Just replaced my Samsung Galaxy S3 with this phone and I must say I do like it. One feature that I do miss, that Samsung had, was the ability to block the annoying telemarketer calls. I can't find the feature anywhere and from what I have been reading there is no consistent way that this feature is applied across the Android ecosystem. I would like to verify that there is nothing built in that I am missing. Lacking a built in feature, is there an app that worthwhile, paid or not, that will do the same thing. Thanks for any help.
