FORTUNE -- Things look grim for everybody but Apple (AAPL) and Samsung in the profitable segment of the smartphone market, according to a note to clients issued Tuesday by a team from Citi Research. The pie chart above and the paragraph below say it all:
Smartphone Market Faces Dramatic Structural Changes - At the high end (US$500+), Apple and Samsung continue to dominate. At the lower end, internet/software companies will lead in US$200-300 phones and Chinese brand and whitebox players will annex the sub-US$200 segment many with a zero hardware profit model. Given the rising competition, we expect many traditional mid priced US$200-500 smartphones to be wiped out in the next few years, leaving little future for companies that lack high-end exposure.
