Smartphones used to be a vibrant space with plenty of options to choose from and many unique features, but in the past few years, it seems that your options have dwindled to only a couple of brands. Come to think about it, customers in Western countries have Apple, Samsung, and Google. Maybe OnePlus and Motorola occasionally, but in limited quantities and only available at a few carriers, if at all.
Other mistakes related to spec-stuffing. Why on Earth did we have 4K screens on all recent Sony smartphones, when it is scientifically proven that at regular viewing distance a 2K screen looks perfectly sharp to most people? There is practically zero benefit to a 4K resolution on a tiny phone display yet Sony persisted with that for years.
Sony makes the sensors for the whole smartphone industry, it makes some of the best cameras in the world, and it certainly has the know-how to make the best smartphone camera of all time.Three separate camera apps, various pro modes with tweaks and toggles, professional camera LUTs, and a bunch of other features. Great to have, right? Well, yes, but not if you have to use a separate app to access each one! And Sony had three different camera apps. It was an utter mess.
