[quote:3e83ys0l]I think if the game has a problem why it runs smoothly in the web browser and also through the iPhone's application?
That baffles me and yes, if the game is faster in the browser on your device than an apk, the problem has to be Intels XDK.
You could try on your Moto G with Android 5.1 to make an App in the XDK without Crosswalk and see if this makes a change. So you can see if its a problem with Crosswalk.
Do you use Cordova plugins? Maybe one plugin cause a problem.
