My 15 pro max is my 4th iPhone with faceID, and I still miss a fingerprint sensor very very often. FaceID is fantastic for the moments where it works, but there are enough moments where it just does not cut it.
The problem is that one of those moments where it simply doesn't work for me is straight up dangerous: having to unlock to enable carplay, while I'm in my car behind the wheel. Just picking up my phone in that situation is illegal where I live, but no, I need to hold it in front of my face before it wants to unlock.
That's probably the worst situation, but just having my phone on my desk, wanting to glance quickly at new notifications never works. Sometimes, on the lock-screen it doesn't unlock to view the notifications unless I swipe up. And if I by accident swipe up from a bit too low down on the screen, it unlocks completely instead of showing me my notification previews.
