Modern smartphones of Xiaomi have become universal tools for interaction with the world around us. QR-Codes are key. You no longer have to search for special apps in the Play Market store, because the basic functionality of the system already includes everything you need. Users often look for quick ways to log in to WhatsApp Web, connect to Wi-Fi or pay for purchases, and the right approach to scanning saves time.
The MIUI shell interface and the new HyperOS offer several ways to do this, each with its own specifics: some work instantly, others require pre-tuning, but all provide high accuracy recognition. In this article, we will discuss in detail how to activate the desired functions and avoid typical errors when reading encrypted images.
Understanding how to count QR-Xiaomi code is needed by every smartphone owner, because it makes it easier to access restaurant menus, websites and payment systems. Standard camera often recognizes the link automatically, but in some cases requires user intervention or the use of specialized scanners. We will consider all the nuances of working with graphic codes on devices of different generations.
Using a standard camera for scanning
The most obvious and quick way to activate the scanner is to run the standard Camera app. On most modern Xiaomi, Redmi and Poco models with the current firmware version, the recognition function is built in by default. You don't need to turn on anything else, just point the lens at the image, and the system will analyze the frame itself.
However, if automatic recognition doesn't work, it may be disabled in the settings. To activate it, open the camera app, click on the three bars in the top corner and select Settings. In the list that opens, find the Code Scanner or Scan documents switch and make sure it's active.
💡
If the camera is focused but the link doesn’t appear, try slightly changing the distance to the object or the angle of the smartphone for better lighting of the code matrix.
After a successful read, a pop-up notification with a link or action will appear on the screen. MIUI frequently URL-The address for threats before the transition, which is an important security element, if the code contains contact details or text, they will also be displayed in a way that is understandable to the user.
- 📸 Hover the camera over the code without using flash in good lighting.
- ⚙️ Check the camera settings if automatic recognition is not working.
- 🔗 Click on the notification that appears to click on the link or perform the action.
⚠️ Note: Do not follow the links from QR-codes obtained from unknown sources, as they may lead to phishing sites, imitating banks or popular services.
It is worth noting that in some regions or on global firmware, the algorithms of the camera may differ, and if the standard method does not work, it does not indicate a malfunction of the device, but only indicates the features of the software in your location, in which case it is worth resorting to alternative methods, which will be described below.
App Scanner and Google Lens
If the built-in camera doesn't work, or you need a deeper image analysis, the Scanner system app comes to the rescue, and unlike a simple camera, this tool is designed to work with codes and documents, providing additional features, and it is often located in the Tools folder on the desktop or in the menu of all applications.
Inside the Scanner application, you can choose the mode of operation: scanning codes, documents or translating text. QR-Code mode is available, which allows you not only to read data from the screen, but also to download saved images from the gallery. This is especially useful if you received a screenshot of the code in the messenger.
The alternative is Google Lens, which is integrated into many Android system applications, and you can call it up via Google’s search widget or directly from the camera interface if it’s enabled. Google’s algorithms often handle corrupted or poorly lit code better than standard solutions.
- 📂 Open the Scanner application from the folder Tools for advanced functions.
- 🖼️ Use the gallery button inside the scanner to upload photo code.
- 🔍 Google Lens helps you recognize text and objects beyond codes.
An important advantage of using Google Lens is the ability to translate text in real time, which can be useful when scanning codes with foreign text. The system analyzes the image through cloud services, ensuring high accuracy.
Scan through Control Center and curtain
To maximize the speed of access to the scanning feature, Xiaomi developers have implemented the ability to output the scanner to the Control Center, which allows you to read the code without unlocking the phone completely or without looking for an app icon, this approach is especially convenient in situations where you need to quickly log in or pay for a purchase.
To add a scanner, lower the notification curtain down and tap the edit icon (usually a pencil or gear).In the list of available switches, find the Scanner or Scan element and drag it to the active zone. Now it will always be on hand in the top bar.
☑️ Quick access settings
Once you add a widget, it takes seconds to read: swipe down, tap on the icon, hover the camera. Some users prefer to label the Scanner app directly on the desktop or in the folder of frequently used programs, which creates a backup path if the widget in the curtain for some reason does not work.
The fast scanner is identical to the full application, but the interface is simplified for speed, it immediately opens the viewfinder and focuses on the code. Once read, the action is instantaneous, which is critical in times of high load, such as at the checkout of a store or when entering a transport.
Comparison of scanning methods on Xiaomi
Different methods of activating the scanner have their advantages and disadvantages depending on the situation, and understanding these differences will help you choose the best option for everyday use.
| Method | Speed of access | Demands the Internet. | Additional functions |
|---|---|---|---|
| Standard camera. | Tall. | No (to follow the link) | Basic recognition |
| Appendix Scanner | Medium | No. | Document scan, gallery |
| Google lens | Medium | Yes. | Translation, object search |
| Widget in the curtain | Maximum | No. | Quick launch. |
As you can see from the comparison, the widget in the notification curtain provides the highest access speed, making it an ideal choice for frequent use. The standard camera is good for its autonomy, without requiring unnecessary actions to run. Apps like Google Lens win in intelligent image processing.
The choice of method also depends on the personal preferences and habits of the user: some prefer to keep the desktop clean and use a curtain, others are more comfortable with having a separate icon.
Solving Code Recognition Problems
Sometimes users are faced with a situation where the camera simply does not see the code or gives an error. The first reason is often contamination of the camera lens. Wipe the lens with a soft cloth, as fatty traces can scatter light and interfere with focusing on the small details of the code.
The second common problem is poor lighting or glare. QR-codes don't read well when bright light hits the glossy surface on which they're printed directly. Try changing the angle of your smartphone or moving to a place with more uniform lighting.
What to do if the code is damaged?
It’s also worth checking the app’s permissions. Go to Settings → Apps → All apps, find the Camera or the Scanner and convince the ertes that they have access to the camera and storage. Without these permissions, the app may not work properly or save scan history.
⚠️ Note: If the code is on the screen of another device (monitor, tablet), reduce the brightness of your screen or screen source to avoid illumination and moire, interfering with reading.
In rare cases, the problem may lie in a software failure of the MIUI shell itself. Cleaning the camera application cache through the settings menu often helps restore the correct operation. If nothing helps, rebooting the device can eliminate temporary process conflicts.
Security and verification of references
Security in code scanning is a critical aspect that is often overlooked. QR-The code may contain not only a link to the site, but also a command to add a contact, send a message. SMS Or connect to a Wi-Fi network. Always look carefully at a pop-up notification before confirming an action.
System system MIUI Guard and Google Play Protect’s built-in security mechanisms automatically check URL-If a site is marked as dangerous, the browser or scanner will issue a warning, and it is strongly advised not to ignore such warnings, as this can lead to identity theft.
💡
Always check the domain name in the link before clicking, even if it comes from a familiar person, as their account may have been hacked.
For enhanced security, you can use special analysis apps that show the content of the code without clicking on a link, which makes sure that the address is actually inside, and not a disguised malicious script, such applications are available in the GetApps store or Play Market.
- 🛡️ Always check the site address before entering passwords or card details.
- 🚫 Do not install applications from unknown sources by linking from QR.
- 👀 Pay attention to the warnings of the antivirus system.
Remember that scammers often use short links or URL shortening services to hide their real address. In such cases, it is better to use online services to decrypt short links before clicking. User vigilance is the line of defense against digital threats.
