and to answer your first question: the clean flash fixes it, with the same APK (i back up the APK and install using that to avoid the store changing things, and also try an uninstall and install from the store after that).

a clean flash of that march build = ok

clean flash of the april = no go.

will try a build halfway through, then half that, etc. to maybe narrow it down.

thanks for looking into this; totally odd.
