This app does not control your voicemail service. If your blocked calls are being sent to voice mail, try another blocking method or use Google Voice. You can simulate a disconnected message by forwarding busy calls to a number that doesn't exist.

OUTGOING CALL permissions are needed for hidden mode, using the dialer to enter a password.

ACCOUNTS are needed for Google Contact Groups.

SEND SMS needed for auto replies and SMS routing.

INTERNET ACCESS is for licensing and the "Write to us" feedback tool.

LOG DATA is only sent with your permission via the "Write to us" menu item in Settings. You do not have to send anything if you don't want to.

    This has been a great app for me in the past. Worked like a charm on my old rooted Verizon Note 2 - never an issue. Just switched to the S5 on Verizon, which I rooted with towelroot. RCB now acts like it has root access, but it doesn't block anything. I asked a developer at Fahrbot about this, and the feedback was the root permissions were somehow damaged. That's nothing I did, nor is it somet

    Works great on custom roms, for those having issues do not backup app and settings then restore. Had a few calls slip through as the restore messed up. Clean reinstall. This app is the best hands down, thank you.
