		+	The service manual for the N900 indicates that the camera can be replaced. In principle this would allow upgrading the camera, however it is perhaps unlikely that a compatible camera of better quality will be easily available. There are also obvious warranty issues - the camera is not a user serviceable part.
		+
		+	The camera sensor is particularly sensitive to harsh light, and can be damaged easy if one is not careful where the camera is pointed.
		+
		+	Here is an example of a picture from a damaged sensor:
		+	[http://i.imgur.com/YDG8v.jpg]
		+	This one in particular has been sun damaged (dark spot) and UV laser damaged (purple marks). The dark spot was found not to be dust after a thorough disassembly and cleaning of the camera optics.
		+
		+	A suitable camera module replacement (if one cannot find one labeled specifically for the N900) is the camera module from either the N85, N96, or N79. They are all the same.
		+
		+	Here is a N85/96/79 module ordered from ebay:
		+	[http://i.imgur.com/jqSw2.jpg]
		+
		+	Once you have determined that your camera sensor is damaged, disassemble your N900 to this point (google ‘N900 service manual’ for instructions):
		+	[http://i.imgur.com/6ix0z.jpg]
		+	You can pop out the old camera with a razor blade stuck into the edges:
		+	[http://i.imgur.com/lCvit.jpg]
		+
		+	Notice there is a notch on the camera's edge that designates alignment.
		+	[http://i.imgur.com/InKwd.jpg]
		+
		+	Here is the difference between the N85/96/79 Module (left) and the N900 module (right). As you can see, there are some minute differences (serial/model numbers?), but the pinout is the same.
		+	[http://i.imgur.com/74vd2.jpg]
		+
		+	Replacing the camera is as simple as popping the old module out and putting the new module in.
		+
		+	Success! No more damaged sensor!
