Overall, the device is outstanding, especially after adding Nova Prime and customizing the user experience. There is however, one MAJOR, MAJOR problem. I have had to replace this device TWICE, TWICE I say due to a FAILURE of the USB 3.0 connection. The connection becomes loose, unresponsive and the device simply will not recognize the charger. I have no doubt that this problem will arise again, on this my THIRD GN 3. Needless to say I am HIGHLY disappointed with Samsung. The connection needs to be redesigned immediately. This is a KNOWN COMMON ISSUE. The folks at Best Buy told me that this issue is COMMON in the GN 3 and that they have accepted MANY GN 3 returns due to this issue. Come on Samsung, this is pathetic.
