Is there a way to block unknown, private calls?

[OptimusTarzan]

Is there a way for the phone to natively block unknown or private calls. None of my HTC phones ever could. I know Samsung has the option. I've downloaded like 4 apps claiming to be able to but all failed. Does anyone know if there's a way that the phone can block these calls, or an app that actually works? Thanks.

I have an app called Hiya. Formerly known as Whitepages caller id. There are settings to block unknown numbers.

Mr Number does it

Call Blocker by NQ mobile is the best in my opinion.

I second this app. Works great. It sends calls to VM, which can be annoying when they build up and you need to delete them all. I think there's something in the newer OS that won't allow a pick-up/hang-up, which would be better in my opinion
