How do you count? QR-Android code Xiaomi: full guide

Modern smartphones have become universal tools for interacting with the world, and Xiaomi is no exception. Owners of these devices often face the need to quickly read information from a label, whether it is payment in a store, connecting to Wi-Fi or clicking on a link. However, the standard interface of the shell MIUI or HyperOS does not always make this feature obvious to the beginner.

Unlike some other vendors, the Android system on Redmi and POCO devices may require pre-activation of the built-in scanner.This is done to protect against accidental clicks on malicious links, but often creates inconvenience. You do not need to download third-party apps if you know where to look for the desired option.

In this guide, we will look at all the existing ways of reading two-dimensional barcodes on smartphones of the Chinese brand.We will look at the settings of the system camera, desktop widgets and even hidden features that not all users know about.

Built-in functionality of the system camera

The fastest and most obvious way is to use the standard Camera app, and Xiaomi engineers have integrated recognition algorithms directly into the viewfinder, but by default, this option is often disabled. To activate it, launch the app and find the dot square icon or the words "AI" in the top corner of the screen.

You click on this item and you open an AI menu, and you select Scanner or QR mode, and then the lens automatically focuses on the codes, and the information you read will appear in the pop-up window, and if the code contains a link, the system will suggest you click on it, and if the text will copy it to the clipboard.

It's worth noting that the mode of operation depends on the version of the shell. In older versions of MIUI, the scanner could be brought into a separate application, whereas in HyperOS, it is deeply integrated into the image processing algorithms. If automatic recognition does not work, try bringing the phone closer or provide better lighting.

⚠️ Warning: Do not point the camera at suspicious codes from unknown sources, unlike text links, visually assess security QR-code is not possible and it can lead to a phishing site.

Using the built-in scanner saves battery power, as it does not require the launch of heavy third-party programs, and the system module has a higher priority in working with the hardware, which provides instant response.

Setting up the “Scanner” widget on the desktop

For those who scan codes constantly, opening the camera and searching for mode can be inconvenient. The MIUI shell allows you to put a separate widget directly onto the main screen, which greatly speeds up the process and makes the function available in one click.

To add a widget, press the empty space on your desktop or pinch your two fingers to go into edit mode. In the bottom menu, select "Widgets" (or "Add widgets"). In the list, find the "Tools" category or immediately look for an item called "Scanner".

Once you add a widget to the screen, you can start the scanner instantly, which is especially useful on large-diagonal devices, where it takes a long time to reach the top of the screen, and the widget can also display the history of recent scans, if this feature is supported by your firmware version.

It's important to understand the difference between a scanner widget and an app shortcut. A widget is an interactive element that can have its own interface, whereas a shortcut simply opens the program. In the Xiaomi ecosystem, a native widget is more stable and faster.

Use of Google Lens (Google Lens)

If the built-in tools don't work well or are not working well, Google Lens comes to the rescue, and it's built into most Android smartphones and is often part of the Google or Google Photos app, and the search giant's algorithms often do better at corrupting or complex codes.

You can run Google Lens through Google's desktop search bar or through the camera app if it supports integration. Click on the square camera icon. Point the lens over the code, and the system automatically recognizes it and suggests actions: open a link, add a contact or find a product.

The advantage of this method is cross-platform, because if you're used to Google's interface on other devices, you don't have to relearn, and Google Lens can translate text into codes in real time, which can be useful when scanning foreign products.

Google Lens requires a stable Internet connection, as image processing often takes place on the company’s servers, which is worth considering if you are in a low-reception zone.

Scanner in the Security app

The unique feature of Xiaomi, Redmi and POCO smartphones is the system application Security, which combines antivirus, memory cleanup and other utilities, and it also has a powerful code scanner inside it that users often ignore.

To find it, open the Security app (green shield icon). scroll down to the Tools section or look for the Scanner icon. This module is especially good because it checks a read link to viruses before you go, using antivirus databases.

Using a Security scanner is the most reliable way to work with unknown codes, and the system will alert you if a link leads to a site with malware or is known to be fraudulent, a critical feature for protecting personal data.

In some regions, this tool may be called "Mi Scan" or integrated into the Mi Browser browser, and the logic remains the same: maximum security and check content before performing actions.

Comparison of scanning methods on Xiaomi

The variety of ways can confuse the inexperienced user, so what method to choose in a particular situation? Let's look at the advantages and disadvantages of each approach, so you can decide on a strategy for using it.

The built-in camera is ideal for everyday tasks: menus in a restaurant, links to sites. The desktop widget is suitable for those who work with codes constantly, for example, couriers or storekeepers. Google Lens is indispensable for text and translation, and the scanner from Security is the best choice for checking suspicious tags.

The choice of a specific tool depends on your priorities: speed or safety. In everyday life, a standard camera is often enough, but the availability of alternatives in the arsenal of the Xiaomi user is a great advantage.

Problem Solving and Frequent Errors

Even on modern devices, there are occasional crashes: the camera may not focus, the scanner may not see the code, most often the problem is lens contamination or the wrong distance, wipe the camera with a soft cloth and try to change the distance to the object.

If the code is damaged or printed on a glossy surface, there may be glare that interferes with reading. Try changing the angle of the phone. Also make sure that the camera resolution settings do not select exotic aspect ratios that can cut the scan area.

💡

If the camera is not focusing on the code, tap the screen in the code area to force the focus and exposure to be blocked.

In rare cases, cleaning the Camera app cache helps. To do this, go to Settings → Apps → All Apps → Camera → Memory and click Clear Cache. This will not delete your photos, but reset temporary program files.

If nothing works, check for system updates. Xiaomi engineers regularly release patches that improve computer vision algorithms. The current version of MIUI or HyperOS guarantees better compatibility with new types of code.
