What kind of idiot designed Samsung and Kies Air? They're absolutely rubbish! I've used both of them and they often can't do a simple thing such as adding a mp3 file from my PC to the phone (Galaxy S4). I've been using Apple phones and Samsung Phones and I'm going to throw my Samsung phone to the rubbish for good and try out the new iPhone 6/ Air when it's released. Before that, can anyone tell me if there's anything that actually does the jobs between the S4 and PC? Thanks!
