Root Call Blocker Trial

Available in :


Root Call Blocker is the most powerful call and SMS firewall available for Android. If you have root, we guarantee that you will not find a more reliable app.

Unlike all other call filters, Root Call Blocker silently blocks calls at a system level. You need not even know its working and can choose to be notified only if specific people are blocked.


- A call will never go through
- Your phone never rings
- Reject calls from anyone, including restricted numbers
- Wildcards block groups of callers
- Keep blocked calls and messages hidden
- Five reject methods, including "Don't answer"
- Per contact logging options
- Encrypt your data


- Multiple profiles
- Groups integration
- Exceptions
- SMS auto-replies
- Scheduling
- Encrypted logging
- In-app replies
- Persistent and event notifications
- Customizable vibrations
- Export from hidden logs
- Encrypted backup
- Low profile
- And much, much more


If you need help, use "Write to us" in the app's settings, come visit our XDA Developers thread, our blog or find us on Facebook. You can tweet at us too!

Our ultimate goal is a Magicall for Android. Please, dont believe the hype about Extreme Call Blocker, or Mr Number, those apps are not the only ones that work on Gingerbread - RCB functions on any Android version 2.1 and up, is much faster and 100% silent.

This app DOES NOT provide Caller ID, it is not a dialer and it DOES NOT control your voicemail service.

If calls to numbers you have blocked appear in your messaging app or dialer, you should not be using this app as it is not a messenger or dialer. Its a call blocker.

If you find data disconnects, restart your phone. If it keeps happening, use a proper radio for your ROM or a more reliable ROM.

OUTGOING CALL permissions are needed for Hidden mode, refer to the Help for more information on why, possibly free hat racks for your tin hats.

INTERNET ACCESS mandatory to hook into the communications system. Log data is only sent with your permission via the "Write to us" menu item in Settings. If you block it using a permissions security app, RCB will NOT work.

INTERNET ACCESS is also used to track downloads and for very coarse (country level) location. If this worries you, you should probably be taking pills for the issue.

*** Like the way it works, but it doesn't start on reboot. And yes I have that box checked. EVO 4G

@Stratman that's supposed to happen. Just reboot and it'll work fine with coredroid.

by Stratman the 9/20/2011

This app constantly disables my rooted HTC Inc S's radio, despite restarting the telephony service. Incompatible with CoreDroid ROMs. Uninstalled.

by M the 9/19/2011

Crashes on HTC EVO 4G. I sent report. Hopefully will get fixed. If it does, I can change my rating.

by Anonymous the 9/7/2011

Great great Fixed all

Works as mentioned but caller can hear a partial. This app works as expected, blocks the number without ringing your phone. The caller will hear a partial ring before he gets the user busy message, I have tried all the reject methods (Fast reject, slow reject, alt reject, default) in all these modes the caller can hear a partial ring, Will give it 5 stars if caller gets a message "number unreachable" without partial ring, not sure if its possible as in fast reject (Reject command is sent without waiting for an Ack). Overall a good effort by the programmer.
