They quarrel and still work together, Samsung and Apple have a rather strange relationship. After series of lawsuits Samsung is believed to be again working on exclusively for making chips for Apple’s iOS devices as they had been since the first iPhone shipped in 2007.
Earlier this year Apple revealed their plans to switch to TSMC for next year’s iOS portfolio, but the buzz is Apple’s 2015 iOS devices will be using Samsung’s 14 nanometer FinFET technology, starting with the iPhone 7.
