iPhone and iPad models running iOS 10 or later will no longer require users to slide to unlock their devices. Instead users will need to press the Home buttom to access their Home screens. The change comes because Apple has added additional features to the lock screen, such as swiping left to access widgets, and swiping right to quickly open the Camera app. It is unknown at this time if the final version of iOS 10 will have an option to restore the slide to unlock feature, but it is doubtful.
How do I restore the slide to unlock option on my iPhone?
