Has anyone encountered an issue trying to use a paired Bluetooth device to make hands free out going calls via the S7 phone (when phone is in sleep mode and locked). If anyone had a workable solution for this issue, I would appreciate hearing about that solution. As mentioned, the bluetooth device is paired--and the device is the Jabra Freeway. There is communications between the S7 and the handsfree device when the phone is unlocked and awake. Would also like to make S-Voice my default phone dialer if that can be done. Lastly the device doesn't seem to stay bluetooth connected for some reason.
