I have an S23 Ultra, and recently I installed the new One UI 7. Ever since, my media controls have been buggy. Whenever I turn my volume up from zero, Spotify opens and starts playing my last played song. I have made sure that Spotify is not open or in the background, and it still happens. It also doesn't matter if I have a Bluetooth device connected or not.

SOLVED:

User u/Abstract037 helped me solve this on my other post on reddit. It was a problem with another app that coincided with the update.
