Due to my health, I have had to quit most of my merchandising jobs and do more MS shopping. Several MS companies require that you have a android phone to install the gospotcheck app onto. I only have a old Tracfone that only does calls & text. I was researching and Tracfone have several different models that have the following different Android on.Android 5.1, Lollipop,Android 6.0, Marshmallow, Android 4.1,Android 4.4, KitKat. Does anyone know if I can use any of these for the Gospotcheck app? I really do not know a thing about cellphones.
