I've had my Nokia Lumia 520 for 10 months and all the buttons on the side have suddenly stopped working (around 1 week ago) so it's now impossible to unlock unless I plug it in to charge or get someone else to ring it. I've tried taking the cover off and manipulating the buttons but that has not worked. Even when I take the cover off the buttons don't work. Does anyone have any advice or should I just sack it and get a new phone? Thanks!
