I have tried multiple usb cables on my Samsung Tab A (all of which are Samsung cables) and with all of them a red x appears in the battery symbol...why is this happening? How do I make it go away? And does this have something to do with why I cannot import my photos and videos onto my pc? When I try it starts to import but then will say something went wrong please try again and it only imports a few photos before doing this but is not deleting them off my tablet. I am getting very frustrated with this as I have never had a problem with any of my Samsung devices before this!
