I played with the chords on some guitars in the store that I have been working on using my phone, and as I suspected, the 3-D fret is MUCH different than a 2-D fret on a glass phone surface. Go, figure. I will need much practice on real 3-D strings.
I plan to repair a separated bridge support piece inside my uncle's guitar(see damage below) and get it a new set of strings for it so we will have a practice unit as we continue to think about the hobby and what size instrument to procure.
