The Camera on my galaxy s2(Android 4.4.2) looks like this when i run the color blob sample code. The same code works on my galaxy tab 2.

Tried with writing the code from scratch and other sample codes. There are no errors on both devices, but the image looks like this on the S2

Does anybody know how to fix this?

I recently had the same problem. I am using a Galaxy S2 as well, running Android 4.2.2 (from CyanogenMod). I had OpenCV 2.4.5 running okay. This problem showed up when I upgraded to OpenCV 2.4.7. After looking at the source code diff, I found the problem.

In JavaCameraView.java (line 149),

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH){
    params.setRecordingHint(true); //This line is breaking the preview

}

If you change this to params.setRecordingHint(false), or remove it altogether, the preview works again.
