Schedule Auto Shutdown on Android I have a Samsung Galaxy S3 and was wondering if it's possible (like on Blackberry) to setup a schedule for automatic device shutdown.

For example, on my previous phone, I could indicate for the phone to auto shutdown at 12AM and auto turn on at 7AM.

Is it possible on Android without download third-party app?
Natively, there is no way to schedule shutdowns and boot ups of the Android system. If you do decide to root there are applications in the Play store that can shedule a shutdown (you may even be able to make your own busybox script instead). However booting up will never be possible the way Android handles shut downs because when Android shuts down, it is not running.And so, there is nothing in memory to initiate any sort of startup process.
