Bloqueador de Chamadas Total

"BreakCall" blocks all calls from numbers not saved in your contacts before they even appear on your phone screen. All blocked calls are recorded in the app's history, allowing you to decide if you want to return any of them. In addition, the app has its own dialer and access to your contact list, allowing you to make calls normally, conveniently and securely.

When a number calls and it's not in your phonebook, nothing appears on your phone's display, leaving you free to use your phone as you wish.
