Here is the way to make your GEAR work with Bluetooth headset and you mobile device.
At the moment, it is now with Androdi 4.3. [I’m sorry that I forgot to try this way when my Galaxy S4 with Android 4.2.2.)
HOW TO make your GEAR work with Bluetooth headset + mobile device.
– Surely, you have paired up both GEAR and Bluetooth headset with your mobile device.
– UNPAIR Bluetooth headset
– DISCONNECT the GEAR (not UNPAIR)
– then PAIR UP Bluetooth headset again (now you will see select Bluetooth headset to work with CALL and AUDIO functions (if not, just mark it right away.)
– After having done the CALL and AUDIO functions ENABLED, then connect your GEAR.
NOW, it works well.
