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.
