On my old phone (J3), I could select all my contacts and share to dropbox. They would be stored in my /personal/contacts/ folder as individual ,vcf files.
If I follow the same procedure on my new phone (A12), selecting all contacts, folder /personal/contacts/ includes just one file named contacts.vcf. This file includes only one contact.
If I do not select all, but just select a few individual contacts, the contacts.vcf file only includes details of the first selected contact.
Conclusion. However many contacts I select, only one is copied to dropbox in a file named contacts.vcf.
I am running Android 10 on a Samsung A12 phone.
