Samsung Galaxy S5: How to Enable and Use Bluetooth Tethering Feature in Android 4.4.2 Kitkat

Bluetooth tethering is a feature available in the Samsung Galaxy S5 that you can use to share your mobile data connection with other Bluetooth enabled devices that have been paired with your phone. Please note that since this feature uses mobile data to connect to the internet, you may incur additional charge when using this feature. To avoid a big bill, you'd better have unlimited data plan (if you often use this feature) or just use this feature as needed only.

How to enable Bluetooth tethering?
You can do so by using the following steps:

1. On any screen, swipe down the top of the screen using two fingers to open up the quick settings panel.
2. Tap Mobile data button to turn it on. The button turns green when it's enabled.
3. Long tap Mobile hotspot button to view more detailed settings.
4. Check the box in the right side of Bluetooth tethering to turn it on.
5. appears on the status bar when there's a Bluetooth device that is being connected with your phone and appears on the status bar as a sign that Bluetooth tethering is enabled.

1. Go to Settings.
2. Tap Connections tab.
3. Tap Bluetooth.
4. If Bluetooth is off, slide the ON/OFF switch to the right to turn it on.
5. Assuming that the Samsung Galaxy S5 has been paired with the Samsung Galaxy S4, tap in the right side of the Galaxy S5 and then tap Internet access. 
6. appears on the status bar when it's connected to the Samsung Galaxy S5 and appears on the status bar as a sign that Bluetooth tethering is now enabled.

As a note, you may notice that when using Bluetooth tethering the internet speed is slower than when using Wi-Fi tethering. But, since from the beginning Bluetooth was designed for mobile use, Bluetooth tethering consumes less battery than Wi-Fi tethering thus if you're tight with the battery life but have to act as a wireless hotspot for a long time, Bluetooth tethering will be the best choice for you.
