Contrast and size still matter more than decoration
Low contrast, tiny print size, glossy surfaces, and logos that cover too much of the pattern all reduce scan reliability. These are boring problems, but they cause a large share of “broken QR” complaints.
What to do next
Recreate the code with a shorter payload, higher contrast, and realistic sizing. Then test on at least one older phone before publishing it widely.
