We’re running into an issue scanning QR codes on iOS using the Barcode Reader control in a Canvas App.
- When we scan the same QR code using the native iOS Camera app, it works immediately.
- In our Power Apps Canvas app, the Barcode Reader control does not detect the code.
- We’ve already tried adjusting scan modes and image quality, but behavior stays the same.
- We´ve already tried different smartphones
What seems to matter is the QR code’s background / quiet zone:
- A QR code without a white border (quiet zone) is not recognized by the Power Apps control.
- As soon as we add a white border around the QR code, the scan works reliably.
- Since the iOS Camera can scan the QR code even without the border, this looks like a limitation/issue with the Power Apps Barcode Reader control rather than the QR code itself.
(See attached image showing the QR code versions with/without the white border.)
Has anyone seen this before, know if it’s a known issue, or have any recommended workarounds/settings to improve detection in the Power Apps control on iOS?
