I do not know of a currently supported 32-bit armhf OS for the PinePhone.
This issue affects Desktop JavaFX linux touch as well, so I suppose I'll need to dig into adding that in, which was
mentioned on this older issue: https://github.com/javafxports/openjdk-jfx/issues/329#issuecomment-459433106

Thanks for the quick reply!
