The way to tell if the phone is recalled is by the manufactured date. The recalled phones will have that date. Myself, I do not think Samsung will risk putting those phones on the market. The parts costs Samsung very little. Even if they fix it, and someone blows up a battery using the wrong charger, they will likely try to Samsung.
I think, again this is just my opinion, the amount of money Samsung has on each phone they are recalling, is way too little to take the risk of making them into refurbs.
