My device is completely 'uncharged', and the battery icon blinks on and off with a blue bar when I am attempting to charge. I spoke with Samsung a few days ago and they told me to try one of the chargers at Sam's,Walmarrt or Best Buy to determine if it was the charger/cord or the device itself. I did, and determined it was the charger/cord. The Samsung rep at Best Buy took a new one from the box, and my device began to charge normally. Samsung is sending me a new one.
