I love the blocking mode on my S4 Active. I previously had three contacts in my "Allowed Contacts List". Last week I added a few more and, ever since, those on my "Allowed Contacts List" are blocked as well. I tried removing the new contacts that I had added in case there was a limit. However, it still blocks my allowed contacts. I also made sure I had "Allowed Contacts" set to "Custom". Any ideas?
