• If you’re referring to the Xperia 1/5/10 series, there were earlier models by other manufacturers with a 21:9 aspect ratio. I believe LG were the first to do it with the Chocolate. Sony have certainly become the flag bearer for that aspect ratio in recent years, though. You’re correct that their sensors are used by many other manufacturers, however I think the biggest advancements in smartphone photography have really come from automated software processing which Sony is also not a leader in.

      Anyway, it was mostly a joke about the static nature of their recent devices (which I would argue has often been a good thing i.e. headphone jack and SD card slot). I’m sure there are plenty of areas where they have innovated in the past.
