Key Use
Users can also use the End/Power key for navigation. For example, if users press the End/Power
key in an application, the Home screen appears. If users return to the application, the screen
that appeared before users left the application appears.

the current screen and displays the previous screen, dismisses a menu or dialog box, or

the previous tabs.
