We're facing the same problem.
Code recognition success rate on iPhone 13 and 15 models is very low (less than 10%), while on android devices, the recognition is very fast.
iPhone 13 Pro has 3 lens. And when you do a close-up scan, iPhone will automatically switch lens to make the capture clear. However, the recognition is still not happening.
iPhone 15 has two lens. When you do a very close-up scan, the image is blurred. There is no close-up lens available to make the capture clear (even with native iOS camera app). You have to keep the camera at a medium distance to make the image clear
The initial test suggests it may be more related to iOS camera & scanning library integration issues, and less a lens-switch issue
