Re: re: ALL FACTS ARE GOOD.
Only two international manufacturers profit from smartphones. Apple and Samsung. Apple make quite a lot more by way of profit. All the other international Android device manufacturers - about 5% of total market profits ! (though note: there are some new and very exciting Chinese manufacturers, who have taken a fork of Android and will probably market internationally soon).
You are trying to claim that Lenovo, HTC, etc don't make a profit from their smartphones? While their market shares may be smaller than Apple and Sansumg, they still sell a lot of units at fair prices yet you claim that "it's a fact" that they don't profit? Back this up with their financial reports.
Revenues from Android remains lower for app developers - there are some exceptions of course, but they are few and far between.
This is true, but it is steadily improving. While Android (Google Play Store) prices have been necessarily lower, in part due to competition as it's easier/cheaper to compete on the Google Play Store there is more acceptance of paying for content as the content is getting better.
Cost of development for Android, for those wishing to address the "full and larger market" is much higher than for iOS - for example the BBC has to spend approximately 3 times the amount developing for Android as for iOS.
This says more about the BBC, who excel at idiotic inefficiency, than Android vs iOS development. As another poster has already noted, it is much harder to develop iOS applications efficiently for multiple resolutions compared to Android where this requirement and the supporting toolkit has been in place from the start.
teenagers in the US express the desire to buy iPhones than Android phones, even though more are now purchasing Android phones because they can't afford iPhones.
You've partly answered this already in your sentence. People, especially impressionable teenagers, aspire to what is just out of reach - this is a normal fact of life. The better question is to look at the appropriate market group that has the most disposable income, the "20-something" crowd. This group are able to sign mobile contracts on their own behalf, are usually a little more financially astute than teenagers are.
Significantly more Android users plan to switch to using iOS than iOS users want to switch to using Android (even Android Authority ran a piece detailing this is the case).
Depending on the exactly how this is reported, this is not surprising. Firstly, there are considerably more Android users than iOS therefore more are likely to want to switch (numbers vs percentage). Secondly, there are a lot of awful Android phone models out there compared to Apple's relatively low number of devices and (generally) good design and build.
