A:AnswerSamsung makes certain tablets designed to work with S Pen. If the tablet originally came with a S Pen stylus it should work. Tablets that do not come with an S Pen are NOT compatible and the S Pen will not work on them. Kind of stupid design in my opinion, but is kind of the same issue Apple's Pen has with iPads. Only the iPad Pro supports the Apple Pen - iPad Air does not.
A:AnswerIT ONLY WORKS WITH THE TAB A THAT COMES WITH A STYLUS.... IF YOU GOT THE TAB A that DIDN"T have a stylus with it when you bought it, then THIS STYLUS DOES NOT WORK... IT IS ONLY A REPLACEMENT STYLUS if you lose the original one that came with the tablet...
