Thanks for your response.
The chap who mentioned the Samsung Tab A advises that it is the model T590 which you mention and it is the one available here in Australia.
Can I assume that the OS (Android 9.0) installed would also be the 64 bit version? Surely it would as defeat the purpose of having a 64 bit processor.
I have also since found that the Samsung Galaxy Tab A 10.1 inch model T510 has an Exynos 7904 processor which also is supposed to be 64 bit. IT also has a better screen resolution (1920 X 1200) which may not look much better than 1280X800 on an 8 inch screen. It also has 3GB RAM (the T290 only 2GB) but I'm not sure if that would cause any issues as I will not be running any other apps at the same time as GO FLY.
Just noticed you are in Kamloops which we briefly visited on the Rocky Mountaineer.
