I have been using Extreme Call Blocker for a couple years. Since the ICS update it has started blocking my husband when I set the app to block unknown or private numbers. The dev tried to correct it, but said it's an issue with LG phones. He even offered me a refund which I declined because I will someday have a different phone anyway that works with ECB. Does anyone know a call block app that blocks unknown callers that works with LG phones? I really love my Spectrum but need the option to block certain callers as well as unknown callers.
