Modern smartphones such as Honor 9, are equipped with powerful tools to simplify the user's life, and one of the most useful is the ability to quickly connect to a wireless network. Instead of manually entering a complex password consisting of dozens of characters, you simply point the camera at a special code. This feature is especially useful when you need to connect guests or a new device to your network and don't want to type out long character combinations.
However, despite the fact that Android has supported native QR code scanning for several years now, on devices Huawei And Honor with shell EMUI or Magic UI This process can have its own nuances. Users often encounter problems with the standard camera not recognizing the code immediately, or they don't understand where to find the scanner function in the system. In this article, we'll cover all the ways to activate this function on your phone.
We'll cover not only the system's built-in tools but also alternative methods that are guaranteed to work even if the basic settings have been changed. You'll learn how to create your own access code and what to do if your phone recognizes the code but won't connect to the network. Important: For the camera scanning feature to work without third-party apps, you must have Android version 10 or higher or Google Lens installed.
Honor 9's built-in camera capabilities for scanning codes
The first place an owner should look Honor 9, is the default Camera app. The company's engineers have integrated image recognition algorithms directly into the viewfinder, allowing data to be read without launching additional software. To activate this feature, open the app and carefully inspect the interface. Some firmware versions require switching to a special mode.
Users often simply point the camera at the code, unaware that this feature can be disabled in the settings. If nothing happens when you hover over the QR code and no notification appears, check the top bar or camera settings menu. There may be an icon resembling a square with dots inside, or a "QR code scanning" option. Enable it by sliding the slider to the "On" position.
It is worth noting that on older versions of the shell EMUI The scanner may be in a separate application or in the "Tools" folder. If scanning isn't working in the camera, try finding the "Scanner" icon on your desktop. This is a system application that uses the same OCR libraries but offers more advanced functionality for working with documents and text.
Recognition quality directly depends on lighting and focal length. Camera Honor 9 The camera has excellent optics, but in low light, the autofocus can be shaky. In this case, it's best to turn on the flash or illuminate the code area with an additional light source. Also, make sure the code is centered in the frame and takes up a significant portion of the screen.
Using Google Lens
If built-in tools fail for some reason, the ecosystem comes to the rescue GoogleOn most smartphones HonorFor devices with Google services, the Google Lens app is either integrated into the search bar or available as a standalone app. It's a powerful computer vision tool that's excellent at reading QR codes of any format.
To use this method, open the Google search bar widget on your desktop or launch the Google app. To the right of the search bar, you'll see a camera icon. Tapping it will launch Lens mode. Then, simply point the camera at the Wi-Fi code. The system will automatically recognize the data type and prompt you to connect to the network.
- 📸 Open the Google app or search widget on your home screen.
- 👁️ Click on the camera icon (Google Lens) to the right of the search bar.
- 📡 Point the lens at the network's QR code and wait for recognition.
- 🔗 Tap on the "Connect to Wi-Fi" pop-up notification.
Advantage of using Google Lens lies in its universality. It does not depend on the shell version. Magic UI or EMUI and works stably on any AndroidFurthermore, if the code is damaged or poorly printed, Google's algorithms are often able to read it where a standard camera would fail. This makes this method the most reliable for complex cases.
⚠️ Please note: Google Lens requires an active internet connection (mobile data or an already connected Wi-Fi) to work, as image processing may occur on Google servers.
Third-party scanner apps from the Play Market
When the built-in solutions aren't working or aren't working correctly, you can always turn to third-party developers. Google Play There are many QR code scanning apps available, often with advanced features such as scan history, code generation, and automatic connection without any confirmations.
Popular options include: QR Code Reader from Scan or Binary EyeThese apps are lightweight and don't require any special permissions other than camera access. After installation, simply launch the app, and it will immediately switch to viewfinder mode. When a Wi-Fi code is detected, the app will prompt you to connect.
Using third-party software offers another advantage: history. You can go back at any time and see which networks you've previously connected to, for example, if you forgot your home network password but once scanned the login code. This is convenient for system administrators or cafe owners who frequently change access settings.
However, be careful when choosing an app. Many free scanners are overloaded with ads or request excessive permissions to access contacts and geolocation. Choose apps with high ratings and numerous reviews to avoid compromising your security.
Why do some applications require internet access?
Scanners may request network access to verify the security of a link contained in a QR code or to display in-app ads. Internet access is not required for a simple Wi-Fi connection, unless the code leads to a website with a captive portal (login page).
Step-by-step instructions for connecting to Wi-Fi via QR code
Now let's move on to the actual steps. For a successful process, it's important to follow the steps in sequence. Small deviations, such as hand shaking or glare on the screen, can cause reading errors, so follow the instructions carefully.
