I just downloaded https://play.google.com/store/apps/d...V0Lm9zbWFuZCJd
to my Sammy GS3 Droid. Then I grabbed the maps for Thai, Cam, Laos and Myanmar.
I shut all data and cell functions off on the phone to simulate "lost in the back hills"
and it looks like I have truly off line mapping on the phone.
No need to have a cell or WiFi connection to have a functional GPS system
on my phone.
Now that the last of my midnight oil is burning dimly, I can sleep knowing my GPS issues are solved ... at least for now.
I'll get to play with this more on the 'morrow.
Then I can focus on a translator app. :)
