Windows phone application features.

There are two mandatory basic features that a windows mobile application should have.

1. If user press "Back" button on the phone at the application's home page, it should log out.
2. If user press "Windows" button on the phone at any page in the application it should minimize.  

These features are common for the android applications too. But the second one is not exactly matching. Actually there is no windows key on android phones. ;)  Instead of that it has "Home" button.
