Rootable modable phones, with a 3.5mm headphone jack, SD card slot, and an ultrasonic fingerprint reader cherry on top. Maybe some heart rate monitor sprinkles if you are so inclined. My S10 that I still use checks all of the boxes minus root. It feels like I have a sundae with all the high quality toppings I could want... but no proper ice cream. And I want the whole custom sundae, which these days seems impossible to find.
It’s important to remember that even if a company did that and the customers who said they wanted it all went and bought one it would still likely be a tremendous waste of the manufacturer’s money. And then there are all the people that say it’s important to them while they only use it to point at while shouting at iPhone users despite not using their phones any differently.
These still exist, for now at least. Just not any flagship phones. My Oneplus nord n30 has all of this (well idk if the fingerprint sensor is ultrasonic, it's on the side and fast though). And I'm pretty sure a lot of Motorola phones have these as well. Only downside is not the best processors or cameras, but are good enough for me at least.
