Phone is one of my least used apps, and because Touch ID is so much better and more convenient for me I only really use my phone as an iPod for listening to podcasts nowadays as it is easier to carry between rooms. For everything else I use my iPad mini as it works how I want.
One particular example is reading notifications to scan news headlines etc., more than half the time touching the screen causes Face ID to unlock the phone and launch the app when I just want to scroll or open a group. Touch ID lets me decide when I want to unlock a device, Face ID just presumes I always want to unlock the device.
And as others have said, there are many times when I am sitting down, can see the phone on the table and reach out to unlock it to read a text message notification, except you cannot do that on a phone. Instead I have to pick it up and hold it to my face, and then if it does not work I have to enter my passcode then drag the notifications down on the home screen. If I have the iPad to hand then I can just rest my finger on the button, and even when it wants a passcode it does not go to the home screen.
Though Touch ID wants a passcode less often because it only needs it every so often as Apple requires. But Face ID constantly gets locked because of all the times it decides that any contact with the phones means I want to unlock it, so it takes the absence of a face as a security risk.
But I already know I will never buy a brand new iPhone again because of this. It is just a shame that Android is so much worse than iOS and there is no other viable competition.
If Face ID works for other people then fine, I have no problem that it is an option for them. But I never got used to it, I find it makes using my phone a poorer experience to the point I use it far less. Touch ID is good enough for Apple on my iPad, it is good enough for Apple on my MacBook. I am not the one being awkward here, the iPhone is the exception.
