Modern smartphones like Xiaomi Redmi 10 have evolved into versatile tools for interacting with the digital world, and one of the most sought-after features has become the reader. QR-These black and white squares are now used everywhere: for payment in stores, Wi-Fi connection, clicking on links or logging in to instant messengers, users no longer need to search for third-party apps, because the system is not a good place to use them. MIUI Offers built-in solutions for instant recognition.
However, many device owners have difficulty getting to know the feature first without knowing exactly where the tool is hiding or why the camera is ignoring the code. Often the problem lies in the lack of the necessary permissions or the wrong angle of shooting. In this article, we will take a detailed look at all the available scanning methods on your gadget so that you can use its potential 100%.
It’s important to understand that the image processing algorithms in Redmi 10 are fast enough, but require minimal customization to work smoothly. We’ll look at both standard methods through the system camera and specialized utilities from Google and Xiaomi that can already be installed on your device.
Standard method through the Camera app
The most obvious and quick way to activate the scanner is to use the standard Camera app, which is already preinstalled on your Xiaomi Redmi 10. Android and MIUI developers have integrated the code recognition function directly into the viewfinder, which allows you not to switch between applications.
However, by default, this feature can be disabled in the settings of the app itself to avoid accidental triggers during normal shooting. To activate the mode, open the camera, click on the three horizontal bars in the upper right corner and select Settings. In the menu you need to find the "Scan" switch QR-codes and put it in an active position.
⚠️ Warning: If the camera stops focusing on normal objects after the feature is turned on, try clearing the lens or restarting the application, as macro shooting mode may conflict with autofocus.
After turning on this option, when getting stuck on the code, a yellow frame or a pop-up notification will appear on the screen with a suggestion to click on a link or copy the text. The system automatically determines the type of content: if this is the case, URL-address, a transition button will appear; if the text is a suggestion to copy it to the clipboard.
For best results, keep the phone still for 1-2 seconds. The pattern recognition algorithm should analyze the contrast and geometry of the tag. If the code is damaged or glued to a glossy surface that creates glare, the camera may not read the information the first time.
⚠️ Note: Do not try to scan codes from other devices at maximum brightness, as the flickering of the matrix (PWM) can prevent the correct reading of data by the Redmi 10 camera.
Use of Google Lens (Google Lens)
If the standard camera doesn't do the job for any reason, or if you want to get more functionality, Google Lens comes to the rescue. It's a powerful AI tool that's built into most of Google's Android services, including Redmi 10. It lets you not just read links, but also translate text, Objects, and search for goods.
There are a number of ways to run the scanner, and the easiest way is through a widget on your desktop or through Google search bar, and often the lens icon (a colored square with a circle inside) is located right in the search bar, and you click on it and you activate the camera with advanced real-time image analysis features.
The advantage of Google Lens is its ability to work even with fuzzy or partially closed codes. Google's algorithm tries to "finish" the missing parts of the image from its database. In addition, there is an overlay feature here where you can highlight a specific area of the frame to scan if there are other distractions around the main code.
Google Lens can also save your scan history, which is a very useful feature if you accidentally close a link but forget to copy it. Unlike the standard camera, which often works on a see-forget principle, all actions are logged into your Google account.
- 📷 Click on the lens icon in the Google widget or in the Google Photos app.
- 🔍 Put the camera on QR-code and wait for the area to be allocated.
- 📥 Click on the “Open” or “Copy Text” button that appears at the bottom of the screen.
- 📂 Check the history in the section "Library» -> «A lens to find old codes.
It is worth noting that some advanced features, such as real-time text translation or search for products by photo, will require an active Internet connection. QR-The codes can also work offline if the necessary language packs are already downloaded to the device.
💡
Keep the important ones. QR-codes (such as Wi-Fi or pass codes) in Google Photos – then you can scan them at any time directly from the gallery without printing them again.
Scanning through the built-in scanner in the menu
The MIUI shell on the Redmi 10 often features a separate system app or widget called the Scanner, which, unlike the camera, is designed to work exclusively with codes and bar markers, making it more stable in difficult lighting conditions.
