The world's fastest-selling Android phone just got a little savvier. CNET How To is bringing its very best, unpublished advice to our newest e-book, "Mastering the Galaxy S4."

New to Android? We've got you. Google maven? You'll find plenty of hidden tips here, too. We've tapped through every last feature, button, sensor, shortcut, and blaster (seriously) to bring you the tips and tricks that help you master your S4.

CNET brought you a guidebook before, but for the S4, we've kicked it up a notch.

The e-book features hundreds of tips, from setting up your phone and kicking out the bloatware to customizing the interface, using Samsung's exclusive features, and even rooting the device.

Starting on June 24, you'll be able to purchase Mastering the Galaxy S4 from the Amazon Kindle Store to read on any of your devices.

To celebrate the occasion, we're treating you Galaxy S4 owners (or soon-to-be owners) with an exclusive giveaway. One lucky winner will win seven of the best S4 accessories, including the just-released wireless charging system, an S-View cover, and even the Smart Dock.

The winner and five runners-up will also be one of the first to own "Mastering the Galaxy S4."

To celebrate the launch of our e-book, one lucky winner will win these seven prizes!* Sharon Vaknin/CNET
