Bluetooth Profiles
Each Bluetooth device can have one or more Bluetooth profiles. Each Bluetooth profile describes
certain features of the device. This tells your Galaxy Note 4 what it can do when connected to the
device. A Bluetooth headset normally only has one profile, such as Phone Audio (or Call Audio).
This tells your Galaxy Note 4 that it can only use the device for phone call audio. Some devices
might have this profile but also provide other features such as a Phone Book Access profile,
which would allow it to synchronize with your Galaxy Note 4's address book. The latter is
typical for a car's in-dash Bluetooth device. The example shown in step 4 of the "Change
Bluetooth Device Options" task is a Plantronics Bluetooth headset that has two Bluetooth
profiles: Call Audio and Media Audio. Media Audio allows your Galaxy Note 4 to play media
such as sounds your Note 4 makes and other media such as music, audio from a video, and so on.
You might decide that you only want to use the headset for phone calls (Call Audio) and would
prefer the media audio to continue to be directed to your Note 4's built-in speaker. In that case,
you would uncheck Media Audio.
Quick Disconnect
To quickly disconnect from a Bluetooth device, tap the device on the Bluetooth Settings screen
and then tap OK.
Wi-Fi
Wi-Fi (Wireless Fidelity) networks are wireless networks that run within free radio bands around the
world. Your local coffee shop probably has free Wi-Fi, and so do many other places, such as airports,
train stations, malls, and other public areas. Your Galaxy Note 4 can connect to any Wi-Fi network and
provide you faster Internet access speeds than the cellular network.
Connect to Wi-Fi
The following steps explain how to find and connect to Wi-Fi networks. After you have connected your
Galaxy Note 4 to a Wi-Fi network, you automatically are connected to it the next time you are in range
of that network.
1. Pull down the Notification bar.
2. Touch and hold the Wi-Fi icon.
