I know this going to sound crazy. But anyway, my new note 3 is being replaced. It is a factory problem. But, while I'm waiting for my new note 3 to get here, I decided to download utorrent so I could download some files. As long as utorrent is running in the background, it will not restart. Once you close it, it will restart. I don't know why this is. But you are able to use the phone until your new one gets here. Good luck
