Not really surprising. It's all stuff that the vast majority doesn't care about. So you have the mainstream devices targeting the mainstream users, and the weird alt devices which tack on everything possible to capture the remainder of users who have this one weird requirement.
What I claimed is that the category "cheap android phones with all the ports and features" beats the category of "ultra-high-end devices without any reasonable ports" by far.
Flagship phones are halo devices, more jewelry than actual phones (this includes iPhones, the Pixel main line, the galaxy fold series, the S22 ultra, etc).
The vast majority of sales is in the mid range, including the Google Pixel A series (which still kept e.g., the 3.5mm port until last year) or most of Xiaomi or Huaweis phones.
But while with flagships, there's the one device to rule them all, in the midrange there's a different phone for everyone. Samsung alone has almost a hubdred different devices in this range at the same time.
And all of these have microSD, 3.5mm, FM Radio support, and many dual SIM support.
