Sounds to me like your best option (for rolling back previous versions AND having “security” backups) would be to install an Android emulator on your PC and make dated copies of the game e.g. pre-release. In that way you’ll also have a backup (which is not using/wasting a device) and you can definitely roll-back to check/prove/restore your game state.
