Samsung Galaxy S8
One UI version 1.0
Adroid version 9
My Question or Issue
The on-screen buttons (lock-screen) are not working any more.
I'm not sure if it just stoped working or maby related with an Android update (8->9) or Spotify update.
I push the buttons and it has an optical respons but dosen't do anything.
My other Playback/Stream-Apps don't have that problem, only Spotify.
I would appreciate any help you could provide.
