A screen lock is a software feature that keeps users from accidentally sending input to a device. For iPhone, there's "Slide to Lock" and for Android there are many variations. The point of a screen lock is for the device to be sure that the user is consciously interacting with the device as opposed to, for example, pocket-dialing. Similar to a key guard. They can also provide an extra layer of security by asking for a pin or a gesture.
