On Thursday, Apple published the iPadOS 17.4.1 update, which fixes a bug that can make it impossible for some iPads to scan QR codes.
According to an Apple Support document, a flaw in iOS 17.4 affected the camera on the sixth-generation iPad, seventh-generation iPad, 10.5-inch iPad Pro, and second-generation 12.9-inch iPad Pro, making it impossible for camera apps to scan QR codes. Apple advises users experiencing this issue to update to iPadOS 17.4.1 to resolve it.
Before iPadOS 17.4.1, Apple advised iPad users to use the Control Center’s Code Scanner feature if they needed help to scan QR codes with the Camera app or other third-party apps.
Because only a few iPad models are affected, Apple did not provide information on the problem patch in its release notes. Further undisclosed bug fixes and security enhancements were incorporated into iPadOS 17.4.1.
