Looking for advice for what to do. I purchased a used S5 about a week ago and absolutely loved it until today I got this message. There seems to be very little information about it and since the shutter works perfectly and has nothing visually wrong with it (I can take normal looking photos in the 2-3 seconds before the message appears) from the few other cases I’ve read it seems like this leads to an iOS issue. Is this definitely an iOS issue if not a shutter one? Are there any paths to repair other than sending it in to lumix? Thanks in advance
