Xiaomi’s modern smartphones have become universal tools that can replace many individual gadgets, and one of the most popular features is the ability to instantly read two-dimensional hatchings, known as “Steve-Steve-Steve-Steve-Steve-Steve-Steve-Steve-Steve-Steve-Steve-Steve-Steep” (DDDDDDDDD) QR-Users often face the need to quickly access a Wi-Fi network, download an application or confirm login to an account without wasting time searching for third-party software.
Owners of Android devices with MIUI or the new HyperOS can take advantage of the built-in features of the system. You do not need to download dubious programs from unverified sources, since the necessary functionality is already integrated into the standard interface components, which ensures a high level of security and privacy of your data when scanning.
In this article, we will take a look at all the available methods for activating the scanner. We will look at the settings of the built-in Camera application, the capabilities of the system scanner and working with desktop widgets. Understanding these nuances will allow you to maximize the potential of your Redmi or POCO in everyday life.
Built-in scanning function in the Camera app
The fastest and most obvious way to read code is to use a standard photo application. Xiaomi engineers have long implemented pattern recognition algorithms directly into the camera software, a solution that works on most current models, from the budget Redmi Note series to the flagship Mi.
To activate the function, you need to open the Camera app and carefully examine the viewfinder interface. At the top of the screen or in the side menu, there is often an icon resembling a square with dots inside or the Google Lens logo. If there is no such icon explicitly, try clicking on the three horizontal bars in the corner of the screen to reveal the additional settings menu.
⚠️ Note: Some global versions of the firmware MIUI If you don't see the scan option, go to the camera settings (cogs) and find "Code Scanner" or "Google Lens" to force it to activate. After you turn on the mode, point the lens at the image. The system automatically defines the boundaries of the code and suggests action: open a link, copy text or connect to the network. It is important to keep the device stable so that the camera can focus, especially in low light. 💡To improve focus when scanning in the dark, tap the screen in the code area so that the camera rearranges exposure and sharpness.Using the Scanner system app Unlike many other manufacturers, Xiaomi provides a separate system app called the Scanner. It has advanced functionality compared to a conventional camera and allows you to recognize not only the camera. QR-You can find codes, but also documents, products in stores, and even translate text in real time, and you can find it in the Tools folder on your desktop or through a global search. The application interface is divided into tabs, which makes navigation intuitive. When you start up, you immediately open the viewfinder, ready to go, and you have mode switches at the bottom, and one of the key features of this tool is that you can scan the images you've saved in the gallery. If you have a screenshot of the code or a photo from the messenger, you don't have to send the file to another phone, just select "Image" in the scanner interface and specify the path to the file in the device's memory. ☑️ Check scanner Open App Scanner:Allow access to camera:Him to bright code:Check system response: 0 / 1 Setting up the Scanner widget on the desktop for those who use QR-The best solution is to bring the function to the home screen, and the Widget Scanner allows you to start the recognition process with one touch, bypassing the search in the application menu, which is especially convenient when you need to quickly pay for a purchase or present a pass. To add a widget, pinch your two fingers across your desktop to enter edit mode, or press the menu button (usually three dots or swipe to the right). Select the "Widgets" section and find the "Scanner" item in the list. Drag it to the free screen space. The size of the widget can be changed by stretching its boundaries. Some versions of the shells allow you to customize the appearance of the icon, choosing between a minimalist logo or a button with a signature. 📊 What kind of scan do you use more often?Integrated camera:Separate application Scanner:Third-party programs:Do not use QR-Google Ecosystem offers its powerful tools for working with visual information. Google Lens service is deeply integrated into Android and often runs even faster than the manufacturer's native solutions. It's available through the Google Search widget on your desktop or through the Google Photos app. If you look at an image in a gallery and see the code on it, the system itself can offer the option "Search by Image" or "Lens". Clicking on this button will trigger a picture analysis, and the phone will highlight the area with the code, suggesting that you click on the link, which eliminates the need to take a screenshot and open a separate application, and it is worth mentioning the possibility of using a voice assistant. Say the phrase, OK Google, scan it. QR-code, you can run the appropriate mode if it is supported by your firmware version and language settings, but manual widget launch is still a more reliable option. Startup Speed Requirements Application Camera High Basic (links, Wi-Fi) Internet availability for links System Scanner Average Extended (goods, translation) Memory of Google Lens Device High Maximum (AI-Analysis of Google Widget Instant Depends on the settings of the place on the screen Solution: why the camera does not see the code Despite advanced technology, users sometimes face situations when the smartphone stubbornly refuses to respond to the code. Most often, the problem is physical obstacles: a contaminated camera lens creates a soapy image effect, which makes it impossible for algorithms to read contrast points. Another common cause is insufficient lighting or glare. The glossy surface of the screen on which the code is displayed can reflect the light of the lamps, creating a white spot instead of black modules. Try changing the angle of the phone relative to the light source or the source screen. ⚠️ Note: If the code is corrupted, taped or printed at low resolution, the software may not recognize the structure. In such cases, manual data entry (if duplicated by text) will be the only way out. Go to Settings. → Annexes → All applications → Scanner (or Camera) → Permissions. Make sure that the camera is allowed. Sometimes, after the system update, security settings are reset, blocking the functions. MIUI There was a hidden test mode. QCQR, which can be activated through the engineering menu. However, in modern versions of HyperOS, this path is closed for security reasons, and you should rely only on standard methods. QR-There are risks, not only in terms of convenience, but also in terms of code, where attackers can create codes that lead to phishing sites that mimic bank or social media pages, and the main danger is that the person does not see the real address of the link until the moment they click. Modern versions of Android and browsers such as Chrome or MIUI Browser, they have built-in security mechanisms, they analyze the link and warn the user if the site is marked as dangerous, but rely on automatic protection alone. Always read the pop-up notification carefully before you click. If the code promises a win, a discount or requires the entry of card data - be extremely vigilant. It is better to enter the address of the site manually than to click on a suspicious link. 💡The main rule of digital hygiene: never enter confidential data (passwords, CVV maps) on pages opened through QR-If you're not 100% sure of the source, can you scan it? QR-Yes, the process of reading and decoding information is locally on your phone's processor and does not require internet access, but if the code contains a link to a website, you will need a network connection to open the page. Text codes or contacts work offline. Why doesn't my Xiaomi have the Scanner app? Some global firmware versions (Global) ROM) The system scanner can be replaced by integration with Google Lens or hidden in the tool folder. Try searching by settings by entering the word "Scanner" to find and activate the component. Is it safe to use third-party apps from the Play Market? Use of third-party apps is only justified if the usual methods do not work. Popular applications from well-known developers (for example, Kaspersky QR Scanner) are safe. However, avoid little-known programs that require excessive permissions, such as access to contacts or calls. How to turn off the scanning sound? The sound of successful reading is often annoying in quiet places. To remove it, open the settings of the Camera or Scanner application itself. There must be a "Scanning Sound Effects" item that can be deactivated from the Internet interface, if the code is not being accessed from the old one, or the code is running the code from the server. If the problem is not solved, contact the sender of the code to clarify the information, as technically you can not fix anything.
