Thanks to our new Call Screening tool, you are now able to ensure complete protection of your Android device. When enabled, this tool will enhance RoboKiller's call blocking, eliminating 99% of spam calls using our live audio-fingerprinting technology. Additionally, RoboKiller will also screen unknown calls ensuring you only receive the calls that YOU want. 

You can toggle Call Screening ON/OFF by changing your protection level in the RoboKiller settings section.
