Just tapping the name actually placed the call? What an idea. Just for fun, I looked at an older Docomo model on my desk by NEC. It is even worse:

Phonebook > Search > List of ways to search, NONE of which is just "show me my phonebook".

Let's try name lookup > Enter a string to search for > Search results > Choose a result > Dial.

Let's try Group > List of Groups > First Group > Choose name > Dial
