Check out the new iOS 10 lock screen: lots of widgets, rich notifications and quick camera
Now, when you pick your iPhone up, you don't even have to press the unlock key to show the lock screen. With Raise to Wake, the iPhone will automagically unlock the second you pick it up and lift it to check the screen.
A popular demand has been putting widgets and notifications on the lock screen, and Apple listened. There are now rich notifications you can preview, using 3D Touch for more options. That 3D Touch action is more interactive, too, as you can shoot a message reply straight from the Peek preview window, too
Last but not least, the Lock screen on iOS 10 introduces a quick slide over gesture from the right that brings you directly into the Camera app, ready to shoot at will. Sliding the other way will bring you to the widget screen, where full screen widgets can rule the day, or you can expand the smaller ones by tapping on the More icon on the widget to start, say, viewing inline game videos if it's a sports app widgets you've pinned there. Neat.
