Why does my screen still turn off while charging? Possible Duplicate:
  Where is &ldquo;Stay Awake&rdquo; option in Ice Cream Sandwich on the Galaxy S3?  




I used to have an HTC Evo Shift. If I plugged it into a power cord, the screen would stay on until I explicitly pushed the power button. Now, I have a Samsung Galaxy S III. The screen turns off after a certain timeout regardless of whether it is plugged in. There is an option to change the timeout, but I would rather not be switching it all the time based on whether I have it plugged in. Is there an option I am missing?
Stock Samsung devices with TouchWiz (Samsung's version of Android) do not have this option to Stay Awake, and it is a good thing they don't. especially when they use the Super AMOLED screens. The image can burn in to the screen very quickly.
