I made update of some software applications on my Samsung Galaxy S6. Something has gone wrong because the phone was rebooting many times for over an hour. I reebooted it manually and than I realized my contacts disappeared. Now I try to synchronize contacts from my google account but it is not working from standard synchronization of the google account. I also exported all contacts to vcf file but Galaxy can't import it to My Contacts. What can I do to import / synchronize contacts with google account?
