Thanks to Lee & Paul. Installed Chrome on Galaxy Note and radar now works fine.
No problem with space available although the controls, H+/- & V+/- are quite large. They are easily operated however but I wonder if they can be scaled down in relation to the radar display itself ?
Also, is it possible at the moment to alter the horizontal units from km to nm which would be more useful and avoid confusion with differing units ?
Thx
Chris
