I having a big problem of transferring my all contact details to Android phone. I'm using Nokia Lumia 820 and wanted to transfer my all contacts to Samsung S4. Why this has become a tedious task? Windows phone supports to get contacts from other phones. But not for vice versa. I can't send one by one which is not easy since I have lot of contacts to transfer.
Are there any practical way to transfer all my contacts at once to Samsung Galaxy S4?
Waiting for a prompt reply.
