I paired my Desire S to a Motorola HX550 and for the past few months, both phone audio and media audio (viber, skype, etc) have been working very well. Normally as soon as I switch on the headset, it picks up the phone and connects. But for the past 2 weeks, my HTC does not connect to the headset automatically as before when headset is on, I have to manually connect through Bluetooth advanced settings, but not only that, it will now only connect to media audio but not phone audio. So voice calls are not connecting to headset, but viber, skype etc are fine.. Can anyone help please ??..
