We can easily share an existing contact with friends, acquaintances or relatives, either as a file (VCF) or as a text file.

The contact can share on the Samsung device via any of the supporting apps such as WhatsApp, Facebook or other messaging apps.

The Samsung device offers another sharing function via a QR code, which scans the code and transfers all contact information to the other device.
