Okay so somebody (could be a friend, one of my brothers...who knows I can't get anyone to fess up to it) has been using one of those fake caller id apps to prank call me repeatedly. Is there a way to block this....or is the phone actually thinking it is the fake number calling it? I don't want to have to change my number, but 45 minutes every night for the last 2 weeks is driving me completely nuts. Plus if it is one of my siblings, its only a matter of minutes before he gets the new number from someone else in my family.
