Sam recently got a Samsung Galaxy Tab S7+ tablet, but he doesn't know how to turn it on. Leo says first thing is to make sure the tablet gets charged up. It'll take a few hours. Then on the edge of the tablet will be a power button. Press and hold the button for a few seconds until the logo appears. That will turn it on. There will also be a rocker button for volume control. It should also have a stylus. He can also read the user manual here.
