At first I went in and changed the setting for the iPhone 7 home button to unlock my phone by testing my finger on the Touch ID sensor. It more closely resembled how I used my iPhone 6s with the mechanical home button.
Now, after a few weeks of use, I have reverted that setting, requiring a “push” of the button to unlock the phone. This is because I use Notification Center much more now. I pick up my phone, it lights up thanks to “raise to wake”, and I swipe right to see my widgets. Weather, appointments, sports, etc are all there.
Resting my finger on the button bypassed the lock screen to quickly for me to access Notification Center. This way I can decide on the fly which direction I want to go.
It was perceived by me and many others as a strange decision by Apple at first to make this behavioral change to the home button, but now I understand why, and agree with the reasoning.
