Lock screen

[5][6] iOS 10 made major changes to the lock screen, replacing the sliding gesture with pressing the Home button.

[7][8] As the iPhone X and iPad Pro do not have physical home buttons, the user must swipe upwards from the bottom of the screen instead.

[9][10] At first, Android did not use a gesture-based lock screen, electing to require the user to press the phone's Menu button.

[14] Android also allows devices to be locked using either a password, passcode, a pattern on a grid of 9 circles, fingerprint sensing, or facial recognition.

[11] Android distributions by other manufacturers typically use different lock screen designs than what stock Android utilizes; some 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.

[24][25] Amazon's Android-based Kindle Fire tablets display notifications of "special offers" on its lock screen, unless users purchase a more expensive SKU of the device which disables this feature.

The British court specifically ruled that Apple's lock screen[31] was an "obvious improvement" over that of the Neonode N1 due to its additional visual feedback through an on-screen slider graphic (unlike the N1, which only displayed a written instruction explaining the gesture).

However, Apple was warned that they would have been required to put up a bond as insurance if they were to allow the injunction to take effect, and any potential sales ban as a result would be limited to Germany.
