What do you think is Samsung's phones' biggest drawback?

This portfolio slimming results from profit margins that slipped from the double to the single digits since the Galaxy S5 was introduced earlier in the spring. Samsung usually has a bestseller on its hand with each Galaxy S line flagship release, but not this year, as well-tailored competitors from Sony, HTC, LG, and even Huawei and Xiaomi, managed to make the S5 just one of the many. Now Samsung is compensating with the decked-out Note 4, but in the meantime it issued a memo to suppliers for cutting costs by 30%, intending to “increase the number of components shared across mid- to low-end models, so that we can further leverage economies of scale,” as per one executive.

Is it the design, the software, the price, or simply the confusing variety of similar handsets it spits out every year.
