I am exporting my project using Cordova and then using intel XDK to create an APK. I test my game regularly on my OnePlusOne and Nexus 4 and they both have around 50 - 60 FPS. I sent my game to a friend, however, who is using a Samsung Galaxy S3 and the game runs at 3 FPS! The real frustration is that, a few months ago, the game worked at around 40-50 FPS on the same Galaxy S3 and if anything I've made huge improvements to performance since then.
Have you any suggestions?