You can find it by pulling down the notification curtain (control panel). Among the quick access buttons (Wi-Fi, Bluetooth, flashlight) you can find the Scanner icon. If it's not there, click on the edit button (usually a pencil or three dots) and add the Scanner shortcut to a prominent place, which will allow you to run the function with a single touch, even without unlocking the phone completely (depending on the version of MIUI).
This module often works faster than the camera, because it does not waste resources on autofocus for photos or videos, and immediately goes into the mode of constant search for the matrix of code, this is especially true when you need to quickly punch through the product in the store or pay for the fare, where every second is important.
The scanner interface is usually minimalistic: you can see the frame in the center of the screen, and the bottom shows the history of the last codes scanned. This is convenient if you scanned the code, but you didn't click on the link right away, and then the phone is locked, and you can find the right link in the history without re-scanning.
⚠️ Attention: The scanner in the notification curtain may not work if the Security or Scanner app does not have permission to use the camera.
☑️ Checking the scanner settings
Problems with focus and scan quality
Despite the presence of a macro lens module in the Xiaomi Redmi 10, users sometimes complain that the camera “cannot see” the code or constantly defocus. Most often the problem lies in the distance: modern wide-angle cameras do not focus well on objects located closer to 10-15 centimeters.
If the code is small (for example, on a business card or on a screen of another smartphone), do not bring the phone close. 20-30 So if you look at this, you can use digital zoom, or you can just wait until the system picks up its focus, and a higher-resolution main camera can do this better than a wide-angle camera.
Another common cause of failure is a dirty lens. Fat spots from your fingers scatter light and create a "fog" effect, causing the contrast of the black and white pattern to fall below the threshold of recognition by the algorithm.
Lighting is also worth considering. In bright sun, you can get glare on glossy code surfaces, and in the dark, the built-in flash can illuminate the center of the image, making the code white. In low light, you better use Night mode or turn on a permanent flashlight if the scanner allows.
If nothing works, try flipping your phone or changing the angle of inclination.A straight angle of 90 degrees isn't always optimal because of the reflections; a slight tilt often helps the camera better "grab" the code structure.
Table: Comparison of scanning methods
To make it easier for you to choose the right tool for a particular situation, we have prepared a comparative table of the main methods of scanning on Redmi 10.
| Method | Speed of operation | Demands the Internet. | Additional functions |
|---|---|---|---|
| Appendix Camera | Tall. | No (to open the link) | Basic Recognition of Links and Text |
| Google lens | Medium | Yes (for extended features) | Translation, search for goods, copying of text |
| Scanner in the curtain | Very high. | No. | History of scans, work with barcodes |
| Third-party annexes | Depends on the software. | Often Yes (advertising) | Code generation, history in the cloud |
As you can see from the table, for everyday tasks like paying or going to the site, it's best to use a built-in camera or scanner in the curtain, which provides a balance between speed and functionality without putting too much strain on the system.

Security in Code Scanning
Use of the QR-In addition to being convenient, attackers can create codes that redirect to phishing sites masquerading as legitimate resources, or initiate hidden actions, such as sending paid messages. SMS (But on modern Android, it is blocked).
Xiaomi Redmi 10 has built-in protection mechanisms, but the user should be vigilant.Never scan codes from unverified sources, such as stickers on poles or random images on the Internet.Always pay attention to the address of the site that appears in the pop-up window before you click.
If a link looks suspicious (a lot of random characters, an unusual domain), do not click on it. APK-App files bypassing the Google Play Store, which can lead to malware infection.
For additional protection, you can use antivirus solutions that check URL-Real-time addresses. Built-in security scanner MIUI It can also alert you to potentially dangerous sites if your database is updated.
- 🛡️ Always check the domain name before clicking on the link from QR-code.
- 🚫 Do not enter personal data on sites opened through unknown codes.
- 📱 Use built-in protections MIUI Google Play Protect.
- 🔒 Beware of codes that promise “free money” or “virus checks».
Remember, on your own. QR-Code is just text, but the actions it initiates can be dangerous.Critical thinking remains the ultimate security tool in the digital age.
💡
Xiaomi and Google’s built-in crawlers have protection against known phishing sites, but they can’t guarantee 100% security against new threats, so visual link verification is a must.
