There's not a tremendous amount you can do with NFC in the U.S., as our mobile payments infrastructure is more infra than structure. But you can have a lot of fun with the near-field networking technology and a couple of Galaxy S IIIs. Under Settings, Wireless and Network, pick More Settings. Then turn on NFC and S Beam. With this option turned on and two Galaxy S III phones, you can beam pictures, music, and contact cards between phones by holding their backs about an inch apart from each other. Try it.

Save data.This is a third-party app, but it's one I think most people should install if they're on limited data plans. Onavo Extend,
available in Google Play, runs in the background and compresses your
data up to 80 percent as it goes over the Internet. It can really make a
difference if you're surfing on a 1GB data plan. You pay a bit in
battery life and data speed, but I've found the tradeoff more than worth
it.
Save battery.
If you spend a lot of time with the screen on, you can change a few settings to make the screen and CPU use less power. Go to Settings, then Display, and turn on Auto Adjust Screen Tone. Back out, turn on Power Saving, and turn all the checkboxes on. This will reduce the power used by your screen and CPU. If slowing down the processor causes stutters or gumminess (especially in games), go back into Settings, Power Saving, and turn both CPU Power Saving and Screen Power Saving back off.
