Book excerpt: The Nexus 5 is Google's first phone to natively run Android Kit Kat. As a result, the Nexus 5 is packed full of new features never before seen on any Android phone, such as a much improved Phone application, better voice searching, built-in caller ID that automatically searches the web for the phone number, and a completely redesigned text and video chat application. This guide will introduce you to these new features and show you how to use them. This book gives task-based instructions without using any technical jargon. Learning which buttons perform which functions is useless unless you know how it will help you in your everyday use of the Nexus 5. Therefore, this guide will teach you how to perform the most common tasks. Instead of presenting arbitrary instructions in lengthy paragraphs, this book gives unambiguous, simple step-by-step procedures. Additionally, detailed screenshots help you to confirm that you are on the right track. This Survival Guide also goes above and beyond to explain secret Tips and Tricks to help you accomplish your day-to-day tasks much faster. If you get stuck, just refer to the Troubleshooting section to figure out and solve the problem.
