Surely, given the  growth of Xiaomi, Hauwai and &quot;Others&quot; in your own links the answer is obvious? Apple is, to a degree, insulated from competition, since you can&#x27;t buy a cheap equivalent from a competitor that runs the same OS and apps as your current phone.<p>I&#x27;d also question whether every device sold by Samsung and the other &quot;premium&quot; Android developers you mention, could be considered &quot;premium&quot;.<p>Certainly there&#x27;s a lot of Samsung devices that are aimed further downmarket than some of those from Xiaomi or Huawei (and vice versa). And even within a single manufacturer, you&#x27;ve not presented any evidence to suggest that people haven&#x27;t shifted from non-premium Samsung to premium Samsung. (You could argue that would inevitably lead to higher profits, but I&#x27;m not sure that high profit is synonymous with &quot;premium&quot;, so if that&#x27;s the assumption then it&#x27;s worth spelling out).
