I have even got gdr3 and amber update on my Lumia 520 and yet the fm radio does nothing but a hissing sound.no fm stations are available at all on Lumia 520 in India
Update to my previous comment in this topic: I found fm radio stations on my lumia 520 after much hassle.Whereas even basic notsosmart phones can receive fm radio from my location,my Lumia 520 made me attach my earphone chord to a nail on the wall and then it allowed me to weak sound of some FM stations.it works but it works so poor
There is an fm radio on my Lumia 920, but it cannot actually tune into any stations here in Oslo using any app I have tried so far. I get noise with distant voices and garbled music. Very much like being in a cabin in the mountains or something. So I'm guessing the hardware isn't capable of actual radio reception. But the update did bring the radio feature, yes.
