Hmm, yes, I did not try these but I have noticed that my default phone app in my S22 is freakishly fast at detecting QR codes, something I never remember that zxing was. Does anyone know if these are today implemented in neural networks or something? Specialized hardware? Or just very well optimized. Sometimes it feels like only 1 frame in the camera is enough, and distance, angle, lighting and focus is not important.
