iOS 12 solve a very annoying problem a Face ID through a very simple change made by the Apple company for phone users iPhone X. You have probably realized for some time that Face ID has problems and that it does not do the unlocking for iPhone X as it should, and even the Apple company recognized this in iOS 12.
Those from Apple have implemented in iOS 12 a new function that allows the reactivation of Face ID when facial recognition has failed, and we are asked for the access code for unlocking. Now iOS 12 allows us to swipe up from the bottom to retry a scan with Face ID instead of entering the passcode, but if you're still not recognized, you'll have to use it.
