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.
