I know of no recall for any Samsung Tablets. If your tablet is under any warranty, you can contact them and see about a repair or replacement. However, if the tablet is out of warranty, and you have had it for a while, then most likely it was dropped, knocked, etc. and something has come loose inside.
If it isn't under warranty you have the option of opening it up (yes, I know it isn't simple, but there are instructional videos all over the net) and checking the connections yourself or you can take it to a local tech or repair place.
