1. “Back” navigation.
In iOS applications “back” option is placed in the upper-left corner of the navigation bar. It is used to navigate backward within the defined screens in the application however it is not used to navigate backward across the entire device.
In Android devices there are two types of “back” actions: “up and “back”. “Up” is placed in the upper-left corner of the top bar and is used to navigate up the application’s information hierarchy. In contrast, “back” option is presented as a button on the physical device that allows navigating backward across the entire device.

5. Actions.
In iOS applications can be accessed through the toolbar that contains action buttons, through the action button that is in the upper-right corner hand side of the navigation bar or through the buttons within the interface screen.
In Android applications it is recommended to display actions in the action bar at the top of the screen. If there is any need in displaying more actions than can fit on the action bar, either an action overflow icon appears on the action bar for devices that don’t have a hardware “menu” button, or the user accesses additional actions by pressing a hardware “menu” button on devices where there is one. Android applications may also use contextual action bar. A contextual action bar is a temporary action bar that overlay the app’s action bar for the duration of a particular sub-task.
