Share Your Location, Directly
Whether you're on your way to meet someone, or waiting for someone to meet you, let them know where you are--exactly.
Open up the S III's texting interface, then press menu and select add text. When the next menu pops up, select location > Google Maps. From there, you can opt to send your exact whereabouts to a friend via SMS.

Save That Screen
Take a screenshot. And another. And another. Taking screenshots with the S III is a snap--all you have to do is swipe the screen with your palm. So go ahead, take some more. And some more. And, well, you get the idea.
Other Android phones don't make it quite as easy. If you're using a phone running Android version 4.0 or later, you have to press and hold the Volume Down and Power buttons at the same time.
Give That Volume a Boost
If you're struggling to hear a caller, but you've already maxed out the phone's volume, you're out of luck, right? Not so fast: Samsung's phone offers a way to add a little bit more volume.
When you're on a call, an extra-volume button appears on your screen, next to the contact phone. You can use the button to turn up the volume when your call isn't coming through as loudly and clearly as you might like.
If you don't yet have a Galaxy S III, you will likely have to root your device to get this kind of volume boost. If you're daring, you can find instructions for doing so online.
Make the Phone a Flashlight
Stop digging around your bag in the dark, hunting for your keys.
If you have your S III in hand, you've already got a flashlight. The Assistive Light widget--which you can add to your home screen by going to Apps, selecting the Widgets tab, and choosing Assistive Light--turns the camera's flash into a flashlight when you need it most. Some other Android phones have this widget as well.
