I have been using my Nokia Lumia 520 for a while now, and I've been using for everyday things that the normal user would do, listening to music on the train etc, music would play normally on the phone, however 2 days ago I plugged my earphones into my phone for music, but when I move the phone, e.g to put it in my pocket or in my lap, I hear a loud thud and the music stops playing, I press play and the music starts playing out of the phones speakers (awkward) I have tried this with about 3 different headphones, and it happens with them all so it isn't the headphones, and seems there is something wrong with the socket, anyone know what to do about this? Its only been two months since I've had this..
