The material design of the request has removed this option from the dialog, and now needs to be in settings. When screen pinning is off it shows a description of how to use the feature, however when on it shows a switch to control whether it locks the device on exit. This setting defaults to on if there is a lock pin/pattern. Bug: 16957435 Change-Id: I59e0d64964cee4302e6ecff59e622cfe11422807
