Copy contacts from Samsung device to other brand
Using proprietary vendor-software such as Kies for backups usually jails you into that eco-system. If your Galaxy is still available, up, and running, rather use the following steps to transfer your contacts:


open the Contacts app
hit the menu button
select "Import/Export"
chose to export your contacts to SDCard (will store in .vcf format)


Now you've got a decent backup which should restore on any Android device (at the same place in Contacts), and even most other systems, as VCF is a standard format (VCard).

Alternatively, you can also sync all your contacts with your Google account from your old phone. They should automatically sync to all your other Android devices using the same account then.
