I can’t think of a single phone that automatically opens links that are in QR codes. The worst it would do is just show a link to malware, wish you would have to manually click in order to download the malware.

I want a shirt that has a QR code that Rick rolls people.

Strongly reminds me of Old MacDonald Had a Barcode, E-I-E-I CAR. Basically put a standard anti-virus test string into various sorts of barcode and see what breaks.
