It's the Kyocera DuraXV Extreme. I downloaded F-droid through the browser, and since I was coming from a GrapheneOS phone anyway, was already pretty used to a de-Googled setup. I haven't tried OSMand on it, but it probably can.

I did need to install Apps4Flip Mouse[0] to be able to use some apps that aren't D pad friendly, like Signal and Waze.

You might have some luck finding devices on other carriers with Jose Briones' Dumbphone Finder[1]
