But I wonder — if it was feasible to implement Touch ID under the screen, would they have done it or not? Was FaceID the mechanism they always wanted, or was it the only one they could practically implement on an edge-to-edge display?
From all the previous rumors and rumor sources since the beginning of the year, it seems clear that Apple originally wanted an under-display TouchId solution. It just wasn't ready in time.
I think it's impressive that Apple had Face Id as a backup solution in their pocket, even if it was originally just going to be a secondary choice (or not included at all).
Bet there was a lot of sleepless nights for the Face Id team recently
