OziExplorer on Samsung Galaxy

Hi All,

A few weeks back there was a very helpful post regarding installation of Ozi on a Samsung Galaxy tab 2. I've now made the investment and have got everything largely working. For those thinking of going up this path, there are a few traps and I seem to have fallen for them all!

Trap 1 - The older Galaxy Tab is fitted with 2 cameras with quite useful resolution, while one of the cameras in the newer Tab2 is low resolution. A backward step.

Trap 2 - The Galaxy is a nice unit....but.... it comes in various flavours. (Quite apart from the 3 sizes, 7", 8.9" and 10.2". My experiences relate to the 10.2" one, fitted with 16GB native and a 32GB microSD card.) They will all (?) accommodate a maximum of 64 GB of memory/solid state drive, but come fitted with 16, 32 or 64 GB, and the 16 and 32 GB versions accept up to another 32 GB by using a microSD card. Some include provision for connecting to the 3G phone network, some have Wifi for internet connection, some have an inbuilt gps. I haven't yet worked out if these various combinations have different model numbers, but I don't think they have - certainly I haven't met any salesperson who can tell me how to positively determine which has what. Samsung's information on the web is very poor and no help. This is a serious issue that Samsung should address - there must be a lot of people who have paid $500-$700 to then find they can't access the web or can't use the phone network.

Trap 3 - There is still some doubt, but it seems that apps must be run from the internal memory, not the extra memory on the SD card. This is quite a limitation if you start off with the 16GB version.

Trap 4 - Thanks to some firmware quirk, writing to the extra memory on the SD card can only be achieved using a supplied file handling app. Consequently moving files there using a pc involves writing to the inbuilt memory then using the app to move the files to the extra memory. Any app that needs to write there won't work either. No gold medals for Samsung for that little trick!

Trap 5 - To add further confusion, the built-in memory is referred to by Samsung as "SDCard" and the user supplied memory is "extSDCard".

When we come to install OziExplorer things get complicated. It should be installed on the SD card (which one?). Since it needs to write configuration stuff it can't run properly on the extra SD memory. (Takes a few attempts and a lot of googling and searching specialist forums to arrived at that decision!)

Finally I've got it working, but no thanks to Murphy's Law. One last (I hope!) problem that I'd really like some help with - I've loaded the map files in ozfx2 or ozfx3 format, complete with their .map files and most appear to work fine. But the the one map we use most, the 250k Natmap coverage of the whole country doesn't come up properly. The map image is simply a blank screen, though the gps position and range rings appear correct, so I doubt that it is pointing to a featureless part of the map.

And the question - Has anyone managed to use this map? I'm wondering if the image is simply too big, or maybe I've produced a corrupted ozfx file, or ........

Any thoughts will be highly valued. (Alan - tried to MM you, but I don't think MM is working too well. If you'd care to work directly, please email johnandval at exemail.com.au)
