While using RoboKiller, you may notice that the RoboKiller shield, located on the top right, changes colors. The colors reflect your selected Protection Level. There are currently 4 different levels of protection.
Red = Basic protection: RoboKiller will block Neighbor Spoofed calls that match your phone number's first five digits. (In addition to the known spam numbers on our Global Blacklist).
Yellow = Standard protection: RoboKiller will block Private/Unknown callers and Neighbor Spoofed Calls. (In addition to the known spam numbers on our Global Blacklist).
Green = Enhanced protection, RoboKiller will only allow numbers listed in your contacts to ring.
Blue = Complete protection, RoboKiller will block 100% of unwanted calls while screening unknown callers so you know who's calling before you answer.
The level of protection can be changed at any time within the Call Blocking section located within the Settings tab in the RoboKiller app.
