Unity 5 - Android platform performance issues...

Hello,

I seem to be having trouble getting my projects to run properly on Android devices...

More specifically, every project I attempt to run on my Galaxy S4 @ Android4.4.2 seems to be slightly choppy/laggy.

At first I thought I was being overly ambitious with graphic settings, scene contents, and lighting and shadows. After trying to run several extremely simple scenes, and experiencing the same choppiness as with the original project, I'm no long certain what to think...

My simple test scene has 1 plane, 1 cube, 1 camera, no shadows, mobile diffuse shaders only, no lights (aside from GI). The cube has a simple movement script:

 void Update ()
     {
         transform.Rotate(0, -90f * Time.deltaTime, 0);
         transform.position += (transform.forward * 10f * Time.deltaTime);
     }

The camera is static, no scripts attached, orthographic mode @ size 12.

The scene is simply a cube turning in circles on the plane...

In standalone mode, 100% fluid; in webgl 100% fluid, in webplayer 100% fluid; but when I switch to android, both the editor preview, and the version running on my android device exhibit slight choppiness.

Has anyone else been experiencing this issue?

Am I perhaps forgetting something absolutely critical when switching platforms to android?

Thanks.

NOTE: Unity V 5.0.0f4 // Android 4.4.2 // No changes made to default settings upon switching platforms to android.

/e I found this thread on the discussion forums: http://forum.unity3d.com/threads/very-poor-performance-on-android-after-upgrading-to-unity-5.306572/ It seems like it may be a Unity problem rather than a me problem :)
