I posted some more results on the Ludei forum. Here it is for those interested. The only 3rd party plugin that I use is "Function"
On the iOS devices the game will crash, at random times. There is no error reported on the console, and I am not sure if there is a way to catch error logs. Also the sound doesn't work 100%. Also on one of the iPhones, not all of the images render.
On my android device there are no crashes, the sounds works less - but I think you know about this issue.
Is there any way I can help in resolving these issues? If needed I can export a partial version of the project, but only if it will help.
So by using the same construct export file, and the same launcher these are the issues:
Samsung Galaxy S3 (ICS): Sound issues, no crashing.
iPad 2: Better sound, random crashing.
iPhone 4s: Better sound, random crashing.
iPhone 4: Better sound, almost no images (sprites) load. Haven't experienced crashing yet.
Sony Experia X10: Will test later and update.
