duplicate contacts

[gilcu3]

I get many duplicate contacts in the simple dialer app, while in the simple contacts app the contacts appear as one. I cannot find any pattern related to these contacts, do you have any idea?

I can also reproduce this. One thing that I observed was that the duplicates appear only for contacts that have multiple numbers saved. If there is only one number, there are no duplicates.

Hope this helps. As the same stated above, this does not happen in the contacts app. 😃
