Can you tell me if there has been any issue that you know of with the charging unit? I bought my tablet Samsung galaxy tab pro 12.2 the the 2nd day after they came out from best buy. And first I have to say best buy has gone down hill compared to a couple years ago! I told them I wanted the note 12.2 I ended up with the galaxy tab 12.2. Not realizing it of course I go back next day with the tablet to buy a pen for it. First they tell me they don't have any individual ones for sale yet, then the other guy tells me that the note pen for 10.1 will work with it, now mind you they looked at my tablet I told them it didn't come with the pen, so I buy the $40 pen. I get home and it won't work! So next day I take it back to find out I have wrong tablet! But anyways my tablet has gone thru 2 charger now and as of today I have to buy a third! Why would it be doing this? I leave it to charge or put charger on and watch a movie can anyone help me please on this?
