There is no reason to autocorrect a QR code scan. QR codes come with built-in error correction, so there’s a vanishingly small chance of a successfully-scanned QR code containing an error. It seems like Camera here might be treating QR code URLs as manually entered URLs or OCRed URLs and applying autocorrection logic.

Single char differences in qr code input tend to be huge. This can only be explained by the QR result getting passed through a pipeline intended for OCR results. An almost depressingly boring explanation. It kind of seems like something that would likely happen in big organisations from disconnect between those deciding and those with their fingers in the code, but it could also happen to a solo.
- zapdrive 5y agoIt is more likely trying to autocorrect the url entred during the QR code creation process. Which is stupid. Don't people usually test their QR codes after printing?

- iSnow 5y agoFrom the article, it seems this is simply a side-effect of some changes in mobile chrome that spilled over into the camera-app
