I contacted Nokia UK by email but after no response, I rang them. The lady on the phone sent me an email with a free post label on it. I am to send this phone back and a replacement will be sent to me once received.

A few hours after phoning them, I received an email saying I was to take the phone to a repair centre and they can decide if the phone needs repairing. It's a good job I rang them, I prefer the response the lady gave me than the response from email.
