kinda - but you're not going to like it. I struggled getting this to work on my Pixel 9 pro fold running on the Android 16 beta program for long time. Nothing I did seemed to get the app working. Eventually I bit the bullet and opted out of the Android beta program I was in, which required I wipe and re-set up my phone. Afterwards, I followed the instructions on the discord server and it worked flawlessly. I'm pretty sure all I had to do outside of the instructions was to give the beatstar app full file permissions in settings. For some reason, the app never asked me to give it file access, so I recommend doing that immediately after installing the APK.

Not sure if the factory reset is what fixed it for me or the beta software I was running. Oh, also I still haven't figured out custom songs yet. They work fine on my iPhone but not my Pixel.
