Sony's Xperia line seems to be the last one to still offer microsd support in a high-end phone. They also have headphone jacks, waterproofing, front facing speakers, and no camera notch. I kind of hate sony, but I might end up buying one of their phones next, just because they seem to be the only manufacturer that isn't removing features and calling it progress. On the down side, their commitment to updates is pretty lame.

Right now I'm on a Moto g100/Edgs S, which is a mid-range phone with a microSD slot and a headphone jack, but it has two camera holes in the screen, it's not waterproof and it has a single shitty down firing speaker. However, it was $270 used, so I figured I can live with this until I find something I actually like.

Oh, and both Motorola and Sony make it easy to unlock the bootloader, which is sadly not guaranteed anymore. I'm still a little salty at Google for permanently locking the bootloader in my old Pixel 2 and I sent it in for a repair.

> now nobody is offering a SD card slot

For some reason sd card slot is like audio jack, it's considered a thing for middle tier phones. Xiaomi have a bunch of them (various Redmis for instance), and Samsung at least used to, I haven't checked recently.

Sony seems to be the last manufacturer offering MicroSD slots in their high-end phones. (The last manufacturer that sells phones in the US, anyways.) They also include a headphone jack!

Samsung ditched both of those features in recent years.

I kind of hate sony, but in this instance they seem to be less shitty than everyone else.

If you're in Europe and don't mind a smaller player, the Fairphone has expandable storage out of principle, so your phone can last longer. Thus, you can expect all their future models to have that as well.

I think the best phones are made by Sony. If you want stereo speakers, SD slot, headphone jack and high end performance, it's hard to find other models than these manufactured by Sony.
