Game Hangs or becomes slow in Android Version /devices

Getting Started Newbie Questions
#1

The Game is working fine in iOS devices and Samsung Note 5 . However it showing some lag or slowness in Android devices. 

Please help me out.  DO I Need to make changes in Config file ??

Here is code for Config file . 

local aspectRatio = display.pixelHeight / display.pixelWidth application = { content = { width = aspectRatio \> 1.5 and 768 or math.ceil( 1024 / aspectRatio ), height = aspectRatio \< 1.5 and 1024 or math.ceil( 768 \* aspectRatio ), scale = "letterBox", fps = 60, imageSuffix = { ["@2x"] = 2, ["@4x"] = 4.0, }, }, }

I don’t think your config has anything to do with it. (I don’t even know why it should)

It would be more interesting to know more about your FPS and memory usage, as well as things that take a lot of performane (many physic objects, particles etc.)

iOS devices are just faster than most Android devices, so maybe your app just needs better hardware.

Are you using Box2D objects?  I recently discovered that Android doesn’t handle Box2D very well once you get more that a couple objects.  I’m currently looking for a solution but, unfortunately, it looks like my current app will have to be iOS only. 

Android performance varies significantly as many devices have weak graphics cards or have taken other production shortcuts to keep the price low.  My new strategy is to test my apps on as many different Android devices as possible so I know exactly which devices can run my app.
