I switched from an HTC One M8 to this Samsung. To my surprise, it appears impossible to simply copy your Device Contacts to your Gmail Contacts, regardless of whether it is being done one at a time or in bulk. The HTC accomplished this very easily. HTC also had a button for eliminating duplicates. Naturally, I believed that the Samsung would be able to do the same thing but I appear to have been wrong.
Today I spent nearly an hour on the phone with ATT and then with Samsung, another hour. Worthless.
What I want is an exact duplicate of the contacts on my device to be on my gMail Contacts. I came here thinking the answer would be simple and that there would be a bunch of threads on it. I found a few, but none with a simple answer. Hopefully I am just missing it and one of you will be able to point me in the right direction.
