Why doesn't the Make space wizard in Nokia Suite remove duplicate contacts?

Make space removes contacts that have only the contact name filled in but no information in the other fields. Also, if you have two contacts with exactly the same information filled in in the same fields, one of the contacts is removed. Or, if you have two contacts with the same information, but one of the contacts has fewer fields filled in, the contact with fewer fields is removed.

To remove duplicate contacts on your phone, do the following:

  1. Just connect your phone to the computer.
  2. In Nokia Suite, go to View > Go to Support, or click Phone info and tools in the phone area.
  3. Click Make space under Capacity.
  4. Choose Contacts and Next.
  5. Duplicate and empty contacts are now deleted on your phone.
