Modern smartphones have become universal tools, and Xiaomi Redmi Note 7 is no exception. One of the most popular features is the ability to read graphic codes that contain links, passwords from Wi-Fi or contact information. Users often search for an answer to the question of how to scan the QR code on the Xiaomi Redmi Note 7, since there is no single standard for the location of this feature in MIUI. Device owners are faced with the fact that the usual button in the camera may be missing or hidden in the depth of the menu.
This guide will help you understand all the ways you can, and we will look at both the standard Android system and the MIUI shell, as well as proven third-party solutions, and learn to quickly access information encoded in black and white squares, without unnecessary complexity.
We will focus on security settings, as scanning codes from unverified sources can carry risks, and we will also address the typical camera focus issues that often interfere with the process on the Redmi Note 7 model. Follow the instructions to turn your smartphone into a powerful tool for interacting with the digital world.
Built-in scanner in the Camera app
The most obvious and quick way is to use the standard Camera app. MIUI The developers have implemented code recognition support right into the viewfinder, but on the Redmi Note 7, this feature can behave differently depending on the firmware version. QR-code in the frame and suggests to go to the link.
If automatic recognition doesn't work, you should check the settings. Click on the three bars in the upper right corner of the camera interface and select Settings. Here you need to find the item associated with the code scanner or Google Lens and activate it. Without this step, the camera will just take pictures, ignoring graphics tags.
Sometimes it helps to switch shooting modes. Swipe your finger across the screen in photo mode left or right to find Documents mode or special scanner mode. In some regions, this functionality is cut off, so if you did not find these options, then your version of the software does not support native scanning without additional actions.
⚠️ Note: When the camera hovers over the code, the system can immediately open the link in the browser. Make sure that the site domain is trusted before entering personal data.
For ease of use, you can add a scanner widget to your desktop. Hold your finger on the blank spot of the screen, select Widgets, and search for a Scanner or Google Lens in the list, which will allow you to run the function with one touch, bypassing the camera menu.
Use of the Mi Scan (Scanner) application
Most Xiaomi devices have a proprietary Mi Scan app (or just the Scanner) preinstalled, which is more advanced than the standard camera because it can recognize not only links, but also goods, business cards and documents, and can be found in the Tools folder on the desktop or through a search system.
When you run the app, you'll see the interface with the scan button in the center. You'll point the Redmi Note 7 lens at the code. The Mi Scan is faster and more stable because it's designed for this task. It also stores the scan history, which allows you to go back to the link you previously opened if you accidentally closed your browser.
☑️ Checking the scanner
An important feature is that you can scan from the gallery. If you have a stored image of the code, you don't have to look for the original. Open Mi Scan, select the image icon in the corner, and download the file from the phone's memory. The system will process the image itself and give the result.

Where to find hidden scanner in older versions of MIUI?
Integration of Google Lens (Google Lens)
Google’s ecosystem offers one of the most powerful recognition algorithms, the Google Lens. On the Redmi Note 7, it can be built into a Google or Google Photos app, a solution ideal for complex cases where Xiaomi’s regular tools can’t handle text recognition or corrupted codes.
To take advantage of this method, open the Google app (the search bar on your desktop). To the right of the text input bar is a color camera icon. When you click on it, you launch the lens mode. Point the camera at the code, and the system will suggest options: open the site, find the product or copy the text.
The advantage of Google Lens is that it has an artificial intelligence that understands context, so if the code leads to the product, it will show the price of the product in other stores, if it's text in a foreign language, it will offer instant translation. For the Redmi Note 7, it's a great way to expand the functionality without installing any extra software.
You can also use a Google search bar widget, and you can add it to the home screen, and the scanner button is always at hand, which is especially useful when you need to quickly read the code from the computer screen or from a billboard on the go.
Third-party apps from Google Play
If the built-in features don't suit you or don't work properly, you can always turn to third-party developers, there are thousands of code-reading apps on the Google Play store, but be careful: many of them are overloaded with ads or require unnecessary permissions.
It is recommended to choose simple and lightweight utilities that will not load the Redmi Note 7 processor. Open source applications or from well-known antivirus vendors will be a good choice. They guarantee data security and the absence of hidden miners.
- 📱 QR & Barcode Scanner is a popular app with minimalist design and history.
- 🔒 Kaspersky QR Scanner – checks links to viruses before switching, ensuring security.
- ⚡ Binary Eye - open-source scanner without advertising and unnecessary permissions, very fast.
⚠️ Warning: Avoid flashlight and scanner apps if they require access to contacts and microphones.
When installing third-party software, carefully read permission requests. The scanner only needs access to the Camera. If the application requests access to calls, SMS or geolocation without an explicit need, you better refuse to use it and delete the program.

Use Do Not Disturb mode when scanning important payment codes so that an incoming call does not interrupt the process and reset the payment page.
Solving Focus and Quality Problems
The Redmi Note 7 has a good camera, but over time, you can have problems with autofocus. If the camera can't catch the code, the image stays blurry and the reading doesn't happen. Often the cause is lens contamination. Wipe the camera with soft cloth, removing greasy spots and dust.
Another common problem is distance. Move the phone closer or further away from the code. The optimal distance for a Redmi Note 7 module is 10 to 30 centimeters. If you're too close, the macro mode may not work, and the focus will go to infinity.
In some cases, cleaning the camera app cache helps. Go to Settings → Apps → All apps → Camera → Memory and press Clear. This will reset the focus settings and can fix software glitches.
Settings → Applications → All applications → Camera → Memory → CleanIf the problem persists, check for a protective film on the camera module. Sometimes the factory film will become cloudy or scratched over time, which critically reduces image quality and prevents reading small details. QR-code.
Security in Code Scanning
QR-The codes may contain not only links to websites, but also commands to add contacts, connect to Wi-Fi or even install applications. The main danger is phishing. Attackers can place code leading to a copy of a bank's website to steal your data.
Always pay attention to the browser address bar after scanning. If the domain is different from the official one (for example, sberbank-secure.com instead of sberbank.ru), immediately close the page. Redmi Note 7 has built-in protection, but the human factor is more important than any protection.
- 🛡️ Do not scan codes placed on suspicious stickers on top of the original adverts.
- 🔍 Check it out. URL-address before entering passwords or card data.
- 🚫 Avoid codes that offer downloads APK-files from unknown sources.

Security comes first: Never blindly trust codes from unverified sources, always check the end address of the link.
Use antivirus solutions if you frequently use code in public places, they can analyze traffic and warn you of an attempt to switch to a malicious resource, which is an additional layer of protection for your Xiaomi.
