RCB is a powerful call and SMS blocker for rooted phones. It uses few resources and works silently in the background. Does not need to be set as the default texting app.

You can choose blocking methods including Offline Ignore and Kill. Can filter texts by content and block private restricted and non-numerical caller IDs.

Has a native Tasker plugin. Integrates with Google Contact Groups for editing lists through a browser.

I do not provide direct technical support for this app. You can send logs through the settings and I will examine them in due course but do not expect replies - I work on this app in whatever spare time I find.

I am always available for commercial support - if you're having problems with a purchase write to [email protected] for a prompt response.

Please do not try to get my attention with ugly ratings from now on I will ignore them and will only answer logs if I need technical feedback.

Notes

I will only use SuperSU on my devices so your best bet at getting this to work is to use the latest beta CF binary from here: https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133

If you have Xposed installed don't bother sending any logs I will ignore them.

If you experience problems follow the instructions below. If that doesn't help set SELinux to permissive mode and follow them again - it may.

To use this app together with auto-update in Google Play you must disable re-authentication in your superuser manager or you will keep losing root access and breaking daemon function. BELIEVE IT.

This app will not be able to block calls or SMS over IP. That means you must disable VoLTE VoIP or "enhanced messaging" if calls or texts are not being blocked.

Do not use third party backup applications - only internal backup. If you don't care for my advice and it doesn't work after restoring through your regular backup mechanism follow the instructions below.

Do not keep toggling the service options - YOU WILL BREAK RIL FUNCTION UNTIL REBOOT.

To remove the RIL daemon you need to uninstall the app and reboot your device.

Issues? Do this EXACTLY:

1. Back up using RCB internal backup
2. Uninstall
3. Reboot
4. Install directly from Google Play
5. Start app test function
6. Restore internal backup
