Something tells me the companies sabotaged the smaller phones so they can charge more for the giant “pro” devices.
Bingo. As I said in another comment: People want features. Phone companies know this, so they artificially hold back the features that people really want for their bigger and more expensive phones, because they know if they make it bigger people will be ok paying more for it than if it was the same size but better spec’d. People see bigger and just assume it should be more expensive, so companies make phones bigger so people are ok with paying more for them.
