Wife and I are new Galaxy On5 users. Currently, our contacts are in my Google gmail account with both phones linked to that same gmail account. Because of experimenting (new smartphone user), when I display our contacts list: ... On my phone I see: ...."Contacts on Google", I see the list of contacts. ... "Contacts on Device" I see only a single entry which is my name. ... On my wife's phone I see: ... "Contacts on Google" - I see the list of contacts. ... "Contacts on Device" - I see a list of contacts like on Google but some are missing. I want to keep our master list of contacts on Google gmail. My questions are: ... 1. Will having a list of contacts "in the device" cause problems? ... 2. Should I delete all of the contacts in my wife's "Contacts on Device"?
