How to properly rename the blank file on Galaxy J7?
I tried creating an almost blank Word file and moving it unto DCIM and renaming it to the same name as the thumbnails file, but it left a "." at the end if the name. When I tried to delete that, it gave me a message that the file name must contain at least 1 character. So it's not allowing the same exact name even after deleting the original thumblails file.
