OS Upgrade and app marketplace

view story

http://forums.androidcentral.com – I upgraded a Samsung 6800 tablet and Samsung Duo phone from previous OS (gingerbread and 3.2) to Jellybean. However, I now want to install the new version of OneNote released 1 August 2013. This requires Jellybean 4.0+ to be installed, which I have done. However, the google market place system only reads my model number and says they are all incompatible. It also does the same for my NoteII and 10.1 tablet so am not sure what I need to do to install an app that I use on my desktop almost daily. A windows phone is not the answer. Any advise would be most welcome. (HowTos)
