Severe performance issue with Camera on Android running on Galaxy S2

Hello guys,

I am building an app for both iOS and Android and i have a big issue that i don't know how to overcome on Android.

I have the following code:

------------

var vid:Video;

var cam:Camera;

cam = Camera.getCamera();

cam.setMode(320,240,12);

trace("CAMERA:",cam.width, cam.height, Camera.names);

vid = new Video(320,240);

vid.attachCamera(cam);

vid.x = 0;

vid.y = 0;

addChild(vid);

-------------

If i set the camera mode to 640x480 the app freezes/refreshes every 20/30 seconds.

(works on iOS without any issues.)

I have tried using air versions from 3.6->3.8 with Direct, CPU and GPU mode.

Android version on my test phone phone is 4.0.4.

Thanks!

After HOURS of testing managed to see that the problem only occurs in PORTRAIT MODE! lanscape mode works as it should

Any thoughts ?
