Doesn't work with passcode protection – Callblock Review

The app doesn't show any caller ID warnings or data if you use passcode protection on your phone. This makes it rather useless. I've received half a dozen calls since getting the app and not a single one was flagged while all show as spam with a free reverse lookup search online. I'd caution against the app if you have a passcode.
