There should be a significant difference in camera quality between the S3 and the tab 2 10.1. If I'm not mistaken, the camera on the tab 2 is 3.2 mp and lacks autofocus. Comparing it to the S3 which has one of the best camera's on a smartphone isn't a fair.
The tab 2 would cry.
I don't think Samsung focused on the camera when building their tab 2 series.
