Couldn't find the answer by searching but I am sure some genius has already solved it and has the answer ready
Recently ported a game (which uses NGUI) to Android and although it works and looks good on a fair number of Android devices (inc Nexus 7) on the Galaxy S3 I got this:

Now the game itself is fine but all the UIs go mental if not right at the start certainly within a few seconds ... I have tried changing the camera clipping planes from 0.1-1000 to 1-10000 but that does not seem to make a difference. The UIPanels are set to Clipping: None
Any thoughts would be much appreciated
