Hi Steve,

For me https://www.hpcalc.org/prime/docs/ and https://www.hpmuseum.org/forum/thread-818.html were a good starting with the Prime.

Backups generated by Shift+Mem->Backups in Prime Emu can be found in /data/data/com.hp.primecalculator/files/Backups/<name_of_backup>.zip in Android. The zip contains the contents from /data/data/com.hp.primecalculator/files/UserData/ with its subdirs. Unfortunately all the /data/data/ ... is only accessible on rooted Androids. :-{

I also only use the Prime Emu 2.1.14181 on Samsung Android 7.1. (unrooted) and a rooted Huawei Android 4.1.
Especially when starting Prime Emu I get in both environments approx. 10% of the starts aborted by Android's '"Application does not respond." message. Starting Prime a second time mostly succeeds and allows to restore a backup inside Prime Emu.
But in approx. 1% of Prime usage I do not get the Prime Emu running at all anymore. The only way out is using the PC Connectivity kit to restore my Prime Emu environment on the unrooted device (alternativly deleting the Prime Emu data by Android allows starting again but will vanish your work). On the rooted Android I can manually restore /data/data/com.hp.primecalculator/files/UserData/ to get happy again.
I seem to be not the only one with similar trouble, but in contrast to some other users running my favourite CAS calc on my phone is a much bigger plus than some instabilities with known workarounds.

When you face instability described before on your (unrooted) Android, you might need to find a way for Connectivity Kit on Linux, I fear.

Have Prime-fun!
