The Galaxy S10e is my current phone, and I'm not sure what I will do when it stops receiving security updates. It's basically perfect. It still has an SD card slot. It still has a headphone jack. It has wireless charging. It's reasonably sized. And it had flagship-for-the-time specs (albeit slightly less than the mainline S10 or S10+). Samsung doesn't make anything comparable to this anymore.
The only drawback is that the battery life has gotten worse since I originally bought it. But if I could easily swap that out, I would keep it for another five years.
EDIT: Oh, and the fingerprint scanner on the power button seems to work way more reliably, IMO, than the embedded fingerprint scanners under the touchscreens.
