Wi-Fi Direct

Wi-Fi Direct allows devices to connect to each other directly 
via Wi-Fi, without a Wi-Fi network or hotspot, and without 
having to set up the connection. Your phone can use Wi-Fi 
Direct to share photos, contacts, and other content with other 
Wi-Fi Direct devices. 

For more information, see “Wi-Fi Direct” on page 92.

Bluetooth

Bluetooth is a short-range wireless communications 
technology for exchanging information over a distance of 
about 30 feet. You don’t need to line up the devices to send 
information with Bluetooth. If the devices are in range, you 
can exchange information between them, even if they are in 
different rooms.

Your device can use Bluetooth to share photos, contacts and 
other content with other Bluetooth devices. Many of the apps 
on your device provide options for sharing via Bluetooth 
under   Menu.

For more information about using Bluetooth on your phone, 
see “Bluetooth” on page 95.
