The Galaxy S4 brings together superb hardware from Samsung with Google’s powerful, flexible Android operating system. Many people consider the Galaxy S4 to be the best smartphone on the planet. If you’re holding this book in your hand, you’re probably among them—or soon will be.

This book will help you get the most out of your Galaxy S4, and there’s a lot you can get out of it. Whether you’re just looking to get started, or want to dig deep into the phone’s capabilities, this book has got you covered.

About the Samsung Galaxy S4

WHAT MAKES THE GALAXY S4 so great starts with its hardware. Samsung gave it a 5-inch, high-resolution screen; a 13-megapixel camera for high-res photos and video; and a front-facing 2-megapixel camera for video calling and video chat. Its brain is a superfast 1.9 GHz dual-core processor. For keeping you connected, the Galaxy S4 has antennas for Bluetooth, WiFi, and GPS.


This book was written based on the T-Mobile version of the Samsung Galaxy S4. Versions from other carriers may have minor variations in what you see onscreen.

It has access to speedy 3G and 4G networks, which let you talk, text, and surf the Web almost anywhere in the U.S. (Anywhere important, anyway.)

Google contributed its Android operating system, with seamless access to YouTube, Google Talk, and other Google services. The worldwide developer community has created hundreds of thousands of apps in the Google Play Store (with more coming every day).

Put it all together, and you can do just about anything. You can get turn-by-turn directions, check weather and traffic, and identify landmarks. You can work with word processing and spreadsheet files and manage your email and calendar. You can take pictures and share them on Facebook, or shoot videos and upload them to YouTube. You can even turn the Galaxy S4 into a WiFi hotspot for getting up to five computers online.

Oh, and it’s also a darn good phone with great sound quality and all the calling features you could ask for.

You could figure out how to make the most of all these features on your own, but by that time there’d be a whole other generation of smartphones to learn. This book will put you on the fast track to all the Galaxy S4’s magic.

What’s New in the S4

Its predecessor the Samsung Galaxy S3 was a very popular and powerful smartphone. But the Samsung Galaxy S4 is nothing short of remarkable. It introduces countless new features, all of which are useful, and some of which seem more akin to magic than anything else. Here are some of the highlights:

  • Group play. Using this, a group of people can view and interact with music, pictures, games, and more simultaneously. That means playing games against one another, listening to music together, sharing pictures and more. Find out about it in Chapter 13.

  • Smart Scroll. Using this amazing new feature, you can scroll through web pages and other screens just by moving your eyes. Go to Chapter 1 to find out how.

  • Air Gestures. This feature was introduced in an earlier Galaxy model, but the S4 brings it to a whole new level. Move your hands to browse the Web, scroll through email, and do plenty more as well. (Again, see Chapter 1.)

  • S Beam. Beam me up, Scotty! This lets you share files by beaming them directly between your S4 and another device. Find out about it on S Beam.

  • Easy Mode. Don’t like a complex interface filled with small icons and too many features? Turn on Easy Mode, which makes using the S4 much easier, including big, easy-to-read icons. For more details about Easy Mode, see Chapter 1.

  • Dual Shot and Drama Shot. These are two new, nifty ways to use the S4’s cameras. In Dual Shot, you combine pictures or video from the front camera with pictures or video from the back camera in one frame. With Drama Shot, you take photos of a series of a subject moving, and then combine them into one photo, so you can perform the action. Head to Chapter 5, for details.

  • S Health. Want to get healthier? Use S Health. It’s an app that tracks your health, fitness, and diet by using sensors built into the S4 to turn it into a pedometer to track how many steps you take, and more. For details, go to Chapter 12.

  • S Travel. Find out everything you want to know about travel destinations, book travel, and so on. More details in Chapter 1.

  • New sensors. The S4 bristles with sensors that do things such as track the humidity, air pressure, and temperature. Check out Chapter 1 to see the amazing things they can do.

About This Book

THERE’S AN ENTIRE WORLD to explore in the Samsung Galaxy S4, and the little leaflet that comes in the box doesn’t begin to give you all the help, advice, and guidance you need. So this book is the manual that should have accompanied the Galaxy S4.

The brain running the Galaxy S4 is a piece of software from Google called Android. Samsung then tweaked Android to operate seamlessly with Samsung’s TouchWiz interface. Both Google and Samsung regularly issue updates that improve the way the Galaxy S4 works. So there’s a chance that since this book was written, there have been some changes to the Galaxy S4. To help keep yourself up-to-date about them, head to this book’s Errata/Changes page, at

IN THIS BOOK AND in the entire Missing Manual series, you’ll find instructions like this one: Tap Settings→Call Settings→“Voicemail settings.” That’s a shorthand way of giving longer instructions like this: “Tap the Settings button. From the screen that opens, tap Call Settings. And from the screen that opens after that, tap ‘Voicemail settings’.”

It’s also used to to simplify instructions you’ll need to follow on your PC or Mac, like File→Print.
