Since upgrading to iOS 10 I've noticed that often when I want to hang up a call, I now have to unlock the phone, navigate to the phone app to finally press the red "hang up" button.
Previously there would be some basic phone controls like "Mute" and "Hang up" even if the phone decided to lock while you were on the call. Now all I see is the contact information and call duration where the clock would be and "Press home to unlock" on the bottom. No phone controls.
How can I reenable the phone controls on the lock screen?

On the lock screen in iOS 10, a swipe right gets you to that new lock info screen (this used to get you call controls), a swipe left gets you the camera. I had the same reaction, how do I get to call controls?!?
It turns out, you just need to tap the phone number or contact name displayed on the lock screen, and you will get the call controls. This makes sense, in hindsight, as the swipe right now has a new behavior, but it wasn't obvious to me either.
Also, the sleep/wake physical button hands up the phone, so that's often easier than using the screen in many situations.
