1. Samsung is still in Apple's good books, as the iPhone 5S has a Samsung-made A7 processor
The mystery of the Apple-Samsung relationship remains largely unsolved. But Japan's Nikkei offered more evidence on Monday that chip-level relationships are hard to end.
The results of an earlier Nikkei Electronics' analysis were published in Monday's Nihon Keizai Shimbun, Japan's largest business daily. The analysis showed a Samsung-manufactured A7 processor inside the 5S.
This follows analysis done in September by Chipworks that also showed a Samsung-made A7. The A7 is Apple's newest processor that is used in the iPhone 5S, iPad Air, and iPad Mini Retina. It is the first 64-bit processor to be used in a consumer smartphone.appleiphonenews.co.uk

That working relationship is difficult to establish elsewhere from scratch.cnet.com
Apple, Cupertino, Calif.,has cut back on some purchases. It no longer buys iPhone screens from Samsung and has reduced iPad-screen purchases, suppliers say.
