I'm trying to override the problem of connecting to web whatsapp on a phone without a camera in order to scan the QR code. It's probably not important but the computer runs linux.
My idea: creating a virtual device that the phone (samsung galaxy s21) will see as a camera, and in this camera there will be:
Option 1: the remote controlled desktop of the linux computer (by vnc or similar).
Option 2: the android phone will be connected by USB to the computer and it will see the desktop as a "camera".
Any other idea can be good, but it must be a synchronized whatsapp and not on an android emulator.
Thanks!
