I have both Deja Office and Google address book on my S5. Using the Bluetooth headset to dial hands free, the system is a little schizophrenic. It seems to use either arbitrarily and contacts in one yet not in the other are sometimes recognized and sometimes not.
Is there any way to default to either one of the contacts systems or the other? I would be happy with either. I cannot get rid of Deja office because I am on a Microsoft exchange server that shares the calendar.
