I bought a Lumia 520 a few days ago and am pleased with it. But, the radio doesn't work at all well. I'm using the headphones that came with it, and realise they have to be plugged in to work as an antenae. But, I can hardly get any stations at all and everything just sounds like snow. I'm using it in the same places I used to use my old android phone, where I always had brilliant reception. I've read about an amber update improving performance, but this is a new phone, so surely shouldn't need the update? Any suggestions welcome.
