I’m having a hard time finding a photo organizing app that allows me to sort my files by filename. I guess most people don’t rename their files to something meaningful, but I’ve always done this. On the Gallery app that came with my phone, I can at least use Search to find files whose name contains my search term, although I can't sort them accordingly. With Google Photos—which is always the number one app cited when I do a Web search on best Android photo organizing apps—I can’t even search (at least, if there is a Search, it’s well hidden). Does anyone else rename their files to assist in finding particular photos, and if so, what photo app do you use?
