i found out later that pressing and holding volume up+down it close the app ... but its not that nice to keep holding 2 buttons to exit apps.
some of the apps leave my status bar visible but i dont understand why not all apps do that or why the status bar is not always on top on a device without buttons.
its just the way android is or apps that hide the status bar are not for android 2.3.1?
thank you and i hooe someone will give me a advice maibe i dont know to use it properly ... im new in android devices for shure.
maibe there is an app that creates a always on top home button? or some other way to manage. "exit." not closing it just going to desktop
