I am new to the android OS. I just discovered this the other day. If you press the home button while in your home screen or application screen it brings you to an "idle screen" where it shows two buttons at the top right corner. A close button and another button that can toggle phone or sound? You also have a clock and accu weather display. Along the bottom are shortcuts to some applications such as music, email, etc... Once the phone goes to standby by you see the clock in green text. My question is what is the purpose of this screen? and is there any way to disable it?
