s7 photographs turning into grey box with exclamation mark

[Diverski]

@ my s7 takes pictures, I can view and share for 5 or 10 minutes, then those which have not been shared turn into a grey background with a white encircled exclamation box . In trying to upload then I get an unrecognized file format notification. Those which have been shared are not affected?????

Is the camera configured to save them to the SD card? If so, try changing it to save to internal memory.

That seems to have done the trick. It's easy when you know how. Is it because the SD card is too slow or is it more technical than that?

Thanks for your help it was getting very frustrating to have such a good camera available but not able to retain/retrieve the photographs I took.

It is possible that the SD card has failed. That would explain why the photos aren't getting saved there successfully.
