• 🔹 QR & Barcode Scanner (from Gamma Play) - supports Wi-Fi QR codes and works without the Internet.
• 🔹 WiFi Key Recovery — additionally displays saved passwords (requires root rights).
• 🔹 Barcode Scanner (from ZXing Team) - open source, no fluff.

After installation, open the application, scan the code and confirm the connection in the system dialog box.

4. Solving common scanning errors

If the QR code does not scan or connection errors occur, please check the following:

On Samsung Galaxy models with the Exynos 9820 chip (e.g., the European version of the S10), an "Authentication..." error may occur when connecting to WPA3 networks. Solution: Temporarily switch your router to WPA2 or update your firmware to One UI 5.0+.
