I've read about this several places, wondering if others are having or have had this issue. Powered up my 1 week old GX7 today, had a heavy vibration, which was new and then the message "Please turn your camera off then back on". I did. Several times. No joy. Greeted with the same message each time. Tried charging the battery full up (it was at 70% or so). No joy. Tried taking lens off. Taking out card and swapping it. Basically, nothing worked. OneCall was decent enough to expedite my return, getting me a shipping label and creating a new order in just minutes - but I have to wait for my camera to get there before they will ship the replacement. I have a big event next weekend. I am worried. So anyone else have this issue? I see the 1.1 firmware specifically addresses power on stability, but I couldn't update. Anyone have the issue WITH the new firmware?
