Welcome to Android Central! Swipe down the notification panel -- do you see the flashlight in the Quick Settings toggles? If not, scroll all the way to the right of the Quick Settings bar, and tap Edit. See if there's a Flashlight option you can add.

On any Android device, you take a screenshot by pressing Power and Vol Down at the same time, for about half a second. It can take a little practice to make sure you're pressing them at the same time.
