Bluetooth® is a wireless connectivity feature that has a short range and low power consumption. This makes it the perfect medium for sending information among devices in the same room. Using Bluetooth, you'll be able to connect to wireless headsets and entertainment devices like wireless speakers. You can connect to many car infotainment systems and share your device's contacts and music. You can share content, such as photos and contact cards, between two mobile devices.

Mark the checkbox next to Only visible to paired devices to make your device visible to nearby devices. A two-minute timeout is shown next to Visible to all nearby Bluetooth devices, and once it has reached 0:00, the device will revert back to visible only to paired devices.
From the Home screen, touch Menu > Settings
> Bluetooth.
To unpair a device you have connected to, touch the Settings
icon next to the device in the Paired devices list and then touch Unpair. You can touch Rename to change the name of the device. You can mark or unmark the profiles supported by the device to turn each profile on or off.
Many of the applications on your device allow you to share content you are viewing or you create with the application via Bluetooth. When using device features like the camera or browser, touch the Share icon or touch the Menu
key and look for the Share icon. When you touch the share feature, Bluetooth will be listed as an option. When you share content using Bluetooth, devices you have already connected to will be shown in a list, and you can connect to new devices during the share process.
When another device sends your mobile device content, you will see a Bluetooth authorization request message on the screen, letting you know the device's Bluetooth name and requesting you either Accept or Decline the request to connect. After you accept the request, the content will be downloaded from the sender and stored in Apps > My Files > sdcard0 > Bluetooth. You can also see the files transferred by opening the Notification Panel and touching the notification.
From the Bluetooth menu, touch the Menu
key to access the following options:
