Hands-On With iOS 10's Overhauled Lock Screen
As can be seen in the hands-on video below, Slide to Unlock, formerly accessible through a right swipe, has been retired. Swiping right now brings up a widgets side panel, while swiping left opens up the Camera app. The widgets panel houses widgets formerly located in the "Today" view of the Notification Center.
The unlocking mechanism has been changed because with Touch ID, it was easy to bypass the Lock screen too quickly, making it difficult to see notifications.
New on the Lock screen is a "Raise to Wake" feature, exclusive to the iPhone 6s, 6s Plus, and SE, all three of which have an A9/M9 processor. There's also a redesigned Control Center and rich notifications, both of which support 3D Touch. In the Control Center, a 3D Touch on Flashlight, Timer, or Camera brings up different options, while 3D pressing on an incoming notification offers up options like replying to messages directly from the Lock screen.
