Well I know there’s this app called Plexus or Plexor something and that supposedly helps you get an app past that requirement. I used it once to success long time ago by choosing a setting for the app and then it suddenly did not demand to get from the Play Store, so I know it works - in theory. But since that one success a few months ago, I haven’t gotten it to work again. I suspect maybe that phone at the time was completely de-googled or was a ROM such as CyanogenMod, and maybe the app can bypass if it doesn’t see the Google services at all.

Anyway, I will further investigate. I have some ROMed phones I can try on. If you want, I’ll post update in case you’re interested.

Thanks again for reply. Even if you didn’t have info for it I appreciate the courtesy.
