"Unknown number" as in "not in your contacts" or when the number is hidden? I often get calls (expected ones) from people/companies I haven't saved. What I don't like is when the number is hidden though and those are the ones I'd like to block.
UGH.. this feature thinks anything outside of contacts is an 'unknown' number. This is NOT what I wanted. I need it to just block callers that come up on screen as "UNKNOWN" I've tried and tried to block these via making a contact and block it to no avail. :-\
