Unfortunately no (unless thats a new unannounced feature in this installment) They help/follow you around during missions like a buddy/partner. That said, they have different armors and their own “character creator” so you can customize and dress up your own lil guy.
Yep. More accurate reading by it “feeling” your finger instead of “seeing” your finger.
Nominal upgrade but an upgrade none the less.
A lot more benefit comes from how fast the software can detect you trying to unlock your phone, waking the phone, enabling the thumbprint reader (sonic vs light), then decoding the print and finally waking to your home screen.
I love the feature that lets me open the phone to home screen from the phone being asleep. Just put your thumb on a black screen in the right spot and boom, already at the home screen.
