Harold, if you private message me the area you live in, I can provide some names of the local SCDOT maintenance personnel that you can contact and see what can be done. 26 years in engineering at SCDOT.
I use a Droid 4 with C:geo 99% of time. My Galaxy tablet runs it as well, so i don't see why yours wouldn't. I always have my Garmin Dakota 20 along for backup tho if you get in an area with poor cell phone coverage.
