Share Wi-Fi Password via QR Code auf Realme
Sharing a Wi-Fi password as a QR code works because Realme UI stores the credentials of the network your phone is currently connected to and encodes them into a scannable image. Any camera app or QR scanner on the guest device reads that code and connects automatically, without anyone typing the password.
This function only shows up for an active connection. If your phone is connected to mobile data or a different network, the QR code option will not display the credentials you want to share.
Menu path
Open Settings ➔ Wi-Fi ➔ Menu ➔ Wi-Fi QR code. Realme UI generates the code instantly and displays it full-screen, ready to be scanned by the other device.
The guest device needs a working camera and a QR scanner, either built into the camera app or a third-party scanner app. Once scanned, it joins the network without any manual password entry.
If the other device does not support QR-based Wi-Fi joining, sharing the password as plain text or using a different transfer method is the more reliable fix.
