If the Spotify app media controls aren't working on your Samsung Galaxy S8, then you can find the fix in this post, as you simply need to tinker with various battery optimization settings.
If you're having problems with running the Spotify app on your Galaxy S8, then you can find several guides here on how to repair it, but you should know that some instructions listed there will force you to factory reset the device. If you end up factory resetting your Galaxy S8, then you should remember to backup any important data files before starting the process.

If your Spotify app media controls were previously working and they stopped after you updated your device to a new Android firmware version, then some of the OS battery optimization settings were changed by Samsung when they released it. In order to fix your device and make Spotify media controls work from lockscreen you will have to change a small option.

If you don't want to tinker with the phone's OS settings, then you can first try to uninstall Spotify and reinstall it. Also, you should first try to clear the app cache and app data, and then uninstall the app.

1. Clear Spotify app cache and app data first:

The first thing that you should do would be to clear all the settings and data your Galaxy S8 has stored for the Spotify app. This can be done easily using the following steps:

  • go to Settings.
  • open the Apps menu.
  • scroll down through the list until you find the Spotify app, open it.
  • open the Storage menu.
  • use the "clear cache" option first, then tap on "clear data" and confirm.
  • apply the changes specified in the next guide.

2. Uninstall and Reinstall Spotify:

Now you have to uninstall the Spotify app. Go to Settings> Apps> scroll through the list and find Spotify. Tap the Uninstall button and confirm. After the reboot is done you should go to Google Play Store and reinstall the Spotify app. Launch Spotify and configure it once again. Open a playlist after you launch the app and test the lock screen media controls. If the problem continues and these steps haven't helped you fix the Spotify media control problems, then you should try to apply the changes in the final guide below.

3. Disable Battery Usage Optimization for Spotify:

If the Spotify app media controls aren't working from your device's lock screen, then it might be due to a feature that all devices running Android 9 are packing, called Battery Usage Optimization. You have to create an exception for Spotify and prevent the app from being disabled when the screen of your Galaxy S8 is locked.

Here's how to disable battery usage optimization for Spotify app on the Galaxy S8:

  • go to Settings.
  • use the search bar and enter "Optimize Battery Usage" as a search term.
  • tap the "Optimize Battery Usage" and confirm.
  • tap on the "Apps not optimized" option and select "All".
  • find Spotify in the list and disable its toggle.
  • confirm and you are done.

Now your Spotify app media controls should work without any issues. If you are still having problems controlling the Spotify app from your Galaxy S8 lock screen, then you should tell us in comments. Make sure to list all the steps you took, and all the errors you're shown by Spotify, if there are any such errors.
