Modern smartphones of Xiaomi have become universal tools for interaction with the digital world, where QR-Codes have become the de facto standard for fast data exchange, and whether it's logging in to Wi-Fi, paying in a store, or clicking on a link, quickly reading a cipher becomes a critical skill. Owners of Redmi and Poco devices often wonder where to find this feature, as interface manufacturers hide it in different ways.
Unlike earlier versions of Android, which required a third-party app, today the QR scanner is built deep into the system components of the MIUI shell and the new HyperOS. This means that you do not need to download dubious software from the Play Market store, which can request unnecessary permissions, just know the right activation paths or hidden gestures.
In this article, we will look at all possible ways to read codes, from a standard camera to desktop widgets, and we will also touch on security issues, since scanning code from an unverified source can lead to phishing, and discuss what to do if the camera stops focusing on black and white squares.
Use of the standard Camera application
The most obvious and quick way to activate a barcode scanner is to use the Camera app, which Xiaomi has integrated the pattern recognition algorithms directly into the viewfinder, but this feature is not always active by default and may require manual activation in settings.
To get started, open the app and hover the lens over the code. If nothing happens, try clicking on the "More" button or swiping to the right to find the "Scanner" mode. In some versions of the firmware, just point the camera and the link will pop up automatically, but often you need to press the shutter button or a special scan icon.
It's important to understand the difference between Photo mode and Scanner mode. In normal photo mode, the system can ignore the system. QR-Labels to avoid accidental clicks while shooting documents.Scanner mode is specifically optimized for contrast recognition and works even in poor lighting.
💡
If the camera can't see the code, try changing the distance to the object or wipe the lens. Fat spots often scatter light, interfering with focusing algorithms.
If automatic recognition doesn't work, check the settings. Go to the camera menu (three bars in the corner) and find "Scan" QR-Make sure the switch is active. On some Redmi Note models, this option may be called Google Lens or be combined with augmented reality features.
Specialized application Scanner in MIUI
In the Xiaomi ecosystem, there is a separate system application called the Scanner, which differs from the camera in its advanced functionality and document processing, and can be found in the Tools folder on your desktop or through an application search.
This app can not only read links, but also translate text, recognize goods and even transfer currency. When you run, you will see an interface with several tabs. QR-The codes use the default default mode, and the recognition algorithm is more aggressive, instantly reading data without having to take a picture.
- 📷 Image: allows you to select a finished photo from the gallery if the code was saved by a screenshot.
- 🛒 Product: a specialized mode for searching for products in online stores by barcode.
- 📄 Document: Aligns perspective and improves readability of text when scanning papers.
- 🌐 Translation: Overlays real-time translation of text over the original through the camera.
Special attention should be paid to the scanning function from the gallery. QR-Instead of taking a screenshot of another device's screen, you can just open the Scanner app, click on the gallery icon, and select the file.
☑️ Checking the scanner settings
Scanning through Control Center and widgets
For those who appreciate speed, MIUI 12, 13, 14 and HyperOS have quick access, so you don't have to look for an app icon every time, just lower the notification curtain or open the Swipe Control Center from the top right corner.
In the list of fast switches (where Wi-Fi and Bluetooth are) there may be an icon called Scanner. If it's not there, click on the edit button (usually a pencil icon or three dots) and drag the scanner icon to the active panel. Now it takes one second to access the code readout.
Another convenient way to do this is to use widgets. You can put a scanner widget or a quick start widget on your desktop. In newer versions of the interface, if you press the blank space of the screen long enough and select Add widgets, you'll find tools from System that allow you to run the scanner in one tap.
⚠️ Note: Do not add scanner widgets from unknown developers. Use only Xiaomi system widgets or proven applications, as the widget has direct access to the camera and can broadcast the image without your knowledge.
Using widgets is especially convenient on Xiaomi Pad tablets or large-screen smartphones, where finding an icon on the menu can take time.You can take the scanner to the home screen or to negative tape (Mi Vision / Google Discover), making the feature as accessible as possible.
Use of Google Lens and Browsers
If Xiaomi’s standard tools don’t work for some reason, you can always turn to the Google ecosystem.The Google Lens service is built into most Android smartphones and often works even more accurately than native solutions, especially with complex or corrupted codes.
You can run Google Lens through the Google search widget on your desktop (camera icon in the search bar) or through the Google Photos app. Open any photo with QR-And then you can use the code, and the system will suggest you click on the link, which is ideal if you don't have Internet access to load the page, but you need to copy the text or the Wi-Fi number.
Browsers also have built-in scanners, such as Chrome or Yandex.Browser, where the address bar often has a camera icon, and clicking on it activates the scanner, which will immediately open in a new tab, which is convenient because it doesn't require you to leave the context of the browser.
| Method | Launch speed | precision | Additional functions |
|---|---|---|---|
| Appendix Camera | Tall. | Medium | Minimum |
| Appendix Scanner | Medium | Tall. | Translation, Goods |
| Google lens | Medium | Very high. | Search, Text |
| Desktop widget | Instant. | Depends on the app. | No. |
The choice of method depends on your specific task. For quick payment or login to Wi-Fi, the native MIUI scanner is best suited. Google Lens is indispensable for working with text or searching for information about goods.
Problems with focus and scan quality
Sometimes users are faced with a situation where the Xiaomi phone simply does not see the code, although other devices read it without problems. Often the reason lies in the camera settings or the physical condition of the lens. Macro mode can interfere with focusing over long distances, and the main module can not focus close.
Try to manually tap the screen in the area where it is located. QR-If that doesn't work, change the distance to the object. Some Redmi camera modules have a fixed focus in scanner mode, so you need to find the middle ground, usually in the middle of the scanner. 10-15 sm.
Another common problem is the low brightness of the screen you're reading the code from. If you're scanning code from another computer or phone's monitor, increase the brightness of the source. The anti-glare coating on the screens can create rainbow glares that knock down the recognition algorithm. Try changing the angle of the device.
⚠️ Attention: If the camera stops focusing on any object at all, it may be a software failure of the camera service. Try clearing the Camera app cache in your phone settings or restarting the device.
It’s also worth checking if you have Do Not Disturb mode enabled or special filters in the camera that can make the image black and white or too contrasting, which breaks the structure. QR-Resetting camera settings to factory settings often resolves software conflicts.
What to do if the code is damaged?
Safety in scanning QR-code
Although technology QR-It's convenient, it carries certain risks. Attackers can create code that leads to a phishing site that copies a bank page, or initiate a hidden subscription to paid services. Unlike a regular link, you don't see your destination address until you scan the code.
Modern versions of Android and HyperOS shells have Google Play Protect built-in, which checks links before opening. However, you should not rely on it. Always pay attention to the confirmation pop-up: if the code suggests opening an application or going to a strange domain, double-check the source.
Never scan codes pasted in public on questionable stickers on top of the original ad. This is a classic social engineering method. If the code leads to a site asking for card or password details, make sure the browser address bar contains the correct domain and https protocol.
- 🔒 Verification URL: Always look at the address bar before entering data.
- 🚫 Opt-out: If the code offers to download APK-File outside the Play Market – refuse.
- 🛡️ Antivirus: Use Xiaomi’s built-in security scanner before clicking on links.
Remember, on your own. QR-The danger is the action that the phone will take after reading it. Be careful, especially when paying for services or logging in to important services.
💡
The key to security is trusting the source of the code, not the code itself. If you don't know who created it, don't point the camera.
