There are lots of reasons to upgrade to iOS 13.3, but this iPhone ‘lockout’ bug is top of my list
There are lots of reasons why you might want to upgrade your iPhone with the newly released iOS 13.3 update. Maybe you are concerned about having better parental control over screen time for your kids when they are using FaceTime or Message. Perhaps the addition of support for security keys such as the YubiKey 5Ci is high on your list. Not as well reported as these feature updates, but way more important it would seem to me, is the small matter of iOS 13.3 fixing a bug that could let someone nearby lock you out of your iPhone by forcing it into an inescapable display blocking loop.
