Reply to S4 jog wheel/software interaction problem

I've been checking out my S4, and have run into a couple of issues. First and foremost is that there seems to be a problem in the interaction between my jogs and the software. When I manipulate the jogs, there is a serious lag time between when I actually do the motion and when it shows on the interface-alot of times the screen just freezes. I can hear it the motion/effect/scrub in my headphonees, although sometimes it sounds pretty distorted. Also, sometimes when a track is playing, the software periodically emits a weird buzz, interuppting the track.

Any input is greatly appreciated.
