After updating my s9+ to One Ul and also Android Pie, my AKG earphone control button , Always On Display (AOD), doesnt support changing tracks. Before update, i can use my earphone to change to the next song without unlocking my hp. Now, I only can increase or decrease the volume without unlocking, but cannot change tracks unless after unlocked the hp. Same goes to the Always ON Display. I have no this kind of issue when using Google Music. So I guess there must be some support issue after the update.

Not only that, when playing songs, suddenly the song stops. This happens on and off , maybe every once i listen a playlist.
