Applications – On Verizon Samsung Galaxy 8 Version 9 (Android) Block outgoing calls and texts to a specific number


On Verizon Samsung Galaxy 8 block outgoing calls and texts to a specific number. I've tried several apps that say they block outgoing calls, but they didn't work. An app stated that in version 9 of Android, it did not have permission to block outgoing calls. I'm on version 9.

Is there an app or other type that I missed? Thank you so much!
