Operating systems that run on smartphones and tablets typically use a gesture-based lock-screen. Mobile phones manufactured by Neonode were unlocked by *** swiping to the right on its touchscreen. Apple's iOS; used by the iPhone and iPad lines, utilizes a similar unlock mechanism using an on-screen slider widget to the right. The lock screen also displays a clock, notifications, and provides audio playback controls. At first, Android did not use a gesture-based lock *** screen, electing to just require the user to press the phone's Menu button. On Android 2.0, a new gesture-based lock screen was introduced, displaying two icons: one for unlocking the phone, and one for setting the volume mode, activated by dragging the relevant icon to the center of the screen on a curve (similarly *** to a rotary dial). On Android 2.1, the rotary dial was replaced by two tabs on either end of the screen. Android 3.0 introduced a new design: a ball with a padlock icon is dragged to the outside of a circular area. On 4.0, the option to unlock straight to the camera is provided, while 4.1 adds the ability to *** unlock into a Google Search screen by dragging up.
Android 4.2 makes additional changes to the lock screen, allowing users to add widgets to pages accessible on the lock screen by swiping from the left edge *** of the screen. The camera is accessed in a similar manner by swiping from the right edge of the screen. Android also allows devices to be locked using a password, a pattern on a grid of 9 circles, or with facial recognition. Android distributions by other manufacturers typically use different lock screen *** designs than what stock Android utilizes; newer versions of HTC's Sense used a metallic ring dragged from the bottom of the screen to unlock the phone, and also allows users to launch apps by dragging their respective shortcut icon into the ring instead. On recent Samsung devices, the lock screen involves dragging in *** any direction from any location on the screen (with TouchWiz Nature devices, such as the Galaxy S III and S4, it is also accompanied by a visual effect such as a pond ripple or lens flare); similarly to HTC's lock screen, app shortcuts can be dragged up from the bottom of the screen to unlock directly into *** them.
