for the app if doesn't answer its because of the build you made in intelxdk it might not be compatible with ur device, try from intexdk not to export for cordova or other things, but the normal Android that says nothing else near it, and test it that way. also might be because you have to many audio files and your scene is preloading all. and instead of preloading when the app loading bar appears loads it when you should already play at freezes the game, happened to me a few times. its a bit tricky its a matter of building the right apk for that issue!
well for see if you have beta you go in the capx you made, unzip it since capx works like a zip and you'l get a project with a caproj file in it, open the caproj with notepad, and you will see version in the top lines, around 7-10 line. if its 205.2 then its beta, the stable release its 200 so the version should say Version : 200.000 or 200.001 smth if it says 205.200 then its the beta version the other way to check it is going into C2 and check the info button will tell you about the current version
