Many Moto, Samsung may be low cost and good value. I suggest you use the filters in Smartphone Selector.
- Legacy – add this filter first to reveal older phones without current build (but install instructions are still there). You may still find fairly current UnOfficial Builds for these phones or check out [LEGACY_BUILDS] collection for /e/ OS supported "legacy devices"
- Year Released – you can work forward from some of the oldest (~2012) once supported devices.
A cheap phone is the very best way to combat lack of experience.
