Modern smartphones, and Xiaomi Redmi Note 5 is no exception, have become universal tools for interacting with the digital world. One of the most convenient ways to quickly transfer data, log in to websites or pay for purchases has become the use of the Internet. QR-These black and white squares contain encrypted information that can be easily read by your device's optics. URL-addresses or complex passwords.
However, despite the simplicity of the technology, owners of the popular Redmi Note 5 often have difficulty reading code. A standard camera may not respond to an image, or the system does not have an obvious scan button. This is due to the features of the MIUI shell, which has its own specific settings and pre-installed applications. Understanding where to look for the right tool will save you time.
In this guide, we will take a closer look at all the ways you can activate the scanner on your gadget, look at both the built-in features of the system and third-party solutions that are guaranteed to work on Android, and learn how to quickly read codes from the screen of another device or from paper media.
Use of built-in scanner in the Camera application
The most obvious and quick way to activate code reading is to use the standard Camera app. In the latest MIUI firmware versions available for the Redmi Note 5, developers have integrated pattern recognition algorithms directly into the shooting interface, and you don't have to search for individual apps or download additional software if your version of the system is updated.
To start, you just have to run the application through a shortcut on the desktop. QR-The system must automatically analyze the image in the viewfinder. If the function is active, you will see a pop-up notification or click button directly on the screen.
Sometimes automatic recognition doesn't work the first time, and it could be due to insufficient lighting or too fast a hand movement, so try to stick with the code for a few seconds, and make sure that the camera settings include the option of Code Scanner or Google Lens, as this feature can be called differently in different regions of the firmware.
If you don't see a response to the code, it's possible that your version of MIUI has disabled the default feature or removed it. Then check the settings of the app itself. Click on the three bars in the corner of the screen and look for the scan item, which depends on the specific software build installed on your Redmi Note 5.
⚠️ Note: Do not attempt to take a photo of the code unless the camera recognizes it automatically. A regular shot in the gallery will not open the link yourself, you will still have to search for the code in the photo through special features.
💡
Keep your phone 15-20 cm away from the code for better focus. Too close blurs the image, and the farthest one prevents the camera from reading details.
Wipe the lens with a soft cloth before use, as fatty fingerprints significantly reduce contrast and interfere with algorithms.
App Scanner and Google Lens
If the standard camera doesn’t work or doesn’t have the right function, there’s a system app called Scanner on your smartphone, a separate tool from Xiaomi that’s designed to read different types of codes, including QR, product barcodes, and documents, and can be found in the Tools folder on your desktop.
When you run the Scanner app, you get access to more advanced settings, and you can choose the mode of operation: code scanning, text translation, product search, for our task, we choose the standard mode, point the camera at the image, and click on the link will happen almost instantly, which is considered the most reliable method for Redmi devices.
The alternative is Google Lens, which is built into many of the search giant's services. On the Redmi Note 5, it's often integrated into the Google app or accessed through the search widget. By clicking on the camera icon in the search bar, you activate a powerful AI algorithm.
- 📸 High speed recognition even in poor light.
- 🌐 Translation of text from code in real time.
- 🛒 Automatic search for goods by barcode in online stores.
- 🔍 Recognition of animal and plant species through the camera.
Using Google Lens is especially important if the built-in Xiaomi scanner is not working properly for some reason. It is a cross-platform solution that receives regular updates regardless of the version of MIUI. It is enough to have a Google account and Internet access for full functionality.
It’s worth noting that Google Lens can request additional permissions to access geolocation or contacts to extend functionality, which is normal for smart assistants, but the user can always reject the request, leaving only the basic camera feature.
Setting up the scanner widget on the desktop
For those who use QR-In codes every day, constantly searching for an app on a menu can be an annoying factor. MIUI It allows you to put the scanning function directly on the desktop in the form of a widget, which greatly speeds up the process of accessing the tool and makes it more convenient to use.
To add a widget, you need to pinch the empty space on the desktop with your finger before the edit menu appears. At the bottom of the screen, select Widgets. In the list that opens, find the category "Tools" or immediately "Scanner." Drag the icon to the free area of the screen.
Now, a single touch is enough to scan. The widget can be of different size and design depending on the theme installed on your Redmi Note 5. Some themes offer animated icons that make the process more visually pleasing.
In addition, some versions of the firmware have a scan function through the control panel. Swipe from top to bottom to open the notification curtain, and find the Scanner button there. If it's not there, click on the pencil or edit button in the upper right corner of the curtain and drag the scanner icon to the active zone.
| Access method | Launch speed | Action required | Dependence on the MIUI version |
|---|---|---|---|
| Appendix Camera | Tall. | Open the camera, bring it in. | Tall. |
| Appendix Scanner | Medium | Find it in the folder, run it. | Low. |
| Widget on the table | Very high. | One touch. | Medium |
| Control panel | Tall. | Swipe, press. | Medium |
Customizing your workspace is a key part of smartphone use, with scanner widgets taking up a minimal number of pixels, but saving seconds every time you need to pay for a quick fare or log into Wi-Fi, which is especially important in situations where the bill is only seconds.
