Framerate set in the FLA does not necessarily translate to a mobile device.
Solution
Always set a higher FPS rate in the FLA
Detailed explanation
Framerate It was noted that in tests on the clients device with a blank swf the framerate achieved varied with the framerate set in the fla. When the framerate was set at 16fps the maximum achieved on the device was around 8fps but when the framerate on the same fla was increased to 32fps the maximum achieved on the device also increased to around 15fps.
Therefore, it is advisable to set the framerate higher within the fla.
