Here are two ways to sync contacts from Android to Android via Gmail. One is to sync the contacts from a Google backup, which we would show you in this part. And another way is to send the contacts as a vcf file to Gmail.

Transfer for Mobile can recognize and transfer overall file types, including contacts, apps, SMS, photos, videos, music and more from your phone and it also provides the phone backup & restore ability.
