Still sort of new to the whole world of Android and with my Samsung Tablet 7 I am curious if there is a way to keep the screen on? Will it stay on if it is plugged into a power source? I have noticed in the settings that it will only stay on for a said amount of time (1hr). If not do I have to root it to get an option like this? Really I just want the screen to stay on when it is connected to a power source!!