Scanning images from the Gallery
Often there is a situation where QR-It's a little bit of a code that's sent to you in the messenger as a picture or stored in your phone's memory, and it's not easy to scan the screen of another smartphone, and you can't always print, MIUI Allows you to read codes directly from files stored in the Gallery.
Open the image with the code in the standard Gallery app. In the bottom menu or in the menu "More" (three dots), there is often a button "Recognize" or the icon of Google Lens. Clicking on it will start the analysis of the image, the system will highlight the found codes and suggest to click on the link.
If the gallery's built-in tools don't read the code, you can use Google's Image Search feature. Open the image, click Share, and select Google Lens or Google Photos from the app list. Artificial intelligence will analyze the image and give you the result.
⚠️ Attention: When scanning screenshots, make sure that the image quality is high.Compression when sent via messengers can worsen the clarity of lines, which will make the code unreadable.
This is also useful for archiving data, so you can save important code as a picture, and if you need to quickly extract information from it without using a second camera, and it creates a convenient digital cycle of working with data.
What to do if the code is damaged?
Third-party applications for complex cases
In rare cases, Xiaomi’s regular tools may not be able to handle specific or corrupted codes, and third-party solutions from the Google Play Market come to the rescue, often with more flexible sensitivity settings and additional story features.
One of the popular solutions is Gamma Play's QR & Barcode Scanner app or Kaspersky's analogues, which offer a clean, ad-free interface and quick scanning. Once installed, just give the camera access and hover the lens.
The advantage of third-party apps is that they have an extended scan history, and if you accidentally close a link, it's easy to find in the history of the application, and many of them are able to create their own. QR-codes that can be useful for exchanging contacts.
- 📜 Detailed history of all scanned codes with dates.
- 🎨 The ability to create your own codes of any color and shape.
- 🔒 Checking links to viruses before switching (in antivirus scanners).
- ⚙️ Configuring the data output format (text, URL, vCard).
When installing third-party software, carefully monitor the permissions requested. The scanner does not need access to your contacts or microphone unless it explicitly states such features.
Using proven apps from well-known developers ensures the security of your data. avoid little-known programs with a lot of advertising, as they can slow down your Redmi Note 5.
Solving Focus and Reading Problems
Sometimes users find that the camera just can't see the code, even though it's clearly in the frame. Most often the problem is in focus. The Redmi Note 5 camera has phase autofocus, but in macro mode it can "scour." Try tapping the screen in the area of the code to force focus.
Another common cause is dirt on the lens. The camera in your smartphone is in constant contact with the environment. Wipe the camera area with a soft cloth without pile. Even a greasy, invisible trace can scatter light and interfere with reading contrasting black and white images.
If the code is on the screen of another device (for example, a laptop), there may be glare or moire (rickets on the screen).In this case, try to change the angle of the phone relative to the source screen. Do not hold the phone strictly perpendicular, a slight tilt often removes the lights.
☑️ Diagnostics of scanning problems
In case of software failures, cleaning the Camera app cache will help. Go to Settings → Apps → All Apps → Camera → Memory and press Clean. This will reset the camera module settings without deleting your photos.
💡
90% of scanning problems are solved by simply cleaning the camera lens or changing the angle of the phone relative to the code.
If nothing works, check if you have Do Not Disturb mode enabled or special camera filters that can invert colors or change contrast, making the code unreadable for algorithms.
Security in Code Scanning
QR-Not only are codes convenient, they are potentially dangerous. Attackers can place codes that lead to phishing sites or initiate malware downloads. The camera itself is not dangerous, but the action it performs (clicking on a link) can be risky.
Always pay attention to the site address that appears before you click. If a short URL looks suspicious or the domain name is different from the service you expect, refrain from switching. Xiaomi Redmi Note 5 has built-in protection, but human factor remains the main security link.
Do not scan codes placed in suspicious places: pasted over original codes at stops, in elevators or received from unknown persons in messages. Fraudsters often use the "sticker bombardment" method, pasting legal codes with their own.
⚠️ Warning: Never enter credit card details or passwords on sites opened through code scanning from an unverified source. Always double-check your browser address bar.
Using antivirus crawlers or apps with link checker features adds an additional layer of protection: They analyze URLs in a database of known threats before opening a page in the browser.
Digital hygiene will allow you to use the technology QR-The technology is evolving as a standard for interaction with the city and services, and the ability to use it safely is an important skill of the modern user.
