I'm aware the play store can do a LOT more than the name implies. What I wasn't thinking about was this tool generally doesn't need the device to be on public IP, so remove the cellular access and have it behind a LAN firewall and it should be ok. Previously I was thinking along the lines of MMS attack's being a problem. I seem to get suspicious links regularly.
