After nearly two weeks of struggling with video stream lag (jitter) I finally decided that the Galaxy Tab A just didn't have enough horsepower, even after running the OS thin. I'm going on almost a week now with the K1 and it's screaming. I still thinned the OS even though other users have reported they did not have to with theirs. For comparison, I loaded my wife's iPad Pro 9.7 and from what I can tell, the K1 performed better. Admittedly, I was taken by the size of the 9.7 screen but it also cost $850 versus $200. Now I'm just awaiting my Manfrotto D1 and I'll be on the move!
