I just received my device, brand new from Amazon. When I went to activate it, it would not even boot up. When I plugged it in to charge, the battery showed 0%. How much charge was in your device when you received it? Should I be concerned that this was sitting in the warehouse for a long period of time at 0% state of charge? Generally, leaving a lithium-ion battery at 0% state of charge damages the battery and reduces it's overall capacity. Should I return it and get another one?
