CallsLock Blacklist

With this application you can block incoming calls and SMS on your phone. Having records of users who have already called you what date and time. Also return the call from the records themselves.

I know what you're thinking. Android already has a service to block incoming calls. Also your phone company has service blacklists. But with this app, total privacy is guaranteed, why the numbers have to tell others to provide this service? The application does not transfer any of your data over the Internet, or others.

It is a completely alternative implementation.

WARNING , some official mobiles with Android modified by the companies, has the locker codes, erased, so, It may not work well.
