Nope, works absolutely fine with cable as well. Not sure how it was in the past, but I’m not particularly missing any feature

Actually even for qr codes the pixel count (or rather camera quality) makes a huge difference. Got a new phone last year with much better camera then previous. Suddenly during presentations i didn’t need to awkwardly semi stand up and try to get closer. Just recognized the code immediately

Same for phones. But that’s the norm unfortunately
