Modern smartphones, including popular Xiaomi models, have become universal tools for interacting with the world around them, where barcodes play the role of digital keys. Redmi 8T users often face the need to quickly read information from product packaging, connect to a Wi-Fi network or access restaurant menus simply by getting stuck a lens. The MIUI operating system has several built-in mechanisms for recognizing graphics tags, which eliminates the need to search and install third-party software.
However, despite the obviousness of the feature, many device owners do not know exactly where the tool is hiding or how to activate automatic recognition. A standard camera may not respond to codes without first setting up, and the menu interface sometimes changes after firmware updates. In this detailed guide, we will look at all possible ways to read data on your device, from native system functions to the use of specialized utilities from Google.
It is important to understand that the security of data when scanning codes from unknown sources lies entirely with the user. Malicious links can be disguised as harmless coupons or instructions, so always check the transition address before confirming the action. Below are proven methods to help you effectively use the capabilities of your Redmi 8T to work with two-dimensional barcodes.
Use of built-in scanner in the Camera application
The fastest and most obvious way to read code is to use the standard Camera app that is already installed on your Redmi 8T. Xiaomi engineers have integrated recognition algorithms directly into the viewfinder, which allows you to instantly respond to the appearance of a graphic tag in the frame. To start working, you do not need to configure anything, just launch the application and point the lens at the image.
Usually, the system automatically determines the presence of QR-If you don't, you can use the code to click on the link or copy the text, and if you don't, you can turn off the scanner function in the settings of the camera app itself. To activate it, open the camera, click on the three horizontal bars in the upper right corner (settings menu) and find the Document Scanner or Recognition switch. QR». Once this option is enabled, the phone will react to the codes automatically.
⚠️ Warning: When scanning codes through the camera, always pay attention to a pop-up notification if the link leads to a suspicious domain or requires immediate download. APK-file, refuse to transfer.
The quality of recognition depends on the lighting and the cleanliness of the lens. Rub the camera with a soft cloth before use, especially if you are in a room with artificial light. Also make sure that the code is in focus: tap the screen in the area of the code so that the camera sharpens, after which the reading will occur instantly.
💡
Keep your phone 10-15 cm away from the code for the fastest and most accurate readout without losing focus.
The Scanner app in the Tools folder
In the shell. MIUI, redmi-mounted 8T, There's a separate system application that often goes unnoticed by users, called the Scanner, and it's usually located in the Tools system folder on the home screen. This tool has advanced functionality compared to a conventional camera and supports recognition not only. QR-codes, but also documents, translation of text and even identification of plants and animals.
When you run the Scanner, you'll see an interface that's optimized for code, and unlike the camera, it's got no controls, and the scanning area is clearly defined, and the app automatically detects the type of code and suggests the appropriate action: open the site, add a contact, connect to Wi-Fi or show text, which is especially useful when dealing with large amounts of information or complex composite codes.
- 📱 Universality: Supports reading QR, barcodes of goods, business cards and documents.
- 🌐 Translation: Can translate text captured from images in real time through embedded services.
- 💡 Backlight: Has a built-in flash button to work in the dark, which is critical for Redmi 8T nightly.
If you can't find an app icon, use a global desktop search. Swipe down the center of the screen (or up, depending on your navigation settings) and type in the word "Scanner." The system will prompt you to run the desired component. You can also add a scanner widget to your desktop for instant access in one touch, which greatly speeds up the process.
Use of Google Lens (Google Lens)
For users who prefer the Google ecosystem or don’t find standard Xiaomi tools comfortable enough, Google Lens is a great solution.This app is pre-installed on most Redmi 8T certified devices and integrated into Google search, and is also available as a standalone app or widget. Google’s machine learning algorithms often work faster and more accurately at recognizing corrupt or poorly printed codes.
To take advantage of this method, open the Google search bar widget on your desktop and click on the ikon of the color lens on the right. The camera will switch to image analysis mode. Point the phone to the image. QR-The code, and the system not only reads the link, but can also provide additional information about the product, restaurant or place if the code leads to them.
One of the key features is that you can scan the codes from the gallery, and if you're sent an image with the code in the messenger, you don't have to save it and look for the scanner. Just open the photo, click on the Lens icon or the Lens icon, and the phone reads the data directly from the picture, which saves time and eliminates unnecessary actions with the files.
⚠️ Note: Google Lens can send image data to Google servers for analysis.Do not use this method to scan sensitive documents or codes containing personal data.

Scan through the Control Center and Sidebar
Shell MIUI Offers another layer of quick access integration that can be useful to Redmi owners 8T. In some versions of firmware, a shortcut to start the scanner QR-The codes are displayed in the Control Center (notification curtain) or in the sidebar (Side menu) and this allows you to start scanning without unlocking the phone completely and without looking for an application.
To check for such a possibility, lower the notification curtain down and look for an icon with an image QR-If it's not there, click on the edit button (usually a pencil icon or three dots) and look in the list of available switches. If you find the icon, drag it to the active area. Now you can scan the swipe from the top and just press it.
The sidebar is called by a swipe from the edge of the screen (left or right, depending on the settings). If you add the scanner shortcut to it, it will be accessible from any application. This is especially convenient when you are in a browser or messenger and you need to quickly read the code without interrupting the current task by switching between windows.

Comparison of scanning methods on Redmi 8T
The best way to scan depends on the situation, the quality of the code and your personal preferences. Each of the methods examined has its advantages and disadvantages. To help you determine, we have compiled a comparative table of the main characteristics of the different approaches to reading data on your device.
| Method | Launch speed | Accuracy of recognition | Additional functions |
|---|---|---|---|

| Label in the curtain | Maximum | Depends on the source. | Quick access without unlocking |
For everyday use, such as paying in a store or logging into Wi-Fi, a built-in camera is often enough. However, if you work with a lot of code or encounter poorly printed tags, Mi Scanner or Google Lens will show better results thanks to more advanced image processing algorithms.
💡
For maximum compatibility with all code types and languages, it is recommended to keep the Google Lens app installed and updated.
Why the phone can't see the code
Sometimes Redmi users 8T This is a situation where the camera is simply ignoring the QR-The first and most common cause is optical pollution. Fat spots on your fingers create a light scattering effect, and the camera can't focus on contrasting elements of the code.
The second reason could be a software failure of the camera app itself. In this case, cleaning the cache helps. Go to Settings → Apps → All apps, find Camera, select Memory, and click Clear Cache. This will not delete your photos, but reset the temporary files of the program.
Also worth checking permissions. Make sure the Scanner or Camera app has access to the camera. Sometimes, after updating the MIUI system, permissions may be reset. Go to Settings → Privacy → Permit Manager → Camera and make sure the right apps are enabled.
⚠️ Attention: If the camera has stopped focusing on any object at all and the software methods are not helping, the autofocus module or the camera plume may be damaged.
