I recently got an SD card stuck in my GX7. It would release on the spring when I pressed down on it, but it was snagged on something and wouldn't come out the rest of the way. I noticed many posts about it but no real solutions so I wanted to post a solution in case anybody else is trying to figure out how to get their card out. I'm still not sure what exactly it was trapped on, but I cut a piece of packaging plastic (the very rigid clear sort) a bit narrower than the card and slid it in the slot label side, pressed down, and boing, the card came out. That's it.
