When I go to "images", where I can see my different picture files, I can see the image preview in my downloads folder but when I click downloads the folder is empty.
I have tried restarting and turning phone off and on, toggling hidden files on and off, tried to move it by selecting the whole folder (it gives me an error) I tried downloading other pictures and I have complete access to view or move those. No matter what I try I can't get to the original image.
Try submitting an error report through the Samsung Members app!
Did this happen following a recent software update?
What software version is your S20 on? (Settings > About Phone > Software Information > Build Number [last 4 characters])
are the files showing up in any other folders, or are they completely gone from the phone?
