Today while cleaning my lens, it became clear that there is a speck inside the camera on the lens. I have no idea how it got there. It's a nice small white speck. And it's driving me nuts. Is there anything I can do? Is it easy to open the camera to clean it? Will my warranty cover it?
Definitely do not open it- you will just make things worse and void your warranty if you're still within the warranty period. Take it to your local Panasonic service center. It's either a warranty repair or should be very cheap to get it taken care of.
