Modern smartphones have become versatile tools, and the Xiaomi Redmi Note 7 is no exception. One of the most sought-after features that users often search for is the ability to quickly read graphic codes. These black and white squares can contain links to sites, data for connecting to Wi-Fi, contact information or text.
Owners of MIUI-based devices sometimes have difficulty finding built-in scanning features, because the algorithms for the camera and system applications may vary depending on the firmware version, but Redmi Note 7 has several effective methods for solving this problem without having to download dubious software.
In this guide, we will take a look at the system’s regular tools, Google services capabilities, and alternatives, and you will learn to instantly click on links, pay for purchases, and connect to networks just by pointing the camera lens at the image, and understanding these mechanisms will make it much easier to use your gadget every day.
Use of built-in scanner in the Camera application
The most obvious and quick way is to use the standard Camera app, and in the more recent versions of the MIUI shell, the code recognition function is built directly into the shooting interface, so you don't have to search for separate menus, you just have to run a standard photo app.
However, on some versions of the firmware for Redmi Note 7, this feature may be hidden or require activation. If nothing happens when getting stuck on the code, try clicking on the menu icon or swiping the screen. The system will automatically analyze the image in the viewfinder and suggest an action if it recognizes a familiar pattern.
⚠️ Warning: Automatic recognition may not work in poor light or if code is corrupted.Make sure the camera lens is clean and the image on the screen is clear.
To activate the manual scanning mode inside the camera, you often need to switch to a special mode. In the list of shooting modes, find the Scanner or More → Scanner. This mode is optimized specifically for reading data, it focuses faster and ignores attempts to take a photo, immediately moving to decoding information.
💡
If automatic recognition in photo mode is slow, force switch to the Scanner mode in the camera mode menu for instant reaction.
Mi Scanner and Google Lens App
If the standard camera doesn't work, the Mi Scanner system app comes to the rescue, and unlike the regular camera, this tool is designed exclusively for code and text, and it's often pre-installed in the Tools folder on the desktop.
The second powerful tool available on the Xiaomi Redmi Note 7 is Google Lens, which is integrated into Google’s search box or is caused by a long tap on the screen (a feature of Google Assistant), which uses cloud algorithms and often recognizes even complex or distorted codes better than the usual means.
Both applications allow not only to open links, but also to perform other useful actions:
- 📱 Copying text from paper media in the smartphone clipboard.
- 🛒 Search for products on the Internet by image or code.
- 📶 Automatic connection to Wi-Fi network without entering a password.
- 📞 Saving contact information (vCard) directly to the phone book.
Scanner in the control center and notification curtain
For those who prefer speed, MIUI provides the ability to display the scanner in the control center, which is especially convenient when you need to quickly read the code from the computer screen or from the billboard without opening unnecessary applications.
If you don't see the scanner icon in the quick settings list, you can add it manually. Press the edit button (usually a pencil icon or three dots in the corner of the menu) and drag the scanner icon into the active area, and then access the function will take just one touch.
Also worth mentioning are widgets, which can be placed on the desktop with a scanner widget that will run the function at a single click, and this is relevant for users who often use payment systems or attend events with electronic tickets.

Comparison of scanning methods on Redmi Note 7
The best way to do this depends on your goals, and each method has its own advantages depending on the situation, and a camera will do it for quick check of the link, and specialized applications will do it for text.
Below is a table that will help you decide on the choice of tool for specific tasks on your device:
| Method | Speed of operation | precision | Additional functions |
|---|---|---|---|
| Appendix Camera | Tall. | Medium | Basic |
| Mi Scanner | Medium | Tall. | Translation, Text |
| Google lens | Depends on the network. | Maximum | Search, Goods |
| Centre for control | Instant. | Tall. | No. |
Note that Google Lens requires an active Internet connection to allow some features to function properly, while Mi Scanner can work offline. This is an important nuance if you are in a low-reception zone.
Setup of permissions and troubleshooting problems
Sometimes the scanner may not work due to the lack of necessary permissions. Android system strictly controls the access of applications to the camera. If there is an error or a black screen when you start the scanner, check the privacy settings.
Go to Settings → Applications → All apps. Find the Scanner or Camera in the list. Make sure the Permissions section ticks the camera box. Without that access, the app won't be able to physically see the image.
⚠️ Note: If after granting permissions, the camera in the scanner shows a black screen, it is possible that another process blocks access to the camera module.
Problems can also arise from optical contamination: The Redmi Note 7's main camera has a high resolution of 48 MP, but even the slightest fingerprint can defocus the image, and the scanner can't read the data.

Safety in scanning QR-code
Use of the QR-Not only is it convenient, but it also carries risks, and attackers can create codes that lead to phishing sites or initiate hidden actions, such as sending a paid payment. SMS. Xiaomi Redmi Note 7 has built-in protection, but user alertness is the main security factor.
Before you click on a link from an unknown source, look carefully at the site address. If the URL looks suspicious or contains typos in the name of a well-known brand, clicking on it is strongly discouraged. System scanner usually warns about potentially dangerous sites, but can not always recognize a new threat.
The basic rules of digital hygiene when working with codes:
- 🔒 Do not scan codes pasted over original stickers in public places.
- 👁️ Always check the pop-up notification before clicking on the link.
- 📵 Do not allow the site to access contacts or files without urgent need.
- 🛡️ Use antivirus software if you scan codes from unverified sources frequently.
