ZXContacts - Smart Contacts & Groups Manager App Reviews

I created the group and when I try to add a contact to that group the app freezes. I looked for tech support and youve got to be a member of Facebook; Im not and dont want to be. So I guess its the round file for this app. Too bad, it looked promising.

Can not figure out how to get the password that I put in to activate to lock out intruders. It just open to the contacts every time with out security code. ???
