In what way are any of those phones “premium?” You’re literally listing the two phones I can get to access an SD card. The $1400 Sony or low to mid-range ones. So I have to compromise my choice in my diminishing feature set so that the common man can have yet another Galaxy, Pixel, or even an iPhone that doesn’t distinguish themselves beyond their OS/skin, camera count, and folding screens? Pick any one of these phones in the last 3 years and tell me what makes them unique and more practical than my Note 20 Ultra.
Plus, at least in the US, the common man is going for an iPhone. Apple just got nearly 60% of the market share here, so no, there isn’t a plethora of choices, and Android OEMs aren’t exactly fighting tooth and nail to provide exceptions in their products. So if I want a phone with actual “premium” features - such as cameras that eat up storage - and includes an SD card slot, it’s down to Sony and Sony alone.
