On the iPhone, you literally just open the camera app, point it at the QR code, and a drop-down notification will prompt opening it in the browser. Thus, it is absolutely looking for one always as you describe.

And same on my mid-range 2020 Samsung. I think GGP is chasing windmills here...
Horrible experience.
It should just open the web page with zero taps if I point at a QR code in ANY camera mode, even portrait or panorama or movie or whatever the last mode I was on. I shouldn't have to tell it "I'm going to scan a QR code", it should always be looking for one, because it's computationally very, very cheap.
