Would be a bad move IMO.
Do you know how many times a day I have to unlock my phone? Can't imagine all the extra camera activations would be good for battery life. All this crap is just as useless as Siri. They should focus their efforts on improving features most people use.
Might they be able to figure out a way so that you wouldn't need have to use it every time you unlocked your phone?
But could have it as an option to do things like log in to your banking app.
Good idea about focusing on improving features that people use.
Maybe - and I appreciate this may be a long shot - they'll be able to do both?
