Root Call Blocker

Un appel riche en fonctionnalités et bloqueur SMS

RCB is a powerful call, SMS and MMS blocker.

As of Android 8, root blocking is not possible and RCB will default to no root mode, which does not block SMS at all. There are specialized apps that will do that better than RCB set as the default messaging app.

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, I will ignore them and will only answer logs if I need technical feedback.

Root users must make sure they have the latest binary, either Magisk or SuperSU.

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

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

To use this app in root mode 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.

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.

In root mode, to remove the RIL daemon you need to uninstall the app and reboot your device.