☑️ Connection checklist
First, make sure that the Wi-Fi module on your Honor 9 Enabled. While modern systems can enable it automatically during scanning, it's best to prepare your device in advance. Open the notification shade and enable wireless networks. Then launch your chosen scanning method (camera, Google Lens, or an app).
Point the lens at the code so it fits completely within the frame. Hold the phone steady. Once the code is recognized, a bar with the network name (SSID) will appear on the screen. Tap it. The system will ask for connection confirmation. Once approved, the phone will automatically enter the password and authenticate to the network.
The table below lists the possible statuses you may see during the connection process and their meaning:
| Status on screen | Description of action | Necessary actions |
|---|---|---|
| Obtaining an IP address | The phone is exchanging data with the router | Wait 5-10 seconds |
| Saved | The password is correct, connection successful. | There is no need to do anything |
| Authentication error | Incorrect password or encryption type | Check the code or enter it manually |
| Getting an IP address... (long) | Problem with router's DHCP server | Reboot the router |
If the connection is successful, a Wi-Fi icon will appear in the status bar. You can now use the internet.
How to create a Wi-Fi QR code for sharing from your phone
Often the opposite situation arises: you are the owner of the network and want guests to be able to connect to your Wi-Fi on Honor 9 or any other device by simply scanning the code. You can generate this code directly in your smartphone's settings, without using third-party generator sites.
To do this, go to the settings menu and select the section Wi-FiFind the network you're currently connected to (or sharing) and tap the gear icon or arrow next to its name. In the menu that opens, look for the "Share" button or the QR code icon. The system will generate an image containing all the necessary connection information.
This method is convenient because you don't need to dictate or enter a password. The guest simply points the camera, and their device instantly gains access. This is especially useful in offices or meetings where many devices need to be connected to the network in a short period of time. You can even take a screenshot of this code and send it to friends via instant messaging.
⚠️ Please note: The QR code generated in your Wi-Fi settings contains your password in plain text. Do not post screenshots of it in public places or on social media if you don't want your neighbors using your internet connection.
Troubleshooting scanning problems and errors
Despite the simplicity of the technology, users Honor 9 You may encounter difficulties. Sometimes the phone simply ignores the code, or the connection succeeds, but the internet doesn't work. Most often, the problem lies in security settings or hardware issues.
One common cause is an outdated encryption protocol. If your router is configured to use an older security standard (such as WEP), and your phone is attempting to use a more modern one, automatic connection may fail. In such cases, the system may prompt you to enter the settings manually.
- 🚫 The code is unreadable: Increase the distance to the code or, conversely, move the phone closer. Check the lens is clean.
- 🔒 Password error: Make sure the QR code is up to date. If you changed the password on your router, the old code will no longer work.
- 📶 No internet after connecting: Check if the network requires browser authentication (Captive Portal). This is common in cafes and hotels.
It's also worth considering that some corporate networks use complex security certificates that can't be transmitted via a simple QR code. In this case, you'll need to contact your system administrator for custom settings. While such issues are rare for home networks, they can occur if you have specific router settings.
If you have updated the firmware on Honor 9 and the function stopped working, try resetting the network settings. Go to Settings → System & updates → Reset → Reset network settingsThis action will delete saved Wi-Fi passwords and Bluetooth settings, but often resolves software conflicts.
Why can't the Honor 9 see a QR code that another phone can read?
This could be related to different software. If a specialized app with improved decoding algorithms is installed on the other phone, it may be able to read corrupted codes. The issue could also be with the focal length of the Honor 9 camera—try adjusting the camera angle.
Is it possible to connect to 5GHz Wi-Fi via QR code?
Yes, the QR code only contains the network name (SSID) and password. The frequency range (2.4 GHz or 5 GHz) is determined by the router and the phone's module. If your Honor 9 supports 5 GHz and the network is broadcast, the connection will be successful.
Is it safe to scan QR codes from unknown sources?
Scanning a Wi-Fi connection code is safe, as it only contains the connection details. However, if the code leads to a website (URL), always check the address before clicking. Scammers can use codes for phishing purposes.
What should I do if after scanning my phone says "Unable to obtain IP address"?
Try rebooting your router. You can also try changing the IP settings from DHCP to Static in your phone's Wi-Fi settings and manually entering the address if you know your network settings.
Does this method work on Honor 9 without Google services?
Yes, it works. The built-in camera and system scanner in EMUI/Magic UI work regardless of Google services. Google Lens will be unavailable, but the built-in tools will work.
