The camera seems to take blurry pictures. Even with a cleaned lens, it seems like the focus isn't working.

It sounds like the springs in your lens cover may be out. If the lens stay open after you force them open, and don't bounce back into place, then it's most likely that your springs are broken or disconnected from the lens. You'll have to open up your camera to make sure! You may either have to replace the springs or simply reattach them to the lens cover. Please see the troubleshooting page for more information.
