Android v7: Import close to 8000 complex contacts in one shot

Unfortunately most of the apps I tried expected one large VCF file and/or rejected VCF files with a lot of additional information, such as multiple "note" fields for one contact, too long "company" field, multiple phones with various attributes (primary/private mobile/business mobile/etc.) and so on.

After some searching and trying a few apps I found the following solution:

1. I have imported the VCF files to old Nokia Symbian based phone - Symbian has excellent VCF importer.




2. I used this app: https://play.google.com/store/apps/details?id=com.madajevi.android.phonebook.transfer to transfer the contacts directly via bluetooth.

App advantages:

• imports all contacts, even the most complex ones without skipping user defined attributes nor multiple repeated fields

App disadvantages:

• very slow (it took the whole night to transfer nearly 8000 contacts)




• asks for strange, unnecessary permissions (I kept refusing, forgot exactly which ones)




• synchronizes NOT with the local address book but with Google Contacts which means that your contacts actually are seen on the Internet - important security breach, do NOT use the app for confidential data




• full-screen user interface with no exit button - after finish you need to kill the app via task manager
