Where is “Stay Awake” 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?
