One such useful option is the ability to instantly connect to a wireless network. Wi-Fi By scanning a special QR code, you no longer have to manually enter long, complex passwords or dictate them to guests, risking typing errors.
This process is intuitive, but owners of different models may encounter slight differences in the shell interface. EMUI or HarmonyOSIn this article, we'll cover in detail how to activate the scanner, where to find it in system settings, and what to do if the standard camera doesn't recognize the code. You'll also learn how to use the system's built-in tools for quick internet access.
It's worth noting that connection security remains a priority, so the system may prompt you to confirm your actions before saving new network settings. Understanding the module's operating principles NFC Understanding the camera in this context will help you avoid common mistakes. Let's look at the available connection activation methods step by step.
Preparing the device for scanning
Before you start scanning directly, you need to make sure that your smartphone is Huawei Ready to work with wireless networks. First, check that Wi-Fi is enabled in the system settings. Even if you plan to scan a code for a new network, the radio must be active to process the request correctly.
It is also important to ensure that the device's camera is functioning properly and the lens is clean and free of dirt. Defocusing Dust or dirt on the lens may prevent the code from being read on the first try. Wipe the camera with a soft cloth before starting the process.
Make sure you have access to the QR code itself. It could be displayed on another device's screen, printed on a sticker on the router, or in your image gallery. The code must be clear, contrasting and undamaged., otherwise the system will not be able to decode the data string encrypted in it.
Using the built-in scanner in the Camera app
The fastest way to connect to the network on most modern models Huawei — This is using the standard Camera app. The company's engineers have integrated QR code recognition directly into the viewfinder, eliminating the need for third-party apps.
Launch the Camera app and point the lens at the code. The system will automatically analyze the image. If a link or connection information appears in the frame, a notification will pop up on the screen. Simply tap it to initiate the connection.
- 📷 Open the Camera app from your home screen.
- 🎯 Point the lens at the QR code, holding the phone at a distance of 10-15 cm.
- 🔗 Wait for the yellow frame or pop-up notification to appear.
- ✅ Click "Connect" in the pop-up window.
In some firmware versions EMUI The scanning function must be activated manually. To do this, in camera mode, tap the icon with four squares or the "AI" icon in the upper corner, then select "Scanner" mode. After this, hovering over the code will instantly scan the data.
⚠️ Attention: If the camera focuses but doesn't offer any actions, check that "QR code recognition" is enabled in the camera settings. In older software versions, it may have been disabled by default.
Connecting via the Wi-Fi settings menu
An alternative and often more reliable method is to use the built-in scanner directly in the wireless networks menu. This is especially useful if the camera is not working properly or you want to immediately see a list of available networks for comparison.
To get started, go to the section Settings and select the item Wi-FiIn the menu that opens, usually in the upper right corner or at the bottom of the screen, there's a special scanner icon. It looks like a square with lines inside it, or a camera icon.
By clicking this icon, you activate the scanning mode optimized specifically for network configurations. After reading the code, the phone will automatically insert SSID Enter your network and password in the appropriate fields. All you have to do is confirm the connection by clicking "Connect."
☑️ Connection algorithm via settings
This method ensures that received data is processed by the system network manager, reducing the likelihood of encryption compatibility errors. This is especially useful for corporate networks or networks with complex security parameters. WPA3.
Scanning the code from the image gallery
It often happens that a QR code is sent to you via messenger or saved as a screenshot, and it's impossible to physically point the camera at it. In this case, the scanning function from the gallery, which is available on smartphones, comes to the rescue. Huawei with shell EMUI 10 and newer.
Open the image with the code in the Gallery app. Tap the "More" button (usually the three dots or "See More") and select "Recognize" or "Scan QR Code." The system will analyze the image and offer actions similar to those performed when scanning with a camera.
- 🖼️ Open the desired image in the gallery.
- 🔍 Press the menu button or "More".
- 📡 Select "Recognize QR code".
- 🔐 Confirm connection to the detected network.
If the standard gallery doesn't see the code, you can use the service Google Lens (Google Lens), which is integrated into many system apps. Simply open a photo in Google Photos and tap the Lens icon—it will easily retrieve the connection data.
Why isn't the code read from the gallery?
If the image is heavily compressed, has a low resolution, or the code is corrupted by compression artifacts, the algorithm may not recognize the structure. Try zooming in on the image before scanning or requesting the original file.
Using Control Center and Widgets
In the latest versions of the operating system HarmonyOS and updated EMUI The scanner is now easily accessible via the Control Center. Swipe down from the top right corner of the screen to open the quick access panel.
Here you'll find a "Scanner" widget or icon that allows you to quickly add a device. This is especially handy when you need to quickly share your internet connection or connect to a guest network without having to delve into the settings menu.
You can also add a scanner widget to your home screen. To do this, tap and hold an empty area of the screen, select "Widgets," and find the corresponding tool. This will create a shortcut that immediately launches the camera in code scanning mode.
