Earlier quoted context omitted.
Samsung's line of Android devices became more profitable than Apple's iPhones at some point during, or just before this quarter (it's a bit vague because it's all based on estimates but it's basically happened already, we'll get the analyst estimates based on corporate announcements about a month after the end of the quarter). Some would consider that "making a killing".
This was based on the Strategy Analytics report? That was a little dubious, as it was based on saying that (a) half of Apple's profits are from the iPhone and (b) Samsung makes no profit on its desktop, laptop or tablet divisions at all. There was also some confusion over net vs gross.

They're all for the quarter that ended two months ago and say (Samsung-Apple) 53%-47%, 50-53% and 43%-57% respectively and they were all at more like 15-80% two years ago.
