And here is where it gets goofy. The A6 is really just a S1, with no relation at all to the S2 S2+ or S3, now the S41 S42 and S43 are made by the same company that make the S1 and the A6. Crazy I know. S41 and the S1 have the same driver but that driver will fit in the S2 S2+ and S3 which most people call the A6 driver. It just gets crazier from there.
