So, just to know what I should be doing...
The closest thing I have to hand with a QR code printed is an A4 flyer, the QR code is 20x20mm

   Does the QR code have to fill the screen?
No, in the above example, I can frame the entire flyer to fill about 3/4 of the screen, and it recognises it;  judging by the "rule-of-thirds" markers on screen, I estimate the QR code is 1/9th of the camera frame.
   Is there any indication on screen that the phone has 'seen' the QR
   code?
The phone indicates the existence of the QR code by drawing a dashed rectangle around it

   Do I actually have to 'take a picture' of the QR code?
No need to press the "shutter", the phone decodes and displays (in this case the website URL) from the flyer as a "pill" which I can click on to launch firefox.

   How steady do I have to be holding the phone?
Not especially, it tracks the QR code.
