I know this has been asked before - I've read the threads. However nothing seems to work. I've put an MP3 (the consensus seems to be that's best) file in every folder I can think of, reset my phone and it still won't show up. The file shows up in file explorer when I plug in to PC, and I can view it through the "files" app on my phone. But in the ringtone settings it's not there. Anyone have anything else I can try? It seems like such a simple thing that this phone can't do, it's baffling. TIA for any help or suggestions.
