Getting Started
The following set of topics will introduce you to your phone, help you get set up with service, provide an
overview of the phone screen, and get you started with basic phone operations.

Important Information 2
Important Information
The following topics provide important information that should be read prior to using your HTC One® A9.
Radio Frequency Exposure Operating
Instructions
This device was tested for compliance with the applicable FCC and Industry Canada specific absorption
rate (SAR) limits for radio frequency (RF) exposure during typical body-worn operations. To ensure that
RF exposure levels remain at or below the tested levels, use a belt-clip, holster, or similar accessory that
maintains a minimum separation distance of 1.0 cm between your body and the device, with either the
front or back of the device facing towards your body. Such accessories should not contain any metallic
components. Body-worn accessories that do not meet these specifications may not ensure compliance
with applicable SAR limits and their use should be avoided.
Important Note on Recoverable Data
Files and other data that have been deleted, cleared, removed, or erased from your device may still be
recoverable by third-party data recovery software. Even a factory reset may not permanently erase all
data from your phone, including personal information.

Introduction 3
Introduction
The following topics describe the basics of using this guide and your new phone.
About the User Guide
Thank you for purchasing your new HTC phone. The following topics explain how best to use this guide to
get the most out of your phone.
Before Using Your Phone
Read the Get Started guide and Important Information booklet that were packaged with your phone
thoroughly for proper usage.
Accessible services may be limited by subscription contract conditions.
Descriptions in the User Guide
Note that most descriptions in this guide are based on your phone’s setup at the time of purchase. Unless
otherwise noted, instructions begin from the phone’s home screen, which is displayed by tapping .
Some operation descriptions may be simplified.
Screenshots and Key Labels
Screenshots and other illustrations in this user guide may appear differently on your phone. Key labels in
the user guide are simplified for description purposes and differ from your phone’s display.
Other Notations
In the user guide, the phone may be referred to either as "phone," "device," or "handset." A microSD™or
microSDHC™card is referred to as an "SD Card" or a "memory card."
Access Instructions on Phone
These topics will help you find help on your new phone.

3. Tap a topic to view its contents.
What's New in Android Nougat
Android®7.0 Nougat brings new features that make working with apps and settings even more
convenient.
Multi-tasking Made Easy
Aside from flipping through running apps, there are faster ways to use the Recent apps button for
switching between apps.
●Want to watch a video while chatting at the same time? Use the split-screen view to display two
running apps side by side.
●Quickly switch to the previous app with a double tap.
For details, see Working with Two Apps at the Same Time.
Enhanced Notifications
See incoming information on a notification without having to open an app. If you received a new
message, you can send a reply directly from the notification. See Notification Panel.
Improved Settings
●Limit how much mobile data your phone uses. When you turn Data Saver on, apps in the
background won't be able to use the data connection unless you've set these apps to access
mobile data. See Manage Your Data Usage.
●Use the Quick Settings bar to toggle Wi-Fi and other quick settings on and off. See Using Quick
Settings.
●No more navigating back to the main settings screen by screen. There's a slideout menu that you
can open anytime to directly access the main settings.
●At the top of the Settings screen, see suggestions for how to get more out of your phone.
●Aside from changing the font size, you can also adjust the display size of items such as icons and
images. See Display Size.
