How do you add/delete learned QR/NFC after adding one?


#1

When I tap on QR Code or NFC in an alarm after setting up a learned code, I am not able to access the dialog with the delete/“Learn” buttons and it seems the only way to add/delete learned QR/NFC codes is to either clear the data for Sleep as Android or uninstall/reinstall it.


#2

To get back to the QR code/NFC settings, do the following:

  • go to Settings > Captcha and set NFC/QR as the default captcha
  • a Settings option will show up, which will take you to the specific captcha settings
