I was very frustrated with this at first also. Still seems to work intermittingly but once I went to Samsung update settings I was able to update everything and this seems to have fixed my problem. There were many drivers that were either not yet installed or not updated. This took about 30 min for me to update everything. Seems to work now. Samsung has a great thing going with this eco system I hope they continue to polish their products and build upon this new galaxy eco. Hope this helps.
