14. Android OS x Some Unique
Features
• Near Field Communication (NFC)
Most Android devices support NFC, which allows electronic devices
to easily interact across short distances. The main aim here is to
create a payment option that is simpler than carrying credit cards
or cash, and while the market hasn’t exploded as many experts had
predicted, there may be an alternative in the works, in the form
of Bluetooth Low Energy.
• Alternate Keyboard
Android supports multiple keyboards and makes them easy to
install; the SwiftKey, Skype, and 8pen apps all offer ways to
quickly change up your keyboard style.
• Infrared Transmission
The Android operating system supports a built-in infrared
transmitter, allowing you to use your phone or tablet as a
remote control.

15. Android OS x Some Unique
Features
• No-Touch Control
Using Android apps such as Wave Control, users can control their
phones touch-free, using only gestures
• Automation
The Tasker app lets you not only control app permissions but also
automate them. Do you only want your location services to be
active during the day? Want to create a customized way to start
your music—for example, with a voice command and at a certain
volume?
• Wireless App Downloads
Accessing app stores on any mobile device can be frustrating, but
iOS makes it a little more difficult—download an app on your
computer, and it won’t sync to your mobile device until you plug in
and access iTunes. Using the Android Market or third-party options
like AppBrain, meanwhile, let you download apps on your PC and
then automatically sync them your Droid, no plugging required.

16. Android OS x Some Unique
Features
• Storage and Battery Swap
Android phones also have unique hardware capabilities.
Google’s OS makes it possible to remove and upgrade your
battery or to replace one that no longer holds a charge. In
addition, Android phones come with SD card slots for
expandable storage.
• Custom Home Screens
Android comes with this capability from the get-go. Download
a third-party launcher like Nova, Apex or Slide and you can add
gestures, new shortcuts, or even performance enhancements
for older-model devices.

17. Android OS x Some Unique
Features
• Widgets
• Apps are versatile, but sometimes you want information
at a glance instead of having to open an app and wait for
it to load. Android widgets let you display just about any
feature you choose, right on the home screen—including
weather apps, music widgets, or productivity tools that
helpfully remind you of upcoming meetings or
approaching deadlines.
• Custom ROMs
This is a big one. Because the Android operating system
is open source, developers can tweak the current OS and
build their own versions, which users can download and
install in place of the stock OS. Some are filled with
features, while others change the look and feel of a
device. Chances are if there’s a feature you want,
someone has already built a custom ROM for it.
