Suggested old Android phone to run emulators?

[StephenG1CMZ]

I am afraid that may be too recent to run the old HP Prime Android app (if you can find it). I have it running on Android 8.

Moravia have provided an update, and that ran on Android 12-14 (and maybe older, check the specs), except it was buggy and disappeared from Google Play after a few weeks.

Moravia are planning a beta release, but there is nothing in the Play store yet.
