I've encountered a consistent issue with iOS NFC Core UI where the app's user interface becomes unresponsive or visually distorted after scanning an NFC tag in landscape mode, dismissing the NFC UI, and then attempting to scan in portrait mode. Steps to Reproduce: Open an NFC-enabled app that uses iOS NFC Core UI. Start an NFC scan while holding the device in landscape mode. Dismiss the NFC scanning UI. Switch the device to portrait mode and initiate another NFC scan. Observe the UI, which often appears distorted or becomes unresponsive.
NFC Core UI Issue: UI Becomes Unresponsive After Switching Between Landscape and Portrait Modes
This sounds like it could be an issue with the system's NFC UI, and we would like you to file a bug report about this.
Don't forget to include as much information as you can about the cases you see this problem with. In your case a video or images showing the distortion would be very helpful.
To file a bug report, you can use the Feedback Assistant.
Once you open the bug report, please post the FB number here for my reference.
