iPhone XR: Face ID is not available, Try setting up Face ID later
I've just received a new iPhone XR and when I try and set up Face ID it doesn't work.
I either get an alert that says "Face ID is not available, Try setting up Face ID later"
or, it says "Move you phone lower", then "Move your phone higher".
I've tried:
• Reset all settings
• Restarting the phone
• Soft reset
• Quitting all apps
• Doing it in a well lit room
I'm currently running iOS 12.3.1
Does anyone have any advice on how I can fix it, or should I just return it as it's under warranty?
Should I try the iOS 12.4 beta?
Thank you
iPhone XR, iOS 12
