Slide to unlock is gone in iOS 10, and isn't coming back. In its place is "press home to unlock" which works well for the iPhone 6s and newer, but isn't so smooth for older phones, requiring two button presses to open a phone. Here's how to only have to hit the home button once to unlock your older phone with Touch ID.
Phones with the M1 motion processor have "raise to wake" enabled by default in iOS 10, which senses when the user picks up the phone and wakes the phone. Older phones with Touch ID don't have that ability, requiring users to press either the power or home button, and then press the home button with a registered digit again to unlock the phone.
Here's how to turn "press home to unlock" off, and change Touch ID's iPhone unlock feature back to how it worked pre-iOS 10.
1: Open the "Settings" app.
2: Open "General."
3: Select "Accessibility."
4: Choose "Home Button."
5: Toggle "Rest Finger to Open" to on.
