I hate it when you removed 1 buds from your ear while playing music or Spotify the music pauses instead of playing continuously on the other ear. Samsung needs to fix it with updates because its annoying
mine works fine with one bud removed mid-listening to music. I think it's a settings difference.
you can reproduce the issue and report to wearable app > menu > contact us > error report.
just to be sure, check that the buds are fully up to date
