I must point out that your comment does not apply to a large number of markets. Consumers in India, for example, decide on a handset independent of which carrier's service they use.
Samsung's devices compare very favorably to similarly priced devices. iPhones are very expensive compared to Samsung's devices in India and in my observation (warning: anecdotal evidence), most iPhone owners that I know have sourced their devices from the US (usually via the used device markets) to get around the price problem. There's no wonder that Samsung continues to thrive and Apple continues to languish in the Indian market.
