Call blocker is the most effective and easy to use inbox blocker. All you need to do is touch the screen to transfer the annoying number to spam and the system will block it. More calls from this number will never disturb you. True, if you still need to find out if the subscriber called again, then open the log, everything is recorded there in the statistics. You can add to the list any number formats, city, local mobile or international. Even hidden numbers will never be bored again, they will simply go to the blocker and will not affect the work with the phone.
