to do if the code is damaged?
In some cases, a banal device reboot helps, which clears temporary files and restarts camera services, which often solves problems with the recognition module freeze.
Security in Code Scanning
Use of the QR-Because code can contain a link to any resource, attackers are actively using this channel to distribute malware or steal data.
Android System and Shell MIUI They have built-in security mechanisms that warn you of going to suspicious sites, but the human factor remains a weak link. Never enter passwords or card information on pages that are opened through an unknown location. QR-code, without prior address verification.
It is recommended to establish a habit of looking at URL-If a domain looks strange or has a misprint in a well-known brand name, you better not go. Also beware of codes that offer "win" or require urgent action.
💡
Use the “Security” feature in your phone settings to check URL-Xiaomi Antivirus often tags known phishing resources before opening a page.
For corporate users, there is a possibility to configure a security policy that prohibits scanning codes from unverified sources, but at home the responsibility lies with the user himself.>
Alternative apps from Google Play
If Xiaomi’s regular tools don’t meet your needs for some reason, Google Play offers hundreds of alternatives. Third-party developers create applications with advanced functionality: batch scanning, creating their own codes, history in the cloud and no advertising.
One popular solution is Gamma Play’s QR & Barcode Scanner or Kaspersky’s, which often works faster on older phone models because it uses lighter processing algorithms without overloading the system with unnecessary effects.
When choosing third-party software, pay attention to the permissions the app requests. The scanner doesn't need access to your contacts, microphone, or geolocation to easily work with the camera. Excess access rights are a wake-up call.
- 📲 Download a proven high-rated app.
- 🛡️ Check the requested permissions before installation.
- ⚙️ Configure the interface for yourself (themes, font size).
- 🗑️ Regularly clear the scan history in the app.
💡
Xiaomi’s regular funds in 95% of cases fully cover the needs of the average user, making the installation of additional software redundant.
However, for professional use, such as in logistics or retail, specialized software can provide the necessary batch processing and data export functionality to Excel.
