Samsung comes to mind, surely it's big enough to produce high-performance phones that can compete architecturally with Apple's SoC as well as addressing the developing nation / low-cost phone market?
The tighter focus, combined with the fact that Apple rakes in more cash to spend on R&D, is why their engineering team is able to win out here.
Sure, yes, but not at a volume that allows them to create a processor that competes with iPhone only on their flagship model. Also, they can't charge $999 for their flagship. The average sales price for an iPhone is higher than the flagship model at Samsung.

From everything I can tell and looking at the numbers, the high end Android market is minuscule.
Android manufacturers have more competition, and have to address the low end of the market too. Their money, and attention, is spread in a wider swath.
