Finde den Equalizer Button in der App nicht bei meinem P20.
Android Version 9
Hey there @steppenwolf00,
Thanks for posting here in the Community regarding this!
We hope you don't mind us replying in English since it's the Community's official language.
Keep in mind that the Equalizer's availability on Android varies depending on the manufacturer.
There's more information regarding using the Equalizer in this Spotify Answer.
If the Equalizer is available on your device but you're having troubles enabling it in the app, we'd suggest performing a quick reinstall of the app on your device following the steps here.
If that doesn't do the trick, any screenshots of error messages you see would be helpful. Just make sure that there's no private/sensitive info displayed.
Let us know how you get on! We'll be right here if you need more help.
Have a lovely day :)
