My tablet just all of a sudden won't work on my computer. I plug it in and my computer says that it malfunctioned and could not be recognized. Windows code 43. Anyways I sent it.to Samsung for repair and they said they fixed it. It's not fixed. It still does it. I reinstalled the drivers a million times. I tried kids. However I could.never get the tablet to connect to kids wirelessly. I did a factory reset. I didnt try another computer but all my ports work with other.devices. is it my cord? I have a case with a magnet clip and when I charge the tablet it lays on the cord.
