Shazam can't recognise any song with my Iphone. I also tried the other app midomi. Both apps don't work, even not after an update. I need to put my radio really hard to get some really poor results. Midomi shows a volume signal, but it only gets green when the volume of my radio is really hard. What is wrong?? I don't have any problems with my phone conversations, so my microphone is not broken... thanks!!
