> TouchID was removed because it took up space on the front of the phone and Apple wanted the screen to be bigger. There's no deeper reason than that.
The Pixel handset has the fingerprint sensor on the back of the phone. It appears to work quite well. Much of this needless outrage could be obviated by allowing multiple simultaneous biometrics for auth; while taking the phone out of your pocket, place your finger on the sensor to initiate FaceID.
I confess, never in my years of phone ownership have I had that specific use case, or considered that it might be important for others. Do you find yourself doing that often? If so, can I ask what for?
Second, facial features are more unique than fingerprints - according to apple's own presentation, there's a 1 in 10.000 chance that prints from different people would unlock it. With face ID, this becomes 1 in 50.000 (iirc).
> Will Apple continue progress and built in PinchID - a tiny needle that sting you to test if you are you based on your blood/DNA?
I struggle to believe you when you say that's a serious question...
> Im also concerned about the data Apple will collect.
The FaceID data will be stored in the secure enclave locally on your phone, just like TouchID data was. Apple will not collect it.
