Just got a Nexus 7 2013 and I'm not sure if this is normal or not.  The videos I take with the rear facing camera are somewhat choppy as I record motion.  This choppiness is present on the screen as I am taking the video as well as on playback.  When I am just viewing the camera screen and not recording video, the choppiness is not there as I move the device back and forth.  It's almost as if the processor can't quite keep up.  Anyone else have this issue?
