Into the Driver's Seat

"Ever since Apple redesigned the iOS lock screen to remove swipe-to-unlock and require users to press the Home button instead, some iPhone users have discovered that accessing the Camera from the lock screen might be a challenge. The potentially difficult scenario is this; if you press the Home button to show the locked display which you would then swipe to access the iPhone Camera from, pressing the Home button also unlocks the iPhone and skips the lock screen with the camera access. I recently ran into someone who was convinced this set of actions meant their iPhone lock screen camera wasn’t working or no longer existed, so the behavior can lead to some degree of confusion as well.

Fortunately there’s a better way to access the iPhone camera from the lock screen in iOS 10 and newer, and it doesn’t involve using the Home button at all."
