Just be aware that these Android 4.0 and 4.4 systems are pretty low on the Totem Pole as far as Android Systems go and what ever you do manage to install and play around with, I certainly would not wish to have my MaxiSys App open in the background while using any non factory installed Apps. and certainly want to make sure they are closed out completely and not running in the background before running my MaxiSys App again or shutting down my tablet without making sure everything is closed out from the Android Home screen tray.
I wonder if the MS909, 919, and Ultra running Android 7.0 , would be more accommodating and stable for running other Apps on?
