It seems that someone couldn't be arsed to include the company's actual facial recognition logo, and just popped Apple's in.
That's the weirdest thing about this; Samsung already has its own logo or facial recognition - as dull as it may be. Perhaps someone threw in Apple's as a placeholder for some unnecessary reason, although the slight tweaks to the image indicate this was deliberately copied and tweaked ever so slightly.
It's basically the IRL version of the 'you can copy my homework but change it a bit' meme. Although presumably, Apple didn't encourage Samsung to go ahead and life its icon in this instance.
As iMore points out, the images are identical, and no amount of subtle tweaking is going to fool anyone. The icon popped up during Samsung's portion on security and privacy, perhaps as some kind of meta commentary on the subject.
I doubt Apple is going to lose any sleep over it - not since it raked in £665 million in damages back in 2012 after a court ruled that Samsung had been infringing on Apple's smartphone patents. And as long as the icon isn't being officially used by Samsung for its facial recognition software, there's no harm done I suppose. Apart from looking bloody stupid. [The Verge]
