How to restart an Android device? Is there a way to restart an Android device? Now I have to shut it down and manually turn it on again, but I'm looking for a solution where the whole process happens automatically.

This might be device specific, mine is Samsung Galaxy S.
The menu you get when you press the power button should give you a list of options including Shutdown, Restart etc. If it doesn't, your phone's manufacturer might have left it out of the ROM.
