Everyone, I have been looking for a way to block callers with the Moto X. I know my Brother-In-Law has a really easy way to do it right from the call screen, but I haven't figured out a way to do it with the Moto X. Anyone figure it out? I'd rather not have to install a 3rd party program, as I figure the software must have a way to do it, I just haven't been able to figure out where it's buried. Thanks!!!
