As one of the last persons in the world without a smartphone, I was looking at some options for minimal calling functions on a tablet without buying a data plan (just using a phone app that will let me make calls when I can get wifi). My daughter used to be able to do this with her Samsung Galaxy Player 4, and I thought that was a pretty cool device, but it is pretty old. Are there better options, such as a newer Galaxy Player? GP 4.2? Other tablets? I prefer a smaller screen such as the 4 or 5 inch samsung screens, but I'm open to other ideas. And what OS do I need - Jelly Bean 4.2?
