I don't know how it happened, but it appears that I have somehow changed the path that contains the ringtones. I was looking for them out of curiosity. Now, whenever I try to bring up ringtones, I get a directory listing of /storage/emulated/0. I can probably reset it properly, but I don't know they actually reside. I don't have root access, and I'm afraid that may be a problem in resetting the path. I'm thinking that's why a search with ES File Explorer can't find them, (or maybe I'm not searching for the correct extension).
I would be grateful for any suggestions.
