Nokia N86 - photos fault

My Nokia N86 is ok - I've had it a few months - since it was released in the Summer I think. However, it has developed an annoying fault in that the photos screen keeps coming up when you put the phone down - I assume that it thinks the shutter is open so the sensor is playing up. I wouldn't mind but despite it being 8MP the photos aren't much good unless it is a bright days outside. Indoor and slightly gloomy photos are hopeless - always blurred.

I bought the Nokia as I normally buy NOkia and didn't want to follow the crown with an Iphone - now I understand there is a reason why people are buying the Iphone - it is better...

I do use most of the functions on it though - Sat Nav, Email, Photos, as a phone!, MP3 player as it plugs into the car...
