My phone is small and real difficult to view thumbnails with but the one from bottom thumbnail with the top to bottom lighter column could be a shutter problem.
Please review cause if you have other frames with similar symptoms it is look at camera time.
The light column is actually just a light leak. I replaced the seals but didn't in a spot so every so often I will get an image like so. Thanks for the concern though, it's appreciated.
