    RCB is a powerful call, SMS and MMS blocker most for rooted phones.

    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 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.

    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:

    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

    Permissions, if you're paranoid go use some other app:

    RCB Pro customer here. Used to be really good. However, on the One Plus 3, it seems this app cannot handle anything newer than Marshmallow. I stayed on MM just so that I could keep using this app. Yesterday, I upgraded to Oreo, rooted the device, installed the pro version of the app Then installed root checker to check root for good measure. Root status showed success. Then attempted to test RCB Pro functionality To my utter dismay, it was broken again. I sent a report to the developer. As a paying customer I thought I would atleast get a response. Nothing. I am moving on from this app. The only thing that's worse than the app right now is the developer's arrogance. When I first installed this, the rating hovered around 4.5ish. It's down to 3.7 now Can definitely see why.
