⚠️ Attention: On some models, the feature may be hidden in deep settings. If you don't find it in the standard Wi-Fi menu, try using Bixby Vision (we will talk about it below).

Where can I get a QR code to connect to Wi-Fi?

There are several ways to obtain a QR code for connecting to a network. The easiest is to generate one yourself on another device already connected to the network. Here are the main sources:

• 🔄 Smartphone or tablet: Use apps like QR Code Generator or built-in functions (for example, in iPhone You can generate a code in your Wi-Fi settings).
• 💻 Computer: Sites like qi-fi.org or qrcode-monkey.com allow you to create a code by specifying the network name and password.
• 📡 Router: Some modern routers (eg. ASUS, TP-Link) generate a QR code directly on the sticker or in the web interface.

Turn on Wi-Fi in Settings

Check the lighting - the code should be clearly visible

Place the code on a flat surface-->

⚠️ Attention: If the QR code is generated for a network with hidden SSID (invisible network), your smartphone may not recognize it automatically. In this case, you'll have to enter the network name manually after scanning.

Alternative connection methods via QR code

If the standard method doesn't work, try alternative options. They may be useful if:

• Your firmware does not have a built-in scanner in the Wi-Fi settings.

1. Open the app Camera.
2. Click on the icon Bixby Vision (eye in a circle).
3. Select mode QR code.
4. Point the camera at the code and wait for recognition.
5. Tap the notification about the found Wi-Fi network.

2. Third-party applications

If the built-in tools don't work, install one of these applications:

• 📱 QR & Barcode Scanner (from Gamma Play) - light and fast.
• 📱 WiFi QR Connect — specializes in networks.
• 📱 Google Lens — recognizes codes and offers to connect.

Once installed, open the app, scan the code and follow the on-screen instructions.

What to do if Samsung doesn't recognize the QR code

Sometimes users encounter problems with their smartphones refusing to scan the code or connecting to the network. Here are the most common causes and solutions:

If none of the methods helped, try reset network settings:

1. Go to Settings → General Management → Reset → Reset Network Settings.

3. Restart your phone and try scanning the code again.

⚠️ Attention: Resetting your network will delete all saved Wi-Fi and Bluetooth device passwords. Write down important information beforehand.

Security: Risks of QR Code Connection

While QR code connection is convenient, it's not without risks. Attackers can create fake codes to:

• 🔍 Intercept traffic: Connect you to a fake network and steal data.
• 📡 Redirect to phishing: Replace the legitimate code with your own, which leads to a fraudulent site.
• 🔑 Steal password: If the code is generated on an infected device.

To minimize risks:

• 🛡️ Check the source of the code: Do not scan codes from suspicious websites or stickers.
• 🔒 Use a VPN: For example, Samsung Secure Wi-Fi (built in One UI).
• 📵 Disable auto-connection: In the Wi-Fi settings, disable the option Auto-connection to open networks.

QR codes for corporate networks (with WPA2-Enterprise) may contain authentication data that attackers can use to attack the entire infrastructure. Never share such codes in public chats or on social media.

My Samsung doesn't see the QR code scanning option in the Wi-Fi settings. What should I do?

If you have an older model or outdated firmware, try:

1. Refresh One UI through Settings → Software Update.
2. Use Bixby Vision or Google Lens.

Is it possible to connect to a hidden network (with a hidden SSID) via QR code?

Technically yes, but not all scanners support this. If the code is generated for a hidden network, after scanning it:

1. Enter the network name (SSID) manually.
2. Confirm the connection.

If your smartphone does not prompt you to enter SSID, this means the scanner did not recognize the hidden network - try another method.

There is a risk, but it can be minimized:

• Do not connect to networks with suspicious names (for example, Free_WiFi_Hack).
• Use VPN to encrypt traffic.
• Disable automatic connection to open networks.

If the network requires additional authentication (for example, through a portal), a QR code will only simplify connection, but will not protect against fraud.

How to know if a Wi-Fi QR code is fake?

Signs of a fake code:

• The network has a name similar to the legitimate one, but with typos (for example, Starbucks_Free instead of Starbucks_WiFi).
• The code is posted on suspicious websites or stickers without the establishment's logo.
• After connecting, a website opens asking you to enter personal information.

• 📱 Make sure your screen brightness is at maximum.
• 🔍 Keep devices 10-15 cm apart.
• 🌞 Avoid glare - it's better to scan in the shade.

If the code is not recognized, try taking a screenshot and showing it from another device.
