By default Samsung Galaxy smartphones have a bluetooth visibility timeout enabled. This means that if you want someone to send you a file the transfer must be done within 5 minutes since you turn on the wireless module. The same thing with pairing your Galaxy with wireless headset, bluetooth speaker or any other gadget. Here is how to disable BT timeout completely and make your Android phone always visible to all nearby devices.
Disable Bluetooth visibility timeout on Samsung Galaxy devices with Android 5
- Go to Settings.

- Call the Menu.
- Tap on Visibiilty timeout:
- Tap on Never timeout:
Once you have done the steps above your Samsung Galaxy device will be always visible and discoverable by other devices via Bluetooth. All you have to do is turn it on.
