have a LG G3 that just got, paired it to a LG HBM-260 mono headset, pair up just fine but when I turn the headset off the G3 will not auto connect again to the headset . But each time I want to use the headset I have go into bluetooth settings and connect manually. I cannot find a bluetooth auto connect in the phone.
I have unpaired and paired a couple of times, and still have to connect the headset manually.
