Hello, First of all, all the contacts I mention here are stored as google contacts (not sim contacts) and they all have whatsapp and gtalk. With some contacts (not all) when I go to the phone contacts list and I click on it's avatar, a pop-up with contact options appears. The options are: call, sms, e-mail, but it doesn't show me whatsapp and gtalk! But I can see them from whatsapp/gmail. A contact was showing gtalk option but when I changed info about the contact (not the gmail) the option disappeared.... but, I rebooted the phone and then the gtalk option appeared. I still have contacts without the whatsap/gmail contact option. Is there anything I have to update/sync? Thanks.
