Yeah, but AC are just repeating what Samsung say. I've met an example and it couldn't be adjusted away, which is what the OP reports too.
Remember that when S4 owners complained about storage Samsung told them to move apps to sd and issued public statements to that effect, despite the phone not actually having that feature (they added it subsequently when the mainstream media picked up on this, but only then). So I don't take statements like that at face value - they want to close this down, and have form in not checking whether their answers are correct first.
