My Samsung S4 and 997 won't speak to each other
 

Hi, I have recently purchased a 997 4S (DPK transmission) and while it's great fun to drive I have found that the bluetooth software appears not to be compatible with my Samsung S4. I don't care about the music aspect but I do need to be able to answer the phone hands free.
Has anyone managed to solve this issue or is there a software upgrade that I can apply?
Any help would be greatly appreciated.
Thanks
