With the exception of Apple and Motorola, literally every single OEM we've worked with ships (or has shipped) at least one device that runs this silly CPU optimization. It's possible that older Motorola devices might've done the same thing, but none of the newer devices we have on hand exhibited the behavior. It's a systemic problem that seems to have surfaced over the last two years, and one that extends far beyond Samsung.
Pathetic, but this has been going on in the wider industry for as long as I can remember - graphics chip makers come to mind, for instance. Still, this is clearly scumbag behaviour designed to mislead consumers.
On the other hand, if you buy a phone based on silly artificial benchmark scores, you deserve to be cheated.
