I used that combination for a few days before sending my first S2 Sport back to Amazon, and it seemed to work fine. The reason for sending it back was that I think the sensor that controlled the wake-up gesture was bad. Hoping that the Classic (delivery tomorrow) is better in that regard.
The S2 and the S4 connected just fine, though, and seemed to work as advertised. I should add that in the brief time that I had it I didn't test every single function.
