Because of the importance of transferring contact information from one communication vehicle to another, there are a number of different automated ways to transfer contact information. To import contacts, such as VCF files from computer to Samsung Galaxy S9/S8/S7/S6/S6 Edge, you need to ask help from an Android data transferring program named MobiKin Assistant for Android or Assistant for Android (Mac Version). With it, you can move contacts between your Samsung Android phone and computer in 1 click.

After that, you'll be required to connect your Android phone to computer with USB cable or WiFi. Just choose the method for connecting as you like.
Step 2. After connection, you need to do some operations to make the device be recognized by the program. For example, you need to open USB debugging under "Developer" option, and install a right USB driver on the PC. (Sometimes you may need to install the USB driver manually due to unknown reasons when the automatic operation is not working well.)
Step 3. When your Android is recognized by the Android Assistant software, you can see an interface like below. Now, directly click "Super Toolkit" in the top menu, and select "Backup" option.

According to a VzWireless Tech, take the battery out for 30 seconds and then put it back in. The phone should reset itself to pair the bluetooth headset with the phone. If that does't work remove the device from the phone and start from step 1. I removed the device from the phone then I took the battery out for 30 seconds. Then I paired the bluetooth and followed the next steps to complete the sync.
