if you want to stick with a Samsung phone with SD card, you can look into buying a used/refurbished S10 series, or a FE phone with SD card.

I went from a Note 4 to used S10+ ( i managed to accidentally cracked the glass back) . if my next phone doesn’t have SD card, im eyeing a 512 gb phone.

I bought a used S10+ and owned a Note 4 when it was brand new, I don’t care about security updates. But I do care about app support and supported android version
