The system decoder in my phone's android version is buggy when playing vorbis, using a player with a different decoder solves the issue, but they are quite uncommon and I haven't been able to find a good one that is open source
I know people are going to say VLC, I used it for a while but the android app is quite buggy.
I currently use musicolet but it's closed source, I haven't been able to find anything else using search engines. If any anons know of a good open source music player that doesn't use the system decoder, it'd be quite helpful.
If I don't manage to find one I like I might just code my own or fork some nice player that uses the system's and modify it to use ffmpeg
